3.Ever tried taking smart drugs to perform better in exams?They certainly work.Before last summer's exam,a few of my mates,merely out of curiosity,took a considerable amount of Modafinil,a drug normally used for narcolepsy(嗜眠發(fā)作癥).Guess what?While I was feeling sleepy,bored by revision,my mates were more focused.
Modafinil is a smart drug that gives a user a feeling of staying awake for hours.It also sharpens the mind,improves memory and helps problem-solving.
But it does more than just keeping you awake.It disturbs your mental system,making you desperate to do what you are doing.You just don't want to do anything else but revise all the time non-stop.
A recent study discovers that healthy people use smart drugs,like Modafinil,to get down to and complete tasks they have been putting off,because these tasks seem more enjoyable when taking these drugs.This might sound like what a stressed student desires.However,the pills have a range of side-effects.
"At present no evidence shows that these drugs are safe in healthy people,"as a medical expert puts it,"Ordering online,though easy,is a dangerous way to obtain drugs.You never know what you're actually purchasing."
In my experience,Modafinil changes people's behavior too.Over those weeks my friends   became different people--in turn aggressive,cold.Even eating became"a waste of time"and so did conversation.
A BBC survey found that of those who had tried smart drugs before,92% would do so again.My friends say they'd happily do so without considering the practice a form of cheating.
I admit I was curious-but not enough to try it.Seeing the strange behavior of other users,I feel a little bit upset and scary.Modafinil may promise to change your grades,but it might also change the way you act.Don't say you haven't been warned!

分析 本文屬于說(shuō)明文閱讀,作者通過(guò)這篇文章主要向我們敘述了Modafinil這種藥的藥效,有些要考試的人在吃了以后特別愿意復(fù)習(xí),非常精神不愿意停止學(xué)習(xí),并且能夠提高自己的成績(jī),但是它也有副作用,長(zhǎng)期服用會(huì)起依賴的作用,最后表明作者的觀點(diǎn)不贊成吃這種藥.

解答 31.B.細(xì)節(jié)理解題.根據(jù)文章第一段Ever tried taking smart drugs to perform better in exams,可知大部分學(xué)生選擇去吃這種藥是為了在考試中表現(xiàn)得更好,得到一個(gè)更好的成績(jī),故選B.
32.D.推理判斷題.根據(jù)文章倒數(shù)第二段"A BBC survey found that of those who had tried smart drugs before,92% would do so again",凡是服用過(guò)這種藥物的人絕大部分會(huì)繼續(xù)服用,可推測(cè)這種藥物會(huì)使人上癮.故選D.
33.A.細(xì)節(jié)理解題.根據(jù)文章最后一段"Seeing the strange behavior of other users,I feel a little bit upset and scary"作者對(duì)于其他使用者的表現(xiàn)感到有點(diǎn)沮喪和恐懼.可判斷作者對(duì)這種藥物的作用是擔(dān)憂的,故選A.
34.D.細(xì)節(jié)理解題.根據(jù)文章第五段"At present no evidence shows that these drugs are safe in healthy people,可知現(xiàn)在還沒(méi)有證明這種藥是安全的,故選D.
35.D.細(xì)節(jié)理解題.根據(jù)文章第一段Ever tried taking smart drugs to perform better in exams?可知大部分人選擇去吃這種藥是為了在考試中表現(xiàn)得更好,因此可知這篇文章是寫給學(xué)生的;故選D.

點(diǎn)評(píng) 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí),要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷.
