介词引导的状语从句.pptx

定语从句，就是用来用来修饰名词或代词的句子，起到定语的作用，所以叫做定语从句。被修饰的词叫先行词。定语从句不同于单词做定语的情况，它需要放在被修饰的词（即先行词）之后。定语从句一般由关系代词来引导。关系代词必须放在定语从句之首。;关系代词：which/that（指物） who/whom/that（指人） 常用介词：in, to, of, about, from, on, for, against, among, as, around, at, before, below, behind, beside, besides, between, but, beyond, down;e.g.这就是从他那里我们学到很多东西的老师。 This is the teacher from whom we have learned a lot. e.g.我们所居住的城市发生了很大的变化。 Great changes have taken place in the city in which we live.; e.g.我们当时的处境很危险。 The situation(which/that) we had got into was very dangerous. e.g.你刚刚和他谈话的那个人是我的英语老师。 The man (whom/who/that) you were talking to is my English teacher. ;e.g.这是我正在找的那支钢笔。 This is the pen (which/that) I am looking for. e.g.她照顾的孩子有30个。 The number of the children(who/whom/that) she takes care of is 30.;e.g.我们班有四十个学生，他们大多数喜欢英语。 There are 40 students in our class ,most of them (=of whom most)like English. e.g.这些书是马克吐温写的，其中有一本我爸爸给我读过。 These are books written by Mark Twain ,one of which(=of which one) was read to me by my father.;e.g. I?live?in?a?room?whose?windows?are?all?broken.? =I?live?in?a?room?of?which?the?windows?are?all?broken.? =?I?live?in?a?room?the?windows?of?which?are?all?broken. e.g. This is my teacher whose handwriting is excellent. = This is my teacher the handwriting of whom is excellent. = This is my teacher of whom the handwriting is excellent. ;e.g. He has a good friend to whom he can turn for help. =He has a good friend to whom to turn for help. ;e.g. He used to live in London, from where he came from. e.g. He graduated from Beijing University in 1988, since when he has improved himself in all aspects.
