Question 15 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.

15. What did the grandmother of the man’s wife say?

解析：B。本题目细节题。问题为：男士妻子的祖母说了什么？根据原文“M: She said her grandmother reckoned you had to shave your head to get it out. My wife was really terrified.”，男士妻子说她祖母认为必须将头发剃掉才能把蝙蝠从头发上赶出去，他的妻子至今都很害怕。正确选项B）One would have to shave their head to remove a bat in their hair ，与原文信息相一致。本题目干扰选项较多，因为重现原文的还有A、C、D，但是干扰选项的主体不是此题目问题的主体。此题目问的是男士妻子的祖母，而不是对话中女士以及男士本人所听到的恐怖的说法。
