that在定语从句中只能作什么成分
that在宾语从句中可以作宾语么？
that在宾语从句中可以作宾语么？
that在名词性从句里都是不充当成分的，没有实际意义，包括宾语从句，主语从句，同位语从句，表语从句，并且在宾语从句里经常省略，所以，不能用that做主语。另外，that在定语从句中是做成分的，可以做主语。不一定要用it，根据句子需要例如：He admitted that he would be our new manager. he是主语，that不做成分，无意义 He admitted that it was difficult to work with Tom. it 做形式主语
that在定语从句里，可以代指复数主语吗？
当然可以啊，定语从句的引导词与先行词是复数还是单数无关的，最重要是先行词在从句中所作成分，还有就是先行词如果在从句做主语时，从句的谓语动词的数需要与先行词一致。例如：I like the books that were bought yesterday.I like the food that is cooked by my mother.
that在非限定性从句中指代什么？
THAT在定语从句绝对可以做主语，这个跟LZ的问题一点关系也没有。比如： I can`t accept any result that is not fair.这个定从中that很明显是做主语。 非限制性定语从句中的先行词与限制性定语从句一样，可以做主语、宾语、状语，区别只在于非限制性定语从句中先行词指代的成分选择的范围比限制性定从大，它可以指代前一句的某个成分，也可以指代前一句的全部内容。 至于为什么非限制性定从一定要用which开头而不是that，这个也许完全是英语使用的习惯原因，没什么可深究的技术性原因，知道就行。
that在定语从句中作什么成分？
你好，
that指代人或物.在定语从句中作主语、宾语或表语.如
The students that like English often learn from each other. ( that作主语,相当于who )
I saw the girl that you like. ( that作宾语,相当于who或whom )
The car that is over there is mine. ( that作主语,相当于which )
The trees that they planted grow very well. ( that作宾语,相当于which )
He is not that man that he was. (that作表语)
