Question

【題目】 How about forgetting bad memories?

Can we forget bad memories? Someone might tell you that time is the only “cure”. But this might be not true.

Researchers at Canada's McGill University have tested a pill that can help you forget bad memories. They tested it on 60 people and found it to be useful.

All 60 people had experienced painful romantic relationships and wanted to forget them. In the study, they were asked to write about these bad memories. Then, they took a pill that is usually used to treat high blood pressure （血壓）. They then recalled their bad memories by reading what they wrote earlier. In the end, they talked about their feelings, saying that they were finally able to forget their bad experiences.

Dr. Alain Brunet, who led the study, believes that the pill can ease（緩解）the pain that bad memories bring. People can take it after bad things happen to them.

How did the pill do this? In fact, your memories change all the time. They’re like papers on your computer. Every time you recall and "open” the papers, you might happen to make some changes and "save" them. Researchers believe that the pill can stop something in the brain from "re-saving" these memories. This means some details of the memory are lost.

However, there are some ethical （倫理的）worries about this treatment. Some people might use it to forget things that they should be learning from, such as when they did a crime.

A11 of us can think of bad events in our lives that were terrible at the time but make us who we are. They also help us all avoid the mistakes of the past. I'm not sure we want to erase those memories, said Rebecca Dresser, a medical ethicist.

How do we form memories?

The part of our brain known as the hippocampus （海馬體）is important for forming new memories. Scientists found it after studying a patient named Henry Molaison in the 1950s. After Molaison's hippocampus got hurt during an operation, he couldn't store new memories. But he could remember memories from before the operation. This means long-term memories are stored outside the hippocampus. Scientists believe they are stored in the neocortex（新皮質(zhì)），which controls attention and planning.

【解析】

本文主要講了研究人員測(cè)試了一種能夠幫助人們忘掉不好記憶的藥片，它是非常有效的。它通過阻止大腦重復(fù)儲(chǔ)存記憶來達(dá)到目的，但同時(shí)也引發(fā)了一些倫理的擔(dān)憂；接下來講了形成記憶與海馬體有密切的關(guān)系。

【1】

主旨大意題。本文主要講了研究人員測(cè)試了一種能夠幫助人們忘掉不好記憶的藥片，它是非常有效的，它通過阻止大腦重復(fù)儲(chǔ)存記憶來達(dá)到目的，所以文章主要講的是一項(xiàng)新的醫(yī)學(xué)發(fā)明，故選A。

【2】

細(xì)節(jié)理解題。根據(jù)第二段“Researchers at Canada's McGill University have tested a pill that can help you forget bad memories. They tested it on 60 people and found it to be useful加拿大麥吉爾大學(xué)的研究人員已經(jīng)測(cè)試出了一種能幫助你忘掉不好記憶的藥片。他們對(duì)六十個(gè)人進(jìn)行測(cè)試，發(fā)現(xiàn)它很有用”可知這個(gè)藥片能夠幫助人們忘掉痛苦的記憶，故選D。

【3】

細(xì)節(jié)理解題。根據(jù)第六段“A11 of us can think of bad events in our lives that were terrible at the time but make us who we are所有人都認(rèn)為我們生活中的壞事在當(dāng)時(shí)是糟糕的，但它們卻讓我們每個(gè)人成為我們自己”可知經(jīng)歷不好的事情會(huì)使我們與眾不同。對(duì)于B項(xiàng)“The pill can help avoid the mistakes of the past這個(gè)藥片能夠幫助避免過去的錯(cuò)誤”根據(jù)前句可知應(yīng)該是壞的事情，而不是這個(gè)藥片，故選C。

【4】

推理判斷題。根據(jù)第六段句意這種治療方式有一些倫理上的擔(dān)憂，有些人可能會(huì)用它來忘記他們應(yīng)該學(xué)習(xí)的東西，例如當(dāng)他們犯了罪時(shí)。不好的事情會(huì)讓我們變得與眾不用，會(huì)讓我們避免過去的錯(cuò)誤和“I'm not sure we want to erase those memories我不確定是否我們想要去抹掉這些記憶”可知醫(yī)務(wù)人員也不確定這種藥片的影響，故選D。
