關(guān)系代詞常在從句中擔(dān)任主語、賓語或表語等成分;關(guān)系副詞常在從句中擔(dān)任狀語。另外,在使用上面的這些關(guān)系詞時,有幾個問題值得我們注意:
首先,只能用whether而不能用if的情況
1)引導(dǎo)主語從句,例如:
Whether we'll make a loan for the project has not been decided .
�。ㄕ_)我們是否要為這個項目還沒有定下來。
OR:It has not been decided whether we'll make a loan for the project . (正確)
If we'll make a loan for the project has not been decided .(錯誤)
OR:It has not been decided if we'll make a loan for the project . (錯誤)
2)作介詞的賓語,例如:
I have no idea about whether I can raise the money for buying a car . (正確)
我不知道我是否能為買車籌措到資金。
I have no idea about if I can raise the money for buying a car . (錯誤)
3)后接不定式 ,例如:
He didn't know whether to go all himself first or wait for
her here.(正確)他不知道是他自己先去還是在這兒等她。
He didn't know if to go all himself or wait for her here . (錯誤)
(4)后接or not ,例如:
We wonder whether they'll come in time or not.(正確)
我們擔(dān)心他們會不會準(zhǔn)時到。
We wonder if they'll come in time or not . (錯誤)
其次,what引導(dǎo)的名詞從句表達(dá)的意思是"……所……的".這個"所怎么的"定義根據(jù)"從句謂語的動作意義"而定。例如:
I don't understand what you said.我不理解你所說的話。
What he needs is to practice more.他所需要的是勤于練習(xí)。
Money is what she is really after.金錢是她所真正追求的東西。
People have different ideas about what happiness means .
人們對于幸福的含義有不同見解。
最后,要了解 -ever = no matter ,用于表示強(qiáng)調(diào),意為"無論……".也就是說:
whatever = no matter what(無論什么)
whoever = no matter who(無論誰)
whichever = no matter which(無論那個)
whenever =no matter when (無論何時)
wherever = no matter where(無論何地)
however = no matter how (無論怎樣)
A 主語從句
用作主語的主謂結(jié)構(gòu)稱之為主語從句。例如:
Whether he'll come or not remains a question .
他是否會來依然是一個問題。
Whoever says that is not allowed .
無論誰這樣說都是不允許的。
That she reads English aloud every morning helps her a
lot in the improvement of her English study .
她每天早晨朗讀英文對提高她的英語學(xué)習(xí)起了很大的作用。
