mmlu | Question:
Exercise seems to be good for the human brain,with many recent studies suggesting that regular exercise improves memory and thinking skills.But an interesting new study asks whether the apparent cognitive benefits from exercise are real or just a placebo effect -- that is,if we think we will be "smarter" after exercise,do our brains respond accordingly?The answer has significant implications for any of us hoping to use exercise to keep our minds sharp throughout our lives. While many studies suggest that exercise may have cognitive benefits,recently some scientists have begun to question whether the apparently beneficial effects of exercise on thinking might be a placebo effect.So researchers at Florida State University in Tallahassee and the University of Illinois at Urbana Champaign decided to focus on expectations,on what people anticipate that exercise will do for thinking.If people's expectations jibe closely with the actual benefits,then at least some of those improvements are probably a result of the placebo effect and not of exercise. For the new study,which was published last month in PLOS One,the researchers recruited 171 people through an online survey system,they asked half of these volunteers to estimate by how much a stretching and toning regimens performed three times a week might improve various measures of thinking.The other volunteers were asked the same questions,but about a regular walking program. In actual experiments,stretching and toning program generally have little if any impact on people's cognitive skills.Walking,on the other hand,seems to substantially improve thinking ability. But the survey respondents believed the opposite,estimating that the stretching and toning program would be more beneficial for the mind than walking.The estimates of benefits from walking were lower. These data,while they do not involve any actual exercise,are good news for people who do exercise."The results from our study suggest that the benefits of aerobic exercise are not a placebo effect," said Cary Stothart,a graduate student in cognitive psychology at Florida State University,who led the study. If expectations had been driving the improvements in cognition seen in studies after exercise,Mr.Stothart said,then people should have expected walking to be more beneficial for thinking than stretching.They didn't,implying that the changes in the brain and thinking after exercise are physiologically genuine. The findings are strong enough to suggest that exercise really does change the brain and may,in the process,improve thinking,Mr.Stothart said.That conclusion should encourage scientists to look even more closely into how,at a molecular level,exercise remodels the human brain,he said.It also should encourage the rest of us to move,since the benefits are,it seems,not imaginary,even if they are in our head. Which of the following about the placebo effect is TRUE according to the passage?
Choices:
A. It occurs during exercise.
B. It has cognitive benefits.
C. It is just a mental reaction.
D. It is a physiological response. | C |

mmlu | Question:
Robert Burns, the son of a hard-working and intelligent farmer, was the oldest of seven children. Although always hard pressed financially, their father encouraged his sons with their education. As a result, Burns not only read the Scottish poetry of Ramsay and the collections by Hailes and Herd, but also the works of Pope, Locke, and Shakespeare. By 1781, Burns had tried his hand at several agricultural jobs without success. Although he had begun writing, and his poems were spread widely in manuscript , none were published until 1786, when Burns published Chiefly in the Scottish Dialect (1786), which was an immediate success. Later Burns brought out a second edition of his poems at Edinburgh in 1787, and for two winters he was socially active in the Scottish city. In 1788 he retired to a farm at Ellis land. By 1791 Burns had failed as a farmer, and he moved to Dumfries, where he held a position as a tax collector. He died of illness at 37. Burns's art is at its best in songs such as My Heart's in the Highlands. Some of his songs, such as Auld Lang Syne and Comin' thro' the Rye, are among the most familiar and best-loved songs in the English language. But his talent was not limited to songs; two descriptive pieces, Tam o' Shanter and The Jolly Beggars, are among his masterpieces. Burns had a fine sense of humor, which was reflected in his satirical , descriptive, and playful poems. His great popularity with the Scots lay in his ability to describe the life of his fellow rural Scots. His use of dialect brought an energetic, much-needed freshness into English poetry. Robert was not officially accepted by readers until _ .
Choices:
A. 1781
B. 1786
C. 1787
D. 1791 | B |

You may have known several kinds of police --- traffic police, fire police and street police. But have you ever heard of energy-saving policeman? A group of 22 energy-saving policemen went to work last week in Beijing. They go around the city to see the use of energy in hotels, office buildings, shopping centers and other public places. One of their aims is to make sure that these places have set their air conditioning no cooler than 26degC. They also set up a special phone line so that people can tell them which buildings fail to follow the rule. "If everyone sets their air conditioning at 26degC, Beijing will save 400 million kilowatthour of electricity in one summer. That's one-third of all the usages of the city in the season," said a TV advertisement. Other Chinese cities, like Wuhan in Hubei Province and Yangzhou in Jiansu Province, are going to follow Beijing's steps in setting up a similar police team. As one of the fastest developing countries, China is using a lot of energy. This has a great effect on the country's environment and limited energy. From 1986 to 2005, the country experienced 20 warm winters continuously . Numbers show that Chinese cities have to spend billions of yuan solving environmental problems every year. At the beginning of this month, China made its first action plan to fight pollution. It aims to reduce energy usage by 20% and increase renewable energy up to 10% from 7% by 2010. To introduce the public to a green life, last week Beijing held a show on energy-saving technology and productions. Environment-friendly machines, such as a vending machine that helps collect used bottles, have attracted lots of attention. "We want to tell people that there are certain ways to protect the environment. Each of us can find effective ways to do it on our daily lives," said Liu Qianguang, an environmental engineer in Beijing. The job of the energy-saving policemen is _ .
Choices:
A. to set up a special phone line
B. to set the air conditioning cooler
C. to check the use of energy in public places
D. to make sure that more energy will be produced | C |

Now satellites are helping to forecast the weather. They are in space and they can reach any part of the world. The satellites take pictures of the atmosphere , because this is where the weather forms . They send these pictures to the weather station. So meteorologists can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change. Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon, perhaps , they may forecast the weather for a week or more ahead Why do we use the weather satellites to take pictures of the atmosphere? Because _ .

A. the weather satellites can do it easily
B. clouds form there
C. the weather forms there
D. the pictures can forecast the weather | C |
mmlu | Question:
Archery may be the oldest sport in the world. There are prehistoric drawings which show that bows and arrows were used 20 000 years ago. In early times, animals were always hunted and killed with bows and arrows. Good archers were very important when country fought against country. One of the most famous legends(,) in European history is the story of Wilhelm Tell. He was a Swiss who refused to work for an Austrian, and was ordered to shoot an apple from the head of his son. He hit the apple, and then shot the Austrian. Switzerland has been free since then, so the story goes. Archers shoot at targets at 30, 50, 70 or 90 meters' distance from them. The targets are round,80 centimeters across, and have 5 circles painted round the centre. Bows are made of steel, wood and strong plastic, and arrows of wood. The sport is enjoyed in the open air in summer and in a building in winter. Archery is good for the chest, the arms and the back. Men and women can shoot together since being strong is not so important. Women usually use lighter bows. People who can't walk or who have been ill can also enjoy it. For Zen Buddhists archery is not only a sport but also something deeper. It helps the individual to understand himself and the meaning of life. Good archers, were needed by countries in order to _ .

mmlu | Question:
Between 10,000 and 15,000 years ago, some humans discontinued their wandering hunting and gathering and settled down to farm. Grain was the first domesticated crop that started that farming process. The oldest proven records of brewing are about 6,000 years old and refer to the Sumerians. Sumeria lay between the Tigris and Euphrates rivers including Southern Mesopotamia. It is said that the Sumerians discovered the fermentation process by chance. No one knows today exactly how this occurred, but it could be that a piece of bread or grain became wet and a short time later, it began to ferment. The Sumerians were able to repeat this process and are assumed to be the first civilized culture to brew beer. They had discovered a "divine drink" which certainly was a gift from the gods. The word beer comes from the Latin word bibere, meaning "to drink", and the Spanish word cerveza originates from the Greek goddess of agriculture, Ceres. A vitamin-rich porridge, used daily, beer is reported to have increased health and longevity and reduced disease and malnutrition . The self-medicating properties of alcohol-rich beer also eased the tensions and stresses of daily living in a hostile world. The use of yeast was not yet known at that time. The success of the fermentation process was left to chance, as the brewers unknowingly relied on yeast particles in the air. Considerable scientific research took place in breweries in the 19th century. A famous work from 1876 by Louis Pasteur was Studies Concerning Beer where he revealed his knowledge of micro-organisms. By establishing that yeast is a living microorganism, Pasteur opened the gates for accurately controlling the conversion of sugar to alcohol. Another discovery in beer brewing was the work of Christian Hansen, a Danish scientist, who successfully isolated a single yeast cell and induced it to reproduce on an artificial culture medium. With the resulting yeast multiplication methods, the purity of the fermenting process has been improved. According to the text, which of the following is NOT true?
Choices:
A. Grain was the first crop used to brew beer.
B. There are some yeast particles in the air.
C. The word "beer" originates from Latin.
D. Modern beer contains more alcoholic. | D |

