I stoppedat a gas station about 50 miles from Oklahoma City, where I was planning to stop and visit a friend. While I was standing in line at the cash register (收款台), I said hello to an older couple who were also paying for gas.I took off, but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend’s. We chatted on the way into the city, and when I got out of the car, the husband gave me his business card.I wrote him and his wife a thank­you note for helping me. Soon afterward, I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.Years later, I drove to a meeting in a nearby town in the morning. In late afternoon I returned to my car and found that I’d left the lights on all day, and the battery (电池) was dead. Then I noticed that the Friendly Ford dealership—a shop selling cars—was right next door. I walked over and found two salesmen in the showroom.“Just how friendly is Friendly Ford?” I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment, so when I got home, I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you, and it meant a lot, he said.“Thank you”— two powerful words. They’re easy to say and mean so much.4. What happened when the author found smoke coming out of his car?A. The couple offered to help him.B. He had it pulled back to the gas station.C. The couple sent him a business card.D. He called his friend for help.5. The battery of the author’s car was dead because ________.A. Something went wrong with the lightsB. He forgot to turn off the lightsC. He drove too long a distanceD.The meeting lasted a whole day6. Which of the following is true?A. the salesman drove the writer home.B. The old couple worked in the gas station.C. The writer sent the couple a present..D.The salesman was very happy to receive the writer’s note.7. By telling his own experiences, the author tries to show ________.A.the kind­heartedness of older peopleB.how to deal with car problemsC.the importance of expressing thanksD. how to write a thank­you letterCOnce an old man rose early to read each morning. His grandson wanted to be just like his grandfather, so tried to emulate him every way he could.One day the grandson asked, “Grandpa, I try to read just like you do, but I don’t understand most of it, and I forget whatever I do understand immediately I close the book. So what good is it for me to read?”The grandfather, who was putting coal on the fire, said, “Take thiscoal basket down to the river and bring me back a basket of water.”The boy did as told to, but the water leaked out before he could get the basket home.The grandfather laughed, saying, “You’ll have to move a little faster.”This time he ran faster, but again the basket emptied. Out of breath, he decided it was impossible to carry water in a basket, and he went to get a bucket（桶）. But the grandfather said, “I want a basket of water instead of a bucket of water. You’re just not trying hard enough.”The boy knew what he was trying to accomplish was impossible. However, he decided to show his grandfather a third time.The boy dipped the basket into the river and ran as hard as he could. With the empty basket, he gasped（喘气说）, “See Grandpa? It’s useless!”“So you think it useless?” the old man asked. “Then look at the basket.” To his surprise, the boy found it washed clean of the dirty coal stains and now clean inside and out.“My child, that’s what happens when you read the book. You might not understand or remember everything, but the words will change you inside and out. That is the work of reading in our lives.”8. Why did the man tell the boy to fetch a basket of water？A. The work was too much for himself.B. He intended to train the boy to run faster.C. The work could test how fast t he boy ran.D. He meant to inspire the boy through an example.9. What does the underline word “emulate” in Paragraph 1 most probably mean?A. encourage.B. copy（模仿）C. admire.D. challenge.10. Which of the following words can be used to describe the grandfather?A. Healthy and smart.B. Thoughtful and loving.C. Serious and knowledgeable.D. Wise and diligent.11. What would be the best title for this passage?A. The Power of Reading.B. On Reading BooksC. Old Man and His Grandson.D. A Basket of Water.DOne afternoon I toured an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet view of the art works.A young couple viewing the paintings ahead of me chatted nonstop between themselves. I watched them a moment and decided the wife was doing all the talk. I admired the husband’s patience for putting up with her continuous talk. Distracted by their noise, I moved on.I met with them several times as I moved through the different rooms of art. Each time I heard her constant burst of words, I moved away quickly.I was standing at the counter of the museum gift shop making a purchase when the couple came near to the ex it. Before they left, the man reached into his pocket and pulled out a white object. He extended it into a long stick and then tapped his way into the coatroom to get his wife’s jacket.“He’s a brave man.” The clerk at the counter said, “Most of us would give up if we were blinded at such a young age. During his recovery he made a promise that his life wouldn’t change. So, as before, he and his wife come in whenever there’s a new art show.”“But what does he get out of the art?” I asked, “He can’t see.”“Can’t see? You’re wrong. He sees a lot. More than you or I do.”The clerk said, “His wife describes each painting so he can see it in his head.”I learned something about patience, courage and love that day. I saw the patience of a young wife describing paintings to a person without sight and the courage of a husband who would not allow blindness to change his life. And I saw the love shared by two people as I watched this couple walk away hand in hand.12.

