听力原文:M: We continue with the World of Investigation. Laura, an identical twin, has agr
W: Of course we are.
M: Interesting! You said "of course". Don't you think there are quite a few sisters who aren't close?
W: Sarah and I aren't just sisters. We're identical twins.
M: I take your point. How identical are you, in fact?
W: Both blonde, with brown eyes. Same height, same weight, same size. Even shoes.
M: As you're the same size, have you always dressed alike?
W: Oh yes. I'm told it started when we were babies. Mum made a feature of her twins. And then we got into the habit of buying two of everything.
M: And you've never minded having a double identity? I mean...an other person exactly like you?
W: Sarah isn't exactly like me. We may look identical, but I remember our boyfriends couldn't tell us apart.
M: Didn't that cause problems?
W: For them, perhaps. Not for us. We couldn't stop laughing.
M: I think you said you and Sarah weren't exactly alike? Just what did you mean by that?
W: Sarah has a well-fed happy husband and four healthy children. When she was washing up, I was learning to type. When she was knitting, I was writing articles for the school newspaper. When she was having her second child, I was in Panama, doing my first job for United Information Services. See what I mean?
M: And haven't you got a healthy husband and happy children?
M: And haven't you got a healthy husband and happy children?
W: You must be joking. There's never been the time ... or the inclination.
M: Laura, you've made some very interesting points. I gather that you don't feel that behaviour is purely genetic ... that there might be some element of environment or choice or even perhaps ...
W: Shall I conclude? Sarah and I are identical twins ... in appearance, that is ... but it's a fact that life has presented us with different opportunities, se we've led very different lives.
