定语从句关系代词that与which的用法区别有哪些

Answer 1

1.that既可代表事物也可代表人,which代表事物；它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语则不能省略.而且,如果which在从句中作“不及物动词＋介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置
2.which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢
3.代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括当先行词是anything,everything,nothing ,few,all,none,little,some等代词时,或者是由every,any,all,some,no,little,few,much等修饰时等,这时的that常被省略
4.who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语
5.where是关系副词,用来表示地点的定语从句
6.when引导定语从句表示时间〔注〕值得一提的是,表示时间“time"一词的定语从句只用when引导,有时不用任何关系代词,当然也不用that引导
By the time you arrive in London,we will have stayed there for two weeks.I still remember the first time I met her.Each time he goes to business trip,he brings a lot of living necessities,such as towers,soap,toothbrush etc.
7.whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物,当它引导的从句修饰物体时,可以与 of which 调换,表达的意思一样.
8.当从句的逻辑主语是some,any,no,somebody,anybody,nobody,something,anything,everything或nothing时,常用there is来引导
There is somebody here who wants to speak to you.这里有人要和你说话.
编辑本段（二）非限定性定语从句
非限定性定语从句的作用是对所修饰的成分作进一步说明,通常是引导词和先行词之间用逗号隔开,将从句拿掉后其他部分仍可成立
1.which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
2.当先行词是专有名词或物主代词和指示代词所修饰时,其后的定语从句通常是非限制性的,例如：
Charles Smith,who was my former teacher,retired last year.查理·史密斯去年退休了,他曾经是我的老师.
My house,which I bought last year,has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园.
This novel,which I have read three times,is very touching.这本小说很动人,我已经读了三遍.
3.非限制性定语从句还能将整个主句作为先行词,对其进行修饰,这时从句谓语动词要用第三人称单数,例如：
He seems not to have grasped what I meant,wh

That和which用法的区别：
一下情况用that:
1.当先行词是指物的不定代词all, little, few, much, everything, anything, nothing, some,none等
I want to tell you something that you do not know.
2.当先行词有以下the only, the right, the very the last及,any,some ,no, any, just, few, little 等不定代词修饰时:
This is the very book that she is looking for.
3.当先行词是形容词或先行词由形容词最高级修饰时：
This is the fast train that will leave for Beijing. This is the most interesting film that she has ever seen.
4.当先行词是序数词或由序数词修饰时：
This train is the last that will go to Shanghai. This is the last train that will go to Shanghai.
5.当先行词即指人又指物的时候：
I know the persons and things that you are talking about.
6.当主句的疑问词是who或which时:
Who is the man that won the first prize? Which is the bike that you lost.
7.当先行词是主句表语，关系代词又是定语从句表语时：
Shanghai is no longer the city as it used to be.
8.两个从句，一个用了which,另一个就行that
They built up a small factory, which produced things that could pollution.
9.在there be 句式中，关系词作主语时
There is a seat that is still available.
10. 介词+which， You can find a book from which you can learn a lot.
11. 在非限制性定语从句里只能用which，不能用that。
