注意：先行词是表示地点或时间时，有时用where或when，有时用that(which)引导定语从句，这时要根据从句的谓语动词是及物的还是不及物的。如果是及物的就用that(which)，否则用where或when。例如： This is the house where he lived last year.
This is the house that(which)he visited last year. I thought of the happy days when I stayed in Beijing.
I have never forgotten the day which we spent together.
5.限定性定语从句和非限定性定语从句：
①限定性定语从句是句中不可缺少的组成部分，主句和从句之间不用逗号分开，引导非限定性定语从句的关系代词有who,whom,whose,which,of which等，这些关系代词都不能省略；
②非限定性定语从句是对主句先行词的补充说明，没有这种从句不影响主句意思的完整，一般用逗号把主句和从句分开。关系代词用which，不用that；指人时可用who，例如：
I have two sisters,who are both students.
Crusoe's dog,which was now very old,became ill and died.
6.as引导的定语从句：
①as用作关系代词和关系副词引导限定性定语从句，并在从句中作主语、表语或状语，构成the same…as,such…as等结构。例如：

I shall do it in the same way as you did.（as作状语）
I want to have such a dictionary as he has.(as作宾语）；
②as引导非限定性定语从句。as在定语从句中作主语、表语或宾语，这个定语从句说明整个句子，可以放在主句之前。例如：
As we all know,he studies very hard.（as代表整个句子，作宾语）
As is known to all,he is the best student in our class.（as代表整个句子，作主语） 常用的这种类似插入语的句式有as is said above,as is already mentioned above,as is known to all,as it is,as is often the case,as is reported in the newspaper等。
注意：①关系代词在从句中作主语时，从句的谓语动词的人称和数必须和先行词保持一致；②关系代词whom,which,that在限定性定语从句作动词宾语或介词宾语，而该介词又位于从句末尾时，经常省略，但as一般不省略；③关系代词which和as在定语从句中的区别是：which不能放在句首，而as则可以；在句中时，as有\正如\就像\之意，而which则没有此意。
