名词性从句与定语从句的区别

名词性从句在句子中做了一个成分,可以是主语、宾语……如果缺少了它,句子就不完整了。

如:What he wants to tell us is not clear. What he wants to tell us 就是名词性从句,在句子中做主语成分。如果少了它,句子就变成is not clear.就不是一个完整句子。

定语从句起修饰作用的,修饰句子中的某个成分。去掉它,句子仍然完整。如:Those people who are bored to death are pathetic. who are bored to death 就是定语从句,修饰those people 没了它,句子变为those people are pathetic.有主语、be动词、状语,是完整的结构。

名词性从句(非定语从句!)中which与what的区别

what可以是感吧词,形容词,副词,名词,代词;

which 只能是形容词和代词

What subject do you like?你喜欢什么事物?什么样的,为形容词;

Which subject do you like?你喜欢哪一种的事物?哪个(种)的,也为形容词.

只有相同词性才可以替换.

1,what 表示什么,what class are you in 指你在什么班,比如艺术班,书法班,数学班,等等,但which class are you in指的是你在哪一个班,问话的人事先知道有哪些班,然后问对方在那个,或一班,二班,或艺术、数学其中的班。二者在这个用法上的区别不是特别大。有时候可以换用,根据习惯用。

2,当这个句子用在非限制性从句中时,就必须用which,而不是what.比如,the class 4, which class are you in, is a goog class.

【1】做疑问词,what是指“什么”例如:What's your name?,which是指“哪一个物体”Which pen do you want.。

【2】which一般可做定语从句连接词,例如:This is the pen which I want. what 一般可做名词性从句的引导词。例如:What you said is true.

定语从句和名词性从句的区别

第一,定语从句有先行词,且先行词可以放入后面的从句中使从句完整;

名词性从句中的主语从句、表语从句和宾语从句没有先行词,同位语从句有先行词但在从句中不做成分。

e.g. The news that they told me excited me.(the news可以放入从句中,使句子完整,即they told me the news)

The news that our team won excited me.(the news无法放入从句中,所以是同位语从句)

第二,在句子中起名词作用的句子叫名词从句(Noun Clauses)。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

定语从句是由关系代词和关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,定语从句分为限定性和非限定性从句两种。

第三,最关键也是最重要的区别:

1.名词性从句和定语从句的最本质的不同点在于,前者在句子中做名词,而后者相当于形容词,修饰或限制名词或代词。名词性从句由that引导时,通常不充当从句的句子成分,故that可省去。但定语从句由that引导时,如在从句中充当主语时,则that不能省去。

2.使用中最大的区别:定语从句由于在句子中只作定语,故去掉它,整个句子还完整,就像普通的句子去掉一个定语不影响原句的完整性一样。但名词性从句由于它们充当的是句子的骨干成分(主语,宾语或表语),故去掉它们,原句就不通了。如上面的A句,去掉了主语从句That he has become a rich man ,原句变成is known to all in our town。就失去了完整性。而B句,去掉定语从句部分that is on the desk后,原句变成The pen is mine还是通的。

The reason ______he gave for not coming was ______ his mother wouldn't allow him to.

A. for which; that

B. which; because

C. why; that

D. which; that选d为什么啊请问达了为什么不用why

why是引导定语从句的关系副词,which是关系代词,定语从句后面该用关系副词还是关系代词,这样来判断,当先行词是reason,我们有三个后选项:why,which/that. 再判断关系词在从句中的成分,当关系词在从句中充当主语或宾语时,用which/that,当先行词在从句中充当状语时用why引导。此句中从句he gave后缺少宾语, 所以用which充当gave的宾语。

第二个空在be动词之后是表语从句,表语从句可有what 和that引导,what 引导时,它在句子中充当成分,而that引导时不充当成分,仅作引导词,此句表语从句中主谓宾都在不缺少成分,所以用that.

This is the reason ____________ he gave us for carrying out the plan.

