1、Arctic MeltEarth\'s North ａｎｄ　South Poles are famous fｏｒbeing cold ａｎｄ　icy. Last year, however, the amount of ice in the Arctic Ocean fell to a record low. Normally, ice builds in Arctic waters around the North Pole each winter ａｎｄ　shrinks during the summer. But fｏｒmany years, the amount of ice left by the end of summer has been declining. Since 1979, each decade has seen an 11. 4 percent ｄｒｅｐin end of summer ice cover. Between 1981 ａｎｄ　2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner. Last summer, Arctic sea ice reached its skimpiest levels yet. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. ａｎｄ　it\'s a very large 23 percent below the previous record low, which was ｓｅｔjust 2 years ago. This continuing trend has scientists concerned. There may be several reasons fｏｒthe ice melt, says Jinlun Zhang, an oceanographer at the University of Washington at Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice ａｎｄ　open water. Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water ａｎｄ　the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.5℃ warmer than average ａｎｄ　1.5℃ warmer than the previous record high. With both air ａｎｄ　water getting warmer, the ice is melting from both above ａｎｄ　below. In some parts of the Beaufort Sea, north of Alaska ａｎｄ　western Canada, ice that measured 3. 3 meters thick at the beginning of the summer measured just 50 centimeters by season\'s end. The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist at the U. S. Army Cold Regions Research ａｎｄ　Engineering Laboratory in Hanover, N. H. Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover. Which of the following is closest in meaning to the word "build" in the first sentence of the second paragraph?【单选题】

A.construct

B.extend

C.create

D.expand

正确答案:D

答案解析:本句意思为“每年冬天北极附近的北冰洋开始结冰”，build为“结冰”的意思，expand有“容积扩张”的意思，所以与build相符；而construct为“修筑、建筑”的意思，所以不能选。

2、A special educationVideodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, ｏｒsocializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one ｏｒmore of the following ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, ｏｒother health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, ａｎｄ　indefatigable (孜孜不倦) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, ａｎｄ　designers can assure absolute consistency within a program. Most important, according to special educatｏｒWilliam Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism fｏｒchildren who need graphic representations."Healey explained that deaf ａｎｄ　mentally retarded children especially have difficulty grasping figurative language ａｎｄ　higher-ｏｒｃｅｒlanguage concepts. He believes that fｏｒspecial education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken fｏｒgranted by non-handicapped persons. Complex figurative language forms such as idioms ａｎｄ　metaphors come most readily to mind as being difficult fｏｒhandicapped learners. The special education mentioned in the text is mainly concerned with____. 【单选题】

A.genius students from day-care centers to colleges

B.students who are fond of computer video games

C.teachers of language in the University of Arizona

D.students who are either mentally ｏｒphysically disabled

正确答案:D

答案解析:由文章第1段“Handicapped students require special education because they are. . . ”可知，文中提及的特殊教育针对的是有智力和身体残疾的学生们，故选D。

3、Cell Phones1. Believe it ｏｒnot, cell phones have been around fｏｒover a quarter of a century. The first commercial cell phone system was developed by the Japanese in 1979, but cell phones have changed a lot since that time. The early cell phones were big ａｎｄ　heavy but they have developed into small ａｎｄ　light palm sized models. There are huge developments in their functions, too. We have had call forwarding, text messaging, answering services ａｎｄ　hands - free use fｏｒyears, but now there are new facilities, such as instant access to the Internet ａｎｄ　receiving ａｎｄ　sending photos.2. Cell phones have become very common in our lives. Recent statistics suggest one in three people on the planet now have cell phone, ａｎｄ　most of them say they couldn\'t live without one, Cell phones are used in every area of our lives ａｎｄ　have become a necessary tool, used fｏｒessential arrangements, social contact ａｎｄ　business. It easier to call fｏｒhelp on the highway. It possible to keep in touch with people "on the move" when people are traveling.3. Cell phones have made communication easier ａｎｄ　have reduced the need fｏｒfamily arguments f We can use cell phones to let our family know we\'ll be late ｏｒif there\'s a sudden change of plan ｏｒan emergency. Cell phones have eased the worries of millions of parents when their teenagers are out late. They can now contact their children at any time.4. This does not mean that cell phones are all good news. Cell phones have brought with them a number of new headaches fｏｒtheir owners. It costs a lot to replace stolen phones, It is becoming a frequent occurrence, ａｎｄ　have you ever seen such a huge phone bills? More serious, however, Cell phones bring the potential health problem. There are fears that radiation from the phones may cause brain tumｏｒ肿瘤). This may be a time bomb waiting to happen to younger people who have grown up with cell phones. They simply can\'t live without cell phones!Paragraph 2 ______【单选题】

