【答案解析】[听力原文]
M: Let me see. I have printed my family name, first name, date of birth, and address. Anything else?

A
【答案解析】[听力原文]
M: I hate memorizing vocabulary.
W: Well, it's part of learning a second language. If you want to master the language, it is a must.
“memorizing vocabulary”是“记单词”的意思，第一个讲话人抱怨不喜欢记单词，而第二个人说“If you want to master the language，it is a must．”理解这句话是解题的关键，它的意思是“如果你想掌握一门语言，词汇是必需的。”其实相当于“Vocabulary is necessary”。

What does the man imply?
【正确答案】
D
【答案解析】[听力原文]
W: That's a great sweater. I've never seen anything like it before.
M: You think so? My grandmother made it for me years ago. But this is the first time I dare to wear it in public.
解题的关键是理解讲话者在说“But this is the first time I dare to wear it in public”的意思，“dare to do”的意思是“敢做……”。既然很早就有这件衣服了，但这刚刚是第一次穿出来，说明说话的人对这件衣服没有信心。所以答案选择D。
