It took courage to stand up at work. Now more and more people like to have a change and stand up when they are on something important. Standing up is popular. Medical researchers have found that people who stand at work tend to be much healthier than those who sit. In the last few years, many office supply companies have begun to sell the adjustable- height desk. These so- called " sit/ stand" models are equipped with an electric motor that lets them shift from chair height to person height at the push of a button. Unfortunately, they're regarded as specially furniture. Sit/ stand desks tend to be expensive, hard to find and not easy to test it in person. When you worked standing up, your mind was more excited and new ideas kept coming out. This is because when you're standing, you feel a bit _ from your desk. If you got stuck on a word or sentence as you wrote, you found yourself shaking your arms, bouncing on your feet or stepping away from the desk for a bit------ things you couldn't do in a chair. Often, standing up seemed to relax your mind enough for you to get over creative barriers. There's one other thing about standing for a long time; you tended to get hungrier than you do when you sit on a chair. That felt like confirmation of the stand-up advocates' belief that you burn more calories when you stand than when you sit. For this reason alone, I'm hoping that sit/ stand desks one day hit the mainstream, with mass- market furniture companies making many low- priced versions. We could all do with a bit more standing up. According to para.3, standing up while working _ .

Most children have heard their parents at one time or another yell "sit up straight!" or "don't slouch!" In the past, this was usually heard at the dinner table as children ate dinner. But these days, it is also heard around another activity-video games. Ten-year old Owaish Batliwala, from Mumbai, India, admits he spends three to four hours each day playing games on his tablet computer. His mother Mehzabin became concerned when her son started saying that his neck hurt. She said, "My son started having neck problems around June or July. The pain slowly spread to his hand and his back. He plays for hours on the iPad and mobile phone. This is what has caused the problem." Sadia Vanjara is a physical therapist. She says the number of young children with chronic pain in their necks, arms and shoulders is on the rise. Dr. Vanjara says the pain is not from aging, accidents or disease. It is from poor posture, or body position, while playing video games. "They are not aging, they haven't had an accident, their age is like, under 10, they are not complaining, the blood reports are fine, their x-rays are fine, their MRI's are fine, then where is the culprit ? And that is the very common thing that is happening amongst all children and that is smart phones and the gadgets ." This is a problem in many parts of the world. But there are more smartphone users in India than anywhere else in the world, except China. Networking equipment company Cisco estimates that the number of smartphone users in India will increase from 140 million today to 651 million by 2020. 19-year old student Nida Jameel says she feels pain in the finger which holds the weight of her smartphone most of the day. She says she uses her smartphone 24/7. This means 24 hours a day, seven days a week, or all the time. "As I use phone 24/7 (all day) like, so probably yeah, it was because of the phone, continuous usage and Snapchat, Whatsapp, more and more you know social media coming, so like phone is the center of everything." Dr. Vanjara says the best treatments for the pain are daily exercises. "And start stretching it in all the possible directions that you can." Correct posture can help prevent pain. Dr. Vanjara teaches children how to hold their gadgets correctly. She tells a patient to hold the gadget in front of the face. She says that bending the head down to look at the device, strains the neck and creates an unhealthy bend to the back. Sadia Vanjara predicts we will see not only physical but psychological and emotional problems resulting from overuse of gadgets. Experts advise taking breaks from using a computer or other device often. Stand up. Stretch your legs, back, shoulders and arms. And when your work or school work is done, unplug and exercise.

