Question:
Sharing cars to work is not unusual.But what about sharing time to raise children together? In Ningbo city of Zhejiang province in East China, young mothers in the same neighborhood pool their children together, and share the responsibility of being parents. Spending every day together, but not families - in this coastal city of East China, three mothers are trying a new way of raising their kids, by pooling them together. Among the mothers are both office workers and housewives.They say they do so not just because of the tight schedule. Jiujiu's mother said, "By kids pooling, we mean to create an opportunity for the kids to spend time together so that we can observe our kids, learn more about them.And then we can discuss how to better bring them up." The three families have been doing so for two years, in school days and holidays.Their children have grown used to each other's company, Chichi's mother said, "My son was a bit shy.We've been talking him to be more active, but he hardly changed.After joining the kids pool, suddenly we found him willing to communicate with others now.When we are not there, he has to rely on himself to get along with his pals." Generally, mothers speak highly about the pooling.The mothers describe the pooling as bringing the running water into a closed pond.It opens a window to a different world for both kids and parents.But there are moments when opinions differ.Xiaoxiao's mother said, "Sex education for example.Kids will be curious about it when they reach a certain age.Personally I want to talk with my child about it, frankly and sincerely.But the other two moms think it better not to bring it up." Xiaoxiao's mother says her solution is to share some parenting guidebooks with other mothers and let them make the decision. The headmaster of the kindergarten believes such pooling activities test not only children, but also the parents.Jin Hongqing, kindergarten headmaster said, "Parents need to be tolerant and patient.They shouldn't play the blame game when kids fight with each other.It's better to let the kids solve the issue by themselves.What they can do as parents is to communicate." Why is sex education mentioned in the passage?
Choices:
A. To show sometimes mothers have different opinions.
B. To suggest children are sometimes curious about it.
C. To explain sex education is not suitable for children.
D. To indicate mothers think highly of kids pooling.

Question:
Oscar-winning actress Joan Fontaine, who rose to fame during Hollywood's golden age as the star of several Alfred Hitch.cock classics, died from natural causes at her home in Carmel, northern California on December 16, 2013 aged 96, US media reports said. Born in Japan to British parents, Fontaine moved in 1919 to California, where she and her elder sister -screen idol Olivia de Havilland-were to shape successful movie careers.Fontaine and de Havilland remain the only sisters to have won lead actress honours at the Academy Awards.Yet the two sisters also had an uneasy relationship, with Fontaine recording a bitter competition in her own account "No Bed of Roses ". Fontaine began her acting career in her late teens with Largely less important roles on the stage and later in mostly B-movies in the 1930s. It was not before famous British film director Hitchcock spotted her a decade later that her career took off. Greatly surprised by her expressive looks, the suspense master cast Fontaine in his first US film, a 1940 adaptation of the Daphne du Maurier novel "Rebecca". She received an Academy Award nomination for her performance as a troubled wife. A year later, Fontaine finally won the long-sought golden figure, for her role as leading lady in "Suspicion" opposite Cary Grant, becoming the first and only actress to earn the title for a Hitchock film. Although her sister, Olivia de Havilland, preceded her in gaining Hollywood fame, Fontaine was the first of the sisters to win an Oscar, beating Olivia's nomination as best actress in Mitchell Leisen's "Hold Back the Dawn". The dislike ,between the sisters was felt at the Oscars ceremony."I froze. I stared across the table, where Olivia was sitting.'Get up there!' she whispered commandingly," Fontaine said."All the dislike we'd felt toward each other as children...all came rushing back in quickly changing pictures...I felt Olivia would spring across the table and seize me by the hair." Olivia did not win her first Oscar until 1946, for her role as the lover of a World War I pilot in Leisen's " To Each His Own". Fontaine later made it known that her. sister had slighted her as she attempted to offer congratulations."She took one look at me, ignored my hand, seized her Oscar and wheeled away," she said. The sisters were also reportedly competitors in love. Howard Hughes, a strange businessman who dated the elder de Havilland for a time, offered marriage to Fontaine several times."I married first, won the Oscar before Olivia did, and if I die first, she'll undoubtedly be extremely angry because I beat her to it!" Fontaine once joked. As her film career fruited in the 1950s, Fontaine turned to television and dinner theatre, and also appeared in several Broadway productions, including the Lion in Winter". Anything but the ordinary lady, Fontaine was also a licensed pilot, a champion balloonist, an accomplished golfer, a licensed .decoration designer and a first-class cook. Which of the following statements is true according to the passage?
Choices:
A. Olivia preceded Fontaine in getting married.
B. Olivia gamed Hollywood fame after Fontaine.
C. Fontaine won an Oscar before her sister Olivia,
D. Fontaine wanted to meet her death before Olivia.

Question:
As the nights get lounger, those who suffer from the winter blues will be planning ways to escape to the sunshine. But there may be a much simpler way of cheering yourself up... simply shining a bright light into your ear canal. Up to one in four Britons suffer from seasonal affective disorder, with seven per cent of the population having full-blown SAD. It is caused by the brain not receiving enough daylight which is needed to trigger serotonin , a hormone that regulates mood. Symptoms range from mild lethargy to depression and insomnia, but a cure might be in sight. Two clinical trials, run by Valkee - who make a device that can shine light into your ear - and the University of Oulu in Finland, have found that carefully targeted light can help prevent the condition. Juuso Nissila, Valkee's co-founder and chief scientist said: "We presented earlier that the human brain is sensitive to light". "These two clinical trials demonstrate that channeling bright light via ear canal into brain's photosensitive areas effectively prevents and treats seasonal affective disorder." The University of Oulu reported that in their first study, 92 per cent of the patients with seasonal affective disorder achieved full remission after a month of daily eight-to-12 minute doses of light from the Valkee. Time Takala, chief physician at the Oulu Deaconess Institute said: "These two trials show that bright light channeled into the brain via ear canal is an important future method to treat seasonal affective disorder." Valkee launched its bright light headset in August 2010. It is classed as a medical device under EU regulations. The device channels bright light direct to the brain via the ear canal to prevent and cure depression, mood swings and even circadian-rhythm disorders such as jet lag. It costs PS185 and looks like an iPod - only the earphones emit light rather than sound. How many Britons suffer from seasonal affective disorder?
Choices:
A. Approximately a quarter.
B. 7%.
C. More than one fourth.
D. 92%.

Question:
Some countries have a large number of earthquakes. Japan is one of them, while others do not have many, for example, there are few earthquakes in Britain. There is often a great noise during an earthquake. The ground vibrates .Houses fall down. Railways are broken, which causes trains to turn over. Sometimes thousands of people are killed in different ways. About 60,000 were killed in 1783 in the south of Italy. Some people say that earthquakes often happen near volcanoes , but it is not true. The centres of some earthquakes are under the sea. The bottom of the sea suddenly moves. The powerful forces inside the earth break the rocks. The coast is shaken and great waves appear. These waves travel long distances and rush over the land when they reach it, breaking down houses and other buildings. Sometimes they break more buildings than the earthquake itself. A terrible earthquake happened in Assam, India, in 1986.The land near Shillong suddenly moved 1.5 feet to one side, and then back again. It continued to act like this 20 times a minute.Few buildings could stand what was happening and the great stones flew four feet up into the air. What kind of building stays up best in an earthquake? The Americans carefully studied the results of the earthquake at San Francisco(1906) and believed it best for buildings to be made with concrete walls together by steel frames. Such are the buildings that can't burn or fall easily. Earthquakes often happen _ .

