What 引导的什么从句？

Question

What puzzles them is that it is a struggle for them to get used to senior English study.

Answer 1

一般what引导主语从句和宾语从句最多哦，当然还可以引导表语从句，定语从句（一般不考哦）等
你这句中what引导宾语从句，beyond是介词，介词后面加宾语，所以后面是宾语，而what在后面那句话中充当主语

Answer 2

what引导名词性从句，what=that it is...，整个句子是表语从句，因为表语是that引导的句子。主语从句是That it is a struggle for them to get used to senior English study puzzles them.

Answer 3

这个句子里面你问的这一个从句应该是做主语从句的。因为what引导的这一部分应该是后面后面的那一个动词的主语，使他们困惑的事情，整个作主语。

Answer 4

What puzzles them为名词性从句的主语从句，What puzzles them为主语，that it is a struggle for them to get used to senior English study为表语从句。
