1 .<-NARRATOR:-> Listen to part of a lecture in a psychology class.

### 第2段

1 .<-FEMALE PROFESSOR:-> When we think about the past,

2 .when we try to remember the past,

3 .we remember some things better than others.

4 .Why is that? Well, there are a few different explanations.

### 第3段

1 .One explanation is that we remember something better if we already have some previous knowledge about it, some previous understanding of it.

2 .For example, let's say you're going to go to a classical music concert.

3 .If you don't know anything about classical music before you go to the concert,

4 .you probably won't remember many details of the concert later on.

5 .For example, if somebody asks you about the concert a year later,

6 .you probably won't remember what pieces the orchestra played, what order they played them in, and so on....

7 .On the other hand, if you already know a lot about classical music before you go to the concert-

8 .for example, if you've been studying and playing classical music for many years-

9 .it's probably going to be much easier for you to recall the details of the concert later on.

### 第4段

1 .Another explanation is that we remember better when there's something unusual or different about what we're trying to remember.

2 .For example, let's say you're in a class at a university-

3 .a big class, with over a hundred students in it.

4 .A year later, which of those hundred students are you most likely to remember?

5 .Probably the ones who were unusual or different in some way-

6 .maybe a man who was exceptionally tall...or...a woman who was exceptionally intelligent.

7 .The fact that these students were somehow different from the other students will make them easier to remember.
