1、非限制性定语从句

水流湍急，使这条河很危险。

他们找寻的文件已找到了。
This morning some port wine came, for which I have to thank you.

注：有时“介词+which”引导的定语从句可以转换成“介词+which+不定式”结构：
He had only the long nights in which he could study. =He had only the long nights in which to study.
他只有漫漫长夜可用来学习。
He had a couple of revolvers with which he could defend himself.= He had a couple of revolvers with which to defend himself.
他只有一两把手枪用来自卫。
3、先行词
当先行词是下列不定代词或被它们修饰时much, little, none, all, few, every(thing), any(thing), no(thing) 等时，通常用that：
All that she lacked was training.
她缺的只是训练。
Have you everything that you need?
你需要的东西都有了吗?

which和that的区别：
1只用which,不用that的情况。
1)which可用在非限制性定语从句中。例如：
The project,which lasted four years,cost one billion dollars.这项工程历时四年，耗资十亿美元。
2)which可用前置介词宾语。例如：
This is the house in which we lived three years ago.这是我们三年前住过的那所房子。
2只用that，不用which的情况。
1)that相当于关系副词when,where,why,in the way＝in which。例如：
I'll never forget the Monday that /when you first arrived.我将永远不会忘记你初到的那个星期一！
Do you know anywhere that I can get fruit?
你知道我能在哪里买到水果吗？
2)that既可指物，也可指人。例如：
The people that worked on the project made a good effort.从事那项工程的人们做了很大努力。
3)当主句以here,there开头时，常用that。例如：
Here is the place that you've been looking for.这就是你一直找的地方。
4)当先行词是序数词、形容词最高级或先行词被序数词或形容词最高级修饰时，常用that。例如：
The first(thing)that should bed one is to get the book.应该做的第一件事是弄到那本书。
5)英语的学习不是一朝一夕的，是需要长时间的积累过程，单词，语法，听力，这些是最基本的，不过最主要的是口语的练习，多听多练是最有效的，最好是可以经常和外国人交流，进行语言的交换，文化的交流也是可以提升外语的。
