Question 13 is based on the conversation you have just heard.

听力原文：

M:（12）You know, Ben’s given up making those terrible faces he used to make. The other day, he came home from school almost in tears. His teacher said if he went on like that, his face would get stuck when the winds changed.

W: And he believed her?

M: Yeah, he’s only a little boy. Don’t you remember all those things we used to believe when we were little?（13）I remember my aunt Mary used to say if you swallow a cherrystone; a tree would grow out of your mouth. And I’m still terrified today, sort of subconsciously. You know, if I swallow one by mistake…

W: Yeah, I suppose you’re right.（14）The one that used to get me was that swans could break your leg when they blow of the wing.

M: They can, can’t they? I always thought they could.

W: No, they are not that strong. But there’s another one even more terrifying. That is, if you put a post stamp on upside down, you will go to prison.

M: No, never heard of that. But my grandmother was a terror for that kind of thing. For example, she would say, you will get a spot on your tongue if you tell a lie. If you eat stale bread, your hair will curl. And here’s one more. We went on a campaign trip once in Italy, and my wife spent the whole time worrying about bats getting into her hair.（15）She said her grandmother reckoned you had to shave your head to get it out. My wife was really terrified.

W: Silly, isn’t it? But that’s how some parents try to keep their kids from doing the wrong thing or getting into trouble.

13. What did aunt Mary use to do when the man was a child?解析：D。本题目为推理题。问题为：男士小的时候，他的姨妈Mary曾经做过什么？根据原文“M: I remember my aunt Mary used to say if you swallow a cherrystone, a tree would grow out of your mouth. And I’m still terrified today, sort of subconsciously. ”男士说：“我记得我的姨妈Mary曾经对我说，如果我吞下去一颗樱桃核，一棵树将会从我的嘴里长出来。我至今很害怕，有点潜意识地害怕。”选项D）Warn him of danger by making up a story（讲恐怖的故事来警告他），与原文信息相一致。此题目需要在理解对话的基础上做出推理，难度较大。
