22、引导的定语从句可以放在句首,而which则不能。As is known to us all,China is developing rapidly.众所周知,中国发展迅速。,(2)as表示“正如,正像”,而which无此意。此时,as从句中常有know,expect,happen,point out,plan,suggest等单词或短语。He came back home late,as we expected.正如我们所料,他回家晚了。注意:as引导的定语从句常见句式有：as is known to all(众所周知),as is often the case(经常是这个情形),as is

25、名词。如：The classroom whose door/the door of which/of which the door is broken is on the second floor.,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
26、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
27、 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：He was very ill,in which case(and in this case)we sent him to hospital first.,6.考查一些特殊的先行词。如:当situation,point,case,activity,scene及period,festival,occasion等出现时,要注意具体情况具体分析;作主语、宾语和表语时,用关系代词that/which;作状语时,用关系副词where/when或“介词which”,表示在某种特定的情形下。,7.考查定语从句、强调句、
28、时间状语从句等的区别。如：The news that he had passed the exam pleased him and his family.(同位语从句)The news(that)he told me this morning is not interesting.(定语从句)It was 1914 when the war broke out.(时间状语从句)It was in 1914 that the war broke out.(强调句),真题再现,1._ is often the case with children,Amy was better by the tim
