听力原文：M: One of the most common questions we ask about people's behavior. is why. Why d

id she say this？ Why did he do that？ Sometimes the reason is obvious, for example, someone is driving down the street, the light turns red, and they stop, why？

W: Because they have to, legally I mean.

M: Exactly! In this case the reason is obvious, so usually we don't question it. But when the reason is not so obvious and especially when the behavior. could have negative consequences, we'll more likely to feel a need to explain the causes of the behavior. Social psychologists have a term for this, for the process of explaining the causes of the behavior, it's called "causal attribution". And one theory suggests, there's a pattern in the way we go about attributing causes to people's behavior. According to this theory, there are two categories of reasons: internal factors and external factors. Again, Lisa, say you're driving down the road and all of a sudden some guy turns into the lane right in front of you, and you have to slam on your brakes to avoid an accident. How do you react？

W: I'll probably get very angry.

M: Because...

W: Well, he's not paying attention, he's a bad driver.

M: So you automatically attribute, the driver's behavior. to an internal factor. He himself is to blame because he is careless.

W: So if I said it was because of heavy traffic or something, I'd be attributing his behavior. to an external factor, something beyond his control.

M: Good. Now how do we usually explain our own negative behavior？

W: We blame external factors.

M: That's right.
