教我分析英语从句中,哪个是主句哪个是从句的问题?
例如,all of us know that we must study hard 中.all of us know 是主句还是we must study hard 是主句呢?

从句的作用就是充当主句的成分.通常情况下从句前面有引导词.(that what who where之类的).最简单的办法就是找引导词.引导词后面的就一定是从句.但是如果想彻底搞清这个问题,你要先学会分析简单句的句子成分.然后再进一步分析复杂句中,主句少什么成分,从句就是充当什么成分.
下成这几个例子是不同的从句.已经把从句用刮号标出了.
表语从句:This is (what I want to know).
宾语从句:He was afraid (that his baby would touch that cat).
定语从句:I want to have the book (that you have bought yesterday).
状语从句:She turned on TV set and sit down (when a thief came into her room).
同位语从句:We have learned the news (that our friend won the game).
