两者都可指物,常可互换。其区别主要在于。如:
1. 引导非限制性定语从句时,通常要用which。如:
She received an invitation from her boss, which came as a surprise. 她收到了老板的邀请,这是她意想不到的。
2. 直接放在介词后作宾语时,通常要用which。如:
The tool with which he is working is called a hammer. 他干活用的那个工具叫做锤子。
3. 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。如:
There was little that the enemy could do but surrender. 敌人无法,只有投降了。
All [Everything] that can be done must be done. 凡能做的事都必须做。
4. 当先行词有the very, the only, the same 等修饰时,通常用that。如:
This is the only example that I know. 我知道的例子只有这一个。
Those are the very words that he used. 那是他的原话。
5. 当先行词有形容词级或序数词(包括last, next等)等修饰时,通常用that。如:
This is the best dictionary that I’ve ever used. 这是我用过的的词典。
The first thing that you should do is to work out a plan. 你应该做的第一件事是订个计划。
6. 当关系代词在定语从句中用作表语时,通常用that。如:
China is not the country (that) it was. 中国已不是过去的中国了。
7. 当先行词是一个既指人又指物的并列词组时,通常用that。如:
They talked about the persons and things that most impressed them. 他们谈论了使他们印象最深的人和事。
8. 当要避免重复时。如:
Which is the course that we are to take? 我们选哪门课程
