在下列情況下要用 which:
①在非限制性定語從句中.
【例】
She made great progress and won a prize,which gave us a surprise.她取得了很大進步并獲得了獎金,這使我們很驚訝.
Mrs Tailor's cat,which was very old,became ill and then died.泰勒太太的貓很老了,生病以后就死了.
②在介詞+關(guān)系代詞引導(dǎo)的定語從句,必須使用which.
【例】
This is the knife with which John hurt somebody.
這就是約翰傷人的那把刀.
He built a telescope through which he could see things far away.他建了一個望遠鏡,通過它,他可以看見遠處的東西.
③當先行詞本身是that時,使用which.
【例】
The predicate is that which is said of the subject.
謂語是對主語的陳述.
④當關(guān)系詞后面有插入語時.
【例】
Here is the ALD which,as I have told you,is a great help to you.這是《牛津高級學者字典》,正如我告訴你的那樣,對你會有很大的幫助.
⑤當非限制性定語從句的謂語是一個復(fù)合結(jié)構(gòu)時,常使用which引導(dǎo).
【例】
Little Bob always tells a lie,which his parents find strange.
小鮑勃總是說謊,這使他的父母感到很吃驚.
謂語由動詞構(gòu)成,依據(jù)其在句中繁簡程度可把謂語分為簡單謂語和復(fù)合謂語兩類.
復(fù)合謂語可分為兩種情況：
第一種是由情態(tài)動詞,助動詞+不帶to的動詞不定式構(gòu)成的復(fù)合謂語：
What does this word mean?
I won’t do it again.
I’ll go and move away the bag of rice with Lin Tao.
You’d better catch a bus.
第二種是由連系動詞+表語構(gòu)成的復(fù)合謂語.例如：
You look the same.
We are all here.
The weather gets wamer,and the days get longer.
Keep quite and listen to me.
He looked worried.
We have to be up early in the moming.
Is Bill in?
School Is over.Let’s go home.
My pen is in my bag.
I feel terrible.
I* fell tried all the time.
He seemed rather tired last night.