Do you remember the good old days? Innocent times spent sharing documents and executable files without a care in the world. Okay, every month or so you might encounter a boot sector virus -- but they were easy to deal with even if the anti-virus software didn't pick them up. But those long lazy summers disappeared too fast. Macro viruses made Information Technology (IT) administrators grow up fast as they realized there was a type of virus which could spread very quickly throughout an organization. It wasn't unusual to find hundreds of computers within personal company infected by viruses transmitted via email attachments. The IT staff were amongst the fittest departments in your company, running from Personal Computer (PC) to the next cleaning them up. There had to be a better way. Companies now realize that viruses aren't "urban myths", and can have a serious impact on their operations. They invest in anti-virus software on the desktops, servers and email gateways and even put in place procedures to ensure their anti-virus is up-to-date with the very latest detection routines. It sounds like companies have put in place adequate defenses to protect against viruses. But have they? Anti-virus software detects most of the viruses your users are likely to encounter -- often without the user even knowing. However, the software must be updated regularly, preferably daily in any large company. Even then, a very new virus can infect your users. With the rapid transmission of files through networks and the Internet, a virus can spread a considerable distance before it can be identified and protected against. Fortunately, only a few viruses ever do this but the likes of Melissa and the Love Bug can inflict serious damage before their progress is stopped. While employees become suddenly aware during the ensuing media excitement, they soon forget about the virus threat as the stories disappear from the news headlines. This is the danger. Complacency can set in when there is no perceived "action" on the virus front with no global crisis, and the importance of being vigilant about viruses recedes in your users' minds. They forget what the big deal was in the first place -- after all, anti-virus software deals with the viruses, doesn't it? And isn't it the IT department's job to look after this sort of thing? Before you know it your users are opening unsolicited attachments once more, downloading unauthorized software, and putting your company's data and credibility at risk. All because the users think that they are working in a safe environment. Employees see anti-virus software, firewalls and IT departments as guarantees that their computers will work and be safe. Of course, there aren't any guarantees. Anti-virus software plays one, albeit important, part in the defense of your company from malicious attack but the security of your computer system is only as strong as the weakest link. And that, more often than not, is the human factor. No employer wants to come across as a killjoy or an ogre. Most will willingly accept that the happiest employees are those who feel that they are respected and trusted by their employer. Many companies accept that employees will send and receive a certain amount of personal email and make the odd personal telephone call. However, the worry comes when employees start risking company security in pursuit of personal amusement. Funny screensavers and games downloaded from the Internet can seem harmless enough but they could easily be harboring a dangerous virus. Software downloaded from the net is often unlicensed and unsupported, and may cause conflicts with existing software in use at your company. Unlicensed, pirated software is an ideal vector for a computer virus. Virus writers and hackers often use such software as the ideal "kick-start" for their virus distribution. It is vitally important that employees be educated about the virus threat but this cannot be a one-off event. The potential threat should always be in the back of an employee's mind and precautionary measures should be taken as a matter of course. There is no harm in reminding people about what could happen if they let their guard down. In the end, education is the key to a virus-free environment and this is a continual process. It may not be the most exciting thing on the agenda but it works. The lesson is simple. You can have the best software in the world protecting your company's defenses; you can even be the biggest IT company in the world; but without your users practicing safe computing they will always be the weakest link. The best way to minimize the negative influence that computer viruses may bring is _ .
[ "to get the best, up-to-date software", "to have the best IT department", "to educate computer users", "to download free software" ]
C. to educate computer users

If you have ever experienced jet lag ,you know how much of a drag it can be. Jet lag happens as a result of air travel, when traveling between two or more time zones. Your body is used to operating in a certain time zone, and when its timing is affected, you're likely to have problems. Edward Norton's character in the movies Fight Club faces the struggle of jet-lag-induced sleeplessness due to his constant traveling. Sleeplessness is just one of the effects of jet lag, and it can lead to other problems, such as tiredness, memory loss and confusion. That's not something you should have to fight on a business trip and it certainly won't make your vacation very enjoyable, either. Sleeplessness is the biggest problem for travelers that suffer from jet lag. Don't worry. You can do something to prevent it. Modify Your Body Clock To prevent the effects on your body's timing that come with crossing time zones, you need to change your body clock sooner, rather than later. You can do this by putting yourself on the same time as your destination time zone before you fly. If you know that you will be traveling to London from the eastern United States, you'll have a five-hour time difference to deal with. Plan for it. Avoid Heavy Food and Alcohol Part of the pleasure of flying commercially, especially if you fly business or first class, is taking advantages of the food and drinks. If you want to avoid jet lag, though, you should think twice. Eating heavy food will only make the jet lag worse. It isn't good to drink alcohol during a flight, either, because it may make you drowsy. Wait until your body adjusts before you decide to have heavy food or drink alcohol. According to the passage, in order to prevent jet lag, you should_.
[ "sleep for the whole flight", "drink little alcohol", "not fly business class", "know your destination well" ]
B. drink little alcohol

Emotional eating is when people use food as a way to deal with feelings instead of to satisfy hunger. We've all been there, finishing a whole bag of chips out of boredom or eating cookie after cookie while _ for a big test. But when done a lot -- especially without realizing it -- emotional eating can affect weight, health, and overall well-being. Not many of us make the connection between eating and our feelings. But understanding what drives emotional eating can help people take steps to change it. One of the biggest myths about emotional eating is that it's prompted by negative feelings. Yes, people often turn to food when they're stressed out, lonely, sad, anxious, or bored. But emotional eating can be linked to positive feelings too, like the romance of sharing dessert on Valentine's Day or the celebration of a holiday feast. Sometimes emotional eating is tied to major life events, like a death or a divorce. More often, though, it's the countless little daily stresses that cause someone to seek comfort or distraction in food. Emotional eating patterns can be learned: A child who is given candy after a big achievement may grow up using candy as a reward for a job well done. A kid who is given cookies as a way to stop crying may learn to link cookies with comfort. We're all emotional eaters to some extent. But for some people, emotional eating can be a real problem, causing serious weight gain or cycles of binging and purging. The trouble with emotional eating (apart from the health issues) is that once the pleasure of eating is gone, the feelings that cause it remain. And you often may feel worse about eating the amount or type of food you did. That's why it helps to know the differences between physical hunger and emotional hunger. Next time you reach for a snack, check in and see which type of hunger is driving it. The author of the passage would agree that _ .
[ "we can do nothing to change emotional eating", "we should only eat when we are hungry", "we should be careful with emotional eating", "we should not seek for comfort in food" ]
C. we should be careful with emotional eating

