高一英语 定语从句易混同概念梳理第1页学生常混同定语从句概念：1.先行词2.引导词3.先行词和引导词关系4.先行词和介词+引导词关系只要搞清楚以上四个概念问题，定语从句只要搞清楚以上四个概念问题，定语从句全部问题基本上都能够迎刃而解啦！全部问题基本上都能够迎刃而解啦！第2页1.先行词先行词解题关键：解题关键：先行词是定语从句所修饰先行词是定语从句所修饰名词名词(或代词或代词)。如：如：He works on the farm his parents left for him.that/which/不填不填第3页2.引导词引导词引导词分为：关系代词和关系副词引导词分为：关系代词和关系副词关系代词：关系代词：who,whom,which,that,whose关系副词：关系副词：where,when,why解题关键解题关键：定语从句缺：定语从句缺主主/宾宾/表语表语（whose除除外），选一关系代词作引导词（外），选一关系代词作引导词（先行词先行词=关系关系代词代词）。）。定语从句句子主干完整但可加定语从句句子主干完整但可加状语状语，选一关系，选一关系副词作引导词。（副词作引导词。（先行词先行词=介词介词+关系代词关系代词）如：如：I like the film Chapline starred in.The reason I was late is that I could not catch the bus.thatwhy第4页前面点前面点1和点和点2两个概念为下面点两个概念为下面点3和点和点4两两个至关主要问题奠定了非常坚实和主要基础。个至关主要问题奠定了非常坚实和主要基础。3.先行词和引导词关系先行词和引导词关系解题关键解题关键：把先行词代入到定语从句中，由：把先行词代入到定语从句中，由先行词在定语从句中所作成份来决定引导词先行词在定语从句中所作成份来决定引导词选取。选取。如：如：I will remember the day we went to visit the old soilders.I will go to the airport on the date my friend told me.whenwhich/that/不填不填第5页4.先行词和介词先行词和介词+引导词关系引导词关系1）作为令先行词和定语从句接轨）作为令先行词和定语从句接轨“螺丝钉螺丝钉”而凭空而凭空“变变”出来。出来。如：如：She is busy these days she is preparing for an important test.2）定语从句本身带有，）定语从句本身带有，“借调借调”到引导词前。即：到引导词前。即：介词介词+关系代词关系代词如：如：The person my father is talking is my teacher.解题关键：解题关键：一是能够经过整个句子整体含义来判断一是能够经过整个句子整体含义来判断,结合生活实际来结合生活实际来“变变”出一个出一个“螺丝钉螺丝钉”介词安装介词安装上去；再则看从句谓语部分缺乏什么介词上去；再则看从句谓语部分缺乏什么介词(习惯搭配习惯搭配).注注：缺介词就会改变意思动词短语不可把介词提前。：缺介词就会改变意思动词短语不可把介词提前。whichduringwhomto第6页1.I shall never forget those years _ I lived in the farm _ you visited last week.A.when,where B.which,which C.when,which D.that,where2.In the dark street,there wasnt a single person _ she could turn for help.A.to whom B.who C.from whom D.that3.He built a telescope_he could study the stars.A.in which B.with that C.through which D.by it 4.The little girl for whom the policemen were looking has been found.()F更正：更正：The little girl whom the policemen were looking for has been found.第7页总结：总结：定语从句内容纷繁复杂，多彩缤纷，不过当我们透过种种现象看本质时候，会发觉定语从句几乎全部问题都是围绕以上这几个概念关系展开。所以，只要我们理顺了他们，定语从句其它细节问题，都不成问题啦！同学们，你们都掌握了吗？第8页第9页