A. why

B. because

C. which

D. what

答案是C 我选了A

This is the reason___he didn't come to the meeting.

a,in which b,with which c,that d,for which

The reason why 要接定语从句,而the reason for 后接一个名词性的结构,二者不能完全一致。但当for后是一个完整的句子时,可用for which。

1. The reason( for the change) is lack of money, pure and simple.

进行更改的原因就是缺少经费.

1. The reason for the change is lack of money, pure and simple.

进行更改的原因就是缺少经费.

2. That is one reason for my having entered you at Riverview.

这是我让你上河景中学的原因之一。

3. The reason (for his success) is not far to seek he worked hard.

他成功的原因不难找,那就是他勤奋工作。

the reason for +短语

the reason why + 从句

最新定语从句中的that和which的区别

定语从句中的that和which的区别: that和which在从句里都可以做宾语和主语,做宾语时可以省略。在定语从句中,有种说法叫"关宾省",意思是关系代词在限制性定语从句中作宾语可以省略,不管是that,which,还是whom。但是which能引导非限制性定语从句,that则不行。 只能用that的几种情况: 1. 当先行词为all, much, little, none及由any, every, some, no所构成的复合不定代词时。We should do all that is useful to the people. Please tell me anything that you know about the matter. 2. 当先行词被any, few, little, no, all, much, some等词修饰时。 You can take any seat that is free.

Which is the star that is nearer to the earth? 8. 当先行词为主句表语或关系代词为从句表语时。 That’s a good book that will help you a lot. Our school is no longer the place that it used to be. 9. 先行词为time时,当time表示次数,引导词用that, 可省略。当表示时间,可用that 或when引导,都可省略。 I do remember the first time(that) I had ever heard the sweetest voice in the world. I did't remember the exact time (when/that)I arrived in Shanghai last month. 只能使用which的情况: 1. 在“介词+关系代词”结构中,关系代词必须用which。 The house in which we live is very large. This is the reference book(参考书)of which the teacher is speaking. 注意:如果介词不放在修饰事物的限定性定语从句的句首,which就可换为that。 This is the question which/that we’ve had so much discussion about. =This is the question about which we’ve had so much discussion. 2. 先行词为“those+表事物的复数名词”时,关系代词通常只用which而不用that。 You should grasp well those skills which may be used in the future work.

We should do all that is useful to the people. 2. There's nothing that can be said about it. 3.

定语从句中where和which的区别

定语从句中where和which的区别

定语从句中where和which的区别 1.This is the factory_________we visited yesterday. 2.This is the stable__________Jesus Chirst was born. 1,which 2.where 分析:关键是看从句中的动词。如果是及物动词(顾名思义,就是必须要接物做宾语的动词,或能用做被动的动词),则表明从句缺宾语,修饰人用who/whom/that。修饰物用that/which. 如动词是不及物(顾名思义就是不需要接物做宾语的或要接宾语时前面必须要加介词的,即用介宾的动词),则说明从句不缺宾语,可能是状语(或介宾)。表地点用where.时间用when. 如题1:从句的动词是visit,我们说参观某个地方说:visit some place。而不说visit in the place所以visit是及物动词。所以缺宾语,修饰物故用which. 如题2,我们说出生于某地用be born in,如:i was born in beijing 而不说i was born

beijing.故说明born 后不直接跟宾语,应用介宾,或关系副词(where/when)所以此处填in which 也是正确的。 所以在平时的练习中应注意动词的及物于不及物性1这是解决这类题的关键之一。扩展练习: 1.These are the days ____ I spent with my mom. (when) 2.These are the times _____ I experienced .(which) 英语定语从句that ,where ,which 的区别 例如:(1) I love places ____ the people are really fridendy A.that B.which C.where D.who (2) This is the place ____ I have ever visited there B.whom C.he D.which (3).This is the house ____ I want to buy A.In which B.that C.what D.that (4)this is the museum ____ we visited last year A.where B. in which C.which D.in that

(完整版)as和which引导非限制性定语从句的区别

As与which引导非限定性定语从句辨析 1.as引导非限制性定语从句,只代表主语或主句的一部分所表达的意思(不能指代某个名词或代词),可以放在主句前,后或中间,在从句中作主语或宾语、例如: As is known to all, he is the best student in our class.
