英語的賓語從句不明白

賓語從句就是壹個句子在復合句中作動詞或介詞的賓語,在主句與從句之間有壹個引導詞,其結構為“主語+謂語動詞+引導詞+主語+謂語+其 它”。

主句 賓語從句

焦點壹:賓語從句的引導詞

1. 賓語從句具有陳述意義時用that引導。that無具體意思,不作任何成分,因此在口語或非正式文體中常常被省略。如:

She said (that) she would leave the book on his desk. 她說她會把那本書放在他的桌子上。

● 從句的主語是that時,that不能省略;主從句之間有插入語時,that不能省略;若出現兩個或兩個以上的that賓語從句,且由並列連詞連 接時,只有第壹個連詞that可以省去,其余保留。如:

It says here, on this card, that it was used in plays.卡片上寫著,它過去是演戲用的。

He thought that that was a washing machine. 他認為那是壹臺洗衣機。

My aunt said (that) she would come and that she would also bring her daughter. 我姑姑說她要來,還要帶她的女兒來。

2. 當賓語從句由壹般疑問句變化而來時,用if或whether來引導從句,意為“是否”。如:

Alice wanted to know if / whether her grandmother liked the bag. 艾麗斯想知道她祖母是否喜歡這個包。

在下列幾種情況下,只能用whether, 不能用if:

● 當or not 緊隨連詞之後時。如:

I don't know whether or not he will come on time. 我不知道他能否按時來。

● 從句用作介詞賓語時。如:

I am interested in whether he joined the army. 我對他是否入伍很感興趣。

● 在帶to的動詞不定式前。如:

She doesn't know whether to go to the cinema or to watch TV at home. 她不知道是去看電影還是在家看電視。

● 當賓語從句移至句首表強調時。如:

Whether this is true or not, I'm not sure. 這是否真實,我不敢肯定。

3. 賓語從句具有特殊疑問含義時用連接代(副)詞引導,它們在賓語從句中充當壹定成分,因此不能省略。如:

Did you hear what he said? 妳聽見他說的話了嗎?(作賓語)

I don't know whose that is. 我不知道那是誰的。(作表語)

Could you tell me how I get to the post office? 妳能告訴我到郵局怎麽走嗎?(作狀語)

焦點二:賓語從句的語序

無論賓語從句的主句是陳述句還是疑問句,也無論主從句間是什麽引導詞,賓語從句壹律用陳述語序,即“引導詞+主語+謂語+其它”。如:

Could you tell me? / Where does Wei Fang live?

→Could you tell me where Wei Fang lives?

● 當疑問代詞who, what等在從句中作主語時,語序本來就是陳述語序,故語序不再變化。如:

Who will give us a talk? Please tell us.

→Please tell us who will give us a talk.

焦點三:賓語從句的時態

● 如果主句是祈使句或主句中的謂語動詞是壹般現在時或將來時,則賓語從句可根據句意的需要而選用任何壹種時態;若主句是壹般過去時 ,賓語從句用表示過去的某種時態。

He says that he wants to see him as soon as possible. 他說他想盡快見到他。

My father said that he was mending his bike. 我父親說他正在修理自行車。

● 如果賓語從句表示客觀真理、科學原理、自然現象、現階段存在的客觀事實、現在經常性或習慣性的動作、諺語、格言等,不論主句用何 種時態,從句壹律用壹般現在時。如:

The teacher told us that light travels much faster than sound. 老師告訴我們光比聲音傳播快。