V _ , an artist of tremendous energy and prodigious output. He killed himself when he was only 37, but he left behind him more than 2,000 paintings and drawings, which established his reputation in a way he would never have considered possible. Van Gogh was born on March 30, 1853 at Groot Zundert Province of Noord Nrabant in Dutch. He was the son of a clergyman. His first artist impressions were formed as a boy, from his uncle who was an art dealer. The motivation bore early fruit and from the age of 12 the young Vincent was drawing. The interest led to an apprenticeship in an art dealer's firm, Groupil's, in the Hague. When he was only 20, he was transferred to the firm's London office. In London Van Gogh faced his first major crisis, when he was rejected in love. After that, he turned to religion, expressed disapproval with art-dealing and neglected his work. Groupil transferred him from London to Paris but, when his work was still unsatisfactory, dismissed him in 1876. The young Van Gogh made religion a consuming interest and during the next few years travelled in Britain, Belgium and Holland, trying to establish himself as a preacher, but without success. In 1880, at the age of 27, he found himself drawn back to art. He had a job as an assistant evangelist in the mining village of Borinage in Belgium but realized an artist drive which was to motivate him unceasingly until his death 10 years later. Late in 1881, he moved to the Hague and established a relationship with a woman, Christine Hoornik, with whom he lived for a time. He broke with her in 1883, however, and never again established a significant intimate relationship with a woman. In 1886 Van Gogh left Holland forever and travelled via Antwerp to Paris, and to major changes in artistic style. Van Gogh's work became more youthful in Paris. He lived with his brother, Theo, who managed the modern department of an art dealer's. A new, more animated, painting style emerged and the impressionist tendencies of earlier work weakened somewhat. Van Gogh developed a taste for personalized brushwork and brilliant, unmixed color1s. Among his most prominent experiments with color1 were a series of some 30 flower paintings, a fascination which stayed with him until his death. what made Van Gogh become interested in religion?
Choices:
A. That he was dismissed by Groupil
B. His experience in an art dealer's firm
C. That a girl refused his love
D. His consuming interest in art | C |
mmlu | Question:
The World Health Organization and several other United Nations agencies are calling for a major new effort to fight malaria, tuberculosis and AIDS. These three infectious diseases killed almost 6 million people last year. That is about 10 percent of the total number of deaths around the world last year. The WHO and UN agencies released a new report at the World Economic Forum in New York City earlier this month. The document says that deaths around the world from malaria and tuberculosis could be cut in half by the year 2010. It also says the number of deaths from AIDS could be reduced 25 percent within that same time period. The report is called "Calling Up the Response to Infectious Diseases." It calls for huge new investments in methods to prevent and treat infectious diseases. Officials say money is needed for research and to purchase drugs. Money is also needed to devices to prevent diseases, such as bed nets. Bed nets prevent mosquitoes that carry malaria from biting people while they sleep. David Heymann, director of the infectious disease program at the World Health Organization, says that providing effective drug treatments is important for improving peoples' health and economic well - being. Reducing disease can also help improve economic growth in developing countries. The WHO report also describes successful health programs in developing countries. In Peru, for example, the number of tuberculosis cases was cut in half by increasing the treatment to control the disease. In Vietnam, malaria was reduced 97 percent through the use of bed nets. And in Uganda, cases of the virus that causes AIDS were cut in half among pregnant women and children through the use of anti - AIDS drugs. This new international health campaign is estimated to cost about 12,000 million dollars a year. So far, officials say the campaign has about 2,000 million dollars. The WHO says the campaign will need stronger relationships among government, private aid agencies, and drug companies to succeed. We can infer from the text that reducing infectious diseases is _ .
Choices:
A. to help the countries develop better
B. to promote cooperation between countries
C. to help people get more scientific knowledge
D. to help people get a cleaner environment | A |

Microsoft founder Bill Gates has opened up about being a parent, stating that 13 is an appropriate age for a child's first cell phone. The 57-year-old, father-of-three, revealed on the Today Show that his children Jennifer and Rory were not allowed phones until their thirteenth birthday and his youngest daughter Phoebe is still waiting for one. "We've chosen in our family that it's 13 where you get a phone," the self-made billionaire explained. He said as a result his children often return home from school complaining: "All the other kids have it.I'm the only one without it, and it's so embarrassing." Asked if he keeps passwords to his son and daughters' email and Facebook accounts, Mr Gates said that he doesn't for Jennifer, 16, who he describes as "independent". He admitted that monitoring online activity is "a very tricky is sue for parents now." Despite their vast wealth Mr and Mrs Gates, who live in Lake Medina, just outside Seattle, Washington, have said they want to give their children as normal an upbringing as possible. It was previously reported that their youngsters have to complete household chores and are given a modest smount of pocket money. And in 2010 Mr Cates said that he intends to give most of his $ 61 billion fortune away rather than hand it down." _ wouldn't be good either for my kids or society," he said. Also during the Today Interview with host Matt Lauer, Mr Gates, who stepped down from Microsoft in 2008 to concentrate on philanthropy , said that helping others gives him same excitement as creating software.

mmlu | Question:
The island of Great Britain being small (compare the size of Australia), the natural place for holiday relaxation and enjoyment is extensive coastline, above all its southern and eastern coasts, and the favorite resort of the mass-population of industrial Lancashire, is on the north-west coast. Distant and little-inhabited area like Northern Scotland, are too remote for the development of large seaside resorts. For most children, going to the seaside suggests a week or fortnight of freedom on the beach, ideally a sandy one providing enough opportunities for the construction of sandcastle, fishing in pool, paddling in shallow water or swimming in deep water. Their parents spend sunny days swimming in the sea and sunbathing on the beach. Not that the British sun can be relied on and the depressing sight of families wandering round the town in old -fashioned and under umbrellas is only too common. However, there are always shops with their tourist souvenirs, plenty of cafes and if the worst comes to the worst, the cinema to offer a refuge. The average family is unlikely to seek accommodation in a hotel as they can stay more cheaply in a boarding-house. There are usually three or four-storeyed Victorian buildings, whose owners spend the summer season letting rooms to a number of couples or families and providing three cooked meals a day at what they describe as a reasonable price, with the hope that in this way they will add enough to their savings to see the winter through. Otherwise there are the camping sites for those who prefer self-catering. Nowadays, even when an increasing number of people fly off to Mediterranean resorts where a well-developed suntan can be assured, or explore in comfort Swiss lakes and mountains or romantic Italian or Spanish cities, the British seaside is still the main attraction for families, especially those with younger children. As they queue for boats trips, cups of tea or ice-cream under gray skies and in dizzling rain, the parents are reliving their own childhood when time seemed endless, their own sandcastles the most splendid on the beach, the sea always blue and friendly and the sun always hot. The reason suggested for running a boarding-house is that _ .
Choices:
A. people can live as where they live at home
B. people can cook what they are favorite
C. the owners provide three cooked meals a day at a reasonable price
D. the resulting additional income will ensure a living for several months | D |
mmlu | Question:
If the child has been brought up in a loving, openly communicative environment, the relationship with parents would be a strong one.It is only when there are ongoing troubles in the relationship between parents and the child that there is a breakdown in communication. When parents are going through difficulties in their own relationship the child sometimes develops guilt.The child can hold himself or herself responsible for the breakdown in relationship between the parents.This needs to be explained to the child, who won't speak out this guilt. The teenage years are emotionally sensitive years to the outside world.For the first time the child realizes his or her position in society.Friends suddenly become more important than parents.It is during this time that the relationship between children and parents is tested.If the bond with parents is strong, the child will not be swayed by the drug and alcohol culture.If the bond is weaker, the child will end up with problems. During such times, one of the effective ways to deal with the problems is to discuss the problem with the child.As parents, you will need to discuss the consequences of each option and then leave the final decision to the child.Forcing parental will on children is counterproductive, especially at this age.Imposing parental will at this time will stop communicating and then you will not know what is happening in their life.Whatever the problem is, the child need never be made to feel lonely.The moment that happens, the possibility of serious self-harm is raised. Any problem at this age can be dealt with by a flexible approach by parents.Discuss things calmly.Leave the decision to the individual.Make yourself available for any help or support that the child desires.The child will feel comfortable when allowed the freedom of choice. If parents have trouble with their relationship, the child _ .

