1、高中语法精讲名词性从句高中语法精讲名词性从句了解这样的从句前,我们先回忆下英语中常见的句子成分:了解这样的从句前,我们先回忆下英语中常见的句子成分:主语谓语宾语表语定语状语补语同位语(再念叨一遍:理解英语中的句子成分对于长难句的理解是很有用的,阅读能力会进步飞快)那么问题来了:这些句子成分中,哪些可能是名词呢?那么问题来了:这些句子成分中,哪些可能是名词呢?换句话说,名词能做哪些成分呢?换句话说,名词能做哪些成分呢?主语,宾语,表语和同位语是名词最中意的位置啦!主语,宾语,表语和同位语是名词最中意的位置啦!如果把名词改为句子,那不就是从句了吗?有名词性功能的句子我们就给个高大上的名字如果把名词
2、改为句子,那不就是从句了吗?有名词性功能的句子我们就给个高大上的名字名词性从句:名词性从句:包括主语从句包括主语从句 宾语从句宾语从句 表语从句表语从句 同位语从句同位语从句来看个句子:Playing football is interesting.这里动名词做主语。那按刚才说的,名词改为句子:That we play football together is interesting.that 引导的从句 that we play football together 在句子中是整个作了主语,所以这句就是主语从句一、名词性从句一、名词性从句1 1、名词性从句中的易错点、名词性从句中的易错点(1
3、1)thatthat 的用法。的用法。主语从句、表语从句、同位语从句中用主语从句、表语从句、同位语从句中用 thatthat 但不能省略。如:但不能省略。如:That they are good at English is known to us all.The problem is that we dont have enough money.She expressed the hope that they would come to China one day.宾语从句中的连接词宾语从句中的连接词 thatthat 有时可省有时又不可省,有时可省有时又不可省,在以下几种情况中在以下几种情况
4、中 thatthat 不能省略:不能省略:(A)当 that 从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时,that 不可省略;(B)当 that 从句与另一名词性从句并列作宾语时,that 不能省;(C)当 that 作介词宾语时,that 不可省掉。如:He judged that,because he was a child,he did not understandwineEveryone knew what happened and that she was worried.The reason lies in that she works harder than th
5、e others do.thatthat 从句作主语和宾语时,可以用从句作主语和宾语时,可以用 it it 来替换成以下几种结构表达。来替换成以下几种结构表达。(A)It is clear/certain/likely/true/surprising that(B)It is a pity/shame/good idea/no wonderthat.(C)It is said/reported/believed/known/thought/suggested that (D)It seems/happensthat。如:It happened that I went out last nigh
6、t.It is said that China will win in the World Cup.thatthat 和和 whatwhat 的区别。的区别。that 引导名词性从句时,在主从句中不以当任何句子成分,也没有任何含义;而 what引导名词性从句时,在主从句中都要充当一定的句子成分,what 可以分解成定语从句中的先行词+关系代词即常说的先行词+that。如:Its shame that he has made such a mistake.Do what he says.同位语从句与定语从句中同位语从句与定语从句中 thatthat 的区别。的区别。同位语从句中的连词 that
7、只起连接作用,在从句中不担当任何句子成分;而定语从句中的关系代词 that 在句中做宾语或主语,宾语与先行词有修饰关系。如果句子是同位语从句,就应用连词 that 而不能用 which.同位语从句一般放在表具体含义的名词后解释名词的含义或内容,如以下名词:news、fact、suggestion、truth、plan、belief、doubt、possibility、idea等,而定语从句只是对先行词的限定和修饰。如:They expressed the hope that they would come to visit China again.(同位语从句)The hope she exp
8、ressed is that they would come to visit China again.(定语从句)(2 2)whetherwhether 和和 if if 的用法。的用法。whether 和 if 在宾语从句中可以互换,但是作介词宾语时连接词一般用whether。如:It all depends on whether they will come back.后面直接跟 or not 时用 whether。如:I didnt know whether or not he hadarrived in Wuhan.主语从句表语从句中只能用whether。如:Whether the
9、meeting will be put off has not been decided yet.The question is whether they have so much money.whether 可以引导同位语从句,用以说明前面的名词的内容,if 不能。如:We ought to discuss carefully the question whether we can doit or not.whether 常与 or 连用表示一种选择,if 不能这样用;whether 也可与动词不定式连用但 if 不能。如:The question of whether they are m
10、ale or female is not impor-tant.I have not decided whetherto go or not.间接引语位于句首时或者是间接引语提前时用whether 不用 if。如:Thank you,but whether Ill be free Im not sure at the moment.whether 可引导一个让步状语从句表示“不管”、“无论”,而 if 不能。如:Whether he comes or not,we will begin our party on time.(3 3)疑问词)疑问词+ever+ever 和和 no matter+
11、no matter+疑问词的区别。疑问词的区别。疑问词+ever 可引导名词性从句,在主从句中要充当一定的部分。如:Whoever breaks the rule must be punished.You can choose whatever you like in the shop.疑问词+ever 还可引导让步状语从句。如:Whoever breaks the rule,he must be punished,Whatever you do,you must do it well.no matter+疑问词只能引导让步状语从句。如:No matter what you do,you mu
12、st do it well.No matter who breaks the rule,he must be punished.(4 4)whenwhen 和和 wherewhere 引导的同位语从句与定语从句的区别。引导的同位语从句与定语从句的区别。when 和 where 前面的名词若是表示时间、地点的名词,则 when 和 where 引导的是定语从句,否则则为同位语从句。如:They put forward the question where they could get the money.This is the place where the accident happened.
13、2 2、名词性从句中主句和从句的时态一致、名词性从句中主句和从句的时态一致(1)宾语从句中主句和从句的时态保持一致,但如果从句中表示提示的是客观现象,虽然主句是过去时态,从句仍用一般现在时。如:Hello,I didnt know you were in London.How long have you been here?The teacher told us that light travels at a very high speed.(2)主语从句作主语相当于单数第三人称作主语,谓语动词用单数,如果由and 连接两个或两个以上的主语从句作主语时,谓语动词用复数;由两个或多个连接词引导一
14、个主语从句,谓语动词用单数。如:When the meeting will begin has not been decided yet.When they will start and where they go have not been decided yet.When and where the meeting will begin has not been decided.3 3、名词性从句的词序、名词性从句的词序名词性从句在句中要用陈述句语序。如:He asked me what was the matter with me.Weve heard the news that wel
