四類名詞性從句詳解 所謂名詞性從句,就是指其作用相當(dāng)于名詞的從句,它包括主語(yǔ)從句、表語(yǔ)從句、賓語(yǔ)從句和同位語(yǔ)從句。 一、主語(yǔ)從句 1. 引導(dǎo)詞:主語(yǔ)從句就是在復(fù)合句中用作主語(yǔ)的從句,引導(dǎo)主語(yǔ)從句的引導(dǎo)詞主要有三類:一是that;二是whether;三是那些可以用作疑問(wèn)詞的詞語(yǔ),如what, who, which, when, where, how, why等。如: That we shall be late is certain. 我們要晚了,這是確定無(wú)疑的。 What he says is not important. 他說(shuō)的話并不重要。 How this happened is not clear to anyone. 這件事怎樣發(fā)生的,誰(shuí)也不清楚。 Which side wins makes no difference to him. 哪邊贏他都無(wú)所謂。 Whether it will do us harm remains to be seen. 是否對(duì)我們有害還要看一看。 2. 形式主語(yǔ):有時(shí)為了避免句子顯得“頭重腳輕”,可用it作形式主語(yǔ)放在句首,而把真正的主語(yǔ)放在句末。如: It’s a pity that he didn’t come. 很遺憾他沒(méi)來(lái)。 It’s not yet known what she did. 她做什么還不得而知。 It was uncertain whether he could come or not. 他是否會(huì)來(lái)還不肯定。 這三句句首的it均為形式主語(yǔ),相應(yīng)的真主語(yǔ)分別是that he didn’t come / what she did / whether he could come or not。 二、表語(yǔ)從句 表語(yǔ)從句就是在復(fù)合句中用作表語(yǔ)的從句。一般說(shuō)來(lái),可用于引導(dǎo)主語(yǔ)從句的引導(dǎo)詞也可用于引導(dǎo)表語(yǔ)從句,如that, what, who, which, when, where, how, why, whether等。如: My idea is that we should do it right away. 我的意見是馬上就干。 That is what he meant. 這就是他的意思。 The problem is how we can find him. 問(wèn)題是我們?nèi)绾握业剿?SPAN lang=EN-US> The morning is when I’m busiest. 早上是我最忙的時(shí)候。 That’s where you are wrong. 這就是你不對(duì)的地方。 That’s why he didn’t come. 這就是他沒(méi)有來(lái)的緣故。 另外,表語(yǔ)從句還可以用as if, as though, because等來(lái)引導(dǎo)。如: It is because he is too foolish. 那是因?yàn)樗懒恕?SPAN lang=EN-US> It is not as though we were poor. 又不是我們家里窮。 三、賓語(yǔ)從句 1. 引導(dǎo)詞:賓語(yǔ)從句就是在復(fù)合句中用作賓語(yǔ)的從句。一般說(shuō)來(lái),可用于引導(dǎo)主語(yǔ)從句的引導(dǎo)詞也可用于引導(dǎo)賓語(yǔ)從句,如that, what, who, which, when, where, how, why, whether等。如: We believe that he is honest. 我們相信他是誠(chéng)實(shí)的。 She has got what she wanted. 她要的東西得到了。 I haven’t decided whether I should go. 我還沒(méi)決定我是否會(huì)去。 I asked how he was getting on. 我問(wèn)他情況怎樣。 He asked when the train would get in. 他問(wèn)火車什么時(shí)候進(jìn)站。 He asked me where I was going. 他問(wèn)我到哪兒去。 Please tell me which you like. 告訴我你喜歡哪一個(gè)。 He asked who lived next door. 他問(wèn)誰(shuí)住在隔壁。 She asked why he was silent. 她問(wèn)他為什么一言不發(fā)。
