老师您好,是这样的, 在what引导的名词性从句当中, 查阅相关资料都说的是what可以在从句中充当主语, 定语 ,宾语 ,表语,等等, 但是没有资料说可以充当谓语, 我以前也是这么认为的,但是最近突然被困在了这个点里面,我发现what是可以充当谓语的,以what引导的主语从句为例子
1.What makes me happy is your smile
在这个句子中,what充当主语从句的主语,而is后面的内容正是what所代表的内容。
2.What I have is a house
在这个句子中,what充当主语从句的宾语,而is后面的内容也正是what所代表的内容
然而 在这个句子中
3.What I want to do is to go swiming
这个句子,按照各大语法书上面来分析的话,what都充当的是do的宾语,可是按照这么理解的话,is后面也应该是what的内容,即动词do的宾语才说的通呀,为什么系动词后却是动词不定式?
按照语法书上面的逻辑,我造了一个句,What I want to do is homework , homework 是what的内容 ,做do的宾语, 这样我觉得才说得通,然后在学习中我发现What I want to do is to go swiming这种句型反而更常见,因此想请问一下,what到底充当的什么成分,是宾语还是谓语?
网友把很简单的问题考虑复杂了。其实,不定式to do sth. 本身就具有“名词意义”,相当于一个名词。例如:
My dream is to go to college.
Her job is to look after children.
以上两句中,句子主语是名词。
由于名词性从句在本质上具备名词的作用。所以,我们把主语转换为名词性从句:
What I dream of is to go to college.
What she does is to look after children.
此外,网友认为,what 引导名词性从句时,其表语应该是sth. 如:
What I want to do is homework. 当然这也没错。
其实,sth. 跟不定式,可以划等号。例如:
My dream is to go to college.
Her job is to look after children.
正着说、倒着说,都一样:
To go to college is my dream.
To look after children is her work.
把表语换成名词性从句:
To go to college is what I dream of.
To look after children is what she does.
至于what 从句在主句中作的成分,以及what 在从句中所作的成分,应该很好判断。举例如下:
从语法作用看,what引导的这个句子叫做名词性从句,因为它起的作用就相当于一个名词。那么,what从句在主句中可以做什么成分呢?请看例句:
What we need is their help. (做主语)我们所需要的就是他们的帮助。
He has got what he wants. (做宾语)他得到了他想要的东西。
That is what I heard on the bus.(做表语)那就是我在公共车上听到的故事。
what 本身在它引导的从句中做什么成分呢?请看例句:
What appears difficult may be very easy. (做主语)看起来很难的事情也许很容易。
What we liked most was his jokes.(做宾语)我们最喜欢的(东西)就是他讲的笑话。
China is not what she was more than 50 years ago.(做表语)中国已不是50多年前的中国了。

what为融合性关系代词/复合型连接连接代词引导主语从句。what=the thing that,what在主语从句也作主语成分
2.What I have(主语)// is(系动词) a house(表语)(主语从句)
=The thing that I have is a house(定语从句)

解答:

3.What I want to do(主语)// is(系动词)// to go swimming(表语)
=To go swimming is what I want to do

备注:前面出现TO DO,后面不定式TO可以省略。
这个句子,按照各大语法书上面来分析的话,what都充当的是do的宾语,可是按照这么理解的话,is后面也应该是what的内容,即动词do的宾语才说的通呀,为什么系动词后却是动词不定式?

what引导主语从句,并在主语从句作非谓语动词,不定式to do宾语成分。
以上3个句子都是主系表结构,第1和2都是名词作表语,第3个为不定式作表语,主语从句都是WHAT引导关系分词作主语从句
