在名词性从句中what充当什么成分(what名词性从句用法)

导语:名词性从句中what可以指代什么?

大家都知道名词性从句中我们可以用what指代物品或事情,那么它还可以指代别的东西吗?它可以指代时间、地点、原因吗?

我们先来看看下面的例子:

1. As his best friend, I can make accurate guesses about_________ he will do or think.

A. what B. which C. whom D. that

2. She is no longer __________ she used to be.

A. who B. whom C. what D.where

3. Qatar is a tiny country hosting__________ is called the most impressive Asian Games ever.

A. that B. what C. which D. when

4. Many young people in the West are expected to leave____________ could be life’s most important decision-marriage-almost entirely up to luck.

A. as B. that C. which D. what

5. A modern city has been set up in __________ used to be a waste land 10 years ago.

A. what B. which C. that D. where

6. When asked___________ they needed most, the kids said they wanted to feel important and love.

A. what B. why C. whom D. which

7. We can meet at __________ you think is a suitable time.

A. / B. when C.while D. what

我们先要确定做题顺序。首先要确定这是一个名词性从句。如果这个从句在句子中作为主语、宾语、表语或同位语,那我们就可以确定这是一个名词性从句。然后我们要严格按照定语从句规则来分析句子,不要把名词性从句的规则和其它从句的规格混淆。

如果从句缺乏主语、宾语或表语,而且其主语、宾语或表语是事或物,那就需要用what引导从句。如果其主语、宾语或表语是人,就用who或whom。

解析:

1、答案选A。作为他最好的朋友,我可以准确猜测到他会做什么和想什么。从句是_________ he will do or think。这是about的介词宾语,自然是名词性从句。从句内部缺少do or think的宾语,所以选择what。

2、答案选C。她再也不是曾经的她了。从句__________ she used to be是is的表语,而表语从句中缺少表语,其表语是物,所以用what。注意,这里很多人会认为表语是指的人,其实不是,这个问题我会另文详述。

3、答案选B。从句__________ is called the most impressive Asian Games ever是hosting的宾语,从句内部缺乏主语。

4、答案选D。从句____________ could be life’s most important decision-marriage是leave的宾语,是名词性从句,从句内部缺主语。

5、 答案选A。从句__________ used to be a waste land 10 years ago是in的介词宾语。从句内部缺乏主语。

6、答案选A。从句___________ they needed most是asked的宾语,从句内部缺宾语。

7、答案选D。从句__________ you think is a suitable time是at的介词宾语,从句内部缺主语。

可以看出what的应用范围非常的大,可以指代事情、物品、想法、时间、地点、原因等等。其判断方法要兼顾语法规则和句意。