Question:
NBA commissioner David Stern was in Orlando on Thursday night, getting ready for Sunday's All-Star Game. Of course, all he could talk about was the only player anyone wants to talk about these days: New York Knicks guard Jeremy Lin. Hours before Lin took the court against the Heat, a few hundred miles South down I-95 in Miami, Stern told reporters that Lin's instant popularity hasn't ever been matched in sports history, not even by Sunday's biggest names, LeBron James or Kobe Bryant. The Associated Press had the details. "I haven't done a calculation, but it's fair to say that no player has created the interest and the craze in this short period of time, in any sport, that I'm aware of like Jeremy Lin has," Stern said Thursday. Lin, an undrafted guard from Harvard, has become the NBA's biggest story since coming off the Knicks' bench earlier this month to lead them to nine wins in 11 games heading into their matchup with Miami on Thursday night. With Lin's popularity in Asia as the league's first American-born player of Chinese or Taiwanese descent, and with the religious community because of his strong Christian faith, Stern says he's "never quite seen anything like" the attention on Lin. "It's fascinating," Stern said after the All-Star Jam Session opening ceremonies. The top five videos on NBA.com since Feb. 4, when Lin joined the circulation, are all Lin or Knicks related. Lin went from 190,000 followers on Sina, China's version of Twitter, on Feb. 2 to more than 1 million as of Feb. 16. Indeed, Lin's popularity is so _ that the NBA made a late list switch to ensure his participation in the Rising Stars Challenge on All-Star Saturday, a game that includes the NBA's best rookies and sophomores. Lin is in such high demand that all of the game's other participants will meet with the media following a team practice on Friday while Lin will have his own, separate press conference later in the night. This is Jeremy's world, folks. We're all just living in it. Even David Stern and the rest of the league's All-Stars, at least for the moment. The following statements about Jeremy Lin's instant popularity are true EXCEPT that _ .
Choices:
A. Jeremy Lin led New York Knicks to win all the recent games this month
B. David Stern said Lin was the only instant popular player in NBA's history

Question:
Doubt usually comes along when companies talk very proudly how socially responsible they are, but Nike's decision to publish its entire list of contract suppliers on the Internet is harder to ignore. Nike's move opens a new front in companies' efforts to face their critics. As Nike states in its latest corporate responsibility report, it is often hard to confirm exactly what is happening at about 800 factories that make its footwear and clothing under contract, many of which are remote. Nike is hoping other companies will publish their factory lists, too. Hannah Jones, Nike's vice - president for corporate responsibility, says Nike would like to see the best - run contract factories using their social position as suppliers to the big brands to try to get more work. Nike's approach moves corporate responsibility into its third age. The first age was corporate philanthropy - companies donating money to various community projects. The $170, 000,000 that Wal - Mart gave in charitable donations last year is a good example. Of course, some critics oppose even this form of corporate generosity , arguing that companies should concentrate on making profits, leaving it to shareholders to decide what charitable donations to make. Corporate responsibility's second age was reputation management and risk avoidance. Second - age corporate responsibility supporters believe agreement with the wider community can warn a company of future risks in advance. Nike is now trying to go a stage further. The company says it sees corporate responsibility as a way of improving its performance rather than just protecting its reputation. Factories which ensure that workers are registered for social - security benefits often become more productive as a result. Attention to one aspect of staff management often leads to improvement in others. If other companies publish supplier lists, they can together work out common standards, Nike says. At present, different companies have different standards, which make life difficult for the many factories that produce for more than one brand. If other companies published suppliers' locations, they could work out common standards and save money by relying on one another's checks. Which of the following can be described as "the first age of corporate responsibility"?
Choices:
A. Communicating with the public to avoid criticism.
B. Avoiding danger and developing their brands.
C. Publishing its entire list of contract suppliers.
D. Offering money to community groups.

Question:
Industrial pollution is not only a problem for the countries of Europe and North America but also an extremely serious problem in some developing countries. For these countries, economic growth is a very important aim. They want to introduce industries, and so they put few controls on the industries which cause pollution. Cubatao, an industrial town of 85 000 people in Brazil, is an example of the connection between industrial development and pollution. In 1954, Cubatao had no industry. Today it has more than twenty large factories, which produce many pollutants . The people of the town are suffering from the poisonous matter in their environment and the bad effects can be clearly seen. Birth shortcomings are extremely common. Among children and adults, lung problems are sometimes twelve times more common in Cubatao than in other places. It is true that Brazil, like many other countries, has laws against pollution, but these laws are not enforced strictly enough. It is cheaper for companies to take no notice of the laws and pay the fines than to buy the expensive equipment that will reduce the pollution. It is clear, therefore, that economic growth is more important to the government than to the health of the workers. However, the responsibility does not completely lie with the Brazilian government. The example of Cubatao shows that international companies are not acting in a responsible way either. A number of the factories in the town are owned by large companies from France, Italy, and the U. S. They are doing things in Brazil that they would not be able to do at home. If they caused the same amount of pollution at home, they would be severely punished or even put out of business. How is the health of the population of Cubatao?
Choices:
A. There are more heart diseases among people who live near chemical factories.
B. More people suffer from lung diseases because of poisonous matter.
C. Their health is affected by pollutants the same way as that of other Brazilians.
D. Babies there are found not as bright as those who live in other places.

Question:
Last summer I was lucky enough to participate in a volunteer adventure to Kenya, in association with Virgin Atlantic's Be the Change programme and children's charity, Free the Children. The moment I read the e-mail saying that I had been accepted into Free the Children's Virgin Atlantic scholarship trip to Kenya, I had no idea how much it was going to change my life. I thought the trip would be a great way to learn about life in one of the most rural areas of Kenya, but I never thought about how deeply I might be affected by this once-in-a-lifetime opportunity. When we entered the Masai Mara, the first thing that struck me was how unbelievably beautiful it was. As I looked closer to it, I realized there was something even more beautiful: the people. I have never been to a place where the saying "the people are what make the place" was more true. The way they wave at you excitedly as you drive past, shouting "Jambo, Jambo!" is something that I have never experienced. They are always smiling and welcoming and it made me realize that, if everyone were to act like this, the world would be a much happier place. The most amazing thing about the trip was that we weren't treated like tourists for one second. We were able to experience every little detail. We built foundations, carried ten litres of water... The one thing I will never forget is visiting Emorijoi Primary School. Let me describe it like this: As soon as you entered into the gate, you would hear someone shouting your name. Then you looked around and realized that it was the same little girl that you were playing football with the last time you visited. There are literally no words to explain how much I miss Kenya. It feels like there is a piece of string attaching me to everyone that I met there. They will stay with me forever and always be in my heart. Which word can best describe the author's feeling of the adventure?
Choices:
A. Calm
B. Unexpected
C. Upset
D. Threatened

