来源：学生作业帮 编辑：作业帮 分类：英语作业 时间：2024/05/15 20:02:41
老师,我英语的从句还有些不太懂,例如:定语从句,等等.还有一些关系代词也不太明白,怎么分析此类句子?
解题思路： 这类知识需要牢记
解题过程：
一 名词性从句:
1. 主要包括主语从句,宾语从句,表语从句和同位语从句. 一般由that 引起,也可由who, what, when, why, which, whom, whether, how 引起.
What you need is more practice.
The question is whether it is worth doing.
We must find out who did all this..
2. 主语从句很多情况下都可以放到句子后面,而用代词it作形式上的主语. 例如:
It isn’t likely that I should accept such an offer as that.
It is still a question when we shall have our sports meet.
3. 形式宾语
I think it best that you should stay here.
She took it for granted that he would receive it with shame.
4. 由名词性关系代词whatever, whoever, whichever 等引起的宾语从句
He will do whatever the teacher asks him to do.
I’ll take whoever wants to go with me to the theatre.
Take whichever you like best.
5. whether and if 都能引导从句, 但用法有所不同. 当主语从句直接位于句首时,应用whether,而不用if. Whether 后能直接or not, 但if 不能.
Whether he will come or not is not known.
6. 在名词reason后的表语从句必须用that引导, 不可误用 because.
The reason why he is often late for class is that he has the bad habit of getting up late in the morning.
二: 定语从句
1. 引导定语从句的关系词有who, whom, whose, that, when, where, why and which. 在非限制定语从句中, 只可用which, who, whose, where , when., 如果指代前面整个句子, 多用which.

This is the reason why he refused to help us.

2. 当引导定语从句的先行词前有all, any, no, little, much, very first 等词, 或先行词前为形容词最高级所修饰时,或先行词为all, anything, nothing, something, everything 时,从句的引导词只能用that.
The only thing that matters to the children is how soon they can have their holiday.
3. as 可做引导词引导定语从句, 多和such, the same 连用. As 引导的定语从句也可修饰整个句子, 既可放在先行词后,也可放在句子开头.
Such people as you describe are rare nowadays.
The boy was run over by a motor-car, as often happened in pre-liberation Shanghai.
4. 介词+which/whom/whose从句