A.Cell phones ａｎｄ　the family

B.Commercial cell phone systems

C.Cell phones in everyday life

D.Cell phones fｏｒteenagers

E.History of cell phones

F.Problems with cell phones

正确答案:E

答案解析:本题有一定的难度，需要有一定的归纳概括能力。可以发现，文章第一段主要手机的发展历史做了简单论述，E项History of cell phone简单概括了本段内容，是答案。

4、Seeing Red Means Danger AheadThe colｏｒred often means danger ａｎｄ　by paying attention, accidents can be prevented. In the future, the colｏｒred also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports ｏｒother kinds of materials could one day contain a colｏｒswitching material. It will turn red before a structure collapses ｏｒfalls apart. The secret behind the colｏｒswitching material is a particular type of molecule. A molecule is aｇｒｏｕｐof atoms held together by chemical bonds. Molecules come at all shapes ａｎｄ　sizes, ａｎｄ　make up everything. You can see, touch ｏｒfeel. How a molecule behaves depends on what kinds of atoms it contains, ａｎｄ　how they\'re held together. When a polymer (聚合物) containing a colｏｒswitching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a ______. When a polymer with mechanophore molecules becomes "injured" ｏｒweak, one of the mechanophore bonds breaks ａｎｄ　the material turns red. "It\'s a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos ａｎｄ　her team tested the colｏｒswitching polymers in their lab. The test results proved encouraging. There is a way to get rid of the colｏｒlight when a bright light is shone on the mechanophore. The broken bond is fixed ａｎｄ　the red colｏｒdisappears. This "self-healing" may be a problem fｏｒengineers. They need to use the colｏｒchanger in big construction projects that will be outside in sunlight. ａｎｄ　sunlight will make the mechanophore\'s warming system useless. Sottos ａｎｄ　her fellow scientists still have a lot of work to do before the colｏｒswitching molecules can be used outside the lab. 【单选题】

A.color

B.trouble

C.what

D.where

正确答案:A

答案解析:前文一直提示分子变红色，所以在此情景下，选颜色是符合全文主题的。

5、English ａｎｄ　English Community1 There is no doubt that English is a useful language. The people who speak English today make up the largest speech community in the world with the exception of speakers of Chinese. 2 A speech community is similar to other kinds of communities. The people who make up the community share a common language. Often they live side by side, as they do in a neighborhood, a village, ｏｒa city. More often they form a whole country. National boundaries, however, are not always the same as the boundaries of a speech community. A speech community is anyｇｒｏｕｐof people who speak the same language no matter where they happen to live. 3 We may say that anyone who speaks English belongs to the English speech community. Fｏｒconvenience, we may divide the speakers into two groups: one in which the speakers use English as their native language, the other in which the speakers learn English as a second language fｏｒthe purpose of education, commerce, ａｎｄ　so on. 4 Learning a second language extends one\'s vision ａｎｄ　expands the mind. The history ａｎｄ　literature of a second language record the real ａｎｄ　fictional lives of people ａｎｄ　their culture; a knowledge of them adds to our ability to understａｎｄ　ａｎｄ　to feel as they feel. Learning English as asecond language provides another means of communication through which the window of the entire English speech community becomes a part of our heritage. Paragraph 2____【单选题】

A.Threat Posed by English

B.Definition ofa Speech Community

C.Benefits ofLeaming a Second Language

D.Advantages of Learning Chinese

E.Two Groups ofthe English Speech Community

F.A Widely Used Language

正确答案:B

答案解析:文章第2段主要讲的是什么是a speech community，即a speech community的定义。
