1、A Bad IdeaThink you can walk, drive, take phone calls, e - mail ａｎｄ　listen to music at the same time 7 Well, New York\'s new law says you can\'t. ａｎｄ　you\'ll be fined $ 100 if you do so on a New York city street. The law went into force last month, following research ａｎｄ　a shocking number of accidents that involved people using electronic gadgets (小巧機(jī)械) when crossing the street.Who\'s to blame? Scientists say that our multitasking (多任務(wù)處理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神經(jīng)科學(xué)家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. Aｇｒｏｕｐof 18 to 21 years old ａｎｄ　aｇｒｏｕｐof 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The youngerｇｒｏｕｐdid 10 percent better when not interrupted. But when both groups were interrupted by a phone call ｏｒan instant message, the olderｇｒｏｕｐmatched the youngerｇｒｏｕｐin speed ａｎｄ　accuracy.It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $ 650 billion a year. _____. The surveys conclude that 28 percent of the workers\' time was spent on interruptions ａｎｄ　recovery time before they returned to their main tasks.【單選題】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The youngerｇｒｏｕｐdid 10 percent better when not interrupted.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任務(wù)處理) abilities are limited.

F.ａｎｄ　you\'ll be fined $ 100 if you do so on a New York city street.

正確答案:B

答案解析:本題有一定的難度，需要認(rèn)真閱讀文章，理解好句意。可用排除法和代入法。本題的下文談到了對（辦公室）職工做的一次調(diào)查，涉及具體內(nèi)容，所以可以推斷此處應(yīng)該是概括性的句子，來引導(dǎo)下文，而且和職工調(diào)查有關(guān)，回來看選項(xiàng)，把B代入文中，符合邏輯，答案是B。

2、In the process, the light energy converts to heat energy.【單選題】

A.reduces

B.changes

C.leaves

D.drops

正確答案:B

答案解析:在這個過程中，光能轉(zhuǎn)化成熱能。本題難度不大，converts指“轉(zhuǎn)變”，通常與to或者into搭配，和changes“變化”是近義詞，其他三項(xiàng)都是常用詞，和答案意義差異較大，干擾性不強(qiáng)。

3、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 colｏｒ- changing material. It will turn red before a structure collapses ｏｒfalls apart.The secret _____ the colｏｒ- changing material is a particular type of molecule (分子). A molecule is aｇｒｏｕｐof atoms (原子) held together by chemical bonds. Molecules come in 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 colｏｒ- changing molecule called a mechanophore (機(jī)械響應(yīng)性聚合物) is about to break, it produces a color. 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 colｏｒ- changing polymers in their lab. The test results proved encouraging.There is a way to get rid of the red colｏｒlight. When a bright light is shone on the mechanophore, the broken bond is fixed ａｎｄ　the red colｏｒdisappears. Thus "self - healing" may be a problem fｏｒengineers. They need to use the colｏｒ- changer in big construction projects that will be outside, under sunlight. ａｎｄ　sunlight will make the mechanophore\'s warning system useless.Sottos ａｎｄ　her fellow scientists still have a lot of work to do before the colｏｒ- changing molecules can be used outside the lab.【單選題】

A.on

B.behind

C.under

D.down

正確答案:B

答案解析:本題有一定難度，干擾項(xiàng)干擾較大，考查介詞behind的用法，文章此處是說，“材料顏色可以變化其背后的秘密是……”，只有behind可以表示“背后的”意思，答案是B。

4、I was shocked when I saw the size of the telephone bill.【單選題】

A.excited

B.angry

C.lost

D.surprised

正確答案:D

答案解析:當(dāng)看到電話賬單的長度時我很震驚。本題難度不大，shocked指“震驚的”，和surprised“吃驚的”是近義詞，B項(xiàng)“生氣的”有一定的干擾性，其他干擾不大，最佳答案是D。

5、Science Fiction1 Amongst the most popular books being written today are those that are usually classified asscience fiction. Hundreds of titles are published every year ａｎｄ　are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories. 2 It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some forms of ideal society, a theme that is still often found in modern stories. 3 Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verve ａｎｄ　H. G Wells, to mention just two well known authors, have been translated into many languages. 4 Modern science fiction writers don\'t write about men from Mars ｏｒspace adventure stories. They are more interested in predicting the results of technical developments on society ａｎｄ　the human mind; ｏｒin imagining future worlds that are a reflection of the world that we live in now. Because of this their writing has obvious political undertones (涵義). 5 In an age where science fact frequently overtakes (超過) science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology. Books written by J.Verne are____. 【單選題】

A.concerned with the problems that we will have to solve in the future

B.reading books of science fiction

C.political implication

D.a recurrent theme

E.read worldwide

F.translated into many languages

正確答案:E

答案解析:本題答案的依據(jù)是在第3段的最后一句，文章說著名科幻小說家Jules Verne的書被翻譯成了多種語言，世界上許多國家的人都能讀到他的書，故選E。