Question:
Rhinos are big and can be dangerous. They are also shy and seldom seen. Once there were hundreds of rhino species, but today there are only five. One ancient rhino called Indricotherium was the largest land mammal that ever lived. It was 5m high at the shoulders, and 8.5m long-- twice the size of today's biggest elephant! The living rhinos are still big, averaging 2-3m long and weighing up to 3,600kg. To see all five species of living rhino you would need to do a bit of exploring. First you might visit Africa for a look at the white rhino and the black rhino. They live in Africa's dry woodlands and grasslands. Then you could head to India and Nepal for a look at the Indian rhino. It lives in the high grasslands near rivers, where you have to ride an elephant to find one. Finally you might travel to the rainforests on the islands of Indonesia to see the Sumatran and Javan rhinos. These are the smallest and rarest rhinos in the world and extremely difficult to find. Most rhinos are gentle and timid .They have a bad reputation for being very , but that may be partly because they get frightened easily. Also, they have poor eyesight. They rely on their strong sense of smell to tell them a stranger is approaching, but if the wind is blowing the wrong way, they may not know someone is there until it's too late. Rhinos can be found only in their habitats, which is why habitat destruction has caused rhino populations to decline. As they disappear from certain places, their absence leads to many changes to the landscape. For example, black rhinos in Africa only eat shrubs and small trees, pruning the plants and limiting their growth. Many other species benefit from this, and as rhinos disappear, so do many other animals sharing their habitat. Bushes and trees take over the land and force species like the antelope to leave in search of food. In a short time the whole habitat has changed. From the text we learn that _ .
Choices:
A. rhinos are all big and dangerous
B. rhino numbers have declined greatly
C. rhinos are twice as large as elephants
D. Indricotherium is the world's biggest living animal now

Question:
It was raining as I ran out of the church, eager to get home and play with the gifts Father Christmas sent me. Across the street was a gas station, which was closed for Christmas, but I noticed a family standing under the narrow overhang to keep dry. I wondered briefly why they were there but then forgot about them as I couldn't wait to see my gifts. Once I got home, there was hardly any time to enjoy my gifts. My grandparents were still waiting for us to have Christmas dinner together at their house. As we drove down the highway, I noticed that the family was still there. The closer we got to my grandparents' house, the slower the car went. Suddenly, my father U-turned and said, "I can't stand it!" "What?" asked my mother. "It's those people back there at the gas station, standing in the rain." When my father pulled into the station, I saw there were five of them: the parents and three children--two girls and a small boy. Then we learned that the family was waiting for the bus to Birmingham, where the man planned to find a job. "Well, that bus won't come along for several hours. Winborn's just a few miles away, and there is a shed with a cover there," my father advised. "I will run you up there." Then they climbed into our car,. My father looked back and asked the children if Father Christmas had found them. Three sad faces gave him his answer. "Well, Father Christmas said he was having trouble finding you, so he just left your toys at my house this morning. Let's go to get them first," my father said. All at once, the three children's faces lit up. When we arrived at our house, one girl spied a lovely doll, that little boy took a ball, and the other girl picked up something else. That was the Christmas when I learned the joy of making others happy. At the gas station the family might feel _ .

Question:
I ran into quite a few language problems while vacationing with my family last summer. The most embarrassing was when my Mom apologized to the people we were staying with because her "pants were dirty". They looked at her in amazement, not knowing how to react. You see, Mom had fallen over and gotten mud on her jeans. But in Britain, "pants" means underpants or knickers, not trousers as it does back home. Katie -- From America I went to stay with a friend on the west coast last summer. Her flat was on the first floor of a high-rise building so I got the lift up. Then I wandered round for ages looking for her flat but couldn't find it. Fed up and tired, I finally had to go out to find a phone box. She explained that her flat was on the first floor, which for me meant the ground floor. David -- From Britain When I asked for the "restroom" in a big department store, people kept directing me to a room with seats where I could sit and "rest". It took me years to get through to someone that I only wanted the toilet! Tom -- From America Last summer we went on a two-week family touring holiday, so Dad hired a car over the Internet. This was an old vehicle and there turned out to be lots of things wrong with it.

Question:
I had been rather proud of myself when my friends and family got the ticket,whether it was for speeding,parking or stop sign violations .It was something that happened to others. But last Friday I joined _ . I was asked to do a new project last week. On Friday morning on my way to work,I suddenly remembered that I had spent the past six weeks without considering that I had a week's vacation planned during that time. I was very disappointed with myself for not remembering it. The truth is that I was not paying enough attention to my driving and I did not come to a complete stop at the stop sign in front of a school. I was so distracted that I didn't even notice I had a policeman on my tail with his lights flashing. Finally I looked in my mirror and caught on. The policeman was rude and took my papers. Fortunately,I had everything up to date and since I had never had a ticket before,there was nothing for him to do but write me a ticket. While I was sitting there in the seat of "shame",I felt bad. If I had been that distracted and a child had run onto the road,perhaps I would have not reacted as well as I could have. It was a wake-up call. People at work asked me if I tried to talk my way out of it. Frankly,it never occurred to me. I felt guilty. Now I no longer have a clean driving record.

Question:
By far the most common difficulty in study is simple failure to get down to regular concentrated work . This difficulty is much greater for those who do not work to a plan and have no regular routine of study . Many students muddle along , doing a bit of this subject or that , as the mood takes them , or letting their set work pile up until the last possible moment . Few students work to a set timetable . They say that if they did work out a timetable for themselves they would not keep to it , or would have to change it frequently , since they can never predict from one day to the next what their activities will be . No doubt some students take much more kindly to a regular routine than others . There are many who shy away from a self-controlled weekly timetable , and dislike being tied down to a fixed program of work . Many able students state that they work in cycles . When they become interested in a topic they work on it attentively for three or four days at a time . On other days they avoid work completely . It has to be admitted that we do not fully understand the motivation to work . Most people over 25 years of age have become used to a work routine , and the majority of really productive workers set aside regular hours for the more important areas of their work . The " tough-minded " school of workers doesn't fully accept the idea that good work can only be done naturally , under the influence of inspiration . Those who believe that they need only work and study _ have a mistaken belief either in their own talent or in the value of " freedom " . Freedom from control and discipline leads to unhappiness rather than to " self-expression " or " personality development " .

Question:
Jean-Michael Lourdis was a promising young pianist. But when the young man played, it seemed to him, as if his hands were iron. He worried so much about his playing that he became oversensitive to the comments of his playing. Unfortunately, in those days, a critic was not considered a critic, unless he found something wrong. This attitude of the critics would often leave the young man ready to give up his dream and return home. He was invited to play in Helsinki. The rich, the famous, the leaders of State were all there. Jean-Michael had one of those days when everything went wrong. That night as he played, he felt as if it were the worst concert of his young life. The next day, in the newspapers, some of the comments were so unkind. The young musician was painful. That day, as he sat in his hotel room in total despair , there came a knocking at his door. He had a visitor.The famous Finnish composer Jean Sibelius had come by to congratulate the young pianist on his performance. Jean-Michael asked how he thought of that and began to quote some of the newspaper critics. " Hands of iron. No imagination. Little skill. No joy. Don't you hear what they say?" he asked. Jean Sibelius looked at young Jean-Michael and said, "Remember, son, there is no city in the world where they have erected a statue for a critic." Jean Sibelius came to visit the young musician because _ .
Choices:
A. he wanted to tell the young man the critics were right

Question:
A blind boy sat on the steps of a building with a hat by his feet. He held up a sign which said, "I am blind, please help." There were only a few coins in the hat. A man was walking by. He took a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words. He put the sign back so that everyone who walked by would see the new words. Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy heard his footsteps and asked, "Were you the one who changed my sign this morning? What did you write?" The man said, "I only wrote the truth. I said what you said but in a different way." What he had written was, " Today is a beautiful day but I cannot see it." Do you think the first sign and the second sign were saying the same thing? Of course, both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the beauty of the day, but the boy could not enjoy it because he was blind. The first sign simply said the boy was blind. The second sign told people they were so lucky that they were not blind. What can we learn from this passage?
Choices:
A. It's helpful of us to help people in need.
B. There are many poor people in the world like the blind boy.
C. It's a good way to make money by holding a sign.
D. We should learn to speak to others in a suitable way.

