The most popular way to teach these young children another language is called immersion. Children in immersion programs hear only the new language in the classroom. The children play games, sing songs and talk to one another in the new language. Some experts say immersion programs are the most effective way for young children to learn a language. But there can be a problem when children in the United States begin to learn another language at such an early age. Not many elementary schools(小学) continue the effort as the children get older. Only seven of the fifty states require schools to teach a foreign language to students between the ages of six and twelve. Language experts say it is easier for younger children to learn a language. Still, American schools generally do not begin to teach foreign languages until secondary schools. By then, students are about thirteen years old. American schools face difficult choices about the cost of educational programs. The federal government has increased support for foreign language study in its education law called No Child Left Behind. At the college level, the Modern Language Association says more students than ever are studying foreign languages. The group recently announced its findings for the period from 1998 until 2002. The number of students who studied foreign languages in American colleges and universities increased by seventeen percent. Spanish is the most widely taught language in American colleges and universities. Other popular languages include French, German, Japanese, Chinese and Italian. The Modern Language Association says more languages are being studied now than in the past. It says the largest growth since 1998 has been in the study of American Sign Language, Arabic and biblical Hebrew(希伯来语). The association says about nine percent of college students in the United States study foreign languages. That is the highest level since 1972. 56. The text is mainly about _____. A. foreign language learning in America B. foreign language teaching methods in America C. foreign language teaching in American universities D. foreign language teaching in American high schools 57. The underlined word "immersion" in the first paragraph means "_____". A. put one's head into the water B. pay full attention to one's work C. a teaching method of using only the new language D. a teaching method of hearing two languages 58. What problem do American children face if they learn a foreign language at an early age? A. American children are mostly too poor to learn any foreign languages. B. Their foreign language teachers don't know how to teach them effectively. C. The American government doesn't pay attention to children's foreign language teaching. D. Only a small number of elementary schools continue to teach foreign languages. 59．What is the main idea of the last paragraph? A. Spanish is the most widely taught language in American colleges. B. More and more American college students are learning Chinese now. C. The number of American college students learning foreign languages is increasing. D. A brief introduction to the Modern Language Association in the United States. B TIMETABLE WANT to know what's happening in English teaching and learning? Or, perhaps you want to test your skills?

A. www.cambridgeesolcn.com B. www.51test.com C. www.gre.org D. www.toefl.org C Solar energy for your home is coming. It can help you as a single home owner. It can help the whole country as well. Whether or not solar energy can save your money depends on many things. Where you live is one factor and the type of home you have is another. Things like insulation (绝缘材料), present energy costs, and the type of system you buy are added factors. Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. Sooner or later Mother Nature will say that's all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, like the sun. We won't have to worry about the sun's running out of energy for another several billion years or so. Besides, the sun doesn't offer as many problems as other energy sources. For example, fossil fuel(矿物燃料) adds to already high pollution levels. With solar energy, we will still need sources of energy, but we won't need as much. That means we can cut down on our pollution problems. All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being rationed (限量供应). Solar energy is now in its infancy (初期). It could soon grow to become a major part of our nation's energy supply. 63. What's this passage mainly about? A. Something about solar energy and pollution. B. Solar energy. C. Energy and pollution. D. Energy and money. 64. Solar energy can help us _____. A. escape punishment from nature B. become home owners C. get rid of present energy D. save our precious fuel 65. The sun is an endless source of energy, and it will not run out of energy for _____. A. several million years B. several hundred years C. several billion years D. several thousand years 66. Which of the following statements is TRUE? A. Energy from coal would not pollute our living environment. B. Energy from natural gas would not pollute our living environment. C. Energy from the sun would not pollute our living environment. D. Energy from oil would not pollute our living environment. 