which的常見用法歸類
which的常見用法歸類
which的用法是英語學習中的一個難點，下面學習啦小編給大家歸納它的相關用法，希望能對大家有所幫助：
1、在問句中作疑問代詞,在名詞從句中作為連接代詞用,其含義為“哪兒,哪些”.
2、如果非限制性定語從句的先行詞不是指主句內容,而是指具體的人、時間、地點,則不用which.
3、在后置的非限制性定語從句中代替上文出現(xiàn)的事物或者情況(單數(shù)或復數(shù)).
下面主要講解一下在定語從句中的常見用法：
一、關系代詞that和which在定語從句中作主語和賓語,放在先行詞和定語從句之間,起聯(lián)系作用,指物時,一般情況下可互換,如：
A plane is machine that/which can fly(that/which指物,做主語)
The man that works in this room is a chemist(that 指人,作主語)
Here is the pen that/which you lost yesterday(that/which 指物作賓語)
He is the most careful boy that I know(that指人,作賓語)
二、關系代詞在主語從句中作主語時,從句的謂語動詞的人稱和數(shù)須賀先行詞一致.
wheat is a plant that/which is grown in the north of China.
三、that、which在從句中作主語時,不能省略.作賓語時在口語中和非正式問題中經常省略.如上例1和3中的that、which都可省略.
四、在定語從句中,關系代詞that和which指物時,一般沒有區(qū)別,但下列幾種情況中不能互換：
1、只能用that的情況：
a、先行詞被序數(shù)詞所修飾時：
The first thing (that) we should do is to work out a plan.
b、先行詞被形容詞最高級所修飾時：
This is one of the most exciting football games(that)I have ever seen.
The nanjing yangtse river bridge is the longest bridge (that) they ever seen.
c、先行詞為all、everything、nothing、anything、little等不定代詞(something后也可以用which)：
Is there anything (that) I can do for you town?
That is all (that) I Know.
d、 在“the time when”等結構和某些事件狀語中,when常被that代替,而且that往往被省略.
I may leave here any time I want to.
During the time I was there I visited him twice.
e、當先行詞中即有人又有物時：
The man and the car (that)you want to see are all here .你想見的人和車斗在這.
f、that 可指人,which則不能.
g、 way 后面可根由that引導的定語從句,但that一般都省略：
That was the way she looked after us.
who is the man that is reading new paper over there?
h、先行詞被形容詞最高級修飾時：
This is the only thing (that) we can do now.
He gave me the same pen (that) were written by Lu Xun?
2、在下列情況下,只能用which
a、放在介詞后面做介詞定語時：
This is the question about which we’ve had so much discussion
但是,如果把介詞放在從句后部.這時which 就可換為that并常省略,如上例可以改為：
This is the question that we are had so much discussion about.
b、在非限定性定語從句,無論指物指人,都不能用that,指物時,只能用which和其他關系代詞,如：
All the books there,which have beautiful pictures in them,were written by him.