Question:
Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people's depression , physical activity, and life satisfaction. In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner. "I talk to him all the time, and he responds to my voice," says a seventy-year-old lady. "When I'm watching TV, he'll stay in my arms until he wants down. He has his own mind." The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog _ exercise and feeding concerns. "At the beginning, it was believed that no one would relate(......) to the robotic dog, because it was metal and not furry." Beck says. "Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters' blood pressure, oxygen levels or heart rhythms . AIBOs may even one day have games that can help stimulate older people's minds." In the research, the old people are asked to _ .
Choices:
A. note the activities of AIBOs
B. keep AIBOs at home for 12 weeks
C. record their feelings and activity
D. study the collected information

Question:
In the more and more competitive service industry,it is no longer enough to promise customer satisfaction.Today,customer "delight" is what companies are trying to achieve in order to keep and increase market share. It is accepted in the marketing industry,and confirmed by a number of researches,that customers receiving good service will promote business by telling up to 12 other people;those treated badly will tell their tales of woe to up to 20 people.Interestingly,80 percent of people who feel their complaints are handled fairly will stay loyal. New challenges for customer care have come when people can obtain goods and services through telephone call centers and the Internet.For example,many companies now have to invest a lot of money in information technology and staff training in order to cope with the "phone rage"--caused by delays in answering calls,being cut off in mid-conversation or left waiting for long periods. "Many people do not like talking to machines,"says Dr.Storey,Senior Lecturer in Marketing at City University Business School."Banks,for example,encourage staff at call centers to use customer data to establish instant and good relationship with them.The aim is to make the customer feel they know you and that you can trust them--the sort of comfortable feelings people have during face-to-face chats with their local branch manager." Recommended ways of creating customer delight include:under-promising and over-delivering (saying that a repair will be carried out within five hours,but getting it done within two );replacing a faulty product immediately;throwing in a gift voucher as an unexpected "thank you" to regular customers;and always returning calls,even when they are complaints. Aiming for customer delight is all very well,but if services do not reach the high level promised,disappointment or worse will be the result.This can be eased by offering an apology and an explanation of why the service did not meet usual standards with empathy (for example,"I know how you must feel"),and possible solutions (replacement,compensation or whatever fairness suggests best meets the case). Airlines face some of the toughest challenges over customer care.Fierce competition has convinced them that delighting passengers is an important marketing tool,while there is great potential for customer anger over delays caused by weather,unclaimed luggage and technical problems. For British Airways staff,a winning telephone style is considered vital in handling the large volume of calls about bookings and flight times.They are trained to answer quickly,with their name,job title and a "we are here to help" attitude.The company has invested heavily in information technology to make sure that infomation is available instantly on screen. British Airways also says its customer care policies are applied within the company and staff are taught to regard each other as customers requiring the highest standards of service. Customer care is obviously here to stay and it would be a foolish company that used slogans such as "we do as we please".On the other hand,the more customers are promised,the greater the risk of disappointment. Customer delight is important for airlines because .
Choices:
A. their telephone style remains unchanged
B. they are more likely to meet with complaints
C. the services cost them a lot of money
D. the policies can be applied to their staff

Question:
My grandfather was a teacher. He was the headmaster of a school for boys between thirteen and eighteen. I know that he was a kind and gentle man at heart, because when I was young, he gave me presents, and seated me on his knee, and told me stories. But I believe the boys at his school were afraid of him. At school, when he walked into a room full of noisy boys, there was silence at once. When he looked at a boy with a certain look in his eyes, the boy went red in the face, and looked down at his shoes. If a boy brought him poor, careless work that was not the best the boy could do, my grandfather would pick up the boy's book and throw it across the room, shouting, "Do it all again, and bring it back to me in the morning!" If the boy was late, or if he forgot to bring the work, he had to do it again, and again, and yet again. My grandfather never forgot. He was a very different man at school from the man I saw day by day in his own home. This passage is mainly about _ .

Question:
If you can see the magic in a fairytale, you can face the future." --Danielle Steel Who have not read fairytales? We all have had the experience of reveling in the beauty and innocence of fairytales. May it be Cinderella or Sleeping Beauty... fairytale is a word which cannot be new to us. But have you ever traveled ages back to the earliest of times and uncovered the fascinating facts about these stories? Well, if not, then here are some mystical finds I discovered when I undertook this journey. A fairytale or fairy story is a fictional tale that usually features folkloric characters (such as fairies, talking animals). A fairytale often stars transformed princes, princesses, animals, as in "fairytale ending" where the humble but heroic princes defeat the wicked enemies or as in "fairytale romance" where after much ado the beautiful princesses marry their Prince Charming. One distinct feature of fairytales is that, they take place "once upon a time". The history of the fairytale is particularly difficult to trace. The oral tradition of the fairytale came long before the written page. The oldest known fairytales stem from ancient Egypt around 1,300 B.C and now, after traveling through various periods of time, they have grown and matured in various aspects and have become the most popular genre of stories for young children. The most famous authors of fairytales are the Grimm Brothers whose works include Cinderella, Rapunzel, Sleeping Beauty, Snow White and the Seven Dwarfs and many more; The Grimm Brothers collected their tales from farmers and edited them to suit their audience. But whatever may the form be, fairytales are after all fairytales! G. K. Chesterton said, "Fairytales do not tell children the dragons exist; they tell the dragons can be killed." This quote has great weight. Every child believes in fairies, dragons, etc. They do not need fairytales to tell them that. Instead fairytales tell that good always succeed over evil. So fairytales are necessary for young minds. Fairytales are narrated to children when they are young. This is very essential indeed, for if in the beginning of our lives our minds are touched by the beauty, innocence and the morals in these tales, we will be able to trace the optimistic side of happenings. The fairies are like our wildest dreams, which seem unreachable but we can make them plausible . What does the writer think about the fairytale?
Choices:
A. He believes that we can make fairytale come ture.
B. He thinks the fairytale makes no difference to our lives.
C. He feels doubtful of the fairytale.
D. He thinks the fairytale is unreachable.

Question:
As a foreigner,I don' t know the situation in the US well. Seeing all kinds of recent shooting incidents,I think it should be controlled more strictly than now. Somebody said that the person who has it in mind to kill another can do it without a gun,so the causes of murders are not guns but the trend of despising life in the US. And they also insist that there is no clear evidence that the increasing number of murders is connected with possession of guns,so the personal rights should not be restricted by the reason that there is not enough evidence. Several months ago,I agreed with that partly. But as we know,the private groups like NRA have used the public opinion and persuaded the government to protect their profit. Other weapons such as knives,razors ,bats are made for their own usage. But guns are made for only one reason--to kill someone. Of course,there are people who have guns to protect themselves from the criminals. But crime is getting more cruel and severe nowadays,so actually even if someone has a gun,it is impossible to guard himself completely. As a substitute ,I think,if the possession of guns is controlled more strictly,people can live safer lives than now. There are other reasons to oppose the gun control (e.g.the possession of guns is historical inheritance and represents that people's resistance will be against tyrannical government),but none of them can justify and explain today's serious situation in the US. The writer's purpose is to give his opinion about _ .

