UNIT 6 Period Ⅴ 单元语法（word教参）-【优化探究】2021-2022学年新教材高中英语必修第二册配套教参（北师大版）

Period Ⅴ　单元语法 授课提示：对应学生用书第82页 “介词＋关系代词”引导的定语从句 ①However，after a year or so in which they became more serious about their work，the Monkees started to play and sing their own songs like a real band. ②However，the next King of Prussia，Frederick William Ⅰ，to whom the amber room belonged，decided not to keep it. ③Later，they may give performances in pubs or clubs，for which they are paid in cash. ④They may start as a group of high­school students，for whom practising their music in someone's house is the first step to fame. [我的发现] 1．以上四个句子都使用了“介词＋关系代词”引导的定语从句。先行词若指物，那么介词后的关系代词用which；若指人，则用whom。 2．以上四个句子中，第①句是限制性定语从句，第②③④句是非限制性定语从句。 1．“介词＋关系代词”结构引导定语从句时，关系代词只能用which (指物) 或whom (指人)，即：介词＋which/whom，并且不能省略。 If you have anything on which you want my opinions，feel free to see me. 如果你们有什么事需要征求我的意见的话，随时来找我。 I took a photo of the students，among whom was seated a teacher. 我给这些学生拍了一张照片，他们中间坐着一位老师。 2．“介词＋which”在定语从句中作时间、地点、原因状语时，相当于关系副词when，where，why。 She still remembers the day on which (＝when) she won the prize. 她仍然记得自己获奖的那一天。 This is the house in which (＝where) I lived two years ago. 这是我两年前住过的房子。 We didn't know the reason for which (＝why) he refused our help. 我们不知道他拒绝我们帮助的原因。 [名师点津]　当定语从句中的谓语动词短语是固定搭配不可分割时，那么该动词短语中的介词不能前置，如listen to，look at，look for，look into，depend on，make use of，pay attention to，take care of等。 This is the pen which I'm looking for. 这是我正在找的那支钢笔。 3．介词前有时加名词、数词等，构成“名词/数词/不定代词＋of which/whom”结构，在定语从句中作主语。 English is a language shared by several diverse cultures，each of which uses it differently. 英语是一种多元文化共享的语言，每一种文化都以不同的方式使用它。 I collected some books，the covers of which (＝whose covers/of which the covers) are yellow with years. 我收藏了一些书，它们的封面因年代久远都变黄了。 [名师点津]　“介词＋关系代词(which/whom)”是定语从句重点和难点，因为很多同学不知道该如何确定关系代词(which/whom)前面的介词。下面介绍一个办法：“一先，二动，三意义”。 “一先”，即根据先行词来确定介词。 The factory in which I'm working mainly produces computers. 我工作所在的工厂主要生产电脑。 (in which代替in the factory，在工厂里用介词in。) “二动”，即根据定语从句中的谓语动词来确定介词。 In the dark street there wasn't a single person to whom she could turn