(共15小题；每小题2分，满分30分)ATerra-cotta WarriorsAs the greatest archaeological findings of the 20th century, Terra-cotta Warriors has a really long history. In 246 BC, Qin Shi Huang, later the first Emperor of all China, had begun to prepare for his mausoleum which took 11 years to finish to defend him in the afterlife. There are over 7,000 pottery soldiers, horses, bronze chariots, and even weapons found in it now. Terra-cotta Warriors was listed by UNESCO in 1987 as on e of the world cultural heritages and it has made Xi’an a famous city for tourists. Big Wild Goose PagodaThe Big Wild Goose Pagoda has a history of over 1,300 years and is a typical ancient Chinese building. It is located in the south of Xi’an City. Because Master Xuanzang stored his classics brought from India in the pagoda, it is also a holy place for Buddhists. As a National Key Cultural Relic Preserve, it won the title of an AAAA Tourist Attraction as well.Xi’an Ancient City WallAs one of the lan dmarks of Xi’an, Ancient City Wall still stretches round the old city today, dividing the city into the inner part and the outer part. Ancient City Wall was originally built during the old Tang Dynasty (618 — 907) and then enlargedby Zhu Yuanzhang, Empero r of the Ming Dynasty, thus forming the modern Xi’an City Wall.

I looked around with 15 minutes left, because I had finished and was checking my test.I noticed something very special!Mr. Ward was staring right at one of the kids that seemed to be only halfway done with his test. Every test we took, there was always one guy scrambling at the last minute to finish his test. He would turn the pages and you saw blank spot after blank spot. Sometimes I even saw entire pages that were left blank. Mr. Ward did not take his eyes off this kid. It seemed strange to me. For the rest of the test, Mr. Ward watched that kid as he struggled furiously(猛烈地), tapping papers back and forth and writing furiously and erasing even more furiously. He seemed to use his calculator a lot more than he needed.After the test was finished, Mr. Ward gave his end of the year speech, basically along the lines of good luck and good job. Then I saw him go to the kid he was watching and tell the kid to go into the hall.Mr. Ward walked out of the room and went into the hall silently. He closed the door and from that moment on, I heard about 4 minutes of Mr. Ward shouting at kid.He got his test torn up and a zero for the end of the year exam and also failed for the term and had to take summer school.That was the first and the last time that I had seen Mr. Ward ever yell like that.Obviously the guy had written his answers inside the sleeve of the calculator and every time he was “using his calculator” he was really looking at the formulas and other information he had written inside of the sleeve, which was all in vain because Mr. Ward spotted it a mile away.4. From this passage we know that _________.A.Mr. Ward disliked his studentsB.the student Mr. Ward was staring at wasn’t good at mathematics at allC.the student Mr. Ward was noticing was working at his test quicklyD.the author was trying to help the kid out5.The underlined word “lines” in paragraph 4 refers to _________.A.the math examsB.the summer schoolC.the math papersD.Mr. Ward’s speech6. The student used his calculator again and again because he _________.A.intended to attract Mr. Ward’s attentionB.needed to calculateC.wanted to glance at what he had hidden inside the sleeve of the calculatorD.felt too frightened to use it properly with Mr. Ward staring at him.7. We can infer from this passage that _________.A.Mr. Ward was working as a math teacher for a long time.B.the student was asking the author for help when caught cheating in the exam.C.Mr. Ward regretted not having let the student pass the examD.the students were taking their final-term math examCHealth food is a general term applied to all kinds of food that is considered morehealthy than the types of food sold in supermarkets. For example, whole grains, dried beans, and corn oil are health food. A narrower classification of health food is natural food. This term is used to distinguish between types of the same food. Raw honey is a natural sweetener, while refined sugar is not. Fresh fruit is a natural food, but canned fruit, with sugars and other additives(添加剂), is not. The most exact term of all andthe narrowest classification within health food is organic food, used to describe foodthat has been grown on a particular kind of farm. Fruits and vegetables that are grown in gardens, that are treated only with organic fertilizers, that are not sprayed with poisonous insecticides（杀虫剂）, and that are not refined after