IwillneverforgetthedaywhenImetyou注意：先行词为时间、地点、原因时，引导词不一定都要用when或where或why引导，要判断它在定语从句中的句子成分。如果引导词在定语从句中作主语或宾语，就要用which

介词+关系代词分析下列例句:Themanto

whomheistalkingismyfather.Thisisthepenwith

whichIwrotetheletter.注意：“介词+关系代词”引导的定语从句时，介词的宾语只能用which（指物）和whom（指人）。即：介词+which/whom/whose1.介词的选择依据：①取决于从句中v/adj短语搭配

Thisisthebook_____whichIaminterestedThisisthebook_____whichIpaidtenyuan

②取决于先行词（air,tree,building

）

Everyoneneedsair,_____whichwecouldn’tlive③取决于句意表达

Thisistheboy,_____whomIwenttoschool.inforwithoutwith注意：有一些含介词的动词短语不可拆开，如lookafter,lookfor等不能把介词移至whih或whom之前。2.复合介词①ontopof/infrontof/atthebackof…which/whom+v+s

(完全倒装）

Thisisthemountain,ontopofwhich

standsatree.②名词/分数/百分数/不定代词/the+adj比较级/the+adj最高级+one+of