Can you speak to dolphins? Of course you can but you won't be able to understand them! We interviewed a biologist and asked her what research on dolphin communication has shown. This is what she told us. Just like dogs, cats and other mammals, dolphins communicate by using sound, vision , touch and taste. Each dolphin has its own signature whistle to identify itself and to call others. Dolphins don't have the ability to smell, but their hearing and eyesight are excellent. We also asked Jane if dolphins have got their own language. She told us that they have and that dolphins started talking to each other from birth. They make different sounds, including whistles, squeaks and click. Sometimes they even sound like a heavy metal band! We then asked Jane if any interesting experiments have been done. She told us that a very interesting experiment had been done with a mother dolphin and her two-year-old baby in an aquarium. They talked to each other over the telephone! The two dolphins were in separate tanks which were connected by a special under water system. Unfortunately the biologists couldn't understand what the dolphins were talking about because they haven't been able to decode dolphin language yet. However, it was very clear that the dolphins knew what they were talking about. Finally we asked Jane if there was hope that we would be able to understand dolphins in the near future. She told us that she and her team have been listening to dolphins for more than 17 years, using special equipment to record and analyze their language. Unfortunately they haven't been able to decode it yet, but who knows -- maybe one day we'll get a phone call from a dolphin. It's clear that _ .

One of today's hottest topics among women (and to an extent among men too now) is anti aging and how to reverse the signs of age.The beauty industry has responded to this by offering a wide collection of anti aging creams and other anti aging products aimed at all pocketbooks,ranging from economical to highly priced. And the question is "do any of these often much-vaunted anti aging creams actually work?" And if they do,how precisely do they perform their miracles? Well the appropriate response to that is that they do work - after a fashion.There certainly are anti aging creams available for a ly modest price that will reduce the appearance of wrinkles in a comparatively short period of regular application.But this really is the limit of their powers: they won't actually undo skin damage or eradicate all signs of age;they will simply modify them,some more effectively than others. The way they work is like so: they remove upper layers of dead skin cells and make deeper layers absorb water,serving to plump them up and make them look fuller and healthier.But since such anti aging creams only go skin deep,as it were,skin damage will reappear once you stop using the anti aging wrinkle cream. This means fairly heavy regular use,which might be costly depending on your choice of product.However,if you can afford it or think it's worth the cost,it won't be such an issue.After all,what woman wants to look older than her years when looking good is so tied up with many women's self-esteem and sense of identity. A compromise solution for those _ is to use the cheaper creams.In addition,it's always wise to be a little experimental to make sure you end up with the one that suits your skin best. So,to sum up: an anti wrinkle face cream will work within limits,depending on your objective. This passage mainly tells us something about _ .

It is said that there's no such thing as a free lunch, but even if you manage to bag a bargain meal, it will not taste as good as a more expensive choice, according to scientists. A new study has found that restaurant goers who pay more for their meals think the food is tastier than offered for a smaller price. The experts think that people tend to associate cost with quality and this changes their perception of how food tastes. Scientists at Cornell University studied the eating habits of 139 people enjoying an Italian buffet in a restaurant. The price of the food was set by the researchers at either $4 or $8 for the all-you-can-eat meal. Customers were asked to rate how good the food tasted, the quality of the restaurant and to leave their names. The experiment showed that the people who paid $8 enjoyed their meal 11% more than those who ate the "cheaper" buffet. Interestingly those that paid for the $4 buffet said they felt guiltier about loading up their plates and felt that they overate. However, the scientists said that both groups ate around the same quantity of food in total. Brian Wansink, a professor of consumer behavior at the university, said: "We were fascinated to find that pricing has little effect on how much one eats, but a huge effect on how you interpret the experience." He thinks that people enjoyed their food more as they associated cost with quality and that small changes to a restaurant can change how tasty people find their meals. In a previous study, researchers from the university showed that people who eat in bright lighting consume more than people who eat in less brightly lit areas. The passage is intended to _ .

