Question

    Imagine you could remember everything that ever happened to you. The detail（细节）of every book you have ever read. Every moment in class you have ever taken. A perfect memory sounds like a wish come true, doesn't it?

But as the old saying goes, Be careful what you wish for. Believe it or not, there are some people in the world who have near perfect memories of their experiences. They remember almost every detail about almost every day of their lives. People with this ability have a "highly superior autobiographical memory（超级自传体记忆）," or HSAM.

If you are asked this evening to describe the events of your day in as much as detail as possible, you will probably do pretty well. But if I ask you to provide details about what you did on March 3, 2012, do you know what day of the week it was? What did you eat for lunch? Was it cold that day? You would have no idea where to even begin.

A person with HSAM would be able to provide all those details for almost any day of his or her life. In addition to（除了）every great moment they remember, they also remember each time they were embarrassed（难堪）or deeply sad. The negative（消极的）events replay in their minds in equal detail as the great moments. Sometimes，forgetting isn’t such a bad thing.

In fact, for most of us, forgetting is a natural part of how our brains function（运转）. If we don't need to remember something or try to make an effort to remember it, the information fades away（消逝）and is lost. But for those people with HSAM, the problem is that they are unable to forget. All of their experiences, even the most unimportant， remain clear to them all the time.

Research has shown that the brains of people with HSAM do not simply function differently than other brains; their brains are structurally different. By studying the brains of people with HSAM, scientists may be able to find ways of helping others have better memories—not perfect memories with an inability to forget, but better memories.

【解析】

这是一篇说明文。本文主要讲述大多数人都不会记得过去所有的事情，但是拥有超级自传体记忆的人可以记得人生中每一天的细节，包括一些消极的事情。拥有超级自传体记忆的人主要的问题是难以忘记一些不好的回忆。科学家研究这些人的大脑可以帮助记忆力差的人，让他们记忆变好。

1.细节理解题。根据“… You would have no idea where to even begin“”可知“我要求你提供你在2012年3月3日所做的事情的详细信息，你知道这一周中的哪一天吗？你午餐吃了什么？那天天气冷吗”当提出这些问题，“你根本不知道在哪里开始”。而且第四段第一句“A person with HSAM would be able to provide all those details”可知拥有超级自传体记忆的人可以记得细节，而大多数人都记不起过去的很多细节。故选D。

2.细节理解题。根据第四段“In addition to every great moment they remember, they also remember each time they were embarrassed or deeply sad”可知拥有超级自传体记忆的人不仅记得每一个伟大时刻，他们还记得每次他们感到难堪或深感伤心的时候，即好的和不好的细节都记得。故选C。

3.细节理解题。根据第四段最后一句“Sometimes，forgetting isn’t such a bad thing”和第五段第一句 “In fact, for most of us, forgetting is a natural part可知“有时，遗忘并不是一件坏事。事实上，对于我们大多数人来说，遗忘是我们大脑运作的一个自然部分”，所以忘记是重要的和有用的。故选B。

4.标题概括题。第一段最后一句的“A perfect memory sounds like a wish come true, doesn't it?”提出了疑问，而文章后面讲到了记忆力强的好处“大多数人都不会记得过去所有的事情，拥有超级自传体记忆的人可以记得每个细节”；但是文中又提到记忆力强的坏处是“难以忘记那些不愉快不重要的事情”。综合推断出文章标题是说明记忆的不完美性。故选B。