Question:
Teenager Jake Deham was skiing with his family in the US when he fell over and lost one of his skis. His family didn't know that he had a problem. They kept on skiing. When they got to the foot of the mountain, there was no sign of Jake. Jake couldn't find his ski anywhere. In the end, he decided to take off his other ski and walk down the mountain. But he couldn't work out the right way to go. It was now getting dark and he was a long way from any place of safety. He knew that he might die that night in the cold temperatures. But Jake kept calm. At home, Jake watched a lot of programmes about living in difficult situations. He remembered the advice from these programmes and knew that he should build a hole in the snow. He made a hole so the wind couldn't blow into it. Outside his hole, the temperature fell to a dangerous -15degC that night, but inside it Jake was safe from the cold. After the long evening passed, Jake began to think his way out. He had to get down the mountain. The TV programmes always said, "If you are lost, you should find someone else's tracks through the snow and follow them." "I wanted to live my life." remembered Jake, "So I got up and I found some ski tracks and I followed those." He walked and walked and finally saw lights... His mum was very happy when she heard her son was saved. Amazingly, Jake didn't even have to go to hospital. He got through the terrible experience without any injuries. So, the next time someone says that watching TV is a waste of time, think of Jake. Sometimes TV can save your life! . What can we learn from the story?

A. It is dangerous for us to travel alone.
B. Keep calm when facing difficulties.

Fire Station No.6 in Livermore,California,houses a celebrity--a 107-year-old light bulb that has been on for over a million hours,earning the title of the"World's longest continuously burning bulb"by Ripley's Believe It Or Not!The bulb also holds the Guinness World Record. Nobody knows why this bulb has stayed alive for so many years.Most people believe that it is due to two reasons--it has almost never been turned off and it is really well made.Its perfect seal lets no air in.keeping its carbon filament from burning out. The bulb was first installed at the fire department hose cart house on L Street in 1901.In 1903 it was moved to the new Station 1 on First and McLeod,and survived the renovation of the Firehouse in 1937.when it was off for about a week.The last time the bulb was switched off was in July l976,when it was moved to Fire Station No.6.Thousands of people watched as the electrician tried to re-attach the bulb at its new location.At first nothing happened and people thought the bulb had finally died.However,a slight touch of its switch and then,the bulb came on and has been on since.Nobody at the station dares to touch it,even to clean it. A local reporter first discovered the bulb's significance in 1972.He recommended his readers to go visit it if they ever went to Livermore.All of a sudden thousands of people came to Fire Station No.6 and the bulb became famous. Needless to say,the bulb is now a big source of pride and joy for the city of Livermore.So when some folks offered to buy it,the answer from the city was"NO!"

A few days before this current graduation, while working on final grades, I found a note a student had slipped in with her homework.She thanked me for being her teacher and said the things she had learned in my class--not about math, but about life--would be things she would remember long after the math skills had faded away.As I finished reading, I remembered why I had become a teacher.

Question:
The 87thAcademy Award nominations were announced on Jan 15, and The Grand Budapest Hotel stood out as a favorite with nine nominations, including Best Picture. Check out some other Best Picture nominees to see if you missed any of last year's top Hollywood films. The Imitation Game This historical thriller is about British computer scientist, Alan Turing (Benedict Cumberbatch), the father of artificial intelligence. At the start of World War II, Turing was asked to join a select team of mathematical geniuses to decode the system the Nazis used to send military messages. Besides the actual breaking of the code, Cumberbatch's portrayal of Turing's personality, a mixture of decency and shyness, is also a highlight of the movie. Birdman This dark comedy film is about how Riggan Thomson, a faded star once famous for his superhero roles, struggles to regain fame. American actor Michael Keaton, 63, who has a similar experience to Thomson's, plays the leading role. Selma A stellar cast including talk show queen Oprah Winfrey may be one reason to see Selma. But that the film focuses on Martin Luther King Jr.'s struggle for civil rights also makes it worth viewing. Based on the 1965 Selma to Montgomery voting rights marches, the film is a chronicle of King's (David Oyelowo) campaign for political rights for African-American people. The Theory of Everything We know English theoretical physicist Stephen Hawking for his significant scientific discoveries, especially his black hole theories. This biographical film reveals the scientist's (played by Eddie Redmayne) secret romantic relationship with Jane Hawking (Felicity Jones), whom he meets and falls in love with at Cambridge and who later becomes his first wife. Boyhood American Director Richard Linklater did an experiment in this film, using the same cast for 12 years to record a boy's growth. In two and a half hours, we see Mason, a Texas boy from a divorced family, grow from 6-year-old boy to a freshman in college. What is Boyhood mainly about?
Choices:
A. How Richard Linklater did his decade-long experiment.
B. The wonderful life of Mason.
C. The growth of a young boy.

Question:
A house of cards? Sounds unbelievable, doesn't it? Not if the architect is 31-year-old Bryan Berg. He's made a career out of building fantastic card houses, stadiums, capitols, castles -- and the world's tallest card tower. How does he do it? Bryan's structures are amazing because they are made entirely of perfectly balanced, freestanding playing cards. He never uses glue, tape, or anything else to hold the cards together. Nor does he fold the cards. He's discovered another way to make a strong house of cards, using a trick from nature. To make plants strong, nature builds them with cells that have tough walls. Rows and rows of these cells form a grid that helps leaves and stems keep their shape. Bees use the same kind of repeating pattern to create strong honeycombs, where they live and store honey. Bryan designs similar grids, using cards to create a repeating pattern of cells. He begins with a single cell made by balancing four cards against one another to form a box. Then he repeats the cell over and over, expanding outward to form the grid, which makes a good foundation for a strong card structure. The larger the grid, the more weight it can carry. Sometimes Bryan uses several cards, instead of just one, to construct the cell walls, making the grid even stronger. The trick, he tells kids when he speaks in classrooms, is to place your cards as tightly together as possible when laying out your grid, making sure the cards are not leaning at all. After building this solid base, Bryan lays cards across the top to make the floor for the next "story" of the building. He may add towers, columns, steeples, or domes. Using the principle of repeating cells, Bryan builds structures of amazing strength. In the Cards Not surprisingly, Bryan has always been interested in building things. Growing up on a "big, old farm" in rural Iowa, he had plenty of room to play. "We were in the middle of nowhere," Bryan remembers, "with lots of space to do whatever we wanted. I was always making something, using things like sticks or bales of hay." Bryan's grandfather taught him how to stack cards. Bryan's two interests -- building and card stacking -- soon combined. But stacking in his family's farmhouse was challenging. "Our old house had wood floors that weren't all level," he reports. "And they weren't very firm. When people walked around, it was like 'earthquake action.' It was a challenge to build something that wouldn't fall down immediately." Bryan constructed tower after tower; he went through a lot of trial and error before he built anything taller than himself. When he placed a few decks of cards on top of his grid, he discovered how strong it was. Bryan's towers began to grow taller. How Tall Is Too Tall? Bryan's first Guinness World Record for the world's tallest card tower came in the spring of 1992, when he was in high school. Learning that the world record was 12 feet 10 inches, Bryan built a slim tower that topped out at 14 feet 6 inches. Done as a project for his geometry class, it took him 40 hours and 208 decks of cards. Since then he's gone on to win world records for even taller buildings. His latest winner measured 25 feet 3.5 inches and used about 2,400 decks of cards. _ Why don't these towers fall down? The key is in a good solid base, a repeating pattern of stories, and a tapering top. Bryan likes to point out how card buildings resemble real ones. They are built cell by cell, story by story. The separate parts make one strong whole. The heavier the building, the stronger and more stable it is. But the weight can't all be at the top. After spending so much time building something so cool, Bryan admits it's sometimes painful to see his structures destroyed. But he compares his work to the building of a sandcastle or an ice sculpture. "They wouldn't be as special if they were permanent," he points out. "My buildings are like snowdrifts, or clouds in the sky. They can't last forever. According to the article, which natural structure is a model for Bryan's card structures?