mmlu | Question:
In the 1500s, South American fishermen said that the sea became warmer every few years. They gave this special event a Spanish name 'El Nino', meaning 'the baby'. It is called 'the baby' because it arrives around Christmas. El Nino is a huge area of warm water in the middle of cold water in the Pacific Ocean. It happens every two to seven years. It moves around the ocean and becomes bigger and smaller at different times. This warm water affects the weather. It is always raining over El Nino. El Nino contains a lot of energy. Scientists think this energy is formed when wind comes from the northern half of the world. The winds blow across warm sea water in the south. When the strong wind hits the warm water, violent weather happens. Scientists think that El Nino existed for many thousands of years. El Nino affects every person in the world because it affects the entire world's weather. It can bring the rain that farmers need. It can bring storms that destroy homes. It can mean that fishermen cannot catch fish, and it can bring floods. There is nothing we can do about El Nino. It is an event of nature. We can help the world's weather by trying to stop the greenhouse effect and air pollution. The most important job for scientists is to learn how to predict when El Nino is going to bring dangerous weather. Then, people can try to prepare for storms, floods and droughts. New technology like satellite pictures and temperature measuring equipment can help. Still, it is very hard to say when or where El Nino will cause damage. It happens _ .

Air pollution, such as haze, has become a serious problem around the world. Besides wearing a mask, what else can we do to protect ourselves from the dirty air? Scientists have developed a new inhaler that can reduce the effect air pollution has on people. It could help millions of people who are suffering from air pollution,the Guardianreports. This inhaler is developed by German company Bitop and contains a molecule named Ectoine. The molecule creates a layer that protects lungs from polluted air. It's reported that the inhaler will be affordable to most people when it comes to the market. Air pollution kills more than three million people a year worldwide and leads to health problems like lung and heart disease and strokes, according to a 2016 research project in the journalNature. It is also linked to brain disease, mental illness and diabetes . Andreas Bilstein at Bitop believed that the inhaler could be useful around the world, because air pollution is not just a European problem: "Especially in Asia - China in particular - the demand for such a product is even higher." Many Chinese cities have been suffering from haze. According to World Health Organization, two of the 10 most polluted cities in the world in 2015 were in China. About 800,000 deaths that are linked to air pollution take place in the country every year. However, such inhalers should never be an excuse for not trying to stop air pollution, said Professor Jean Krutmann at the Leibniz Research Institute for Environmental Medicine. "The best thing is that we have clean air and we don't need any prophylactic treatment," he said. Which of the following is NOT true?

A. Air pollution kills millions of people a year worldwide.
B. Air pollution can cause mental illness.
C. There are no air pollution problems in Europe.

mmlu | Question:
Many environmentalists and entrepreneurs are looking for ideas on how to "capture gold" -- that is, how to collect and convert plastic waste into new plastic or fuel. OK, describing plastic waste as potential "gold" may be overdoing it. But the campaigners say that publicizing the notion that plastic is worth something may help reduce the amount of waste that ends up in oceans and the bellies of sea creatures. To that end, they have set up a competition inviting members of the public to submit ideas online. Organizers will take the best ones to the Rio+20 Earth Summit in Rio de Janeiro next month, where they are planning a daylong side event called Plasticity focusing on issues related to plastic pollution. The plastic waste problem is gaining broader attention as environmentalists, scientists, manufacturers and the public become more aware of the sheer volume of the stuff that finds its way into the sea. More than 260 million metric tons of plastic are now produced per year, according to the trade association PlasticsEurope. The majority of that is not recycled. Most of it ends up in landfill, and a significant amount ends up as litter on land, in rivers and in the oceans. Technological advances have made clear that it is possible to reuse much of this plastic by turning it into fuel or new products. Yet the companies that have come up with such solutions have not achieved the economies of scale that would allow them to function profitably. Insufficient waste-collection and recycling systems in most countries also stand in the way of " _ " concept, said Doug Woodring, an environmental entrepreneur in Hong Kong who is among the organizer of the Plasticity forum in Rio. Rather than breast-beating, the form aims to highlight some of the technologies and ideas out there for collection and reuse. My personal favorite for now is a vacuum cleaner with plastic parts made from plastic waste. According to Doug Woodring, the companies that want to reuse plastic waste _ .
Choices:
A. have collected enough waste to be used
B. have no practical solutions
C. haven't reached profitable scale

Remember when a trip to the supermarket was nothing more than a boring thing requiring little or no specialized knowledge? You could send your kids into a cart while you did shopping. You always bought the same brands,usually the brands your mother bought. You didn't know about unit pricing,and furthermore,you didn't care. It never occurred to you to read the labels on anything. After all,you'd bought these things a hundred times. But now,I really look on those days with a feeling of yearn . How innocent we were! How carefree were those trips to the supermarket. No worries. Today a trip to the supermarket is filled with social influence. Every time I buy pork chops I think about the years I'm shaving from my life. I keep a careful eye on the freshness date and examine the tamper-proof packaging. I am victim of that most dangerous social disease:shoppers' panic. I didn't realize how serious my condition had become until the last time I needed laundry, soap. It seemed simple enough. Just run into the market,grab a box of the old reliable and pay for it. I hadn't planned on discovering Ecover,a new brand of laundry soap. It sat quietly on the shelf right next to my old reliable. "Healthy,gentle but effective. "My respect for it deepened with each new claim as I read the entire package. Then I looked at the price:$5. 69 for 2 pound. $5. 69! I cast a quick glance at the old reliable,still on sale for$1. 39. Six bucks for laundry soap! These people must be crazy! Who's going to pay six bucks for laundry soap? It's not as though I can't afford it. See,it's concentrated--use less,get more. BUT SIX BUCKS! And the box is made from recycled materials ...This act went on for a solid half hour,after which I left the shelf without any soap at all. Surely the meat department is most threatening place. Remember what protein was good for you? That's all over. Every bite you take kills you. I won't even mention meat's moral influence. When all is said and done,we still must eat. I gather up my healthy-cooking oil and my recycled paper towels and head to the checkout counter. Recalling the old days' shopping in the supermarket,the author thinks it was_.
Choices:
A. pleasant
B. fresh
C. dangerous
D. crazy | A |

Do you suppose Darwin, one of the greatest scientists of all time, really did fools' experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish? Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important. Charles Darwin didn't settle for just thinking he knew something. And, he believed all things could be important however simple they seemed to be. Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn't be worth anything. But this simple experiment is important. It explains part of our present day understandings of physics ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics. Scientist sometimes stops to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science. The passage tells us that Charles Darwin_.
Choices:
A. was a great English scientist
B. always liked doing the experiments that others thought difficult
C. thought even the simplest thing was important
D. didn't get well with others | C |

Based on cultural traditions and the changing face of contemporary British communities, the Festival of Muslim Cultures joins young people from Muslim and non-Muslim backgrounds together through the creation of innovative , high quality cultural activities. We have been working with arts and educational institutions across the UK to promote the mainstreaming of Muslim cultures within UK everyday life. The Festival was created out of the need to encourage a better understanding between Muslims and non-Muslims, to promote respect for Muslim cultures and to show how culture creates the pathways that connect us all together. The program launched with a visit by the Festival's patron , the Prince of Wales, to the exhibition "Palace and Mosque" in Sheffield and since then there have been more than 100 events that have ranged from a Somali community day in Cardiff at the National Museum of Wales to a late-night Dance with Radio Tarifa (from Spain) and Dimi Mint Abba (form Mauritania) in the Royal Albert Hall and from a home-grown play in Nottingham about the Kashmir earthquake to the exhibition"Beyond the Palace Walls" at the Royal Museum Edinburgh of Islamic art from the Hermitage Museum, St Petersburg. We are now working on a number of long-term projects which stay true to our commitment to promoting Muslim cultures through arts collaborations and build on the extensive network of local, national and international partners that Festival has created. These include a three-year national program that connects young Muslims to their local cultural institutions; a UK Muslim cookbook; an exhibition of the Ottoman architect Sinan; and a project for schools around the 1000-year old story "The Animals' Lawsuit against Humanity". For more information about the Festival, please click on another page: Who's Who. The best title of this passage would be _ .

