英语句式问题。

My idea is that we (should ) think it over before accepting it.
my idea 是主语
is 是谓语
that we (should ) think it over before accepting it.宾语部分。
在这个宾语中 we 是主语，think over是动词短语作谓语，it是宾语，before accepting it是时间状语。
My suggestion that we (should) have a meeting has been accepted by others.
My suggestion 是主语 that we (should) have a meeting 是同位语，因为它就是指的suggestion
has been accepted by others整个是谓语部分。
这句是典型的同位语从句。

1. my idea 主语，is 系动词，that we should think it over before accepting it 表语从句。
before accepting it 是一个介词短语，before 是介词，在介词后面的动词要用 -ing 形式。原句意思是：我的观点是在接受它之前应当仔细考虑一下。
2. my suggestion 后面的 that 从句是一个同位语从句，has been accepted by others 是主句的谓语，用了现在完成时的被动语态，原句意思是：我所提的我们应该开个会的建议已经被其他人接受了。