New findings show that musical training affects the structure and function of different brain areas, how those areas communicate during the creation of music, and how the brain interprets and combines sensory information. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. These views suggest potential new roles for musical training including training plasticity in the brain, offering an alternative tool in education, and treating a range of learning disabilities. Today's new findings show that long-term high level musical training has a broader effect. Researchers found that musicians have a better ability to combine sensory information from hearing, touch, and sight. The age at which musical training begins influenced brain structure and its function. Beginning training before the age of seven has the greatest effect. Even older adults who took music lessons as children but haven't actively played an instrument in decades have a faster brain response to a speech sound than those who never played an instrument, according to a study appearing November 6 in the Journal of Neuroscience. The finding suggests early musical training has a lasting, positive effect on how the brain deals with sound. "Playing a musical instrument is a multi-sensory and motive experience that creates emotions and movements--from finger tapping to dancing -- and engages pleasure and reward systems in the brain. It has the potential to affect brain function and structure when done over a long period of time," said Gottfried Schlaug, MD, PhD, of Harvard Medical School, press conference speaker, also an expert on music. "As today's findings show, musical training brings about new processes within the brain, at different stages of life, and with a range of effects on creativity, cognition , and learning," he added. According to the passage, we learn that _ .

EDGEWOOD-Every morning at Dixie Heights High school,customers pour into a special experiment:the district's first coffee shop run mostly by students with special learning needs. Well before classes start,students and teachers order Lattes,Cappuccinos and Hot Chocolates.Then,during the first period,teachers call in orders on their room phones,and students make deliveries.By closing time at 9:20a.m.,the shop usually sells 90drinks."Whoever made the chi tea,Ms.Schatzman says it was good,"Christy McKinley,a second year student,announced recently,after hanging up with the teacher. The shop is called the Dixie PIT,which stands for Power in Transition.Although some of the students are not disabled,many are,and the PIT helps them prepare for life after high school.They learn not only how to run a coffee shop but also how to deal with their affairs.They keep a timecard and receive paychecks,which they keep in check registers. Special-education teachers Kim Chevalier and Sue Casey introduced the Dixie PIT from a similar program at Kennesaw Mountain High School in Georgia.Not that it was easy.Chevalier's first problem to overcome was product-related.Should schools be selling coffee?What about sugar content?Kenton County Food Service Director Ginger Gray helped.She made sure all the drinks,which use non-fat milk,fell within nutrition guidelines.

Here's one number to keep in mind during your next cell phone conversation: 50. A new experiment shows that spending 50 minutes with an active phone pressed up to the ear increases activity in the brain. This brain activity probably doesn't make you smarter. When cell phones are on, they emit energy in the form of radiation that could be harmful, especially after years of cell phone usage. Scientists don't know yet whether cell phones are bad for the brain. Studies like this one are attempting to find it out. The 47 participants in the experiment may have looked a little strange. Each one had two Samsung cell phones attached to his or her head -- one on each ear. The phone on the left ear was off. The phone on the right ear played a message for 50 minutes, but the participants couldn't hear it because the sound was off. With this set-up, the scientists could be sure they were studying brain activity from the phone itself, and not brain activity due to listening and talking during a conversation. After 50 minutes with two phones strapped to their heads, the participants were given PET scans. The PET scan showed that the left side (the side with the phone turned off) of each participant's brain hadn't changed during the experiment. The right side of the brain, however, had used more glucose, which is a type of sugar that provides fuel to brain cells. These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that the brain cells there were active -- even without the person hearing anything. That activity, the scientists say, was probably caused by radiation from the phone. Henry Lai, who works at the University of Washington in Seattle, is uncomfortable with the data related to cell phones. Holding a cell phone to your ear during a conversation is "not really safe," Lai told Science News. Lai is a bioengineer at the University of Washington in Seattle. He wrote an article about the new study for a journal, but he did not work on the study. Bioengineers bring together ideas from engineering and biology. For those who don't want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely. You can have short and sweet conversations, use a speakerphone or keep the phone away from your head. Why weren't the participants allowed to have a conversation on the phone during the experiment?
[ "Because that would be too noisy and bad for the experiment.", "Because they really looked strange and no one wanted to talk to others.", "Because they were given PET scans and they lost the ability to talk.", "Because the scientists want to be sure of the accuracy of the experiment." ]

The days are getting shorter and shorter, and temperatures are dropping. Winter is coming and it is easy for people to catch flu. Many people have started taking vitamin C pills as a precautionary way. But a research has shown that vitamin C pills do not provide as much protection as they think. They are even not as good as other ways, like often washing your hands. Some German scientists have given people information and a test on the subject helping to stop incorrect ways. Whether it is caused by cold or flu , a runny nose and sore throat are signs of catching a cold. Many people overestimate the advantages of vitamin C and other pills. For years it was believed that taking vitamin C pills not only provided protection against colds but also against cancers, helping people to live longer. But the result of the research showed disagreement on these beliefs . The result has now come out on the website wwww.informedhealthonline.org. "Some pills may not help people live longer. Some pills may even lead to earlier death," says Professor Peter Sawicki. Scientists also say that the best way to get vitamins is through food instead of having vitamin pills. That is to say, we disagree with the way of taking vitamin C pills. There are many simple but useful ways to lower the risk of catching a cold. These include often washing your hands with normal soap and water and not touching your face with your hands. People who have already had a cold can stop it from spreading by throwing away tissues at once after using them and not shaking hands with other people. About taking vitamin C pills, _ is shown by the research.