Let's face it.No one drinks diet soda for the taste.People drink diet soda in the hope that it will help them lose weight or at least keep them from gaining it.Yet it seems to have exactly the opposite effect, according to a new study. Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet soda."What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler. The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly l0 years. While the findings are surprising, they also offer some explanations. Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet soda, they don't lose weight at all."We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers. So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet soda, and so over-compensate for the missing calories. A related study found some sweeteners raised blood sugar levels in some mice."Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P.Hazuda, professor at the University of Texas's school of medicine." _ may be free of calories, but not of consequences." The new study suggests that drinking diet soda _ .

A team of US psychologists have found that talking to another person for ten minutes a day helps with memory. "Socializing is just as effective as more traditional kinds of mental exercise in memory and intellectual performance," Oscar Ybarra, a psychologist at the University of Michigan Institute for Social Research, said in a statement. In one investigation, they analyzed data on 3610 people, aged 24 to 96. They found that the higher their level of social interaction , the better their cognitive functioning. Social interaction includes getting together or having phone chats with relatives, freinds and neighbors. In another experiment, the researchers conducted lab tests on 76 college students, aged 18 to 21, to evaluate how social interactions and intellectual exercises affected the results of memory and mental performance tests. The students were divided into three groups: the social interaction group had a discussion of a social issue for 10 minutes before taking the tests; the intellectual activities group completed three tasks (including a reading comprehension exercise and a crossword puzzle) before the tests; and a control group watched a 10-minute clip of the Seinfeld television show. "We found that short-term social interaction lasting for just 10 minutes improved participants' intellectual performance as much as engaging in so-called 'intellectual' activities for the same amount of time," Ybarra said. The study was expected to be published in the February issue of the journal Personality and Social Psychology Bulletin. What's the purpose of the experiment on 76 college students?
Choices:
A. To judge the effect of social interaction on memory and intelligence.
B. To find out what is real social interaction.
C. To learn how much time is needed for social interaction.

All around the world, people drink tea. But tea does not mean the same thing to everyone. In different countries people have very different ideas about drinking tea. In China, for example, tea is always served when people get together. The Chinese drink it at any time of the day at homes or in teahouses. They prefer their tea plain, with nothing else in it. Tea is also important in Japan. The Japanese have a special way of serving tea called a tea ceremony . It is very old and full of meaning. Everything must be done in a special way in the ceremony. There is even a special room for it in Japanese homes. Another tea-drinking country is England. In England, the late afternoon is "teatime". Almost everyone has a cup of tea then. The English usually make tea in a teapot and drink it with milk and sugar. They also eat cakes, cookies and little sandwiches at teatime. In the United States people drink tea mostly for breakfast or after meals. Americans usually use tea bags to make their tea. Tea bags are faster and easier than making tea in teapots. In summer, many Americans drink cold tea -- "iced tea". Sometimes they drink iced tea from cans, like soda. ,. Tea is popular _ .

Their thumbs sure must be sore. Two central prefix = st1 /Pennsylvaniafriends spent most of March in a text - messaging record attempt, exchanging a thumbs-flying total of 217,000. For one of the two, that meant an inches-thick itemized bill for $ 26,000. Nick Andes, 29, and Doug Klinger, 30, were relying on their unlimited text messaging plans to get them through the escapade , so Andes didn't expect such a big bill. " It came in a box that cost $ 27.55 to send to me." he said. He said he "panicked" and called T-Mobile, which said it would investigate the charges. The two Lancaster-area residents have been practically non-stop texters for about a decade since they attended Berks Technical Institute together. That led Andes to searching for the largest monthly text message total he could find posted online: 182,000 sent in 2005 by Deepak Sharma in India. Andes and Klinger were able to set up their phones to send multiple messages. During a February test run they found they could send 6,000 or 7,000 messages on some days, prompting the March messaging marathon. " Most were either short phrases or one word, 'LOL' or 'Hello', things like that , with tons and tons of repeats," said Andes, reached by phone. Andes sent more than 140,000 messages, and Klinger sent more than 70,000 to end the month with a total of just over 217,000, he said. A spokesman for Guinness World Records didn't immediately return messages asking whether it would be certified as a record. April came as a relief to Andes' wife , Julie, who had found his phone tied up with texting when she tried to call him on lunch breaks. " She was tired of it the first few days into it, "Andes said.

A. The two young men set a new Guinness World Record by sending 217,000 messages.

Some time ago, a friend of mine punished his three-year-old daughter for wasting a roll of gold wrapping paper. Money was tight , and he became infuriated when the child tried to decorate a box to put under the Christmas tree. Nevertheless, the little girl brought the gift to her father the next morning and said, "This is for you, Daddy." He was embarrassed by his earlier over-reaction, but his anger flared again when he found that the box was empty. He shouted at her loudly, "Don't you know that when you give someone a present, there's supposed to be something inside of it?" The little girl looked up at him with tears in her eyes and said, "Oh, Daddy, it's not empty. I blew kisses in the box. I filled it with my love. All for you, Daddy." The father was crushed. He put his arms around his little girl, and he begged her for forgiveness . My friend told me that he kept that gold box by his bed for years. Whenever he was discouraged, he would take out an imaginary kiss and remember the love of the child who had put it there.

Four months after my company was set up, I had only a quarter of the starting capital left in the bank. Looking for guidance, I went to talk to my friend, Arthur Walworth about my new venture. "Times of great change always bring out the risk-takers," he said. "And they leave winners and losers. My grandfather invested a lot of money in a project of Thomas Edison's that ended up in failure.

mmlu | Question:
Utopia is a perfect place. It is a place without war, hunger, poverty, or crime. It is a place where the people work together and share. There is no money in Utopia because the people do not need money. They do not have personal possessions because everything belongs to everyone. All of the people are equal in Utopia, and the laws are all fair. Utopia is not a new place. Plato, the ancient Greek philosopher, described a perfect society in his famous dialogue The Republic. In Plato's Republic, philosophers were the kings, and every person had a place in the society. In 1516, Sir Thomas More wrote about an island in the Pacific Ocean where everything was perfect. He named the island " Utopia". In 1602, Tommaso Campanella wrote The City in the Sun about a perfect community on the island of Ceylon ( now Sri Lanka ) ; and in 1872, Samuel Butler wrote a novel about a perfect country which he named " Erewhon". " Utopia" is a Greek word that means " not a place", and "Erewhon" is the English word " nowhere" spelled backwards. Utopia is a perfect place, but it is not a real place. Most 'real' Utopias last only a short time. This is because everyone wants to live in it, but no one knows how to make it work. As a result, when we say something is ' Utopia' today, we mean that it is a good idea, but it is not realistic. Which of the following would be the best title for this passage?

