以下便是辛达雅思代报小编为咱们整理的雅思长难句主干剖析之从句。希望对各位考生的备考有所帮助：

Howdoes he finish that?（语句）

Howhe finishes that（名词性从句）

留意：who, what, which（哪一个）为疑问代词，若在问句中作主语，变为名词性从句时，结构不变。

Whocame here? （语句）

Whocame here（名词性从句）

Whathappened last night? （语句）

Whathappened last night（名词性从句）

Whichwas bought? （语句）

Whichwas bought（名词性从句）

名词性从句有时候也能够省掉成名词性短语，也相当于名词的效果。

Wherewe should meet him is not decided yet.

Whereto meet him is not decided yet.

How we can handle the problem depends on your decision.

How to handle the problem depends on your decision.

名词性从句一般能够作主语、宾语、表语和同位语。

Whether he can do it is a problem.（作主语）

I did not believe what he said. （作宾语）

I am worried about whether she can do it. （作介词的宾语）
