情態(tài)動(dòng)詞ought to的用法總結(jié)
一、Ought to表示應(yīng)該。如: 1.You ought to take care of him. 你應(yīng)該照顧他。 2.You ought to scrap the old bike and buy a new one. 你應(yīng)該扔掉這輛舊自行車,買一輛新的。 3.You ought to have a haircut. 你該去剪發(fā)了。 二、表示推測(cè)。注意與must表示推測(cè)時(shí)的區(qū)別: He must be at home by now. (斷定他已到家) He ought to be home by now. (不十分肯定) This is where the oil must be. (比較直率) This is where the oil ought to be. (比較含蓄) 三、“ought to + have + 過(guò)去分詞”表示過(guò)去應(yīng)做某事而實(shí)際未做。如: You ought to have asked him (but you didn't). 這時(shí),ought to和should可以互相換用。 注意:在美國(guó)英語(yǔ)中,ought to用于否定句和疑問(wèn)句時(shí),to可以省略。如: Ought you smoke so much? You oughtn't smoke so much. 四、ought和should的區(qū)別: ought語(yǔ)氣略強(qiáng),should較常用;ought在美國(guó)英語(yǔ)中用的很少,而should卻相當(dāng)常用; ought屬正式用語(yǔ)。由于ought to 沒(méi)有過(guò)去式,所以在直接引語(yǔ)變間接引語(yǔ)的過(guò)程中,就不再變化.例如: 1.She failed one of the exam papers, but we ought to make allowance for the fact that she was ill. 她有一門不及格,但我們必須考慮到她當(dāng)時(shí)有病。 2.Regularity ought to be observed, as regularity is very conducive to health. 生活應(yīng)遵守規(guī)律,因?yàn)橐?guī)律對(duì)健康有益。 3.China ought to make a greater contribution to humanity. 中國(guó)應(yīng)當(dāng)對(duì)于人類有較大的貢獻(xiàn)。 4.He is a very good tennis player; you ought to see him in action. 他是個(gè)很好的網(wǎng)球運(yùn)動(dòng)員,你應(yīng)當(dāng)去看看他打球。 5.I think there's a train at 8.20 but you ought to make certain. 我想8點(diǎn)20分有一班火車,不過(guò)你應(yīng)該打聽(tīng)清楚。 6.I think you ought to go to/to go and see the doctor. 我認(rèn)為你應(yīng)當(dāng)去找醫(yī)生看看病。