harvest, are organic food. Meat, fish, dairy and poultry products from animals that are fed only on organically-grown feed and that are not injected with hormones are organic food.In choosing the type of food you eat, then, you have basically two choices: inorganic, processed food, or organic, unprocessed food. A wise decision should include study of the reason why processed food contains chemicals, some of which are proved to be poisonous and that vitamin content is greatly reduced in processed food.Bread is typically used by health food supporters as an example of a processed food. First, the seeds from which the grain is grown are treated with a chemical which is extremely harmful. Later. The grain is sprayed with a number of very deadly insecticides. After the grain has been made into flour, it is made white with another chemical which is also poisonous. Next, a dough conditioner is added along with a softener. The conditioner and softener are poisons, and in fact, the softener has sickened and killed experimental animals. A very poisonous anti-fungal compound, is added to keep the bread from getting moldy.Other food from the supermarket would show a similar pattern of processing and preserving. You see, we buy our food on the basis of smell, color, and texture, instead of vitamin content, and manufacturers give us what we want, even if it is poisonous. The alternative? Eat health foods, preferably the organic variety.8.What is the passage mainly about?A.Health food.B.The processing of breadC.Processed foodD.Poisons9. What do all of the additives in bread have in common?A. They are all used to keep the bread from getting moldy.B. They are all poisonous.C. They are all organic.D. They have all killed laboratory animals.10. What happens to food when it is processed?A. The basic content remains the same.B. Vitamin is not available after processing.C. The vitamin content increases a bit.D. The vitamin content is greatly reduced.11. We normally buy food on the basis of _________.A. organic varietyB. beautyC. refined contentsD. color and textureDLondoners are great readers. They buy vast numbers of newspapers and magazines and of books --- especially paperbacks, which are still comparatively cheap in spite of ever-increasing rises in the costs of printing. They still continue to buy “proper”books, too, printed on good paper and bound (装订) between hard covers.There are many streets in London containing shops which specialize in book-selling. Perhaps the best known of these is Charring Cross Road in the very heart of London. Here bookshops of all sorts and sizes are to be found, from the celebrated one which boasts of being “the biggest bookshop in the world” to the tiny, dusty little places which seem to have been left over from Dickens’ time. Some of these shops stock, or will obtain, any kind of book, but many of them specialize in second-hand books, in art books, in foreign books, in books on philosophy, politics or any other of the countless subjects about which books may be written. One shop in this area specializes only in books about ballet!Although it may be the most convenient place for Londoners to buy books, Charring Cross Road is not the cheapest. For the really cheap second-hand books, the collector must venture off the beaten track, to Farringdon Road, for example, in the East Central district of London. Here there is nothing so impressive as bookshops. The booksellers come along each morning and pour out their sacks of books onto small hand carts. And the collectors, some professionals and some amateurs, have been waitingfor them. In places like this they can still, occasionally, pick up for a few pence an old one that may be worth many pounds.12.“Londoners are great readers” means that _________.A. Londoners are great because they read a lot.B. There are a great number of readers in London.C. Londoners read a lot.D. Londoners are readers who read only great books.13. According to this passage, Charring Cross Road _________.A. is in the suburbs of LondonB. is the busiest street in LondonC. contains various kinds of shopsD. is famous for its bookshops14. In this passage, what does the underlined part “venture off the beaten track”mean?A. move away from a busy streetB. buy books in a most busy streetC. waste time looking for booksD. take a risk of losing one’s life15. On Farringdon Road, _________.A. you can find fine bookshops for the latest booksB. there are only small bookshops for the second-hand booksC. you can see book sellers selling books on hand-cartsD. the same books as the ones in the bookshops of Charring Cross Road are sold第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
