根据短文理解选择正确答案。 Different vitamins are found in different foods. Then which food should be eaten to keep us healthy? Let's look at some important vitamins for the answer. Vitamin A helps to protect skin from becoming dry. It is also helpful to the eyes. Without vitamin A, you cannot see well in darkness. Vitamin A is found in animal liver and the yellow part of eggs. Sweet potatoes, carrots and other dark-coloured fruit and vegetables have something that the body can change into vitamin A. Vitamin B1 changes foods into energy and helps the heart and nervous system (神经系统) to work smoothly. Without it, we will be weak and will not grow. It is found in grains and other foods like beans, nuts, meat and fish. Vitamin B12 helps to produce red blood cells. It is found in foods like eggs, meat, fish, milk and green leafy vegetables. Vitamin C is needed for strong bones and teeth, and for healthy blood vessels (血管). It also helps wounds to heal (愈合) quickly. The body stores little vitamin C, so we must get it every day in foods like oranges, tomatoes and cabbage. Vitamin D increases the levels of calcium (钙) in the blood. Calcium is needed for nerve and muscle cells to work normally, as well as to build strong bones. Fish liver oil has vitamin D. In some countries, milk producers add vitamin D to milk so that it will be good for children.1. Without __________, we cannot see well in darkness.A. vitamin AB. vitamin BC. vitamin CD. vitamin D2.

A busy brain can mean a hungry body．We often seek food after focused mental activity，like preparing for an exam．Researchers think that heavy bouts of thinking drain energy from the brain，whose capacity to store fuel is very limited．So the brain，sensing that it may soon require more calories（卡路里） to keep going，apparentlystimulates bodily hunger，and even though there has been little in the way of physical movement or calorie consumption，we eat．This process may partly account for the weight gain so commonly seen in college students．Scientists at the University of Alabama at Birmingham and another institution recently experimented with exercise tocountersuch immoderately post--study food consumption．Gary Hunter，an exercise physiologist at U．A．B．，oversaw the study，Hunter notes that tough activity both increases the amount of blood sugar and lactate（乳酸盐）-a byproduct of intense muscle contractions（收缩）-circulating in the blood and increases blood flow to the head．Because the brainuses sugar and lactate as fuel，researchers wondered if the increased flow of fuel-rich blood during exercise could feed an exhausted brain and reduce the urge to overeat．Thirty--eight healthy college students were invited to U．A．B．'s exercise lab to report what their favorite pizza was．At a later date，the volunteers returned and spent 20 minutes dealing with selections from college and graduate--school entrance exams．Next，half the students sat quietly for 15 minutes，before being given pizza．The rest of the volunteers spent those 15 minutes doing intervals on a treadmill：two minutes of hard running followed by about one minute of walking，repeated five times．Hunter says，that should stimulate the release of sugar and lactate into the bloodstream．These students were then allowed to gorge on pizza，too．But by and large，they did not overeat．In fact，the the non-exercisers，however，consumed about 100 calories more．The study has limitations，of course．We only looked at lunch，Hunter says； the researchers do not know if the runners consumed extra calories at dinner．They also cannot tell whether other types of exercise would have the same effect as running，although Hunter says they suspect that if an activity causes someone to break into a sweat，it should also increase blood sugar and lactate，feeding the brain and weakening hunger's call．98．According to the passage， ____ may cause many college students to overeat and gain weight．A．a lot of energy-consuming mental activitiesB．numerous physical movements or calorie burningC．failure to resist the temptation of delicious food．D．bodily hunger caused by physical growth99．The underlined word"counter"is closest in meaning to ____ ．A．stimulateB．maximizeC．balanceD．prevent100．What can be inferred from the passage？ ____ A．Running is more beneficial than walking．B．Sweating in exercise can make people hungrier．C．The amount of blood sugar and lactate can affect people's appetite．D．When the brain feels exhausted，people tend to do exercise for relaxation．101．Which of the following statements is FALSE？ ____ A．Mental activities can make people feel hungry．B．Physical exercise can make people refreshed and stay hungry．C．Sugar and lactate can help energize and restore people's brain．D．It's uncertain what types of exercise can effectively feed the brain．

Entertainment is an activity designed to give pleasure or relaxation to a(n)_who may participate in it passively as in watching opera or a movie, or actively as in games.A. audienceB. onlookerC. bystanderD. viewer

[听力文本资源]People’s birth years can affect their risk of catching certain flu—probably because their first case of flu somehow sets their immune system, researchers reported. Their findings could be good news for what scientists predict about the risk of a killer flu, and they could also help researchers find better flu vaccines, the researchers said.The teams were looking at the puzzling characteristics of two kinds of bird flu that keep popping up in people: the H5N1 and H7N9 viruses. And, oddly, while H5N1 has hit young people and children especially hard, H7N9 seems to attack older people. H5N1 has infected 856 people since 2003 and killed 452 of them, WHO reports. H7N9 has infected 452 people and killed 124 of them, according to the Center for Infectious Disease Research and Policy at the University of Minnesota. The team at the University of Arizona and the University of California Los Angeles studied the numbers, examining the reports of each case, who was affected and how severely. They found an almost startling link with birth year. People born before 1968 are less likely to die or be made severely ill by H5N1.[听力文本资源]1.

