1、..英语语法：名词性从句常见错误例析　1.【误】Hewillcomebacksurprisesallofus.【正】Thathewillcomebacksurprisesallofus.　　【析】that引导名词性从句时,尽管无意义也不充当成分,但除了在动词后引导单个宾语从句时可省略外,其它情况不能省略。2.【误】Thathereallymeansiswhathedoesn’tagreewithus.【正】Whathereallymeansisthathedoesn’tagreewithus.【析】that和what均可引导名词性从句，区别在于：what在名

2、词性从句中作主语、宾语或表语，而that在名词性从句中不作任何成分，只起连接作用。误句的主语从句应该用what作means的宾语，表语从句中应该用that，that在从句中不作任何成分。　　3.【误】Thenewswhichourteamhadwonpleasedeveryone.　　【正】Thenewsthatourteamhadwonpleasedeveryone.　　【析】which在此句中不充当成分，说明从句不是定语从句而是同位语从句。同位语从句不能用which引导，故改为that。　　4.【误】Thereasonwhyhefailedintheex

3、amwasbecausehewastoocareless.　　【正】Thereasonwhyhefailedintheexamwasthathewastoocareless.　　【析】主语为reason时，引导表语从句的关联词一般用that，不用because，构成Thereasonwhy/forwhich/that/for...isthat..句型。because引导名词性从句只用于It/This/Thatisbecause...结构。　　5.【误】Itisunknownthatwherewewillhavethemeeting.　　【正】Itisunkn

4、ownwherewewillhavethemeeting.【析】名词性从句一般只能用一个引导词，连接词that与连接副词不可并用。　　6.【误】Theproblemiswhenwillhecomeback.【正】Theproblemiswhenhewillcomeback.　　【析】名词性从句应该用陈述句语序，即“引导词+主语+谓语”。　　7.【误】CouldyoutellmewhichwasthewaytotheScienceMuseum?　　【正】CouldyoutellmewhichisthewaytotheScienceMuseum?word教育资料

5、..　　【析】当主句为过去时态的时候，宾语从句中要用过去的某种时态。但该句中的could不是表示过去，而是表示一种委婉的语气，故宾语从句中的谓语动词应用一般时态。　　8.【误】Ifheisanengineerisunknown.【正】Whetherheisanengineerisunknown.　　【析】if不能用来引导主语从句，在表示“是否”这一意义时要用whether。　　9.【误】IhavebeenworryingaboutifIhavehurtherfeelings.　　【正】IhavebeenworryingaboutwhetherIhavehur

6、therfeelings.　　【析】if和whether引导动词后的宾语从句时可互换。但介词后的宾语从句及主语从句、表语从句、同位语从句只能用whether引导。　　10.【误】WhatheneedsareenoughtimeandwhatIneedisenoughbooks.　　【正】WhatheneedsisenoughtimeandwhatIneedareenoughbooks.　　【析】名词性从句作主语时，谓语动词常用单数。但what引导主语从句时，若表语为单数名词或不可数名词，则谓语动词用单数；若表语为可数名词复数，则谓语动词常用复数。11.【误】

7、Nomatterwhocomestovisittheexhi-bitioniswelcome.【正】Whoevercomestovisittheexhibitioniswelcome.【析】“Nomatter+疑问词”结构只能引导让步状语从句，“wh-+ever”既可引导让步状语从句，也可引导名词性从句。12.【误】I’llmakeknowntoallthatyouwerenothonest.【正】I’llmakeitknowntoallthatyouwerenothonest.【析】当宾语从句前有形容词或名词作宾补时，须用it作形式宾语，而将真正的宾语从句

8、后置。其句式为：主语+动词+形式宾语it+宾补（形容