67. Solar energy is now in its infancy, _____. A. but in the future it will become an important part of our nation's energy supply B. so we will build more power plants C. and the supply of electricity will be rationed throughout the country D. so we don't need it D Dogs are known for their sense of smell. They can find missing people and things like bombs and illegal (非法的) drugs. Now a study suggests that the animal known as man's best friend can even find bladder（膀胱） cancer. Cancer cells are thought to produce chemicals with unusual smells. Researchers think dogs have the ability to smell these smells, even in very small amounts, in urine（尿）. The sense of smell in dogs is thousands of times better than in humans. The study follows reports of cases where, for example, a dog showed great interest in a growth on the leg of its owner. The mole（黑痣）was later found to be skin cancer. Carolyn Willis led a team of researchers at Amersham Hospital in England. They trained different kinds of dogs for the experiment. The study involved (需要) urine collected from bladder cancer patients, from people with other diseases and from healthy people. Each dog was tested eight times. In each test there were seven samples for the dogs to smell. The dog was supposed to signal the one from a bladder cancer patient by lying down next to it. Two cocker spaniels (小猎犬) were correct fifty-six percent of the time. But the scientists reported an average success rate of forty-one percent. As a group, the study found that the dogs chose the correct sample twenty-two out of fifty-four times. That is almost three times more often than would be expected by chance alone. The British Medical Journal published the research. In all, thirty-six bladder cancer patients and one hundred and eight other people took part. During training, all the dogs reportedly even identified (识别) a cancer in a person who had tested healthy before the study. Doctors found a growth on the person's right kidney(肾). Carolyn Willis says dogs could help scientists identify the compounds produced by bladder cancer. That information could then be used to develop machines to test for the chemicals. Now, doctors must remove tissue（组织） from the bladder to test for cancer. The team also plans to use dogs to help identify markers for other kinds of cancer. 68. What does the underlined word "it" (in Paragraph 3) refer to? A. The dog. B. A patient. C. The sample. D. The test. 69. The best title for this passage might be _____. A. Study Says Dogs Can Smell Cancer B. Why Dogs Can Smell Cancer C. A Study on Dogs'Special Ability D. A Study on Bladder Cancer 70. Dogs can smell cancer because _____. A. they can smell faster than man B. their sense of smell is very sensitive C. they lie down next to patients D. patients give off special odors 71. What can we conclude from the last paragraph? A. Dogs can only smell bladder cancer. B. Dogs have a good knowledge of cancer. C. Scientists might invent some equipment to test cancer. D. Cancer doesn't have any sign in the beginning. E After almost 30 years of arguing that a black hole swallows up everything that falls into it, British astrophysicist (天体物理学家) Stephen Hawking moved backward last week. The world-famous writer of "Brief History of Time" said he and other scientists had got it wrong. "I've been thinking about this problem for the last 30 years, and I think I now have the answer to it," said Hawking. "A black hole only appears to form but later opens up and set free information about what fell inside. So we can be sure of the past and can predict the future." The findings could help solve the "black hole information paradox（似是而非的观点）", an important puzzle in modern physics. A black hole is an area in space where matter is under such pressure that even light can not escape from its gravitational pull(引力). But, exactly what happens there has long puzzled scientists. Black holes occur when a powerful star burns up its nuclear fuel and gravity forces it to break down in on itself. The great weight of the star's outer layers moves in towards its center. The force of gravity keeps nearly all light from escaping and nothing inside can be seen from the outside. The star actually disappears from the universe into a point of infinite density（高密度）. That is a place where the laws of general relativity that govern space and time break down. Hawking has devoted most of his life to studying these questions. At the beginning, cosmologists believed the holes were like a "universal vacuum (真空) cleaner", sucking up everything in their path. Hawking revolutionized the study of black holes when he proved, in 1976 that, under the strange rules of quantum physics（量子物理）, when black holes form they send out energy and lose mass in the process. In thinking up this so-called "Hawking radiation", the Cambridge mathematician also created one of the biggest puzzles in physics. These particles (粒子), he said, contained no information about what has been occurring inside the black hole, or how it formed. Under his theory, once the black hole disappears, all the information within it is lost. 72. What's the importance of Hawking's new findings? A. They could help solve the puzzle about black holes. B. They has solved the mystery of "black holes". C. We can now know what is going on inside "black holes". D. Scientists have already predicted the future of "black holes" now. 73. What's the meaning of the underlined word "cosmologist" (in Paragraph 9)? A. A person who studies the universe and its origin and development. B. A person who studies the stars and their development. C. A person who travels in a spacecraft.] D. A person who studies the position of the stars and the movements of the planets. 74. Which of the following is TRUE? A. Hawking has now studied black holes for more than 40 years. B. During the course of the black hole's formingthe enormous weight of the star's center moves into the outer layers. C. Almost nothing can escape from the gravitational pull of the black hole. D. Scientists have been thinking the black hole contains no information. 75. What would be the best title for the passage? A. The Formation of the Black Hole B. Black Hole Information Paradox C. Black Hole Mystery D.

