For each question there are 4 choices marked A), B), C), and D). Choose the ONE answer that best completes each sentence.Passage 11 Vitamins are a group of substances found in food. The body needs them for life and health. So naturally, many people are concerned with the question: Am I getting enough vitamins, and am I getting the right kind2 Even though very small amounts of each vitamin are enough for the needs of the body, that many people have not enough vitamins has some basis. And this has something to do with their diet — the food they take in. A person eating a good variety of foods gets all the vitamins now known to be needed with the possible exception of vitamin D. The problem is that there are many people who don’t choose foods wisely, don’t get enough variety, and don’t eat the basic foods they need to get their v itamins. So the answer to this question is: No extra vitamins are needed, if you eat proper food. In fact, many of the vitamins can not be stored in the body, so when extra vitamins are taken in, the body simply gets rid of them. It is even harmful to put too much of certain vitamins into the body. This has been found to be true of vitamin A and D, when large amounts are taken in.3 What foods supply what vitamins Here is a general idea. Vitamin A, for the health of the eyes, skin, teeth, and bones, is found in green vegetables, fruits, eggs, liver and butter. Vitamin B1 which helps the nervous and digestive systems and prevents certain diseases, is found in cereals, pork and liver. Vitamin B2 is found in milk, eggs, green vegetables and meats. Vitamin C, which helps bones and teeth, is found in tomatoes, certainfruits and vegetables. These are only a few of the most important vitamins the body needs.1. Our body needs ___A___ for life and health.A) small amounts of each vitamin B) extra vitaminsC) all vitamins except vitamin D D) large amounts of certain vitamins2. C Vitamin A is needed by___C_ and can be found in ______.A) bones, pork B) nervous system, milkC) eyes, green vegetables D) teeth, meats3. A Vitamin B1 is very important to __A____.A) the digestive system B) bones C) liver D) skin4. What will be the result if you take more vitamins than you really need DA) They will do great harm to our body. B) We get all the vitamins needed.C) Our body will function more properly. D) Our body simply gets rid of them.5. The passage has probably been taken from _B_____.A) a sports magazine B) a journal of medical scienceC) an aged magazine D) a youth journalPassage Two1 Many centuries ago, a group of Jews (犹太人) landed in India and immediately went to the king. They told him that they were lost and wanted to settle in his kingdom.2 In those days any foreigner was viewed with suspicion (怀疑), so the king was hesitant about letting them in. He sent for one glass of milk and one glass of water. He asked the leader of the Jews to taste the milk. Then he poured out some milk and added some water. He asked the leader to taste the milk again and said, “What is the difference in taste”3The leader said, “The second time the milk tastes terrible.” “That is because of the water added to the milk,” said the king.“The water dilutes the milk and spoils its taste. So too your addition (加入) will s poil the kingdom.” The leader of the Jews thought for a moment and asked for another glass of milk. He then added sugar to the milk and asked the king to taste it. “It tastes sweet,” said the king.4The leader of the Jews bowed his head and said, “Oh, ki ng！That is how we would like to live here：as the small amount of sugar which sweetens the large quantity of milk and not as the water which dilutes the milk.” Pleased with him the king granted them perm ission to stay.6. The leader of the Jews went to the king because ___C_____ for life and health.A) they wanted to ask directions B) they wanted to drink some milk C) they wanted to live there D) they wanted to go through the kingdom7. Why was the king hesitant AA) Because he was suspicious of the foreigners.B) Because in those days any foreigner was viewed as a bad guy.C) Because he thought the Jews would rob them of their milk.D) Because Jews were not trusty.8. The king asked the leader of the Jews to taste the milk added with water just to show that __B______.A) the taste was terrible B) if the Jews joined them, they would destroy the countryC) the taste was different from the pure milk D) the taste was sweet9. The underlined word “dilutes” means _____D___.A) reduce B) weaken C) make less delicious D) make (a liquid) thinner by adding another liquid such as water10. The passage implies that the leader of the Jews was ____B____.A) humorous B) witty C) foolish D) unbelievablePassage Three1 Is it difficult for you to get up in the morning Do you sometimes oversleep Are you often late for work or school Yes Then Hiroyuki Sugiyama of Japan has a special bed for you. Hiroyuki’s bed will get you up in the morning! Here is how it works:2 The bed is connected to an alarm clock. First, the alarm clock rings. You have a few minutes to wake up.

You’re still in bed! Slowly, the top of the bed rises hi gher and higher. The foot of the bed goes lower and lower. Finally, the bed is vertical. You slide off the bed and onto the floor. You are awake and out of bed.3 Hiroyuki made his bed because he wanted to win a contest. He works for Honda Motor Company. Once every two years, Honda has a contest—the “All Honda Idea Contest”.