A Southampton University team found that people who were vegetarians by 30 had recorded five IQ points higher on average at the age of 10. Researchers said it could explain why people with a higher IQ were healthier as a vegetarian diet was connected to lower heart disease and obesity rates. The study of 8,179 people was reported in theBritishMedicalJournal. Twenty years after the IQ tests were carried out in 1970, 366 of the participants said they were vegetarians -- although more than 100 reported eating either fish or chicken. Men who were vegetarians had an IQ score of 106, compared with 101 for non-vegetarians; while female vegetarians averaged 104, compared with 99 for non-vegetarians. There was no difference in the IQ scores, between strict vegetarians and those who said they were vegetarians but reported eating fish or chicken. Researchers said the findings were partly related to better education and higher class, but it remained statistically significant after adjusting for these factors. Vegetarians were more likely to be female, to be of higher social class and to have higher academic or vocational qualifications than non-vegetarians. However, these differences were not reflected in their annual income, which was similar to that of non-vegetarians. Lead researcher Catharine Gale said, "The findings that children with greater intelligence are more likely to report being vegetarians as adults, together with the evidence on the potential benefits of a vegetarian diet on heart health, may help to explain why a higher IQ in childhood or adolescence is linked with a reduced risk of coronary heart disease in adult life. But Dr Frankie Phillips of the British Dietetic Association said," _ Do people become vegetarians because they have a very high IQ or is it just that they are clever enough to be more aware of health issues?"

Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no. "We don't know whether the food is safe," said Zambia's commerce, Trade and Industry Minister Dipak Patel. His worries are shared by countries around the world that are in two minds about America's genetically modified(GM,)crops.Just last week, EU member nations were discussing whether or not to import GM sweet corn from the US. Ever since people started farming, they have tried to crossbreed plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other. But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature. This means they can make crops more productive and resistant to disease by adding genes from other species.They can also create food with special characteristics, such as "golden rice", which is enriched with vitamin A. But many people believe GM foods are a health risk. At the moment, the official argument is that GM foods "are not likely to present risks for human health". But there are still many questions to be answered as the foods are produced in different ways. Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops. People in China are also getting worried about GM foods. More than 70 percent of the country's soybean oil is produced from imported GM soybeans. Meanwhile, an investigation last November found that 12 of 60 famous foods sold across the country were GM products. The government has begun to introduce a marking system for GM goods so that people can choose whether or not to eat them. Which is the best title for the passage?

We're all connected. You can send an e-mail message to a friend, and your friend can pass it on to one of his or her friends, and that friend can do the same, continuing the chain. Eventually, your message could reach just about anyone in the world, and it might take only five to seven e-mails for the message to get there. Scientists recently tested that idea in a study involving 24,000 people. Participants had to try to get a message forwarded to one of 18 randomly chosen people. Each participant started by sending one e-mail to someone they knew. Recipients could then forward the e-mail once to someone they knew, and so on. Targets, who were randomly assigned by researchers from Columbia University in New York, lived in 13 countries. They included an Australian police officer, a Norwegian veterinarian, and a college professor. Out of 24,000 chains, only 384 reached their goal. The rest petered out, usually because one of the recipients was either too busy to forward the message or thought it was junk mail. The links that reached their goal made it in an average of 4.05 e-mails. Based on the lengths of the failed chains, the researchers estimated that two strangers could generally make contact in five to seven e-mails. The most successful chains relied on casual acquaintances rather than close friends. That's because your close friends know each other whereas your acquaintances tend to know people you don't know. The phenomenon, known as the strength of weak ties, explains why people tend to get jobs through people they know casually but aren't that close to. So, start networking and instant messaging now.

You may think your bathroom is often full of bacteria and so you give it a complete cleaning once a week. But how often do you clean out and disinfect your fridge? Well, probably not often enough, according to a recent study, which found out that the fridge is the second dirtiest place in your house, just behind the bathroom. Fridge temperatures were often set too high, allowing the growth of bacteria, which included E.coil, Enterobacteria, and S. aureus, all of which will give you an easy access to food poisoning. So what can you do to ensure your fridge---and your food in it---is not a health threat? For starters, clean the fridge weekly---wipe it and repeat. Make sure your fridge is at the correct temperature for storing food, between 0 and 5 degrees centigrade. Your freezer should be below-18 degrees centigrade. You can use fridge and freezer thermeters to make sure this is the case. Some modern fridges have zones to store different types of food ,such as meat and vegetables. Make sure you don`t store meat in the vegetable zone, as the temperature there might be higher. Make sure you don not leave the door open too long as the temperature in the fridge will quickly rise, creating a breeding ground for bacteria. Cover food that has not been finished, and eat it within a couple of days. Keep bottles and jars closed. Keep raw meat away from cooked meat. Both should be well covered to prevent pollution. Store raw meat at the bottom of the fridge to stop juices dripping onto other foods. Finally, use common sense, and throw away old food. The purpose of this text is to _ .

