Grammar and VocabularySection ADirections: After reading the passages below, fill in the blanks to make the passages coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.(A)George Dawson was born in the state of Texas. He was the grandson of slaves. He began working on the family farm when he was four. When he was twelve, he worked 25 a nearby farm to help feed his parents and four younger brothers and sisters. For the next eighty-five years, he held a number of different jobs, most of them involving hard labor.George Dawson lived a happy life 26 ______ conditions were difficult. When he was ten years old, he saw a young African-American man 27 (murder). He would have told people about it, but he said his 28 (big) problem was his inability to read and write.George Dawson kept it a secret that he could not read. But he said he always dreamed that he would learn. Although he had no education, he taught his children 29 (work) hard in school.G eorge Dawson’s life changed in 1996. A man came to his house in Texas, and told him that adult education classes were being taught at a nearby school. So the man who 30 (sign) his name with an “X” for almost one-hundred years went to school.People wondered 31 Mr. Dawson did not go to school earlier. He said he never had the time because of his farm work. And he never knew about adult education programs.George Dawson did all he 32 to learn to read, which influenced students of all ages. He spoke to young people about the importance of learning to read and write.(B)Americans and Arabs are different 33 it comes to their space habits. Arabs would rather have close contact.

In talking with Americans who had lived overseas, he found that many of 35 had been highly uncomfortable 36 ________ culture differences. Such discomfort is usually referred to as culture shock.The problem is that, relatively speaking, Americans live in 37 noncontact culture. Partly, this is a product of our puritan heritage (清教徒文化遗产). Dr. Hall points out that we spend years 38 (teach) our children not to crowd in and lean on us. And in situations 39 we ourselves are forced to stand close to another person on crowded subways, for example, we turn our eyes away, and if actual body contact 40 (involve), tense the muscles on the contact side. Most of us feel very strongly that this is the only proper way to behave.Section BDirections: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That’s a move similar to what a Texas A&M University researchers have 41 for the past five years in a project called “Noah’s Ark.”Noah’s Ark is aimed at collecting eggs, embryos (胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become 42 , Dr. Duane Kraemer, a professor in Texas A&M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to 43 the species in the future.It is estimated that as many as 2,000 species of mammals, birds, reptiles will face extinction in over 100 years. The panda, 44 only to China, is in danger of extinction in the next 25 years.This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to 45 the embryo into a host animal.The entire 46 could take from three to five years to complete.“The nuclear transfer of one species to another is not easy, and the lack of available panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnanc y (怀孕). It takes a long time and it’s difficult, but this could be 47 science if it works. They are certainly not putting any live pandas at risk, so it is 48 the effort,” adds Kraemer, who is one of the leaders of the project at Texas A&M, the first-ever 49 at cloning a dog.“They are trying to do something that’s never been done, and this is ve ry similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly50 their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.It can be hard to decide which food to buy in an American grocery store these days. The information on many products makes 51 claims.The label “organic (有机的)”52 that the United States Department of Agriculture recognized the product was grown under special conditions. The department says foods that meet requirements of it National Organic Programme can use an official label. It shows the words “USDA Organic” inside a(n)53 . USDA organic food does not contain genes that have been 54 changed. The food is grown without chemical treatment against insects or diseases. It is grown without chemical fertilizers. Before a product can be 55 “organic,” a(n)56 visits the farm where the food is produced to make sure the farm meets USDA standards. Organic meat, poultry, eggs and dairy products come from animals that are given no antibiotics (抗生素), must be fed organic food and have 57 to the outdoors.No conclusive 58 shows that organic food is more nutritious than traditionally grown food. And the USDA—even if it proves organic food—doesn’t claim that these products are safer or more nutritious. Organic foods meet the same quality and safety standards as traditional foods. The difference 59 how the food is produced, processed and handled. Some people buy organic food for 60 reasons. Organic food is produced by farmers who 61 the use of renewable resources and the conservation of soil and water to enhance quality for future generations. The prices between most organic food and traditional food products 62 . Higher prices are due to more expensive farming practices and tighter government regulations.The new USDA’s national organic programme for labeling are aimed at enabling consumers to make a(n) 63 choice among the foods they purchase and also include the safeguard of fines for 64 . People who sell or label a product “organic” when they know it does not meet USDA standards can be 65 up to $11,000 for each violation.51. A. unbelievable B. familiar C. different D. flexible52.