A. A sand dune.
B. A honeycomb.

Question:
I have a friend named John Roberts who owns a horse ranch in San Ysidro.The last time I was there he shared a story with me. "It is a story about a young man who was the son of an itinerant horse trainer. When he was a senior,he was asked to write a paper about what he wanted to be and do when he grew up." That night he wrote a seven-page paper describing his goal of someday owning a horse ranch. He wrote about his dream in great detail and he even drew a diagram of a 200-acre ranch, showing the location of all the buildings,the stables and the track. "The next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a note that read, 'See me after class.'" "The boy went to see the teacher after class and asked, 'Why did I receive an F?'" "The teacher said, 'This is an unrealistic dream for a young boy like you. You have no money. You come from an itinerant family. You have no resources. Owning a horse ranch requires a lot of money. You have to buy the land. You have to pay for the original breeding stock and later you'll have to pay large stud fees. There's no way you could ever do it.' Then the teacher added, 'If you will rewrite this paper with a more realistic goal, I will reconsider your grade.'" "The boy went home and asked his father what he should do. His father said, 'Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.'" "Finally,after sitting with it for a week, the boy turned in the same paper, making no changes at all. He stated, 'You can keep the F and I'll keep my dream.'" John continued, "I tell you this story because you are sitting in the middle of my 200-acre horse ranch. I still have that school paper framed over the fireplace." He added, "If I had changed my paper at that time, maybe we would not have the chance to be here talking about the dreams ." What can we learn from the article?
Choices:
A. Make decision by yourself.
B. Never give up dreams easily.
C. Praise makes a difference.
D. Success needs other's help.

Chances I really love my job because I enjoy working with small children and like the challenges and awards from the job. I also think my work is important. There was a time when I thought I would never have that sort of career . I wasn't an excellent student because I didn't do much schoolwork. In my final term I started thinking what I might do and found I didn't have much to offer. I just accepted that I wasn't the type to have a career.

We agreed that if I had to work extra hours one week, she'd give me time off the next. But unfortunately, it didn't often work out. I was getting extremely tired and fed up, because I had too many late nights and early morning with the children. One Sunday, I was in the park with the children, and met Megan who used to go to school with me. I told her about my situation. She suggested that I should do a course and get a qualification if I wanted to work with children. I didn't think I would be accepted because I didn't take many exams in school. She persuaded me to phone the local college and they were really helpful. My experience counted for a lot and I got on a parttime course. I had to leave my job with the family, and got work helping out at a kindergarten. Now I've got a fulltime job there. I shall always be thankful to Megan.

Question:
One Canada, Two Languages Canada is one of the few nations in the world to have two official languages: English and French. There are 10 provinces in the country but only one of these--Quebec is known as "French Canada". This is because it was founded by French explorers while British adventurers discovered the rest. Canada left the British empire in 1867 to become an independent country, and English and French have been recognized as the official languages ever since. Most people speak English as their first language and the two national television networks broadcast in English throughout the country. Apart from in Quebec and a few places on the east coast, French television is very rare. The same goes for traffic signs and menus. For example, outside of Quebec, there are only a few places where you'll see traffic signs in French. In restaurants, it's almost impossible to find French on the menu unless you are in the heartland of French Canada. However, all products sold in Canada must, by law, have labels and instructions in both languages. In Canada's English speaking provinces, official bilingualism means that students can choose to complete a special French language course. Under this programme, they are taught most of their subjects in French. If a student begins the course in kindergarten or Grade One, it is likely that all their lessons will be in French. However, if they start at junior high school,25 per cent of the teaching will continue to be in English. Which of the following sentences is right?
Choices:
A. English is the only official language, though French is also spoken there.
B. The two national television networks broadcast both in English and French.
C. All products sold in Canada must, by law, have labels and instructions in both English and French.
D. The lessons in kindergarten or Grade One are likely to be only in English.

Question:
You probably know that frogs hop ( ). But did you know that there's a small frog in the Pacific Northwest that bellyflops ? It's called a tailed frog. Dr.Rick Essner, who has been studying tailed frogs for the past few years, says, " I've looked at thousands of jumps and have never seen them land on their feet like other frogs." Most of the time, tailed frogs land on their stomachs and then bring their back legs in to prepare for another jump. Essner forst noticed these frogs because of the way they swim. Other frogs kick both of their back legs at the same time. But when a tailed frog swims, it pushes first with one leg and then the other. To try to find out why tailed frogs bellyflop, Essner and other scientists collected and filmed different kinds of frogs. They found that all of the frogs start their jumps the same way: they hold out their legs. The change comes in the landing. Tailed frogs can't move their back legs as quickly as other frogs do. Maybe they don't need to. Tailed frogs live around water and quickly jump into the water to escape danger. Early frogs developed around watery areas and could jump quickly into the water to escape danger. Scientists think those frogs blended in with (...) the green plants on the side of the rocky rivers, just like today's tailed frogs. "Iwould guess that other animals would have problems _ them, " explains Essner. When other animals find those early frogs, the frogs could jump into the river. They didn't need to continue hopping. Tailed frogs and other kinds of frogs went their own ways about 200 million years ago. Tailed frogs stayed by rivers. Other kinds of frogs moved to places where new hopping skills allowed them to survive. Why do tailed frogs bellyflop?
Choices:
A. They have never left the water to live .
B. They have trouble in holding out their legs
C. Their back legs can't catch up while jumping..
D. Their front legs develop better than the back ones.

Question:
Over the past decade, cheating--an act of academic dishonesty--has become more and more common. The latest statistics shows more than two thirds of high school students admitted cheating on an exam last year, and--even more surprising--often the best students cheat to get to the top of their class--and they don't think it is wrong. It's not a big deal. Everybody is doing it. It is a big deal! Cheating is basically wrong and must be punished. If students easily get away with it, they might be encouraged to do it again. They won't realize that this--in the broadest sense--is an attack on our society, which is based on values like honesty and fairness. The present spreading of cheating indicates a loss of those values and cannot be tolerated. An appropriate punishment for cheating incidents would make students aware of their misbehavior. If no one were punished for cheating, who would ever study for an exam? Tons of papers would be _ from websites, writing crib sheets would be more important than reviewing the subjects, and highly sophisticated cheating arts would be invented. Knowledge would only exist on the Internet and on cleverly created cheat sheets, but not in the minds of the students--a rather bad precondition to enrich our society wisely and intelligently. Students have to learn that they have to learn. Only doing what's right will bring them a feeling of pride and accomplishment and create self-confidence--the building blocks for a successful and satisfying life and a society that keeps its values. What is more surprising is that _ .

Question:
Most high schools have at least four sports they offer to their students. In many districts, there must be an equal amount of sports for boys and girls. Some schools even have sporting clubs. High school sports have been an important part of the high school curriculum for many years. However, not all parents fully realize the importance. Some children are not even allowed to participate in school sports, because of the cost, the time commitment , or the possibility of injury. The truth is that high school sports are more than just fun. They are great tools to help students learn about life. They can teach students teamwork, cooperation, and leadership, etc. Students can take these things into their everyday lives as well. When they build their confidence on the sporting field, students are also building confidence against the world. They will be able to work well with others in all other areas of their life. High school sports are also the perfect way to keep teens away from drugs and other dangerous behaviors. Coaches are great role models that can often encourage players to be well behaved. Some schools even have limits on GPAs (grade point average) for their athletes. If a student athlete's grades fall below a certain point, they cannot play. Students who love sports will do anything to play, including studying more. They will also be less likely to try drugs or break the law in any other manner. So, allow your children to participate in school sports. Get involved and make friends with the parents of the other students. The whole family can have a great time and learn about sports together. Which of the following is NOT used to support the idea that school sports help keep students away from some dangerous behaviors?
Choices:
A. Coaches have a positive effect on students.
B. Schools are strict with their students.
C. Students loving sports study more.
D. Parents can have a great time with their children.

