Unit 5 music (Grammar)“介词+ 关系代词”引导的定语从句●教学重点:非限制性定语从句●教学难点:介词的选取,关系代词的选取,关系代词的替换●教学内容:“介词+ 关系代词”引导的定语从句是定语从句中较复杂的一种,多用于正式文体中。

它们既可引导限制性定语从句,又可引导非限制性定语从句。
同学们在学习这种定语从句时要注意以下几种情况:一、注意介词的选取“介词” + “关系代词”引导的定语从句中,介词的选取应根据如下几点:1 .根据介词和定语从句中谓语动词的习惯搭配。
如:(1)Who is the man with whom you just shook hands?刚才和你握手的人是谁?(2)The two things about which Marx was not sure were the grammar and some of the idioms. 马克思不大有把握的两个方面是语法和某些习惯用语。
考例:In the dark street there wasn't a single person_____ she could turn for help.A. thatB. whoC.from whomD.to whom2 .根据定语从句意思的需要,此时不但要注意其前的搭配也要注意其后的搭配。
如:(1)He had a bad cold,because of which he didn't attend the meeting.他患了重感冒,因此未能参加会议。
考例 2 In the office I never seem to have time until after 5:30 p.m.,_______ many people have got home.A. whose timeB.thatC. on whichD. by which3. 根据意思也可用复杂介词,如by means of ,as a result of,in front of,in the back of ,all of ,most of 等,如:(1) There are forty students in the classroom,all of whom are working hard at a problem in mathematics. 教室里有四十个学生,他们都在努力计算一道数学难题。
必修二Unit 5 Music Grammar学习目标:1,掌握介词加关系代词的定语从句,灵活运用到考题中去。

3,激情投入,疯狂记忆,体验学习的快乐。
探究案第一部分:语法知识探究,“介词+ which / whom”引导的定语从句“介词+关系代词”引导的定语从句,是定语从句一种介词前置的定语从句句型,介词与关系代词之间存在一种介宾关系。
当关系代词在定语从句中作介词宾语时,把介词置于关系代词前,即演变出“介词+关系代词”句型。
例如:The man who/whom /that you spoke to is a teacher.=The man to whom you spoke is a teacher.一、基本构成1.“介词+关系代词”结构引导的定语从句中,关系代词只能用which(指物)或whom(指人) ,即:介词+which/whom。
(1)The man to whom you spoke is a teacher.(2)The city in which she lives is far away.(3)The little girl is reading a book,in which there are many cartoons.注意:当介词放在关系代词的前面时,用在介词后的关系代词不能省略。
2.在限制性定语从句中,当介词置于定语从句的谓语动词之后时,可用that/which(指物);that/who/whom(指人)作介词的宾语,且此处关系代词可以省略,特别是在口语中。
如:(1) The man (who/whom /that )you spoke to is a teacher.(2)The city(which/that)she lives in is far away.注:通常介词放在定语从句中动词后,也可以放在关系代词前面,但有些特殊动词短语搭配不能拆分,介词只能放在动词后,如:look for, look after, pay attention to ,take care of , look forward to, listen to等。