A. awarded B. developed C. fined D. sparedSection BDirections: Read the following three passages. Each passage is Followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Indian’s snake charmers are to be retrained as wildlife teachers under a plan to prevent their unique skills and knowledge from being lost. The charmers, who make snakes dance to the sound of flutes (笛子), used to be a traditional feature of Indian life, performing in towns and villages, until they were banned in 1972 to control the trade in snake skins.The government is now considering a plan to train the saperas, as they are known, to visit schools and zoos to tell children about forests and wildlife. There is also a proposal to set up a “dial a snake charmer” service to help householders to deal with unwelcome intruders.“For generations they have been a feature of Indian life but now they can’t earn a living for fear of arrest,” said Behar Dutt, a conservationist behind the plans, “if a policeman doesn’t catch them, animal rights activists report them.”Many snake charmers have continued to work clandestinely since the ban, despite the threat of up to three years in jail. But their trademark cloth-covered baskets, hung from a bamboo pole carried across their shoulders, make them an easy target for police.The fate of Shisha Nath, 56, from Badarpur, a village just outside of Delhi, is typical of practitioners (从业者) of the dying art. “I used to earn enough to support my family and send my children to school,” he said. “Now it’s hard to earn even £1 a day. My children want to be snake charmers. It’s our identity. We love the work. But it’s become impossible.”Next month Dutt’s project to train 30 snake charmers will begin at a snake park in Pune, western India, where experts will enrich their home-grown skills with some formal knowledge.More than the law, though, it is the dishonest attitude of their fellow countrymen that angers many snake charmers.“We’re disturbed all the time but when people want a snake removed from the house, they rush to us,” said Prakash Nath, who was ordered recently to the home of Sonia Gandhi, th e Congress party leader.66. Snake charmers will be retrained as wildlife teachers mainly because ______.A. schools need large numbers of such teachersB. most of them cannot support their familiesC. their performances on the street are bannedD. the government plans to save the dying art67. The purpose of the proposed “dial a snake charmer” telephone service is ______.A. to give performance of snake dancingB. to teach householders how to catch and kill snakesC. to offer cleaning service to wealthy householdersD. to help remove unwanted snakes from the houses68. The word “clandestinely” in paragraph 4 can be best replaced by the word “_____”.A. secretlyB. publiclyC. subconsciouslyD. diligently69. Which of the following statements is NOT true according to the passage?A. Snake charmers can easily be recognized by the police on the street.B. Children of snake charmers would not like to continue their fathers’ job.C. Snake charmers are quite angry with the attitude of their fellow countrymen.D. The animal rights activists take a negative attitude towards snake charmers.(B)We have designed all our bank cards to make your life easier.How to use your NatWest ServicecardAs a Switch card, it lets you pay for all sorts of goods and services, wherever you see the Switch logo.

The purpose of the passage is to show you how to ______.A. play your cards rightB. use your cards abroadC. draw cash with your cardsD. pay for goods with your cards(C)Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve got a thing that sends out energy at tiny chips in everyone’s name tag. The chips send back names, jobs, hobbies, and the time available for meeting-whatever. Making new friends becomes simple.This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source-batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (veryimportant person) section and pays for the bill with the wave of an arm.Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler.RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly,”predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers. Accompanied by how many biscuits.When Marconi invented radio, he thought it would be used for ship-to-shore communication, not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.74. The article is intended to .A. warn people of the possible risks in adopting RFID technologyB. explain the benefits brought about by RFID technologyC. convince people of the uses of RFID technologyD. predict the applications of RFID technology75. We know from the passage that with the help of RFID tags, people .A. will have no trouble getting data about othersB. will have more energy for conversationC. will have more time to make friendsD. won’t feel shy at parties any longer76. Why are some people worried about RFID technology?A. Because children will be tracked by strangers.B. Because market competition will become more fierce.C. Because their private lives will be greatly affected.D. Because customers will be forced to buy more products.77. The last paragraph implies that RFID technology .A. will not be used for such matters as buying milkB. will be widely used, including for buying milkC. will be limited to communication usesD. will probably be used for pop musicSection CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.Too much eating. Too many unhealthy foods. Too many advertisements for food. Too little activity. Different explanations are offered for America’s weight problem — a problem increasingly shared by other countries. Almost one-fifth of American children and teenagers are overweight.Schools have been urged to increase physical education, an important tool for public health. And many have. Yet now comes a study showing an increase in the number of injuries in “phys ed” class. Injuries increased one hundred fifty percent between nineteen ninety-seven and two thousand seven.The study involved injuries treated in hospital emergency departments. Only two percent were serious.The researchers did not try to identify the causes of the increase, but they have some theories. Lara McKenzie from Ohio State University was the lead researcher. She says one possibility is a decrease in the number of school nurses during the period they studied. For example, a two thousand four study showed that the number of school nurses nationally failed to meet federal guidelines. Schools without a nurse on duty may be more likely to send an injured child to a hospital.Another possible reason for more injuries is a change in the traditional idea of physical education. This “New P.E.” expands the kinds of sports that are taught. But activities that some schools offer now, like rock climbing and skateboarding, can also expand the risks, says Cheryl Richardson. She is with the National Association for Sport and Physical Education.Also, she says not all states require P.E. teachers to be specially trained. Untrained teachers could be less likely to recognize unsafe conditions.Cheryl Richardson also points to one of the study’s findings —that injuries are often the result of contact with a person or a structure. This tells her that the teachers were not giving each student enough space to move around safely.Six activities produced seventy percent of all injuries: running, basketball, football, volleyball, soccer and gymnastics.The researchers say larger class sizes are another possible reason for the increase in injuries. Larger classes can mean less supervision. The National Association for Sport and Physical Education says twenty to thirty students in a P.E. class should be the limit.(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS)78.
