3)关系代词只使用that，不使用which的情况。
(1) 关系代词前有形容词的最高级修饰时。
This is the funniest drama that I have seen.这是我看过的最滑稽的剧。
(2)先行词为不定代词。如：all，everything，nothing，anything，both．either，much，little，none。
例：①Everything that was taught in class seemed easy for him. 对他来说课堂上教的一切似乎很容易。
(3)先行词为only，very等词修饰肘。
例：①It was the only textbook that could be found．这是能够找到的仅有的一本课本。
②This is the very dictionary that I want to get．这正是我想得到的词典。
(4)定语从句中固定短语动词和短语中的介词不能前置。
例：It was the maths book that the boy was in search of．这是这个男孩正在寻找的数学书。
5)whose与of which/whom
(1)都可表所有关系。
(2)of which/whom还可表示"其中的……"(整体的部分)
例：He told us many stories about Long March，of which this is a good example.他给我们讲了许多关于长征的故事，这是其中一个很好的例子。
as和which引导的非限制性定语从句比较:
下面是近年高考题中关于定语从句的试题
1.The result of the experiment was very good, ____ we hadn't expected． (NMET2000，10)
2.Dorothy was always speaking highly of her role in the play，____,of course，made the others unhappy.
(NMET2000，17)
A.when B.which C.this D.what
3．Carol said the work would be done by October,____ personally I doubt very much．(NMET99，19)
A.it B.that C.then D.which
4.The weather turned out to be very good,____ was more than we could expect. (NMET94,39)
A.what B.which C.that D.it
它们的答案分别是C、B、D和B，都是用which引导一个非限制性定语从句，which代替逗号前整个主句的内容。
但有时关系代词as也可引导非限制性定语从句，as也是代替整个主句的意思。如:
As we all know，he never smokes. The foolish boy made the mistake again，as could be expected. ____ is mentioned above，the number of students in senior high school is increasing．('99上海，4)
A.Which B.As C.That D.It
关系代词as和which引导的非限制性定语从句区别究竟在哪里呢?
1．非限制性定语从句位于句末，而且as或which在从句中作主语、宾语或表语时可互换。如:
He is a farmer as/which is clear from his manners．(在从句中作主语)
This elephant is like a snake，as／which anybody can see．(在从句中作宾语)
2. which引导的非限制性定语从句一般放在句末，而as引导的非限制性定语从句可放在句末，也可放在句中、句首。置于句首时，不能用which替换。如：
Crusoe lost his dog, which made him very sad.
Taiwan is part of China, as/which is known to all.
As we have seen, oceans cover more than 70 percent of the earth.
3.as引导非限制性定语从句时，意为"这一点"、"这件事"，常与see，hope，expect，know，guess等动词搭配；而which引导非限制性定语从句时，与主句有一种因果关系，可译为"所以……"。如：
Cyprus, as you all know, is in the Mediterranean．大家都知道，塞浦路斯在地中海。
Bamboo is hollow，which makes it very light。竹子是空的，所以很轻。
4.as引导非限制性定语从句，并在从句中作主语时，其后面的谓语动词必须是连系动词。如果从句谓语动词是行为动词，则必须用which。如：
He married her，as was natural.
She refused to take the medicine，which made her mother angry．
It rained hard yesterday，which prevented her from going to Shenyang.
但若从句谓语是usually, happen，be often the case等时，仍用关系代词as，不用which。如：
He is absent，as is often the case.