A. A place without war
B. A Good Idea
C. A Perfect Place

I know what you're thinking : pizza ? For breakfast? But the truth is that you can have last night's _ in the a. m. if you want to. I know lots of women who skip breakfast , and they have a ton of different excuses for doing it . Some say they don't have time, others think they're "saving" calories , still others just don't like breakfast food . But the bottom line is that eating in the morning is very important when you're trying to lose weight. "Eating just about anything from 300 to 400 calories would be better than nothing at all," says Katherine Brooking , R , D , who developed the super-easy eating plan for this year's "SELF CHALLENGE". And even pizza can be healthy if it's loaded with vegetables, and you stick to one small piece. Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal. So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night's leftovers-it may sound crazy, but if it works for you, do it! I find if I tell myself, "You can always eat it tomorrow," I put away the leftovers instead of eating more that night. Try it...you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects. What's the writer's attitude towards eating breakfast?

Although many online personality tests are fun, only a few will really give you into who you are and what you are supposed to be doing with your life. At CareerPlanner.com we believe that each individual, regardless of race or religion, has a purpose in life, and until you discover what your purpose is, you will not find true happiness, nor true job satisfaction. This doesn't mean you won't be successful. It just means you won't be happy until you are moving towards your true purpose. Unfortunately, our school system does very little to help students discover their true career. This is where online personality tests and career tests can help. Online personality tests and career tests can help you better understand what type of work you should be doing to achieve job satisfaction, happiness, and success. Personality tests are most useful in giving you insight into "how" your personality compares to others and "how" you like to work. In particular, if you frequently experience difficulty working with others, or getting their support and cooperation, a really good personality test would show you how to get along better. While personality tests are very useful at showing you how you like to work and how you like your work environment, they are not really designed to show you "what" type of work is right for you. That is where Career Interest Tests come in. Online Career Tests, such as the CareerPlanner.com offers will help you discover what your true interests are, and what type of work you will be passionate about. But back to personality tests. The most well-established personality tests are the Myers-Briggs Type Indicator R, and the Enneagram. You can't achieve true job satisfaction unless you _ .

Learning a second language can improve brain power, scientists believe. US researchers from Northwestern University say bilingualism is a form of brain training -- a mental "work out" that adjusts the mind finely. Speaking two languages well affects the brain and changes how the nervous system reacts to sound, lab tests showed. Experts say the experiment performed by the National Academy of Sciences provides "biological" evidence of this. In an attempt to prove the guess that speaking two languages is good for one's mind, the team monitored how the brain of 48 healthy student volunteers reacted to different sounds. Twenty three of these volunteers were bilingual. The scientists used special equipment to trace the pattern of brainwaves. Under quiet, laboratory conditions, the bilingual students responded in a similar way to the English-only-speaking students, who formed the control group. But the bilingual group were far superior at processing sounds even when there were a lot of people talking in the room. They were better able to focus on to the important information -- the speaker's voice -- and block out other _ noises. Prof Nina Kraus, who led the research, said: "The bilingual's better experience with sound results in a hearing system that is highly efficient, flexible and focused in its automatic sound processing, especially in challenging or novel listening conditions." Co-author Viorica Marian said: "People do crossword puzzles and other activities to keep their minds sharp. But the advantages we've discovered in double language speakers come automatically simply from knowing and using two languages.'' Musicians appear to gain a similar benefit when rehearsing , say the researchers. According to some theories, being bilingual might help avoid dementia . How was the bilingual group better at processing sounds?
Choices:
A. They were the control group.
B. They could better fix their attention on something of importance.
C. They were able to find the speaker's voice quickly.
D. They had better nervous system. | B |

Important changes took place in the lives of women in the 19th century. When men went out from their farms to cities to seek jobs in industry, peasant women had to take over the sowing, growing, and harvesting of the fields as well as caring for cattle and raising their children. When women also moved to the cities in search of work, they found that it was increasingly separated by sex and that employment opportunities for women were limited to the lower-paid jobs. Later in the century, women in industry gathered mainly in cloth-making factories, though some worked in mining or took similarly difficult and tiring jobs. In the 1800s, service work also absorbed a great number of women who arrived in the cities from the country. Young women especially took jobs as servants in middle-class and upper-class homes; and as more and more men were drawn into industry, domestic service became increasingly a female job. In the second half of the century, however, chances of other service work also opened up to women, from sales jobs in shops to teaching and nursing. These jobs came to be done mainly by women. For thousands of years, when almost all work was done on the family farm or in the family firm, home and workplace had been the same. In these cases, women could do farm work or hand work, and perform home duties such as child care and preparation of meals at the same time. Along with the development of industry, the central workplace, however, such as the factory and the department store, separated home from work. Faced with the necessity for women to choose between home and workplace, Western society began to give particular attention to the role of women as homemakers with more energy than ever before. This passage is about _ in the 19th century.
Choices:
A. service and industry
B. female and male
C. women and their work
D. male jobs and the pay | C |

In eighteen seventy-seven,the American government decided to move the Nez Perce Indians from their land. The government had set up a reservation for them in Idaho. Chief Joseph did not want to leave the land. It was holy ground. It contained the bones of his father and mother. But,like his father in earlier times,Chief Joseph knew it would be hopeless to stay and defend the land. There were too few Indians to win a war against the white men. And so in June of eighteen seventy-seven,the Nez Perce left their home in the Wallowa Valley. They left quickly. They were able to take only a small part of what they owned,and just a few cattle and Appaloosa horses. When the Indians reached the Snake River,the water was very deep and ran very fast with melted snow from the mountains. Chief Joseph and his people made boats from sticks and dried animal skins to cross the river. While the Indians were busy,a group of white men came and stole some of the cattle waiting at the edge of the river. The other chiefs demanded that Joseph call a meeting. Two of the chiefs,White Bird and Toohoolhoolzote,spoke for War,but Joseph held different opinion. Some of the young men in White Bird's group were very angry. That night,they rode into the countryside and killed eleven white persons. During all his years as chief,Joseph had tried to keep the peace. Now he saw there was no hope. Although he and his young men had taken no part in the killings,he knew that the white men would blame all of the Indians. Chief Joseph said,"I would have given my own life if I could have undone the killing of the white men." Many Nez Perce fled. Chief Joseph remained,because his wife was about to have a baby. After she gave birth,he and his family joined the others in White Bird Canyon to the south. Joseph wanted to lead the people to safety in the flat lands of Montana. But the United States army quickly sent horse soldiers to follow them. They were extremely tired when they reached White Bird Canyon. An Indian--carrying a white flag--walked forward to meet them. A soldier shot him. With that shot,war between the Nez Perce and the United States began. What might be the title of the passage?

I grew up in Lakeland, Louisiana, one of 7 children. We all lived on my parents' farm. At 12, I got a part-time job--milking cows to help support the family. I milked cows at five in the morning and again at two in the afternoon, seven days a week. In the kitchen one Saturday before daytime, I remember complaining to my father and grandfather about having to go milk those cows. My father said, "You know, boy, to work is a blessing ." Going to college was rare for a kid from Lakeland, Louisiana. "Pick something that you like doing to study, and you will always look forward to your work," my father told me. But he also added, "Even having a job you hate is better than not having a job at all." I wanted to be a farmer, but I joined the ROTC program to help pay for college. And what started out as an obligation to the army became a way of life that I was devoted to for 37 years. In the late 1980s, during a visit to Bangladesh, I saw a woman with a baby on her back, breaking bricks with a hammer. I asked a Bangladesh military officer why they weren't using a machine. He told me a machine would make that lady unemployed . Breaking those bricks meant she could earn enough money to feed herself and her baby that day. He told me bad as that woman's job was, it was enough to keep a small family alive, which reminded me of my father's words. I'm retired from the army, but I'm still working to help people be prepared for disaster. I'm not going to stop. I believe in my father's words. I believe in the blessing of work. What can we learn about the writer's first part-time job?