The longest solar eclipse of the century cast a wide shadow for several minutes over Asia and the Pacific Ocean on 22th July, drawing people outside to watch the sight in the sky. Day turned into night. Temperature turned cooler in cities and villages filled with fans of astronomy. The total eclipse could be seen starting in India on Wednesday morning and moving eastward across China and parts of the Pacific. Millions cast their eyes towards the heavens to catch an unusual view of the sun's colorful ring. Cloud in some areas prevented people from fully enjoying the sight. Still, many were frightened. The total eclipse occurs about twice a year as the moon passes between the earth and the sun on the same plane as earth's circle. The local astronomy society gave a flash on how an eclipse happens. Wednesday's event lasted up to more than six minutes in some places. In India, thousands bathed in the Ganges River in the Hindu holy city of Varanasi to clean their souls. It was sunny sky in Hong Kong for the eclipse, where students, parents and the elderly flooded in a primary school to watch. In Shanghai, children climbed up ladders to look through two large telescopes on the school roof to catch sight of the moon moving across the sun. Others looked through a pair of glasses covered with solar filter paper, where they could take pictures of the moon moving over the sun. In some cultures, many old stories are about eclipse.

There are some strong-minded people that are able to stop smoking today and be free from the addiction the next day. However, some smokers may have to seek help from medication in order to kick the habit. What medication actually does is to reduce the wish to smoke. Some of the medication must be taken with a doctor's guidance. The five most common medications to stop smoking are Bupropion SR, nicotine gum, nicotine inhalers, nicotine nasal spray and nicotine patches. People can buy nicotine gum and nicotine patches in chemists. However, the other medications require a prescription. Zyban tablets have been found to be highly effective in curing people of smoking addiction. The tablet needs to be taken whole, without crushing it, as crushing can lead to side effects. It can be bought on the prescription of a doctor. Nicotine patches are filled with nicotine and they are applied to the skin. The skin takes in the nicotine and carries it to the blood stream. The amount of nicotine in these patches is quite limited, not enough to lead to addiction. But you shouldn't take them for dinner. In fact, millions of people have benefited from these nicotine patches. Nicotine gum is supposed to be a safer choice. It is used in such a way that it comes into contact with the blood vessels in the mouth and then releases the nicotine. The nicotine should not go through the stomach; otherwise, it may cause certain side effects. These different types of medications have to be taken quite carefully.

The children can have a school dinner-a hot, cooked meal; or they can take a packed lunch with them, which usually includes cold food like sandwiches. Often parents know what their children want. Cath, a mother of three children, told us, "My children have packed lunches because they say they don't like to have school dinners. So I make three packed lunches every morning." However, another mother, Susan, made a different choice. She said, "My daughters have a always had school dinners. I think they probably get healthier food at school than a few sandwiches I make for them." But how healthy are school dinners? Kaz, a father, thought poorly of them. He said, "Fizzy drinks were offered and I think there were a lot of chips." Jamie Oliver spent a year working in a school kitchen.

Everyone makes mistakes in life, but for whales and dolphins, the "mistake" of landing on the shore costs the highest price---their lives. People living along the coast of Australia and New Zealand have been shocked and saddened by the number of whales and dolphins that they have found on their beaches recently. Since November 28th, 96 whales and dolphins have died in Australia and 53 whales died in New Zealand. Although 20 whales were saved, some of these were not expected to live, as they were too weak to swim with the others back to sea. Bob Brown, leader of Australia's Green party, said the mass beaching was caused by the recent "sound bombing" of the ocean floor between the two countries. This is a method of testing for oil and gas reserves . But mass beaching of whales has long puzzled scientists. Typically most members of the stranded group will appear to be perfectly healthy. "Some researchers believe that close relationship within the group causes the problem, if one gets into trouble, the others will not leave" said Shery Gibney, a leading biologist in New Zealand. "Some will come in and try and assist it; if they get trapped on the beach, then more will come." Another common theory is that the whales' navigation system are thought to break down in some way. It has been said that whales follow electromagnetic patterns in the sea-bed. The whales can get confused because these patterns sometimes change. That would be a bit like a new roundabout being built on a road you were used to driving on. You might be confused for a minute when you come to it for the first time, and you might even take a wrong turning before getting back on your route. A different idea is that when whales chase fish for food they end up in shallow waters because they are not paying attention to where they are going. And yet, from time to time a group will swim on purpose into shallow waters and end up on the beach, where they die. If returned to the sea, some whales often show great determination in restraining themselves. _ whales and dolphins would probably die in this mass beaching along the coast of Australia and New Zealand.

