英语从句的问题

主句和从句哪些情况加that，哪些情况不加that

Answer 1

(A) that & which:
在定语从句中，which 和that 在指代事物时，一般可以互换使用，但并非在任何情况下都是这样，这里介绍宜用that, 而不宜用which 的情况.
(1) 先行词为不定代词，如all, much, something, everything, anything, nothing, none, the one等。如：
1.We should do all that is useful to the people .
2.There's nothing that can be said about it .
3.Do you mean the one that was bought yesterday?
(2) 先行词被only, any, few, little, no, just, very, one of等词修饰时。如：
1.The only thing that we could do was to wait.
2.That's the very word that is wrongly used.
3.The last place (that) we visited was the chemical works.
4. You can take any (=whichever) seat that is free.
5. I hope the little that I can will be of some help to them.
6.比较 *This is one of the best novels that were published last year.
*This is the only one of the best novels that was published last year.
(3) 先行词是序数词时或被序数词修饰时。如：
1.When we talk about Wuxi, the first that comes into mind is Tai Lake.
2.This is the third film that has been shown in our school this term.
(4) 先行词是最高级或被最高级修饰时。如：
1.This is the best that can be done now.
2.The most important thing that should be done right now is how to stop him from going on.
(5) 先行词既有人又有物，用which和who都不适合，这时宜用that. 如：
1.The writer and his novel that you have just talked about is really well known .
2.The rider and his bike that had run over an old woman were held up by the police.
(6) 被修饰词为数词时. 如：
1.Yesterday I caught two fish and put them in a basin of water .Now you can see the two that are still alive .
(7) 如果有两个从句，其中一个关系代词已用which ,另一个关系代词宜用that，以避免语言的单调或重复。如：
1.Edison built up a factory which produced things that had never been seen before.
(8) 疑问词是who或which，关系代词宜用that，以避免重复。如：
1. Which is the book that you like best?
2. Who is the man that is standing at the gate?
(9) 主句是There be 结构，修饰其主句的定语从句宜用that 作关系代词. 如：
1. There is still a seat in the corner that is still free.
(10) 被修饰成分为表语时，或者关系代词本身是定语从句的表语时，该关系代词宜用that . 如：
1. That's a good book that will help you a lot.
2. My home village is no longer the place ( that ) it used to be .

定语从句中宜用which而不宜用that 的情况:
(1) 当关系代词的前面有介词时. 如：
1.A zoo is a park in which many kinds of animals are kept for exhibition.
2.Is this the room in which Mr. White lives?
(2) 在非限制性定语从句中. 如：
1.Crusoe's dog, which was are now very old, became ill and died .
2.More and more people are beginning to learn English, which is becoming very popular in our country. (which指代主句)
(3) 在一个句子中有两个定语从句，其中一个定语从句的关系代词用了that, 另一个宜用which . 如：
1. Let me show you the novel，that I borrowed from the library which was newly open to us.
2. At the station I bought some magazines that might help me to pass the time on the train and which I could pass on to others when I finished them.
(4) 当关系代词后面带有插入语时. 如：
1. Here's the English grammar which, as I have told you, will help improve your English.
(5) 先行词本身是that, 宜用which . 如：
What's that which she is looking at?
(6) 先行词是those+复数名词. 如：
A shop should keep a stock of those goods which sell best.

Answer 2

如果说
The
truth
that
you
leave是同位语从句
那
the
day
you
went
away
是什么？
我先帮你解释这个吧
The
truth
that
you
leave这句话的确是同位语从句，因为that后面的是一句句子。其实这个要理解很简单的：The
truth
that
you
leave这个事实，什么事实呢？就是我离开的事实。that后面的是补充说明的作用
而the
day
you
went
away
中省略了that，这句话是定语从句，你知道为什么吗？因为这句话可以说成是you
went
away
the
day。the
day
在这句话中是有成分的。而上一句不可能翻译成
you
leave
the truth
吧
其实在我看来，定语从句和同位语从句的区别是：
1）that后面是不是一句句子，是句子的话，就是同位语
2）把that前面的词带到that后面，看看翻译的通不通。
以上是我个人的片面之词，全是我凭自己的理解。如有什么不妥之处，还请包涵。(*^__^*)

the
day
you
went
away

i

never
forget
the

we

the
days
和we
之间省略了that

Answer 4

the

you
went
away

the
days
和we

定语从句
后面是个完整句子
修饰the
days

Answer 5

that 是引导宾语从句时可以省略，做定语时和引导主语从句时不可以省略。