A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces that could be taken off when users click their heels together. It's been 26 years since we saw them magically tightening Marty McFly's Nike boots in the film Back to The Future. Now,self-tying shoelaces could actually become a reality this year,proving right one of the film's fantastical predictions for what 2015 would be like. Engineers have designed a shoe that can automatically lace up,adjusting itself to the shape of your foot. Simply slip the controller on and pressure sensors will tell the 'smart shoe' when your foot is in position,triggering a tiny motor in the heel that pulls the laces tight. When you want to take off the shoes,you click your heels together twice and the motor will release a spring in the shoe's tongue,which loosens the laces enough for you to slip them off. And the invention doesn't even need to be plugged in to charge or have its battery replaced because it runs on power generated by the swing of your foot as you walk. Engineer K1evis Ylli,of the Institute for Micromachining and Information Technology in southern Gemany,said the shoes could help a variety of different people.[:Zxxk.Com] "One focus is that it could be used in shoes for elderly people who have mobility problems,"he said."But it could also work for children,or as a lifestyle product.". The design,which is still in a prototype stage,cleverly gets the energy of the foot's swing when opposing magnets in each shoe move past each other. It then uses that power to charge a battery.An hour of walking is enough to tighten the laces once,and it requires no energy to undo the shoes because that relies on the spring alone. Which of the following can be the best title of the text?
Choices:
A. A fantastical prediction
B. A great invention in Germany
C. A shoe with self-tying laces
D. A popular lifestyle product | C |
mmlu | Question:
This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu oil mixed with 80% conventional jet fuel. What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions from airplanes. there are a lot of hurdles that still need to be overcome. First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet'A'fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same. The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter - the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up. However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae produced in sewage treatment plants, not from food sources. Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel-a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project. While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen! .Why does Virgin Airlines try to replace normal fuel with biofuel?
Choices:
A. To cut down the flight cost of the company.
B. To remove some hurdles for the biofuel to work.
C. To reduce CO 2 emissions from airplanes.
D. To test plane engines on biofuel. | C |

"Iris scan , please," the bank's computer voice tells you . You step up and the computer reads your eye , comparing it to the stored file it has of your iris. The images had better match--otherwise you won't be able to get your money. Iris scanning and other technologies , such as fingerprint and voice scanning , have appeared in many science fiction movies in the past. Today , these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics a fast developing area of automatic personal identification technology . Basically , biometrics uses various ways to verify a persons identity , based on the individual's unique characteristics ,including fingerprints , voices, irises, body heat patterns, facial images, handprints , signatures and so on. Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember , forget, lose or steal. The voice scan is the simplest and most affordable form of biometrics . It only requires a computer, a microphone and the correct software. The software records a subject's voice and then compares it to a stored voice sample for identification purposes. For additional safety, fingerprint and handprint scans can also be employed . Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand. Iris scans currently give the highest level of accuracy among all the available biometrics systems. Another technology , full facial scans , is currently in use at border crossings and airports. Facial scanning equipment can actually track and identify moving faces within a crowd. The potential of biometrics is exciting and encouraging . With continued development , testing , and application , current technologies will become even more effective in the future. Soon , the days of password and car keys will be gone . Just don't leave home without your fingerprints! What is the author's attitude towards the future of biometrics?

mmlu | Question:
Sometimes people call each other " scared cat" , but have you ever thought about this expression? When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its blood-stream. If the danger continues, this animal will do one of the two things. It will defend itself, or it will run away as fast as it can. Something like this also happens to people. When we are excited, angry, scared, or aroused by other emotions, our bodies go through many physical changes. Our hearts beat faster, and our muscles get tense. All of these changes make us more alert and ready to react. We, too, get ready to defend ourselves or run. Human beings, however, have a problem. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger - and regretted later? Have you ever shouted at a teacher or told somebody you were lonely and then wished later you had kept your mouth shut? It isn't always wise to express your feelings freely. Does this mean that it's always smarter to hide our feelings? No! If you keep feelings like anger hidden away or bottled up inside, your body stays tense. Physical illnesses can develop, and you can feel disturbed badly inside. _ can actually be bad for your health. Feelings that you keep all bottled up inside don't just go away. It's as if you bought some bananas and stuck them in a cupboard. You might not be able to see them, but before long you'd smell them. And if you opened the cupboard, chances are you'd see little fruit flies hovering all over them. They'd be rotten. You can try to treat emotions as if they were bananas in the cupboard. You can hide them and you can pretend they don't exit, but they'll still be around. And at last you'll have to deal with them, just like those bananas. The author mainly intends to tell us to _ .

Some time ago, a friend of mine punished his three-year-old daughter for wasting a roll of gold wrapping paper. Money was tight , and he became infuriated when the child tried to decorate a box to put under the Christmas tree. Nevertheless, the little girl brought the gift to her father the next morning and said, "This is for you, Daddy." He was embarrassed by his earlier over-reaction, but his anger flared again when he found that the box was empty. He shouted at her loudly, "Don't you know that when you give someone a present, there's supposed to be something inside of it?" The little girl looked up at him with tears in her eyes and said, "Oh, Daddy, it's not empty. I blew kisses in the box. I filled it with my love. All for you, Daddy." The father was crushed. He put his arms around his little girl, and he begged her for forgiveness . My friend told me that he kept that gold box by his bed for years. Whenever he was discouraged, he would take out an imaginary kiss and remember the love of the child who had put it there. In a very real sense, each of us as parents has been given a gold container filled with unconditional love and kisses from our children. There is no more precious possession anyone could hold.

Astronomers say they are on the point of finding planets like Earth orbiting other stars, which is a key step in determining if we are alone in the universe. A top NASA official and other leading scientists say that within four or five years they should discover the first Earth-like planet where life could develop, or may have already. A planet close to the size of Earth could even be found sometime this year. At the annual American Astronomical Society conference this week, each discovery involving so-called "exoplanets" --those outside our solar system -- pointed to the same conclusion:Quiet planets like Earth where life could develop probably are plentiful. NASA's Dew Kepler telescope and a lot of new research from the suddenly hot and competitive exoplanet field caused noticeable buzz at the meeting.Scientists are talking about being at "an incredible special place in history" and closer to answering the question. "Are we alone? For the first time, there's an optimism that sometime in our lifetimes we're going to _ that," said Simon Worden,an astronomer who heads NASA's Ames Research Center. "If I were a betting man, which I am, I would bet we're not alone." "These are big questions that reflect upon the meaning of the human race in the universe," the director of the Vatican Observatory, the Rev.

Plastic surgery is becoming popular with young people. But just a few days ago, it took the life of a pop singer in China. Wang Bei, 24, a former singer on Super Girl, died on Nov 15 during plastic surgery in Wuhan, Hubei province. The young singer's jaw suddenly started bleeding during the procedure, blocking her throat and causing her to suffocate. The Ministry of Health stepped in on Nov 27, calling on health authorities all over China to increase supervision of the country's medical plastic surgery industry. It also told the Hubei health department to look into Wang's death and "to make the results of the investigation public as soon as possible" Wang's death has raised concerns about the dangers of plastic surgery in China. In China, people, especially youngsters, are becoming more and more conscious of their looks and are willing to _ to make themselves look more attractive. Today, many young people see plastic surgery as the key to love, wealth and success. Ding Xiaobang, a plastic surgeon at the Peking Union Medical College Hospital, said that in the past decade, he had seen a growing number of patients, like Wang Bei, who were young and naturally good-looking. "They want to improve their appearance to find better opportunities in work and in marriage," said Ding. Zhao, 23, a student at the Beijing International Studies University, spent 3,000 yuan on a eyelid tuck before graduating this year. She said: " Of course I want to look prettier. I want to make a good impression on potential employers." Ding also owed this trend to frustration. "Some are frustrated with life and use surgery as a way to try and recover," said Ding. But a lot of people ignore the risk and danger of plastic surgery. In 12 years as a doctor, Zhu Wenbo from Chengdu has often seen unsuccessful plastic surgeries." I've met several people whose faces were ruined by plastic surgery, and helping them recover is difficult," said Zhu. Being yourself is the most beautiful thing in the world. But if you are considering plastic surgery, here is some advice from experts: 1. Choose qualified hospitals, especially those with a good reputation for plastic surgery. Avoid beauty salons. 2. Do not expect too much from changing your appearance. It can only change your face or another body part in certain ways. And safety should always come first. What is NOT the reason for so many young people go to plastic surgery?