Different from popular thoughts, colds are not caused by bad weather. Colds are caused by viruses in the body, and you are better out on the snowy day than you are in a warm room, with your friends, who just may be passing the virus around. If you feel a chill when you are coming down with a cold, you are already sick. A chill is an early sign of the cold. The virus can spread through air when a cold - sufferer coughs or sneezes. Surprisingly, this is not the most usual way of spreading, Many studies have now shown that most colds are " caught " by hands. A cold - sufferer rubs her nose, so spreading the virus to her hand. Then a friend comes to visit her. They shake their hands. The friend then gets something to eat by hand, and several days later she catches a cold. Although some parents pick up their children's tissues and carefully throw them away, they fail to wash their hands. They'll catch the colds, too. Cold viruses can also be spread by objects, for example, telephones, plates. The cold - sufferer as well as other members of the house, by washing their hands often, will stop the viruses from spreading in a way . Which of the following sentences is true in the passage ?

The oldest and hardest cow beef may be made as tender and tasty as young and choice met. "This declaration was made by the French physicist Denis Papin in book published in 1681, which described his "New Digester" or pressure cooker. It was a cast iron pot with an air-tight lid, which allowed liquids to boil at a higher temperature than usual, and so it cooked food in a quarter of the time. The food was cooked by pressurized steam being forced through it at about 121degC. All pressure cookers were made of cast iron until 1905, when the first aluminum model was made in America. In 1938, Alfred Vischer, a man from Chicago, U. S. A., designed a simple interlocking pan and lid, and an improved pressure-tight seal --a replaceable rubber sealing ring. When Vischer's patent expired in 1954, many companies entered the field, and the rapid pressure cooker became popular with people with people who had little time to cook or had to supply food for unexpected guests.

The charity Alcohol Concern is running a campaign of restriction by encouraging people to have a dry January. Jackie Ballard, the charity's Chief Executive, believes the campaign has been successful in recent years. She says, "More than two-thirds of people even six months later are drinking at reduced levels having had a month off drink. But also a study has shown the impact it has on people's health reducing their blood pressure and blood sugar levels." The study by the University of Sussex followed up nearly 900 participants in Alcohol Concern's Dry January campaign and found out that 72%of them had kept harmful drinking sessions down and 4%were still not drinking. Moderation seems to be the key to everything. The official recommendation for women is not to regularly drink more than 2 to 3 units of alcohol a day. The limit for men is 3 to 4 units of alcohol -- no more than a pint of 5.2%ABV lager, beer or cider. The result of dry January campaign is that _ .

Imagine being able to recall just about anything, your mind functioning as a nearly endless encyclopedic book of names, pictures, dates and events. Brad Williams' excellent memory recall makes him a personified version of Google. His wide memory allows him to recall almost any news event and anything he has experienced, including specific dates and even the weather. "I was sort of a human Google for my family. I've always been able to recall things," the 51-yearold said on Good Morning America in his first television interview. Williams' type of detailed, complete memory is called hyperthymesia and few known cases exist. Brad's brain scan are now being studied by scientists at the Center for Neurobiology of Learning and Memory, at the University of California. At first, the drive-time radio broadcaster didn't think his ability to recall so much was anything special. Gradually, over the years, other people noticed how much he was able to remember in detail about events. Then in 2006, he read an article about a wman whom scietists called AJ, which _ Williams to come forward. AJ is a writwer of a medical journal, and the only scientifically-documented case of superior memory. "When I read about AJ, my immediate thought was : Oh my God. That's Brad!" said williams' brother, Eric Williams. Eric Williams is eager to learn about the inner working of his brother's mind. He is in the process of making documentary about Brad, appropriately titled: "Unforgettable." In the film, which hasn't been finished yet, Williams takes on a person who is Googling answers to 20 questions. He answers 18 of them correctly and is 11 minutes faster than the Google user.

You have waited 45 minutes for the valuable 10 minutes' break. But when the bell for the next class rings, you can't believe how quickly time has passed. If you have this experience, you'll know how time flies when you are having fun and _ when you are bored. Now scientists have come up with a reason why this happens. They have found that the brain changes its way to work according to how we direct our attention to a task. When we are bored, we pay more attention to how time is passing. And this makes our brains think the clock is ticking more slowly. Recently some researchers who want to understand the conditions carried out an experiment. In the experiment, twelve volunteers watched a picture while researchers monitored their brain activity. The volunteers were told to first notice how long a picture appeared, then the color of the picture, and thirdly, study the both. The results showed that the brain was more active when the volunteers paid attention to more subjects. It is thought that if the brain is busy noticing many aspects of a task, it has to spread its resources, and pays less attention to the clock. Therefore, time seems to go quickly. If the brain is not so active, it spends its full energy on the passing of time. As a result, time seems to move slowly. Next time you feel bored in class, perhaps you should concentrate on what the teacher is saying. What have the scientists found?