阅读理解阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。A The principles about applying for jobs have altered greatly lately. In the past, people preferred a hand-written application letter．However, nowadays it is becoming more and more common to apply for a job through the Internet．You can find information on the Internet about how to apply for jobs．Information can be found about how to fulfill your application letter, the clothes that you should wear and how to carry out the interview itself． The importance of body language is often mentioned，but doesn’t always get the attention it deserves．After all，before a word has even been spoken，your body language will have already given people their first impression of you．Additionally, your body language will also give out a lot more information．Based on your body language it can be seen if you are self-confident．It can also show if you are a busy or a quiet type and it helps give an impression of whether you are speaking truthfully or not．Body language can show how ent husiastic you are and if you are a nice person．someone who will take his work seriously, but also someone who has a sense of humor and can enjoy a joke from time to time．The members of the application committee will ask you questions，but your answers won’t only be oral．The committee will not only pay attention to what you say, but also to how you say it! Body language will determine first if it ‘clicks’，and sometimes all it takes is just a few seconds．Everybody uses body language，but it takes place mostly at a subconscious（下意识的） level．Using body language appropriately, you can definitely increase your chances of getting a job．1.What kind of people is the text mainly meant for?A.

People enjoying jokes are preferred in a job interview.B One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology” rather than experiencing the natural world. Fear-producing TV and computer games are leading to serious disconnect between kids and the great outdoors, which will change the wild places of the world, its creatures and human health for the worse, unless adults get working on child’s play. Each of us has a place in nature we go sometimes, even if it was torn down. We cannot be the last generation to have that place. At this rate, kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes. “If the decline in park use continues across North America, who will defend parks against encroachment（蚕食）?” asks Richard Louv, author of Last Child in the woods. Without having a nature experience, kids can turn out just fine, but they are missing out a huge enrichment to their lives. Experts predict modern kids will have poorer health than their parents—and they say a lack of outside play is surely part o f it; research suggests that kids do better academically in schools with a nature component and that play in nature fosters（培养）leadership by the smartest, not by the toughest, Even a tiny outdoor experience can create wonder in a child. The three-year-old turning over his first rock realizes he is not alone in the world. A clump of trees on the roadside can be the whole universe in his eyes. We really need to value that more. Kids are not to blame. They are over-protected and frightened. It is dangerous out there from time to time but repetitive stress from computers is replacing breaking an arm as a childhood rite（仪式）of passage. Everyone, from developers, to schools and outdoorsy citizens, should help regain for our kids some of the freedom and joy of exploring, taking friendship in fields and woods that strengthen love, respect and need for the landscapes. As parents, we should devote some of our energy to taking our kids into nature. This could yet be our greatest cause.5. According to the passage, children without experiencing nature will .A. keep a high sense of wonderB. be over-protected by their parentsC. be less healthy both physically and mentallyD. change wild places and creatures for the better6. According to the author, children’s breaking an arm is_______. A. the fault on the part of their parents B. the natural experience in their growing upC. the result of their own carelessness in playD. the effect of their repetitive stress from computers7.In writing this passage, the author mainly intends to . A. blame children for getting lost in computer gamesB. encourage children to protect parks from encroachmentC. show his concern about children’s lack of experience in natureD. inspire children to keep the sense of wonder about things aroundC I am trying to muster (鼓起) the courage to toss_away my mobile phone to enjoy a more peaceful and ring-free life. Can you imagine not having your mobile phone? In our high-tech, in-a-hurry age, a cell-free life is a hard concept to swallow. Our mobile phones can now access the Internet, and many people feel the need to express their every thought on their blog pages. If I gave up my cell-phone, people would think I was mad. I wish I had the strength to toss away my technology. I have an office phone, a home phone, an e-mail and if people want to contact me, they can. If I'm out, people can leave a message. Do they really need to find me 24/7?However, I'm a bit like Frodo in the movie Lord of the Rings. The power of the ring is too strong and I can't let it go. Mobile phones have become necessary tools in our busy life. For most people, they hold all contacts and many of us don't write up address books any more. The latest phones carry our music, pictures, movies and everything else. We feel lost without this device and when we do misplace it, we feel cut off from our fellow. "Where have you been?" said a friend, who saw me a week after I lost my cell-phone, "I tried calling you, but you disappeared. You disappeared off the face of the Earth." See, when you don't have a mobile phone, you don't exist. I'm not really going to toss my mobile phone away, in fact. We humans are such social animals and mobile phones serve us well. So in 2009, I've decided not to serve my mobile phone. Like all machines, I can always turn it off.8. What does the underlined phrase "toss away" mean?A. give away B. get awayC. break away D. throw away9. The writer mentions Frodo to_______.A. show it is difficult to get rid of the mobile phoneB. show how much he likes FrodoC. suggest a cell-free life is what he wantsD. introduce a film ch aracter to us10. What do we know about mobile phones in the 4th paragraph?A. Mobile phones can do anything for us.B. Mobile phones have become very important in our life.C. We could not live without mobile phones.D. We would be cut off by our fellow without mobile phones.11. What can be inferred from the last paragraph?A. The writer is not really going to toss his mobile phone away.B. When you don't have a mobile phone,you don't exist.C. The writer decides not to serve his mobile phone.D. We humans can control ourselves and machines.D The world is changing so fast that English, perhaps the most worldly of languages, is struggling to keep up. Learners in the future are likely to be much younger. Young children are often said to be better at language learning than older learners but they also have special chal lenges. Young children don’t usually have the kind of instrumental motivation and determination for learning English that older learners often have. English lessons must therefore be fun and rewarding. The reasons why people learn English are also changing. Globalization is bringing together more people than ever who speak different languages and who are turning to English as the means of communication. The English learners of the future may be less worried about sounding exactly like a native speaker and more concerned about how to use English effectively in cross-cultural communication. We may be hearing more non-native speakers in dialogues and a wider range of the “New Englishes” now used around the world. Technology will allow English to come to you, rather than you having to go to a special place to learn English. Learning English has always involved both pain an d pleasure, private effort and social activity. Traditional learning provided take-it or leave-it mixes of these as well as of content but in future learners will be able to choose a plan which suits their cultural and psychological dispositions(性情), or their particular needs at that moment. They, rather than their teachers, will decide how, what and when they will learn. Above all, learning English is about communication and an important benefit of learning English is being able to exchange views and make friends with people all over the world. Despite the growing independence of learners, trusted institutions and brand names will remain important. 12. Compared to older learners, young English learners . A. are more active in learningB. are more hard-working in learningC. have more difficulties in learningD. have less lasting determination in learning13. What can we learn about the future English language? A . British English will be more popular. B. American English will be more popular. C. Most people w ill speak standard English. D. Many different kinds of Englishes will appear. 14. What can we learn from the passage? A. Future English lessons will be more interesting. B. Old people won’t have to learn English in the future. C. People will pay more attention to English pronunciation. D. Teachers will play a more important role in one’s English learning. 15. What can be inferred from the passage? A. Learning English means no pain in the future. B. English training schools will not be popular with young people in the future. C. English learners will become less independent in the future. D. More attention will be paid to personal needs in English learning in the future.

