高中英语语法之定语从句课件.pptVIP

运用定语从句必须注意三点：由关系代词或关系副词所替代的成分在从句中不能再重复出现；定语从句和简单句一样，也要求句子结构既正确又完整；从句用陈述语序。 They are my brothers. I like them very much. They are my brothers whom I like them very much. They are my brothers whom I like very much. 关系代词和关系副词的选择： 分析定语从句的成分，若从句中缺主语或宾语，则必须用关系代词（that / who / whom / which）; 若从句缺少状语，则用关系副词（when / where / why） This is the place ______I once lived. This is the place _____ I once visited. I’ll never forget the days _____I worked with him. I’ll never forget the days _____ I spent with him. The reason ______ he gave us was unacceptable. The reason ______ he gave us so many things was unknown. where that / which when which/that which/that why 一、关系代词的考查 (一)下列情况中常用that引导定语从句，不用which 1.当先行词是all， everything，nothing， something， much， little，few等不定代词时。 There is nothing that can prevent him from doing it. 没有什么能阻止他干那件事。 2.当先行词被序数词修饰时。 The first place that they visited was Elephant Trunk Hill.他们所参观的第一个地方是象鼻山。 3.当先行词被形容词最高级修饰时。 This is the best film that I have ever seen. 这部电影是我看过的最好的一部. 4.当先行词被the very，the only，the same等词修饰时。 This is the very dictionary that I want to buy. 这正是我要买的词典。 5.当主句已有who，which等疑问代词时。 Who is the man that is standing by the gate？ 站在门边的那个人是谁？ 6.当先行词既有人也有物时。 They talked about the persons and things that they remembered at school. 他们讨论他们记得的学校里的人和事。 (五)whose引导定语从句时在从句中作定语，可以指人也可以指物,指物时whose+ n= n +of + which I like to live in a house, whose window faces to the east. = I like to live in a house, the window of which faces to the east. 我喜欢住在窗子向东开的房子里。 (六)as和which引导非限制性定语从句的异同 1.as和which都可以在定语从句中作主语或宾语，代指前面整个句子，从句谓语动词用单数。 He is from the south，as/which we can know from his accent.他是南方人，我们可以从他的口音上知道。 2.as引导的非限制性定语从句可放句首，句中，句末， which 引导的非限制性定语从句只能放句末。 3.as有“正如...；就像...”的意思，which没有 二、关系副词的考查 (一)关系副词在定语从句中作状语，when指时间，where指地点(抽象的地点名词：stage(事情发展的阶段),situation, point, case) why指原因(先行词只有reason)，在定语从句中分别作时间状语、地点状语、原因状语 I dont know the reason why she looks unhappy
