定语从句易混淆概念梳理

高一英语,定语从句易混淆概念梳理,学生常混淆的定语从句概念：,1.先行词2.引导词3.先行词和引导词的关系4.先行词和介词+引导词的关系,只要弄清楚以上四个概念问题，定语从句的所有问题基本上都可以迎刃而解啦！,1.先行词解题关键：先行词是定语从句所修饰的名词(或代词)。如：Heworksonthefarmhisparentsleftforhim.,记住：是名词哦！,that/which/不填,2.引导词引导词分为：关系代词和关系副词关系代词：who,whom,which,that,whose关系副词：where,when,why解题关键：定语从句缺主/宾/表语的（whose除外），选一关系代词作引导词（先行词=关系代词）。定语从句句子主干完整但可加状语的，选一关系副词作引导词。（先行词=介词+关系代词）如：IlikethefilmChaplinestarredin.ThereasonIwaslateisthatIcouldnotcatchthebus.,that,why,前面点1和点2两个概念为下面点3和点4两个至关重要的问题奠定了非常坚实和重要的基础。3.先行词和引导词的关系解题关键：把先行词代入到定语从句中，由先行词在定语从句中所作的成分来决定引导词的选用。如：Iwillrememberthedaywewenttovisittheoldsoilders.Iwillgototheairportonthedatemyfriendtoldme.,when,which/that/不填,4.先行词和介词+引导词的关系1）作为令先行词和定语从句接轨的“螺丝钉”而凭空“变”出来的。如：Sheisbusythesedayssheispreparingforanimportanttest.2）定语从句本身带有的，“借调”到引导词前。即：介词+关系代词如：Thepersonmyfatheristalkingismyteacher.解题关键：一是可以通过整个句子整体含义来判断,结合生活实际来“变”出一个“螺丝钉”介词安装上去；再则看从句谓语部分缺少什么介词(习惯搭配).注：缺介词就会改变意思的动词短语不可把介词提前。,问：介词从哪里来？,which,during,whom,to,1.Ishallneverforgetthoseyears_Ilivedinthefarm_youvisitedlastweek.A.when,whereB.which,whichC.when,whichD.that,where2.Inthedarkstreet,therewasntasingleperson_shecouldturnforhelp.A.towhomB.whoC.fromwhomD.that3.Hebuiltatelescope_hecouldstudythestars.A.inwhichB.withthatC.throughwhichD.byit4.Thelittlegirlforwhomthepolicemenwerelookinghasbeenfound.(),F,更正：Thelittlegirlwhomthepolicemenwerelookingforhasbeenfound.,总结：,定语从句的内容纷繁复杂，多彩缤纷，但是当我们透过种种现象看本质的时候，会发现定语从句几乎所有的问
