1、The little girl trembled when she saw a big dog. 【單選題】

A.ran

B.cried

C.shook

D.wept

正確答案:C

答案解析:tremble和shake同義，顫抖、發(fā)抖；run:跑、奔、逃跑；cry:喊叫、哭喊；weep：痛哭、哭泣、悲嘆。

2、While we don\'t agree, we continue to be friends.【單選題】

A.Whoever

B.Where

C.Although

D.Whatever

正確答案:C

答案解析:題干大意：雖然我們意見不同，但是我們?nèi)匀皇桥笥?。畫線詞while引起的是一個讓步從句，所起的作用是跟although一樣的。whoever：無論任何人。where：哪里。如：Where are you from? 你從哪里來？whatever：無論什么。

3、Singing Alarms Could Save the BlindIf you cannot see, you may not be able to find your way out of a burning building ａｎｄ　that could be fatal. A company in Leeds could change all that with directional sound alarms capable of guiding you to the exit. Sound Alert, a company run by the University of Leeds, is installing the alarms in a residential home fｏｒblind people in Sommerｓｅｔａｎｄ　a resource centre fｏｒthe blind in Columbia. The alarms produce a wide range of frequencies that enable the brain to determine where the sound is coming from. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be heard by humans. "It\'s a burst of white noise that people say sounds like static on the radio," she says. "Its life-saving potential is great."She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large smoke-filled room. It took them nearly four minutes to find the doｏｒwithout a sound alarm, but only 15 seconds with one. Withington studies how the brain ______ sounds at the university. She says that the source of a wide bａｎｄ　of frequencies can be pinpointed more easily than the source of a narrow band. Alarms basedon the same concept have already been installed on emergency vehicles. The alarms will also include rising ｏｒfalling frequencies to indicate whether people should go up ｏｒdown stairs. They were developed with the aid of a large grant from British Nuclear Fuels. 【單選題】

A.processes

B.produces

C.possesses

D.proceeds

正確答案:A

答案解析:句子主語是the brain，應(yīng)和“處理”構(gòu)成主謂關(guān)系，其他動詞均不合適。所以選擇A。

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 ______ 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 (機械響應(yīng)性聚合物) which is about to break, it produce 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 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. 【單選題】

A.throw

B.prevent

C.create

D.keep

正確答案:B

答案解析:原文中用also may help，說明應(yīng)填與上文prevent相似的詞句。throw：投擲；create：創(chuàng)造；keep：保持，都與之不符，所以是prevent。

5、There is always excitement at the Olympic Games when an athlete breaks a record.【單選題】

A.beats

B.maintains

C.matches

D.tries

正確答案:A

答案解析:運動員在奧運會上打破記錄時總讓人興奮。本題有一定難度，考查的是引申意義，beat的基本意義是“擊打”，引申意義有“打破記錄”的意思，和break是近義詞，其他選項都是常用詞匯，和答案意義差異大，最佳答案是A。
