3个回答

一、用作疑问代词,用来构成特殊疑问句:

1.与表示人的名词或人称代词连用,用来提问对方或第三者的职业或身份.例如:

What is Comrade Liu?刘同志是做什么的?

“What are you?” “I'm a worker.” “你是做什么的?”“我是工人.”

2.与介词like连用,表示“怎么样”和“象什么”的意思.例如:

What is the weather like today?今天天气怎么样?

What is the elephant's leg like?大象的腿象什么?

What does your girlfriend look like?你女朋友长得什么样?

3.与about连用,用来表示征求意见或询问消息,表示“对于……怎么样”的意思.例如:

What (is your opinion) about going out for a walk?我们出去散散步怎么样?

You didn't recognize your uncle at the station at once?What about your elder sister?你在车站没有立即认出你叔叔?那你姐姐呢?

4.与介词for连用,表示“为了什么目的”的意思.例如:

What will your father go to Beijing for?你父亲去北京干什么?

二、用作疑问形容词:

1.用来表示“多少”的意思.例如:

What does a Chinese-English dictionary cost?买一本汉英辞典要多少钱?

What's the date today?今天几号?

2.用来构成感叹句,表示“多么”的意思.例如:

What a happy life we are living!(= What a happy life we are having!=What a happy life we are leading!=What a happy life we are enjoying!) 我们过着多么幸福的生活啊!

3.用来说明名词,作前置定语,表示“什么”和“怎样的”的意思.例如:

What time is it by your watch?你的表几点了?

What time do you get up every day?你每天什么时间起床?

What size do you want?你要多大尺寸的?

三、用作连接代词,用来引导主语从句,宾语从句和表语从句.例如:

What you said just now is very important.你刚才说的很重要.(引导主语从句)

注:

1.“What ...is ...”是个强调句型,常译为“……的是……”,what通常作主语从句的宾语,有时也可作主语从句的主语.例如:

What troubles me most is that I don't know how to tell her the bad news.最使我苦恼的是我不知道该怎样告诉她这个坏消息才好.

2.“is”后可接一般的表语,也可接表语从句.(如上面的两个例句)

I didn't understand what you had said.我不理解你说的话.(引导宾语从句)

The question is what we can tell him.问题是我们能告诉他什么.(引导表语从句)

此外,what可用在不定式前,和不定式一起在句中作宾语、主语或表语.例如:

I don't know what to do.我不知道该做什么好.

What to do has not been decided yet.做什么还未决定.

The question is what to do.问题是做什么?
