Question

閱讀理解 　　Not all memories are sweet．Some people spend all their lives trying to forget bad experiences．Violence and traffic accidents can leave people with terrible physical and emotional scars．Often they relive(重新體驗)these experiences in nightmares． 　　Now American researchers think they are close to developing a pill, which will help people forget bad memories．The pill is designed to be taken immediately after a frightening experience．They hope it might reduce, or possibly erase(抹去)the effect of painful memories． 　　In November, experts tested a drug on people in the US and France．The drug stops the body releasing chemicals that fix memories in the brain．So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased． 　　The research has caused a great deal of argument．Some think it is a bad idea, while others support it．Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war． 　　They say that there are many people who suffer from terrible memories．“Some memories can ruin people’s life．They come back to you when you don’t want to have them in a daydream or nightmare．They usually come with very painful emotions, ” said Roger Pitman, a professor of psychiatry(精神病學(xué))at Harvard Medical School．“This could relieve a lot of that suffering．” 　　But those who are against the research say that changing memories is very dangerous because memories give us our identity(特質(zhì))．They also help us all avoid the mistakes of the past．“All of us can think of bad events in our lives that were horrible at the time but make us who we are．I’m not sure we’d want to wipe those memories out, ”said Rebecca Dresser, a medical ethicist(倫理學(xué)家)． 　　Some people fear that although the drug would first be used in only very serious cases, it would become more and more common．“People always have the ability to misuse science, ”said Joseph LeDoux, a New York University memory researcher．“All we want to do is to help people have better control of memories．” (1) What’s the main idea of the text?

Answer 1

答案：1．D;2．B;3．A;4．C;
解析：

(1)	A項表示的是短文第一段的中心；B項表示的是第二、三段的中心。整篇文章的中心是：“忘憂藥”的研制引起了各方人士的爭論。
(2)	根據(jù)第四段所表述的內(nèi)容：這項研究已經(jīng)引起了激烈的爭論，有人說“這”不是個好主意。由此可判斷“it”指的是“the research into the drug”。
(3)	歸納第四、第五段的意義，可知支持者的觀點可概括為B、C、D三項。A項“這種藥能抹去過去所有的記憶”與短文的意義不符，更不用說是支持者的觀點了。
(4)	根據(jù)倒數(shù)第二段所表述的意義，A、B、D三項是反對者的觀點。C項只是文章中所表述的一個現(xiàn)象，并不是他們的觀點。