If we are wise, we accept these failures as a necessary part of the learning process. But all too often as parents and teachers we deny this same right to our children. We tell them that failure is something to be ashamed of, that nothing but top performance will meet with our approval.2 When I see a child subject to this kind of pressure, I think of Donnie, my youngest third-grader，he was a shy, nervous perfectionist. His fear of failure kept him from classroom games that other children played with joyous abandon. He seldom answered questions — he might be wrong. Written assignments, especially math, reduced him to nail-biting frustration. He seldom finished his work because he repeatedly checked with me to be sure he hadn't made a mistake3 I tried my best to build his self-confidence. But nothing changed until midterm, when Mary Anne, a student teacher, was assigned to our classroom. She was young and pretty, and she loved children. My pupils, Donnie included, adored her. But even enthusiastic, loving Mary was baffled by this little boy who feared of making mistake.4 Then one morning we were working math problems at the blackboard. Donnie had copied the problems with painstaking neatness and filled in answers for the first row. Pleased with his progress, I left the children with Mary Anne and went for art materials. When I returned, Donnie was in tears. He'd missed the third problem.5 Mary looked at me in despair. Suddenly her face brightened. From the desk we shared, she got a canister of pencils.6“Look, Donnie,” she said, kneeling beside him and gently lifting the tear-stained face from his arms. She placed the pencils on his desk. “See these pencils, Donnie” she continued. “They belong to Mrs. Lindstrom and me. See how the erasers are worn That's because we make mistakes too, lots of them. But we erase the mistakes and try again. That’s what you must learn to do, too.”7She kissed him and stood up. “Here,” she said, “I’ll leave one pencil to you so you’ll remember that everybody makes mistakes, even teachers.” Donnie looked up with love in his eyes and just a glimmer of a smile.8The pencil became Donnie’s prize. That, together with Mary Anne’s frequent encouragement and unfailing praise for even Donnie’s small successes, gradually persuaded him that it’s all right to make mistakes — as long as you erase them and try again.16. In the author’s opinion, we should consider failures _C_______.A) a shame可耻的 B) mistakes错误的 C) acceptable可接受的 D) accessible方便的17. Donnie is a perfectionist, which means he __A______.A) cannot afford any mistakes B) often makes mistakes C) is always perfect D) seldom makes any mistakes18. Mary Anne was puzzled by Donnie because __D______.A) he bit his nails B) he adored her C) he made mistakes in math problems D) his fear of making mistakes19. Mary changed Donnie after ___A_____.A) giving him a pencil B) kneeling beside him and lifting his face from his armsC) persuading hi m that it’s ok to make mistakes D) erasing his mistakes20. This article tells us that __D______.A) the influence of a teacher is important to a student老师的影响是重要的一个学生B) there are growing pains in a student’s life这是一个学生的生命成长的烦恼C) you should erase your mistakes and try again你应该删除你的错误并再次尝试D) making mistakes is not such a big deal, as long as you try again 犯错并不是什么大不了的，只要你再试试。

The word "rural" means .A. the countryB. the stateC. mainlandD. motherlandPassage 3◎题型:材料题There are villages, towns and cities in very rural parts of Britain that face the same problems as the rest of Britain. One report shows that communities in the country side are less likely than those in urban areas to have access to good public transport, shops, post offices, pubs and other services.The report shows that:Rural areas have higher employment levels.Rural areas have a higher proportion of small, entrepreneurial businesses.School in rural areas perform better on average at GCSE (General Certificate of Secondary Education 英国普通中等教育证书).People in rural areas are healthier and live longer with mortality rates about 8% below the UK average.71% of people believe that quality of life is better in the countryside, and two thirds of people would like to move there if they could.Far more people in the countryside work in services, IT and public administration than in agriculture.Tourism in the countryside supported an estimated 380,000 jobs, whereas agriculture currently employs just over 1/2 million people.But the report also shows the problem:Farming income has fallen by 60% since 1995.In 1997, 22% of rural parishes had no bus service at all and 75% no daily bus service.That is why we are putting forward specific measures for the countryside.11.

Even the busiest government officials always take extra time to be polite and offer refreshments. No matter how busy you are, you should make time for this.The conference visit is a way of doing business throughout the Arab world. Frequently, you will have to discuss your business in the presence of strangers, who may or may not have anything to do with your business. Do not be surprised if your meeting is interrupted several times by people whocome into the room unannounced, whisper, or speak softly to the person with whom you are talking, and leave. Act as though you do not hear, and never show displeasure at being interrupted.When an Arab says "yes", he may mean "maybe". When he says "maybe", he probably means "no". You will seldom get a direct "no" from an Arab because it is considered impolite. Instead of "no", he will say "inshallah", which means, "if God is willing". On the other hand, "yes" does not necessarily mean "yes". A smile and a slow nod might seem like an agreement, but in fact, your host is being polite. An Arab considers it impolite to disagree with a guest.16. The main purpose of this article is to explain ____________.A. why you need extra time when you visit Arab countriesB. how to be polite when doing business in the Arab worldC. why Arab officials are so busyD. what Arabs say when doing business17.

