题目

that引导的宾语从句有没有可能that在从句中担当主语,
that引导的从句太多了,有点乱,
定语从句中that既是关系词又可以作主语是吧,比如说
it is the most beautiful thing that was ever given to me
如果我说
it is the most beautiful thing that that was ever given to me
两个that,第一个当关系词,第二个当主语,这样是不是就不对了?
宾语从句中that可不可能也既当连词又当从句的主语,比如说
i think that that is my book
这就有两个that,但确是对的,如果我说
i think that is my book
that 既是连词同时又是从句的主语,
还有个问题就是that的省略,that在宾语从句中都可以省略?还是that在宾语从句中作宾语可以省略?在定语从句中作宾语能省略吗?

答案

it is the most beautiful thing that that was ever given to me
两个that,第一个当关系词,第二个当主语,这样是不是就不对了?
这个肯定是不对的,因为在这句话是定语从句,定语从句的作用是修饰,在定语从句中,that指的是物,如果要用that,那么它必须在从句中做主语或宾语.
i think that that is my book
这就有两个that,但确是对的,
这句话是对的,因为这个句子是宾语从句,在宾语从句中that是不做任何成分,如果指物用what,指人用who,宾语从句中that可以省略.但一般不会这样子写,前一个that要省略.
i think that is my book
that 既是连词同时又是从句的主语,对不对?
这样的理解是错的,它是省略了连词.