It's hard to track the blue whale, which has almost been killed off by commercial whaling. Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when, with the help of the US Navy, they are able to track a particular blue whale for 43 days recording its sounds. This was possible because of the Navy's former top secret system of underwater listening devices across the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely observing a deep-sea volcanic eruption for the first time and that they planned similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in the ocean and global temperatures. Different layers of ocean water can act as channels for sounds focusing them in the same way a stethoscope does when it carries faint noises from a patient's chest to a doctor's ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles. The deep-sea listening system makes use of _ .

Research led by UK and Australian scientists sheds new light on the role that our ancestors played in the extinction of Australia's prehistoric animals. The new study provides the first evidence that Tasmania's giant prehistoric animals were still living on the island when humans first arrived. The findings suggest that the mass extinction of Tasmania's large prehistoric animals was the result of human hunting, and not climate change as previously believed. Scientists have long argued over the reasons behind the worldwide mass extinction that took place towards the end of the last ice age. The main _ are generally thought to be climate change or some form of human impact. People only arrived in Tasmania around 43,000 years ago, when the island became temporarily connected by a land bridge to mainland Australia. None of Tasmania's giant animals, known as "megafauna" were known to have survived until this time. This appeared to clear humans of any involvement in the disappearance of the island's large megafauna. This new international study reports the discovery of giant kangaroos surviving in Tasmania until people arrived, placing humans back on the list of likely culprits for the extinction of the megafauna. Using the latest techniques, the team were able to determine the age of the fossilized remains of the megafauna more accurately than ever before. The results showed that some of these animals survived until at least 41,000 years agomuch later than previously thought and up to 2,000 years after the first human settlers arrived. As climate in Tasmania was not changing dramatically at this time, the researchers argue that this is evidence of these species being driven to extinction through over-hunting by humans. It can be inferred from the results of the new study that after humans arrived in Tasmania _ .

A home computer not only helps children master the old ways of learning, but also opens up possibilities that simply aren't available in traditional education. Some software, for example, allows kids to make decisions and see the results in different situations. The World Wide Web encourages young minds to move easily from link to link, topic to topic. The best software draws children into learning by making them curious--what if I click on this picture, drag this over here, visit that website? Knowing how to use a computer also encourages a child's confidence. Kids figure out quickly that computers are powerful, and mastering the machine makes them feel grown-up. In turn, feeling confident on a computer often translates to academic confidence. Researchers have found that attitudes toward writing, for example, improve when students write on a computer. Perhaps most importantly, computers can enrich family life. Forget the idea that computer kids are separated. Children like to use the computer with adults and other kids, asking questions and comparing results. "The Internet is a unique opportunity to bring resources home, "notes Susan Haugland, PhD, Cape Girardeau, Mo. , author of Computer and Young Children:A World of Discovery.

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! The passage mainly tell us _

A study by St. Louis University has found that a lovable dog named Sparky and a robotic dog AIBO, were about equally effective at reducing the loneliness of nursing home residents. The study confirmed previous findings that dogs have a good effect on nursing home residents . Dr. Andrew Smith led the Stanford University teamat built a home-assistance robot. "If humans can feel an emotional tie with robots, some day they could be not just our assistants, but also our companions," he said. To test whether residents responded better to Sparky, a trained dog, or the Sony-made robotic dog, researchers divided 38 nursing home residents into three groups at three long-term care centers in St, Louis. One group had weekly 30-minute one-on-one visits with Sparky; another group had similar visits with AIBO; a control group had no contact with either dog.The groups' respective levels of loneliness were tested by having them answer a number of questions at the beginning and near the end of the visits. After two months, both groups that had contact with the dogs were less lonely and more attached. Most of the elderly regarded Sparky, a 9-year-old dog, as an audience for their life stories, said investigator Marian Banks. "He listened attentively, wagged his tail, and allowed them to pet him," said Banks, who adopted and trained Sparky after finding him in a street behind her home seven years ago. Those who were together with AIBO took a little longer to warm to the robotic creature.Over time, however, they grew comfortable with him, and petted and talked to him. He would respond by wagging his tail, vocalizing , and blinking his lights. "AIBO is charming once you start to interact with him," said the study's author, Dr. William Banks, " He's an attractive sort of guy. He gives a feeling: of being personal, not just a robot.