You refuse a cup of tea and show pictures of your product right away.D. You look out of the window while a stranger comes in to speak with the host.18. From the passage, we know that ____________.A. when an Arab wants to say "yes", he often says "maybe"B. an Arab seldom disagrees with a guest to his faceC. when an Arab agrees, a smile and a slow nod will be givenD. "inshallah" is an English word19. Which of the following is NOT an Arab custom?A. To dislike being interrupted during their meeting.B. Often to give you a vague answer.C. Seldom to say "no" directly.D. Seldom to hesitate to start talking business in the presence of strangers.20. The writer of this passage has probably ____________.A. never been to the Arab worldB. worked in the Arab worldC. been against the Arab customsD. liked the Arab customsIII．Cloze Test (10 points)Directions:Each blank in the following passage is provided with four possible choices marked A, B, C and D.

D. （已提交）参考答案： C问题解析：Every one of us is a mother, father, son or daughter - and we all have dreams - big and small. Unfortunately, too many of us keep these dreams to ourselves because we fear what others might say. My point in writing this is to say it's OK to dream and dream big and talk about your dreams so that others are inspired to dream big too. What a world we would have if everyone did this! My dad was a dreamer. He told me that one day he was going to have a sailboat. We would go to theboat shows whenever they came to town and climb into them. My father would talk to the sales people and I would be busy pretending to sail the boat. It was fun. Then one day we went to the boat place and took out a sailboat on the ocean, what a thrill! Soon afterwards he bought his first boat and named it "LETSGO" and we sailed and sailed big bays and seas around New England. When I was older I got to be the skipper because he not only told me his dream he showed it to me and let me taste the idea on my own. Now I was inspired to dream big too. You see dreams can do wonders for you. When you believe in your dreams, they take on a life of their own. Now you start dreaming up things to do to make your inspiration a reality. More dreams, moreinspiration, then more dreams and a few more. Then one morning youwake up and the dream has come true. My dreams have taken me toso many beautiful places; I've been below the surface of the oceanwatching the beauty of coral and fish as I swim by. I've flown anairplane with pontoon floats from a lake in northern Maine and anotherdifferent plane on a flight over the Grand Canyon. I've also riddenunder my own wind blown sails. The pictures in my head are pricelessand better than any I've taken. Some of the best times I've had werelistening to older people talk about their dreams and what their dreamsdid for their lives. When I hear some of their dreams it inspires me to thinkand dream how I might do that too. I interviewed a man some yearsago who was 80-something years young. He was a sturdy man with thehands to match the story he told me. Hands still strong enough to crackthe shells of the walnuts he offered me and munched on. He hadoutlived his wife but still lived in their neat home with bookcases nearthe fireplace he no doubt built. I asked one question and I didn’ t move for hours. His story of leaving home to explore the world and learna new trade was fascinating to my young mind. But it was after hearinghis tale that I realized what he was really saying to me - not as anaspiring journalist but as a person. He told me he dreamed that hewould have a great life and he had one, so, I could dream abouthaving a great life and get one too. Just as my father had said to meearlier, here was another confirmation. I did just what they said to do, because I could do anything I wanted. Therefore, I say dream... dreambig dreams about your great life to come. I？heading out toward my next one, how about you?11.

(单选题 )I have no _______ to discuss the matter further with you.A ． desire B．appetite C ．emotion D．tendency答题： A. B. C. D. （已提交）参考答案： A问题解析：We always believe that life will be better after we get married, have ababy, than another. Then we are frustrated that the kids aren't oldenough and we'll be more content when they are. After that we'refrustrated that we have teenagers to deal with. We always tell ourselvesthat our life will be complete when our spouse gets his or her acttogether. when we get a nice car, and are able to go on a nicevocation when we retire. The truth is, there's no better time than rightnow. If not now, when? Yur life will always be filled with challenges. It'sbest to admit this to ourselves and decide to be happy anyway. One ofmy favorite quotes comes from Alfred Souza. He said. "for a long time ithad seemed to me that life was about to begin-real life. But there wasalways some obstacle in the way, something to be gotten through first,some unfinished business, time still to be served, a debt to be paid. Thenlife would begin. At last it dawned on me that these obstacles were mylife." This perspective has helped me to see that there is no way tohappiness. Happiness is the way. So treasure every moment that youhave and treasure it more because you share it with someone special,special enough to spend your time with⋯ans remember that time waits for no man. So stop waiting until you finish school, until you go back toschool; until you lose ten pounds ,until you have husband and kids; untilyour kids leave the house; until you get a new car, until you retire.Happiness is a journey, not a destination. So, work like you don't needmoney, love like you've never been hurt before; Dance like no one'swatching.11.
