15、ng.阅读理解Electrical and computer engineering students Viet Tran and Seth Robertson were looking for an interesting idea for their senior research project. Thats when they came across an experiment done by the Defense Advanced Research Projects Agency in 2012. The experiment was given up after the agen
16、cy was unable to determine its effectiveness (效率) on a large scale.Tran and Robertson decided to challenge themselves and see if they could take the research to the next level and build a fire extinguisher that could be used widely. As with any radical (激进的) idea, they faced a lot of doubt even from
17、 faculty members, many of whom refused to serve as advisors. After all, neither of the students were chemical engineers, so what could they possibly know about creating a fire extinguisher？The students were finally able to persuade Professor Brian Mark to oversee the project and not fail them.The yo
18、ung engineers first tried to put out the fire by placing a subwoofer (超低重音音响) near a flame created using rubbing alcohol. But they soon realized that “music” is not such a good idea. The next option was exposing the fire to 20,000 to 30,000 hertz frequencies. However, with the high frequencies, the
19、flames only grew stronger. The two succeeded when they reduced the frequency to about 30 to 60 hertz. It turns out that at these low frequencies, the sound takes the oxygen away from the flames. With no fuel to keep them going, the fire dies.While it can now put out only small alcoholfueled fires, t
20、he students hope to make it work for other flammable (易燃的) chemicals as well. Also, although Tran and Robertson had just expected the handheld extinguisher to be for home or space use, they now believe it could even work for larger fires. A local fire department has already shown interest in testing
21、 the extinguisher on a structure fire, in the hope of replacing toxic chemicals with clean sound waves.1The experiment mentioned in Paragraph 1 was probably done to _.Alearn how a large fire spreadsBimprove electrical engineeringCshow if sound could put out a fireDhelp students learn chemistry2Which
22、 of the following could be used to put out an alcoholfueled fire?AMusic from a subwoofer.B30 to 60 hertz frequencies.C3,000 to 6,000 hertz frequencies.D20,000 to 30,000 hertz frequencies.3What would Tran and Robertson probably do next?AMake toxic chemicals harmless to put out a fire.BFind out how to
23、 put out a large fire using sound waves.CFind out how to put out a home fire using sound waves.DFind out if sound waves could put out alcoholfueled fires.4The text is developed by _.Agiving typical examplesBfollowing the order of timeCanalyzing a theory and arguing itDcomparing and finding differenc

25、我注意到了一个男孩子性格腼腆，不大合群。我和其他老师共同努力，给予了他更多的关注。最后，他很好地融入这个集体，分享与大家在一起的快乐。1解析：在夏令营的第一天，我注意到(noticed)有个男孩子独自待在大树下。答案：C2解析：他的不自在(discomfort)和害羞使他显得很柔弱很孤独。答案：B3解析：就在那个孩子的附近，一群热切的(eager) 孩子们在玩耍、说笑。答案：D4解析：那个男孩儿好像非常不愿意在这里。短语 other than“除以外” 。答案：A5解析：我被告知要多关注那些被冷落的孩子。leave out“遗漏，省略，删去，未顾及，不考虑” ；feel left out“感觉
26、到被忽略” 。答案：A6解析：所以，我主动向他走过去(approached)，和他攀谈起来。答案：D7解析：in a shaky voice“用颤抖的声音” 。答案：B8解析：他非常不情愿地(unwillingly)回答了我的问题。从本句的这两个空可知，这个男孩子性格腼腆，不善与人交往。答案：B9解析：我平静地让他加入大家的活动，并认识(meet)一些新朋友。答案：D10解析：我可以感觉到(sense)，这种经历使他感到陌生(strange)。答案：A11解析：参见上题解析。答案：C12解析：但是我知道要是逼迫(push)他( 接受)，也不太好。答案：A13解析：(要让他改变)还需要一段时间和
27、更多的努力(efforts)。答案：C14解析：大家都积极参与了。但是，这个男孩儿只是独自坐着，看着(staring) 窗外。答案：D15解析：在那天晚上举行的工作例会上，我向大家表明我对他的关注(concern)。答案：B16解析：我提醒其他老师要对这个男孩多加关注，在他身上尽量(when they could)多花些时间。答案：C17解析：那天待在树下的男孩儿脱掉了衬衫在跳舞，简直是个奇才(wonder)。答案：A18解析：他占据了整个场地跳舞，与大家共享(sharing)美好的时光。答案：D19解析：在那一瞬间，我突然意识到每天奉献一点点是多么容易啊。答案：B20解析：我逢人就讲这个故事
28、，建议大家多关注那些被人冷落的孩子。as often as I can“尽量经常地” 。答案：C.语篇解读：两位电子与计算机工程系的学生发明了用声波灭火的方法。1解析：推理判断题。根据这个实验激发了 Viet Tran 和 Seth Robertson 的兴趣，并最终使他们发明了用声波灭火方法的语境可知，这个实验是关于用声音灭火的。答案：C2解析：细节理解题。根据第三段的“The two succeeded when they reduced the frequency to about 30 to 60 hertz. It turns out that at these low freque
29、ncies, the sound takes the oxygen away from the flames.”可知，利用这个频率的音波可以灭火。答案：B3解析：推理判断题。根据第四段的“Also, although Tran and Robertson had just expected the handheld extinguisher to be for home or space use, they now believe it could even work for larger fires.”可推断，他们接下来会试着去找出用声波灭大火的方法。答案：B4解析：文章结构题。根据文章内容，可知文章是根据事情发生的先后顺序展开的，故选B 项。答案：B
