賓語從句即指在主從復合句中用作賓語的從句。賓語從句通常由連詞that和whether (if)以及連接代詞或連接副詞引導。賓語從句的詞序要用陳述句詞序,不能用疑問句詞序。
(1) 用that引導。that只起引導詞作用,不充當句子成分,也沒有詞義,且通??梢允÷裕?/p>
We think (that) he will help us. 我們認為他會幫助我們。
He said (that) he was good at English. 他說他擅長英語。
I know (that) he is very busy. 我知道他很忙。
(2) 用if或whether引導。if和whether引導賓語從句,不充當句子成分,但有詞義,表示“是否”:
I don't know if [whether] he will come. 我不知道他是否會來。
She asked if [whether] that was enough. 她問那是否夠了。
I wonder whether [if] it is true. 我不知道是不是真的。
(3) 用連接代詞引導。常見的引導賓語從句的連接代詞有what, who, whom, which, whose等。此時要特別注意賓語從句用陳述句詞序,而不用疑問句詞序:
Ask him which he wants. 問他要哪一個。
She asked who would like to go. 她問誰愿意去。
Tell me whose wallet this is. 告訴我這是誰的錢包
【注】what引導賓語從句時,有時表示“什么”,有時表示“…所…的”。比較:
I asked what he needed. 你問他需要什么。
I gave him what he needed. 我給了他所需要的東西。
(4) 用連接副詞引導。常見的引導賓語從句的連接副詞有when, how, where, why等。此時要特別注意賓語從句用陳述句詞序,而不用疑問句詞序:
He knows where they live. 他知道他們住哪里。
Tell us how you are getting on now. 告訴我們你現(xiàn)在過得怎樣?
I can't tell you why she is crying. 我不能告訴你她為什么哭。
He didn't say when he would return. 他沒有說什么時候回來。
