Question

【题目】 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 （血压）. 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（缓解）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 （伦理的）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 （海马体）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（新皮质），which controls attention and planning.

Answer 1

【答案】

【1】A

【2】D

【3】C

【4】D

【解析】

本文主要讲了研究人员测试了一种能够帮助人们忘掉不好记忆的药片，它是非常有效的。它通过阻止大脑重复储存记忆来达到目的，但同时也引发了一些伦理的担忧；接下来讲了形成记忆与海马体有密切的关系。

【1】

主旨大意题。本文主要讲了研究人员测试了一种能够帮助人们忘掉不好记忆的药片，它是非常有效的，它通过阻止大脑重复储存记忆来达到目的，所以文章主要讲的是一项新的医学发明，故选A。

【2】

细节理解题。根据第二段“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加拿大麦吉尔大学的研究人员已经测试出了一种能帮助你忘掉不好记忆的药片。他们对六十个人进行测试，发现它很有用”可知这个药片能够帮助人们忘掉痛苦的记忆，故选D。

【3】

细节理解题。根据第六段“A11 of us can think of bad events in our lives that were terrible at the time but make us who we are所有人都认为我们生活中的坏事在当时是糟糕的，但它们却让我们每个人成为我们自己”可知经历不好的事情会使我们与众不同。对于B项“The pill can help avoid the mistakes of the past这个药片能够帮助避免过去的错误”根据前句可知应该是坏的事情，而不是这个药片，故选C。

【4】

推理判断题。根据第六段句意这种治疗方式有一些伦理上的担忧，有些人可能会用它来忘记他们应该学习的东西，例如当他们犯了罪时。不好的事情会让我们变得与众不用，会让我们避免过去的错误和“I'm not sure we want to erase those memories我不确定是否我们想要去抹掉这些记忆”可知医务人员也不确定这种药片的影响，故选D。