A. to make themselves more attractive
B. to improve their appearance and find better job opportunities
C. to seek better opportunities in marriage.

mmlu | Question:
Linking the Red Sea to the Indian Ocean, the blue waters of the Gulf of Aden near Somalia are one of the most important trading routes in the world. But they are also the most feared. Pirates whose targets are ships and their crew often show up there. On September 25, a Ukrainian ship carrying 30 tanks became another victim. The pirates have reportedly killed one of the crewmen and are now surrounded by the US Navy. But they are still demanding $ 20 million for the release of the ship. This year alone, more than 50 ships have been attacked, 25 hijacked , and 14 are currently being held. Of course this is nothing new either. Ever since there has been water and ships there have been pirates. The earliest documented history of pirates dates back to the 13th century in the Mediterranean Sea. Even the famous Roman emperor Julius Caesar was kidnapped by pirates at one time. Piracy reached its peak in the early l700s, especially in the Caribbean and off the coast of Africa. In the mid-20th-century, most pirates we're common thieves. They used hooks to steal on board commercial ships, and took all that they could find. These pirates were more likely to flee than fight if met by the crew. However, nowadays piracy has become a multi-million dollar business attracting many in poor countries such as Somalia. "The pirates are well funded and have all the latest equipment, including satellite phones," said a top UN representative in Somalia. In Asia, however, a trend started where pirates didn't just want to kidnap the stuff, they also wanted to control the ship. They would kill the crewmembers or kidnap them for ransom . After the recent kidnapping of Ukrainian ship, people are also worrying that tanks and arms on board would fall into hands of terrorists. Last week the UN called a meeting from all affected countries to fight piracy. "The international community is determined to stop these pirates who are weakening efforts to bring peace to Somalia. This cannot and will not be allowed to continue," a representative said. Which of the following is TRUE about piracy?
Choices:
A. It was recorded that pirates started to attack ships in Somalia in the 13th century.
B. Back in the mid-20th century pirates did not appear so harmful as today's.
C. Once a ship is attacked, it will be hijacked by pirates.

Scientists have proved that sleeping and learning go hand in hand. Even a short nap can boost our memory and sharpen our thinking. But the relationship goes deeper than that. "The brain is not passive while you sleep," scientist Anat Arzi said. "It's quite active. You can do many things while you are asleep." Arzi and her coworkers didn't try to teach the sleeping volunteers any complex information, like new words or facts. Instead, the scientists taught volunteers to make new connections between smells and sounds. When we smell something good, like a flower, we take deep breaths. When we smell something bad, we take short breaths. Arzi and her co-workers based their experiment on these reactions. Once the volunteers fell asleep in the lab, the scientists went to work. They gave them a whiff of something pleasant and meanwhile played a particular musical note. They didn't wake up, but they heard--and sniffed deeply. Then the scientists gave the volunteers a whiff of something terrible and played a different musical note. Again, the volunteers heard and smelled--a short snort this time--but didn't wake up. The researchers repeated the experiment. After just four repetitions, volunteers made a connection between the musical notes and their paired smells. When the scientists played the musical tone that went with good smells, the sleepers breathed deeply. And when the scientists played the musical tone that went with bad smells, the sleepers breathed briefly--despite there being no bad smell. The next day, the volunteers woke up with the sound-smell connection. They breathed deeply when hearing one tone and cut their breaths short when hearing the other, which must have been unusual for them. Imagine walking down the street and taking a deep breath upon hearing a particular sound! How did the volunteers react when smelling something nice and hearing musical notes?
Choices:
A. They took a deep breath.
B. They had a wonderful dream.
C. They woke up at once.

In 1970, Oscar, owner of a 100-acre tract, prepared and duly recorded a subdivision plan called Happy Acres. The plan showed 90 one-acre lots and a tenacre tract in the center that was designated "Future Public School." Oscar published and distributed a brochure promoting Happy Acres which emphasized the proximity of the lots to the school property and indicated potential tax savings "because the school district will not have to expend tax money to acquire this property." There is no specific statute concerning the dedication of school sites. Oscar sold 50 of the lots to individual purchasers. Each deed referred to the recorded plan and also contained the following clause: "No mobile home shall be erected on any lot within Happy Acres." Sarah was one of the original purchasers from Oscar.

A Tchaikovsky concerto is what made Romel Joseph fall in love with the violin. He learned how to play in Haiti, where he was born, but a Fulbright scholarship brought him to the United States, and he finally earned a master's degree, reports CBS News reporter Katie Couric. Music had changed his life. He wanted to do the same for the children of Haiti. Joseph built a school in Port-au-Prince nearly 20 years ago.

A deal has been signed to turn by-products from a Scottish distillery into fuel for cars. In what is declared to be a world first, the Tullibardine distillery in Perthshire has linked up with a spin-out company from Napier University in Edinburgh. They plan to use bacteria to feed on the "leftovers" from the whisky making process. This will produce butanol which can be used to fuel vehicles. More than 90% of the stuff that comes out of a whisky distillery is not whisky. It is leftovers like draff and pot ales -- both produced in the early stages of the process. They are high in sugar and are currently used for things like fertiliser and cattle feed. Napier University's Biofuel Research Centre (BfRC) has already shown that the right bacteria can feed on those by-products to produce butanol--a direct replacement for vehicle fuel. Now the spin-out company, Celtic Renewables, and independent whisky producer Tullibardine have signed an agreement. Together they will apply the process to thousands of tons of the distillery's leftovers. Professor Martin Tangney, founder of Celtic Renewables, said "Our partnership with Tullibardine is an important step in the development of a business which combines two important Scottish industries -- whisky and renewables. This project shows that creative use of existing technologies can _ resources on our doorstep to benefit both the environment and the economy." Douglas Ross, managing director of Tullibardine, which spends PS250,000 disposing of its by-products every year, said "We are delighted to be partnering Celtic Renewables in this creative business, the obvious benefits of which are environmental. It takes a cost to us and turns it into something that has social as well as commercial value." The project is being supported by a grant from the Scottish government's Zero Waste Scotland initiative. Celtic Renewables said it eventually aimed to build a processing plant in Scotland, with the hope of building an industry that could be worth PS60m a year. How do people deal with whisky leftovers at present?

A. They throw them away.
B. They use them to feed people.

It's an annual argument. Do we or do we not go on holiday? My wife says no because we have no savings to save us. I say you only live once and we work hard and what's the point if you can't go on holiday. The joy of a recession means no argument next year - we just won't go. Since money is known to be one of the things most likely to bring a relationship to its knees, we should be grateful. For many families the recession means more than not booking a holiday A YouGov survey of 2, 000 people found 22% said they were arguing more with their partners because of concerns about money. A recent research shows arguments about money were especially damaging to couples. Kim Stephenson, an occupational psychologist, believes money may be different things to men and women. "People can say the same things about money but have different ideas of what it's for." he explains. "They'll say it's to save, to spend, for security, for freedom, to show someone you love them." He says men are more likely to see money as a way of buying status and of showing their parents that they've achieved something. "The biggest problem is that couples assume each other know what's going on with their finances, but they don't. There seems to be more of a taboo about talking about money than about death. But you both need to know what you're doing, who's paying what into the joint account and how much you keep separately. In a healthy relationship, you don't have to agree about money, but you have to talk about it." The author suggests that couples should _ .

