Question

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？

Answer 1

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).

Answer 2

从句可分为主语从句,宾语从句,表语从句,定语从句,同位语从句以及状语从句.
除了状语从句外,其它从句的分主从句的方式完全相同.即找出主从句的引导词,引导词之前就是主句,之后是从句.
状语从句有点区别.若句中没有逗号,那么判别方式和上面一样,如果句中有逗号,那么逗号前是从句,后是主句.
eg i was watching tv(主） when he arrived there（从）.
when he arrived there（从）,i was watching tv.（主）
we will go for a picnic if it doesn't rain tomorrow.
if it doesn't rain tomorrow,we will go for a picnic
有些定语从句可能也会和状语从句有相同的判别方式
as is known to us, taiwan is a part in china.

时间紧迫，要开会去了．如果你还有什么不懂的，尽管发信息问我，无任欢迎

Answer 3

all of us know 是主句
后面接的是that引导的宾语从句
其实不难啊 找出句子的 主语 谓语 和其他成分就好了啊
all of us 主语 know谓语动词 那that引导的从句自然就做宾语喽

从句都有引导词的`` 像 that which 等啊``
