引导的定语从句可置于句首，而不可。
做行为动词的主语，从句中的关系代词只能用。as 在从句中做主语时，从句中的谓语必须是系动词，而不能为行为动词。
译为“正如，好像”时，只能用。
考点五：the way 做先行词的用法：

5. The reason _____________ he was late isknown to us.先行词在句中做________语
(2)直接放在介词后作宾语which。
(3)which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句中，which可以做主语，也可以作宾语或表语， 不用that。
考点三：whose的用法：
例1. The student______father works in the factory is sitting there.
Smoking is harmful to one’s health, as we all know.
Jim passed the driving test, _____ surprised everybody in the office.
总结： 在非限制性定语从句中，as引导的非限制性定语从句既可以放在主句，也可以放在或 ____；指代主句的；which引导的非限制性定语从句只能位于主句，可以指代前面的某个或。
I am looking for my glasses,withoutwhich I can’t watch TV clearly.
表示部分的词语＋of＋关系代词
在这种结构引导的定语从句中要注意以下几点：此时指人的关系代词只能用whom．指物的只能用which；表示部分的词语常见有：不定代词all，both，none，either，some，any；数词(包括基数词、常数词、分数和百分数)；数词+名词；the+最高级／比较级， 以及表示数目或数量的词语many，most，few，several，enough，half a，a quarter等。