Question:
We have entered a new age of embedded , intuitive computing in which our homes, cars, stores, farms, and factories have the ability to think, sense, understand, and respond to our needs. It's not science fiction, but the dawn of a new age. Most people might not realize it yet, but we are already feeling the impact of what's known as the third wave of computing. In small but significant ways it is helping us live healthier and more secure lives. If you drive a 2014 Mercedes Benz, for example, an "intelligent" system tries to keep you from hitting a pedestrian. A farmer in Nigeria relies on weather sensors that communicate with his mobile device. Forgot your medicine? A new pill bottle from AdhereTech reminds you through text or automatic phone messages that it's time to take a pill. Technology is being integrated into our natural behaviors, with real-time data connecting our physical and digital worlds. With this dramatic shift in our relationship to technology, companies can adapt their products and services. To understand how revolutionary the third wave is, we ought to consider how far we have come. The first wave began when companies started to manage their operations through mainframe computer systems over 50 years ago. Then computing got "personal" in the 1980s and the 1990s with the introduction of the PC (personal computer). For the most part, computing remained immobile and lacked contextual awareness. In computing's second wave, mobile computing and the smartphone took center stage. Billions of people, some of whom might not have had access to clean water, electricity, or even housing, were connected. Developers created applications and provided consumers with access to just about everything through their phone at the cost of a monthly data plan. As the third wave keeps developing, designers must meet the demands of consumers who want to experiment with new technology. Historically, designers have focused their attention on a product's form and function. While that still matters, of course, the definition of a meaningful user experience has expanded significantly and will continue to do so. Instead of creating a single product, designers will need to imagine a series of connected products and services that have awareness of each other and their surroundings. In the first wave of computing _ .
Choices:
A. companies' operations were reliable on computer systems
B. computing had awareness of people's needs in the context
C. people could have access to computing almost everywhere
D. it was possible for people to experience computing at home

Question:
Did you ever look up at the moon and think you saw a man's face there?When the moon is round and full,the shadows of the moon mountains and the lines of the moon valleys sometimes seem to show a giant nose and mouth and eyes. At least,some people think so. If there were a man on the moon -- instead of mountains and valleys that just look like the face of a man -- what would he be like? He would not be like anyone you know. He would not be like anyone anybody knows. If the man on the moon were bothered by too much heat or cold the way Earth people are,he could not stay on the moon. The moon becomes very,very hot. It becomes as hot as boiling water. And the moon becomes very,very cold. It becomes colder than ice. Whatever part of the moon the sun shines on is hot and bright. The rest of the moon is cold and dark. If the man on the moon had to breathe to stay alive,he couldn't live on the moon because there's no air there.(He'd have to carry an oxygen tank,as astronauts do.) There's no food on the moon,either. Nothing grows -- not even weeds. If the man on the moon liked to climb mountains,he would be very happy. There are many high places there,such as the raised land around the holes,or craters,of the moon. Some of these _ are as tall as Earth's highest mountains. But if the man on the moon liked to swim,he would be unhappy. There is no water on the moon -- just dust and rock. When you think of what it's like on the moon,you may wonder why it interests our scientists. One reason is that the moon is Earth's nearest neighbor -- it is the easiest place in space to get to. Going back and forth between the moon and Earth,astronauts will get a lot of practice in space travel. Things learned on moon trips will be of great help to astronauts who later take long,long trips to some of the planets. Scientists are also interested in the moon because it has no air. The air that surrounds Earth cuts down the view of the scientists who look at the stars through telescopes. A telescope on the moon would give them a clearer,closer view of the stars. What is the main idea of the passage?
Choices:
A. We can learn much from research on the moon.
B. There may be human beings on the moon.
C. If there were a man on the moon,there would be many similarities between the man on the moon and on the Earth.
D. A telescope on the moon would help scientists have a clearer,closer sight of the stars.

A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way. Security experts patrolled several streets in the City of London seeking evidence of wireless networks in operation. Of 124 that they identified, 83 were sending data without encrypting them. Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet. The data could include sensitive company documents containing valuable information. Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users. Most companies using wireless networking technology do not take even the simplest of measures to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated in order to give a minimum level of security, for example, by encrypting the data being passed over the network. Raymon Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem. People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls. Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in. Switching on the security that comes with the network technology should be automatic. Then there are other basic steps a company can take, says Mr. Kruck, such as changing the passwords on the network from the default setting. Companies can also install firewalls, which form a barrier between the internal network and the public Internet. They should also check their computer records regularly to spot any abnormal activity, which might betray the presence of a hacker. Whichof the following is NOT considered in the study?
Choices:
A. The number of computer hacking incidents.
B. The number of wireless computer networks identified.
C. The way in which data are sent and received.
D. The way in which data are hacked and stolen.

Question:
In every school there is a "top" crowd that sets the pace, while the others follow their lead. Let's say the top crowd decides that it is smart to wear bright red sweaters. Pretty soon everybody is wearing a bright red sweater. There is nothing wrong with that, except the fact that on some people bright red sweater is extremely unbecoming. The situation can even become dangerous, if the top crowd decides that it is smart to drink or to drive cars at seventy miles an hour. Then the people who follow the lead are endangering their lives. They are like the sheep being led to the butcher. Now, chances are that you have come across situations like these more than once in your life; chances are that one time or another you probably did something you knew to be wrong. You may have excused yourself by saying, "Gee, the crowd does it." Well, let the crowd do it, but don't do it yourself. Learn to say, "No." Develop your own standards and your own judgment. If you know the crowd is planning something you disagree to, have the courage to bow out mannerly. You'll have the satisfaction of standing on your own two feet. The author doesn't think it good wearing red sweaters if _ .

Question:
On any weekend throughout the year one can spend hours browsing through neighborhood flea markets.These are very popular for those who are in search of bargains and who have a keen eye for picking through what others have .They hunt and search for something they can reuse.Americans love secondhand merchandise which can be bought cheaply and restored to its original use.In many cases the condition and the quality are still good, though the style might be outdated. For some people searching through flea markets is a hobby which reaps rewards.They look for possible antiques among the items for sale or for old furniture which can be restored with a little care and used again.Many wise collectors often find rare items worth much more than their bargained price.Since prices are usually not fixed, if one is persistent a bargain can easily be struck.The owner may be selling a rare collectable and may not even be aware of its value.One of the great pleasures of shopping at such markets is the chance to bargain with the shop owner and settle for a price which one can afford and is willing to pay. Perhaps even more enjoyable than flea markets are the weekend outdoor garage sales which have now become very much a part of American culture.These are held usually in the spring and fall when the weather is still good.Usually a homeowner, having decided that he would like to clear his residence of accumulated items which are no longer useful to him, advertises in a local paper that he is holding a garage sale.More than likely the goods on display are in good condition and great buys can be found if one has the time and patience to search carefully.The home owner places items for sale on display along the driveway leading to his garage or on his front lawn and waits for people to look at what he has to sell.Old magazines, books, paintings, bicycles, ice-skates, items of clothing and electrical appliances of every sort appear on a regular basis.If the owner is in a position where he must sell his home or plans to move soon, then he may be forced to practically give things away at a price far below their true worth. What do we know about the garage sale?
Choices:
A. It is only held in the spring of the year.
B. The goods on display are totally useless.
C. Garage sales are popular with Americans.
D. All the goods are selling far below their real value.