In my opinion, the classroom is a place for students to gain knowledge. Therefore quietness is badly needed for us to learn our lessons. But recently some students bring their mobile phones to the classroom and we often hear the ring of mobile phones. Some of them even waste precious time in class typing short messages on the mobile phone. To keep the classroom quiet, those with mobile phones should not talk on the phone or send short messages. They should turn them off. We are supposed to concentrate on our studies. Yours sincerely, 听力材料 (Text 1) M: Someone told me Ann's going to become a manager in her father's company. W: She isn't, is she? She's so young. And she still has a lot to learn, doesn't she? M: She sure does, but I guess her father doesn't think so. (Text 2) M: Well done! The job is well done.

I thought I'd get better, but I feel worse than before. W: What seems to be the problem? M: Well, the doctor said it was just a bad cold. He gave me some medicine and told me to take it three times a day after eating, but it doesn't seem to help. W: Listen, forget about that medicine! Just drink some of my mum's tea and you'll be up and dancing around in no time. M: Dancing around in no time, right? Well, I guess nothing else seems to be doing the job. W: I'll come to your place at 7:30. See you then. (Text 7) W: Hello. This is the emergency 911 operator. M: Help, help! W: Please calm down and explain exactly what is happening. M: Calm down!

(Text 10) Brain and Kevin are twin brothers. They are also nearly the same height and weight: tall and slim. They even sound the same when they speak. They each have red hair that, at that time, they kept cut short in the same style. Few years ago they both decided to teach English at the same college in China. By strange luck, they taught the same course to students in the same grade. Of course, they each had their own class to teach! One April Fool's day they decided to play a trick on their students. So they wore each other's favorite clothes and taught each other's class. Most of the students never realized what had happened, but a few did manage to figure it out. These students tried not to laugh aloud and didn't bother to take notes. That was their reward for paying attention and being so clever. Still, all the students who were fooled thought it was really funny too! 部分解析 [语法和词汇知识] 21. D。考查冠词。be in danger of为固定短语，意为“有……危险的”。 22. D。考查时态。题干中有since，故此处用现在完成时。 23. D。考查非谓语动词。此处应用不定式的主动形式表示被动意义。 24. A。考查副词。draw near表示“(春节)即将到来”，而nearly意为“几乎”。 25. C。 考查短语动词。hold out for意为“坚持要……”。 26. D。考查情态动词。shall用于第二、三人称, 表示命令、警告等。 29. D。考查定语从句。此处as是关系代词，引导非限制性定语从句，且在从句中做主语。which引导非限制性定语从句时，不能置于句首。 30. C。考查时态。根据语境可知，Alice过去打篮球和网球，但现在已放弃，故此空用一般过去时。 31. D。考查动词短语。die away表示“（风、声音等）渐息，渐弱”。 32. D。考查非谓语动词。过去分词短语作原因状语，相当于原因状语从句Because he was left in the care of his grandmother. 33. C。考查交际用语。that depends表示“视情况而定”。 35. A。考查名词性从句。 第一空用what引导主语从句；第二空用where引导宾语从句。 [完形填空] 36. D。根据语境可知从句与主句之间是因果关系，故选D项。for引导原因状语从句通常不放在句首。 37. C。从前一句old一词以及下文的overcrowded可知narrow为最佳选项。 38. D。因上文有overcrowded，下文有overflowed into the road, 故可知本题答案应为D项。 40. B。causing danger to sb. 意为“对某人造成危险”，其余三项与句意不符。 41. A。根据本句句意可知，危险来自过往的车辆，所以正确答案为A项。 42. B。从本句结构可知此处需要一个关系代词来引导非限制性定语从句，且先行词指物，故B项正确。 43. A。司机们不停地按喇叭，“说服”人们让路。 44. B。in the / one's way 是“挡路”的意思；get out of one's way是“让开路” 的意思。 45. C。由于此空在第二段的首句(起着主题句的作用)，而且第二段描述的是丰富多彩的市井画卷，所以应选C项。 46. B。根据语境，农民拿到市场上的货物应当是出售的，因此应选B项。 47.
