3．考查as/which引导的非限制性定语从句。尤其要重视which，as引导的非限制性定语从句和it，what引导的主语从句的区分。
4．考查定语从句中的主谓一致现象。如：
I, who am your close friend, will try my best to help you whenever you are in trouble.
5．考查“介词＋关系代词”引导的定语从句。“介词＋关系代词”引导的定语从句，关系代词指人时用whom，指物时用which，不能用that。关系代词作定语时也可用whose。如：
The teacher in front of whose house stands a tall tree is very patient with his students.
同时还要重视“复杂介词或代词”出现时与并列句的区别。如：
He loved his parents deeply, both of whom are very kind to him.(定语从句)
He loved his parents deeply and both of them are very kind to him.(并列句)
此外，“介词＋which ＋名词”结构，也是一个较为特殊的结构。如：