Question:
Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some extent our intelligence is given to us at birth, and no amount of special education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person's intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways. It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. Thus if we take two unrelated people _ from population, it is likely that their degree of intelligence will be completely different. If on the other hand we take two identical twins, they will very probably be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth. Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degrees of intelligence. It is suggested in this passage that _ .
Choices:
A. close relation usually have similar intelligence
B. unrelated people are not likely to have different intelligence
C. the closer the blood relationship between people, the more different they are likely to be in intelligence
D. people who live in close contact with each other are not likely to have similar degrees of intelligence

Question:
"It was all his own idea, " says Pat Peters, the 38-year-old wife of Palo Alto, California high school . Bob had just drawn up a "motherhood contract" ----- a document stating that for 70 days this summer he would take over the care and feeding of the couple's four children, plus all household chores . Although he didn't even know how to make coffee when he signed, he was quite confident.(He thought the experience would make a nice book.) After 40 of the 70 days, he was ready to give up. "I was beaten down, completely humbled, " admits Peters. Three weeks later he spoke to the local press (also part of the bargain), stating, "Not only is motherhood a difficult task, not only is it never-ending, it is an impossible job for any normal human being." Bob and Pat were high school sweethearts. After they were married in 1960, she worked as a secretary to help put him through university. Since then Bob has been the football and wrestling coach at Palo Alto's Cubberley High while Pat raised the kids. Then two years ago Pat went back to work as a secretary at Cubberley. "I had been around children so much," she sighs , "I couldn't talk to a grown-up." She continued to run the household, however----- until Bob signed the contract, whereupon she decided to relax and enjoy it. Although Peters had consulted with his school's home economics teachers and the head of the cafeteria , his meals were sometimes a disaster. "I tried to slip the butter I'd forgotten under the eggs after they were frying, " he says. For the last three weeks, the family ate out a lot--sometimes having Macdonald's hamburgers for lunch and dinner. As for housekeeping, a home economics teacher had told Bob that a room always looks clean if the bed is made. "I found an easier way-----I shut the doors, " he says. Soon the kids were wearing the same clothes for a week. "I made them wear their shirts inside out, and when we went to pick up Pat at work they turned them right side out so they would look clean." Now that Bob has publicly admitted he was wrong, he is routinely sharing the child-raising and household tasks with Pat. The tentative title of his book about the summer is taken from something he shouted at the kids one day. The couple signed the contract because _ .
Choices:
A. Pat complained a lot about her doing the housework all by herself
B. Bob loved taking care of children and wanted his wife to have a good rest
C. they agreed that husband and wife should share household tasks
D. Bob thought it easy to take care of the family and wanted the experience for a book

Question:
As he looks up at the Jade Dragon Mountain, Zhang Jinpeng basks in the sunshine on the roof-top of his youth hostel in Lijiang, a popular tourist destination in Yunnan province in Southwest China. He is content and excited at the same time, since the hostel, which he named after his best-seller A Decade of Backpacking, opened earlier this month. Published in 2010, Zhang's book was considered a milestone in Chinese travel writing. It sold more than 600,000 copies and triggered a wave of travel books by other Chinese writers who were born in the late 1970s and 1980s. Different from travel guides and traditional Chinese travel literature that mainly depict landscapes and scenery, these books by young travelers tell stories of their personal growth through traveling. In A Decade of Backpacking, Zhang recounts his travels around the world since 2001, after he graduated from Nan Kai University in Tianjin and decided to see the world. "At the time my book came out, there were few books that catered to young people's longing while traveling." Zhang's book ignited a Chinese craze for travel writing. Featuring different themes, travel writing became a popular genre. But most of the books have one thing in common: The travelers are mostly young people. The Late Gap Year (2009), written by Sun Dongchun, tells the story of a young man who gave up a white-collar job and started a three-month trip for a volunteer program in Southeast Asia. The trip turned into a year-long travel. What's more, he even found his Miss Right and got married by the end of the story. We Always Travel Hand in Hand, published in 2012, was written by a young couple. Their travel romance, complete with beautiful pictures, first went viral on a Chinese micro-blog. Song Zhenshao, counselor at the psychological counseling center of Beijing Normal University, says: "To step out of ordinary life is a deep desire associated with freedom in people's hearts, and the hustle and bustle of city life intensifies the desire." But as more similar travelogues hit the bookshelves, the average sales for new travel books have dropped. "The market for travel writing has become saturated ," says Li Shen, editor of several travel books at the Beijing-based China Civic Press. "We have been very cautious in accepting manuscripts from new travel writers. We don't publish them unless they have a very unique perspective or unusual experiences." Zhang Jinpeng, too, has been changing the direction in his writing. After A Decade of Backpacking, he published Why We Travel in 2012. His next book will be titled Don't Forget the Road Back Home. If new travel writers want to impress the editors, _ .

Question:
Flight Distance Any observant people have noticed that a wild animal will allow a man or other potential enemy to approach only up to a given distance before it escapes. "Flight distance" is the terms used for this interspecies spacing. As a general rule, there is a positive relationship between the size of an animal and its flight distance --- the larger the animal, the greater the distance it must keep between itself and the enemy. An antelope will escape when the enemy is as much as five hundred yards away. The wall lizard's flight distance, on the other hand, is about six feet. Flight is the basic means of survival for mobile creatures. Critical Distance Critical distance apparently is present wherever and whenever there is a flight reaction. "Critical distance" includes the narrow zone separating flight distance from attack distance. A lion in a zoo will flee from an approaching man until it meets a barrier that it cannot overcome. If the man continues the approach, he soon penetrates(,)the lion's critical distance, at which point the cornered lion turns back and begins slowly stalk the man. Social Distance Social animals need to stay in touch with each other. Loss of contact with the group can be fatal for a variety of reasons including exposure to enemies. Social distance is not simply the distance at which an animal will lose contact with his group --- that is, the distance at which it can no longer see, hear, or smell the group --- it is rather a psychological distance, one at which the animal apparently begins to feel anxious when it goes beyond its limits. We can think of it as a hidden band that contains the group. Social distance varies from species to species. It is quite short --- apparently only a few yards --- among some animals, and quite long among others. Social distance is not always rigidly fixed but is determined in part by the situation. When the young of apes and humans are mobile but not yet under control of the mother's voice, social distance may be the length of her reach. This is readily observed among baboons in a zoo. When the baby approaches a certain point, the mother reaches out to seize the end of its tail and pull it back to her. When added control is needed because of danger, social distance shortens. To show this in man, one has only to watch a family with a number of small children holding hands as they cross a busy street. Which of the following one can be the best title of the passage?
Choices:
A. Critical Distance
B. Spacing in Animals
C. Relationship Between Animals
D. Psychological Distance

Question:
"If there is one thing I'm sure about, it is that m a hundred years from now we will still be reading newspapers. It is not that newspapers are a necessity. Even now some people get most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation. The nature of what is news may change .What basically makes news is what affects our lives - the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though .It's already happening in areas that may directly affect our lives, like genetic engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do - as we develop a better understanding of how the brain operates and what our feelings really are. It's quite possible that in the next century newspapers will be transmitted electronically from Fleet Street and printed out in our own home. In fact ,I'm pretty sure how it will happen m the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read - sports and international news, etc. I think people have got it wrong when they talk about competition between the different media .They actually _ each other. Some people once foresaw that television would kill off newspapers, but that hasn't happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet. it's never really pleasant to read something just on a screen. What will probably be on in the newspaper made by yourself?
Choices:
A. Sports and international news.
B. A menu of important news.
C. The most Important news.
D. what you are interested in.
