名词性从句-一轮复习总结.pptVIP

话题·微型写作 知识·巧记速记 重点·突破方法 （一） 名词性从句的结构和功能 名词性从句主要有四种从句结构： 以that引导的从句； 以whether/ if引导的从句； 以特殊疑问词引导的从句； 以what或wh-ever等连接代词引导的名词性关系从句。 此外，as if/ as though也可引导表语从句。 （二）名词性从句的连接词 引导名词性从句的连接词有：从属连词、连接代词和连接副词。 1. 从属连词：that(本身无意义)，whether(是否)，if(是否)。只起连接作用，在从句中不作任何成分。 2. 连接代词：who, whom, whose, which, what, whatever, whoever等。它们除起连接作用外，还可在从句中充当主语、宾语、定语、表语等成分。 3. 连接副词： when(＝the time when什么时候，何时) where(＝the place where什么地方，何地) how(＝the way that/in which怎样，以……方式，如何) why（＝the reason why为什么)。 它们除起连接作用，还在从句中作状语。 使用连接词时的注意事项： 连接代词和连接副词一般都表疑问，但what, when和where等连接词有两种含义，一种表示疑问，一种表示陈述。表陈述时，相当于the thing that, the time when, the place where, 常意为“……的人/事”、“……的时间”、“……的地点”等。 e.g. This is where he once lived. This is what I want to know. That was when he did the experiment. 考点一 主语从句 1.主语从句在复合句中作主句的主语。引导主语从句的词如下： who, that, which, what, when, where, how, whether，why, whoever, whichever, whatever等。 考点一 主语从句 1._____we are invited to a concert this evening is good news to us. ＝It is good news to us _____ we are invited to a concert this evening. 2._____ will go to the energy conference is not important. 3._____ he needs are books. 4._____ they will come hasnt been made public.