A. put their money together instead of keeping it separately

The tea gardens in Sri Lanka are actually large estates . The best tea usually comes from plants grown on high grounds, the cool hilltops with rows and rows of tea plants. The plants are about one metre apart. The plant is often pruned so that it remains only 60 to 90 centimetres high. _ is important because it encourages the growth of tender hoots, or young leaves. It is from these shoots that the best in got. Practically all the tea pickers are women. The estates like to employ women pickers because they are more careful. Their thin fingers can easily remove the twin leaves and new shoots from the plant, which are the parts used for processing tea. The pickers carry large baskets into which they throw their pickings. A skilled worker can harvest between 9 to 14 kilogrammes of tea leaves a day. Usually new shoots can be picked from the plants about every ten or fifteen days. Processing tea shoots into the familiar dry tea leaves requires great care and skill. There are various methods of processing depending on the type of tea required. For black tea, the young green leaves are first spread out on shelves to dry. This process removes much of its water and the leaves become soft. After this, the leaves are passed through heavy rollers. This operation will press the leaves for juices which give the tea both its colour and taste. Then the leaves are spread out on floors and left to ferment under wet conditions. Fermentation develops the rich taste of black tea. The fermented leaves are then dried with a hotair blower until they become rolledup black leaves. The final step is to sort and grade them before the black tea is ready for sale to countries all over the world. What's the writer's purpose in writing the passage?
Choices:
A. To introduce various methods of tea processing.
B. To persuade readers to buy tea from Sri Lanka.
C. To tell a story that had happened in the tea gardens.
D. To inform readers of tea growing, picking and processing. | D |

Money spent on advertising is money spent as well as any I know of. It serves directly to assist a rapid distribution of goods at reasonable prices, thereby establishing a firm home market and so making it possible to provide for export at competitive prices. By drawing attention to new ideas it helps enormously to raise standards of living. By helping to increase demand it ensures an increased need for labor, and is therefore an effective way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television license would need to be doubled, and travel by bus or tube would cost 20 per cent more. And perhaps most important of all, advertising provides a guarantee of reasonable value in the products and services you buy. Apart from the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for mercifully the public has the good sense not to buy the inferior article more than once. If you see an article consistently advertised, it is the surest proof I know that the article does what is claimed for it, and that it represents good value. By the first sentence of the passage, the author means that _ .
Choices:
A. he is fairly familiar with the cost of advertising
B. everybody knows well that advertising is money consuming
C. advertising costs money like everything else
D. it is worthwhile to spend money on advertising | D |

Scientists have devised a way to determine roughly where a person has lived using a strand ( ) of hair, a technique that could help track the movements of criminal suspects or unidentified murder victims. The method relies on measuring how chemical variations in drinking water show up in people's hair. "You're what you eat and drink, and that's recorded in your hair," said Thure Cerling, a geologist at the University of Utah. While U.S. diet is ly identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move. Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also present as heavier isotopes ( ). The heaviest rain falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months. Cerling's team collected tap water samples from 600 cities and constructed a map of the regional difference. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad region roughly corresponding to the movement of rain systems. "It's not good for pinpointing ( )," Cerling said. "It's good for eliminating many possibilities." Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake. The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair. When Park heard about the research, he gave the hair samples to the researches. Chemical testing showed that over the two years before her death, she moved about every two months. She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming. "It's still a substantial area," Park said, "But it narrows its way down for me." What is the scientists' new discovery?
Choices:
A. One's hair growth has to do with the amount of water and drink.
B. A person's hair may show where they have lived.
C. Hair analysis accurately identifies criminal suspects.
D. The chemical composition of hair varies from person to person. | B |

Parkour is a new sport that is developing quickly in the world. The aim of parkour is to jump, climb or run over any all stair, or fence on your path easily. Usually, it is done in a city environment. Practicers take very wall or roof as their training place. If you have seen the beginning of the James Bond movie Casino Royale, then you have seen an excellent example of parkour. David Belle, a young Frenchman, developed parkour in the 1990s. His father's experiences as a fireman as well as an acrobat influenced him a lot. His childhood friend, Sebastien Foucan, is the actor in the movie Casino Royale with his parkour performance. Foucan is thought to have developed free-running, which is a more artistic and skillful type of parkour. David belle traveled to India and said one way he trained was by watching a physical one. The aim is to become so skillful, and it is almost unnecessary for you to think about the different actions in running through a path full of barriers . Parkour is not exactly a sport. It is not developed fro competition. It is more about learning to control mind and body in difficult situations. There are many basic movements in parkour. One example is where practicers swing through the narrow space between two bars while keeping their body level with the ground. This is called the underbar. Other movements are the tic-tac and the kong vault jump. Skillful practicers seem to get out of control of gravity. The popularity has spread largely because of parkour videos and organizations on the Internet. And if you search on the Web, you will find parkour groups performing their skills near you. People learn about parkour mainly for _ .
Choices:
A. the newspaper
B. the Internet
C. the radio
D. TV | B |

mmlu | Question:
A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to evade policemen after a bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into the home of Mary Parnell. Police say he didn't touch Parnell but that she died after suffering a heart attack that was caused by terror. Can the guy be held responsible for the woman's death? Prosecutors said that he can under the state's murder rule, which allows someone to be charged with murder if he or she causes another person's death while committing or fleeing from a severe crime like robbery--even if he or she doesn't kill someone on purpose. But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women's Hospital in Boston. Absolutely, no question about it. The body has a natural protective method called the fight-or-flight response , which was originally described by Walter Cannon,the chairman of Harvard University's physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the autonomic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to primitive humans. However, in the modern world there is obvious decline of the fight-or-flight response. The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is toxic in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death. Kidney failure, liver failure, those things don't kill you suddenly. By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in intercourse or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, "I can die now", and then he dropped dead. For about seven days after the 9/11 terrorist attacks on the World Trade Center and Pentagon there was an increase of sudden cardiac death among New Yorkers. What activity can we infer is less likely to damage the organs?
Choices:
A. Winning a big lottery.
B. Missing a dead family.
C. Watching a horror movie.
D. Listening to a sweet song. | D |
mmlu | Question:
Greenwich is on the River, five miles from the middle of London, and its history is two thousand years old. The first English people were fishermen there, and they named the place Greenwich, meaning "green village". Later the English kings and queens lived at Greenwich in their beautiful places. The name of the earliest palace was Placentia. Its windows were made of glass--the first in England. But trouble was coming to Greenwich. In 1649, a war started in England and for eleven years there was no king. The men who had worked for him at Placentia decided to live in the place themselves. They sold all its beautiful things, and bought small pieces of the palace garden with money. Finally, the war ended and King Charles II came back. But Placentia was falling down. So King Charles built a new and bigger palace, which is now open to the public. At this time, Charles was worried about losing so many of its ships at sea because their sailors did not know how to tell exactly where they were. So in 1675, Charles made John Flamsteed, the first astronomer in England, try to find the answer. Flamsteed worked in a new building on the high ground in Greenwich Park. From it with a telescope which he made himself, Flamsteed could look all round the sky. And he did, night after night, for twenty years. Carrying on Flamsteed's work a hundred years later, an astronomer called Harrison finally made a clock which told the time at sea, and helped sailors to know where they were.You can see Harrison's clock, still working, in Greenwich's museum of the sea. Because of Flamsteed's work, every country in the world now tells its time by Greenwich time. Charles made John Flamsteed try to find _ .
Choices:
A. how to tell the time
B. hot to build ships
C. a way for sailors to tell their positions at sea
D. a place to set up a telescope | C |
mmlu | Question:
Most recently, it's very common in students who need a parent present for job interviews. Naturally, it's easy to blame the students in these situations, but the bigger problem is us. We--as parents--are so eager to protect our kids that we fail to realize that this in itself is harming them. As the mother of two young sons, I have to remind myself all the time that the biggest responsibility I have as a parent is to help them develop the skills needed to live in, to live without me. So, I'll let them fail. I'll let them fail because as long as they are safe and warm inside their comfort zones, they will never grow. And failure--along with loss, heartbreak, disappointment, etc.--will be part of growth for them. Call me the anti-tiger mom, but leaving them alone is my way of helping them become equipped to fit in this world as we know it today. From terrorism and seemingly endless natural disasters, to our national debt and beyond, if we expect the next generation to stand up to the very real problems of our time, we need to stop feeding them and start teaching them how to fish. My children are faced with hard situations in their own life almost each day, but they try to negotiate everything now. It's a small price to help them learn a skill they'll use for the rest of their lives, including when I don't come with them on job interviews. The author believes experiencing failure in life can make kids _ .
Choices:
A. become healthier than other kids
B. grow in this challenging world
C. develop all social skills
D. escape from natural disasters | B |
