名词性从句复习

高一英语Module3Unit1GrammarandusageNounclauses

在复合句中起名词作用的从句叫名词从句(NounClauses)。名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。名词从句名词性从句在功能上相当于名词Hisjobisimportant.Whathedoesisimportant.主语Thisishisjob.Thisiswhathedoeseveryday.表语｛｛Idon’tlikehisjob.Idon’tlikewhathedoeseveryday.宾语Idon’tknowabouttheman,Mr.White.Idon’tknowaboutthefactthatheisateacher.同位语｛｛名词性从句考点归纳一、名词性从句的语序1)名词性从句的构成有两种a.That+陈述句+Thatlighttravelsinstraightlinesisknowntoall.b.疑问词+句子的剩余成分

idea,news,information,order,belief,suggestion,advice等；3.连接词通常是that,也可根据含义选用

whether,what,when,where等来引导同位语从句。Ihavenoidea_____hecomesfrom.

5.Ihavesomedoubt________hewillwin.thatwhether同位语从句和定语从句的区别1.定语从句是先行词的修饰语，它不涉及先行词的具体内容。定语从句中that不但起连接作用，而且在定语从句中充当一个句子成分，充当从句的宾语成分时可省略。2.同位语从句对中心词的内容作进一步的解释和说明，表明中心词的具体内容。引导同位语从句的that

在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略。1.Weexpressedthehopethattheyhadexpressed.2.WeexpressedthehopethattheywouldcometoChinaagain.AttributiveorAppositive?

Hetoldme_________________________________.他说他已离开家乡十年了。