They were clumsy, _ lies, yet Simon had believed them: it did not occur to him that someone as stupid as Marie could ever successfully deceive him.A. hesitantB. determinedC. articulateD. hardy

An ethics crisis at one of the world’s most successful human embryonic stem cell laboratories has plunged the controversial field of research into a new swirl of uncertainty. The accusations surrounding Korean cloning expert Woo Suk Hwang of Seoul National University--the first scientist to grow stem cells inside cloned human embryos--has already killed a spate of planned studies that sought to prove the cells’ medical potential. The claims that Hwang may have obtained human eggs for his studies from women who felt pressured to donate are also reigniting a long-smoldering debate in the United States over the ethics of paying young women for their eggs, which are difficult to obtain but essential to the production of stem cells tailored to individuals. Egg donation, which is generally safe but occasionally leads to serious and even life-threatening complications, has been a wedge issue in the stem cell debates, linking feminists and other liberal thinkers to conservatives who favor tighter limits on stem cell research. "We’re in danger of making women into guinea pigs for this research even before there are any treatments to be tested," said Marcy Darnovsky, associate director of the Center for Genetics and Society in Oakland, Calif. "We really need clear rules that someone is enforcing." With current techniques, it takes dozens of eggs to make a single cloned human embryo, which is destroyed in the process of extracting the stem cells. That means that if the field of therapeutic cloning is to advance--a field involving the creation of cloned embryos as sources of stem cells that would be genetically matched to particular patients--a significant number of eggs will be needed both to fuel the initial research and eventually to satisfy the demands of patients. Scientists at Advanced Cell Technology of Worcester, Mass. , made the decision to pay women only after a long analysis by an ethics board created by the company, said scientific director Robert Lanza. He still thinks it is the right way to go, Lanza said, given the painful injections involved, the uncomfortable egg suction procedure, and the approximately 5 percent chance of a serious case of hormonal over-stimulation, which can require hospitalization. Others say such payments cannot help but be coercive, especially for poor women who might feel compelled to take on those risks just to make ends meet. In April, the National Academies, chartered by Congress to advise the nation on matters of science, released a report that recommended against payments for human eggs beyond expenses incurred by the donors, in part because of the "sensitivities" inherent in the creation of embryos destined for destruction. But the report’s impact remains uncertain as research institutions, fertility clinics and the biggest wild card of them all--Congress--mull the Academies’ findings.What can we learn from the opening paragraph A．Hwang paid the women for their eggs in his studies.B．The charge of Hwang re-activized the debate in U. S..C．The debate in U. S. is about whether or not pay for eggs.D．The planned studies will continue without interruption.
