一、虛擬語(yǔ)氣在條件句中的使用,[注意] (1)用介詞with,without,but for等替代條件句。 But for your advice,I could not have done it so successfully.要是沒(méi)有你的建議,我就不會(huì)那么成功。 The changes could not have taken place without the open door policy.要是沒(méi)有開(kāi)放政策,就沒(méi)有這些變化。,(2)省略if的虛擬條件句。 if引導(dǎo)的虛擬條件句的謂語(yǔ)動(dòng)詞中含有had,should,were時(shí),可將if省略。而將had,should,were置于句首,采用倒裝語(yǔ)序,而句意不變。 Had he worked harder,he would have got through the exams.如果他學(xué)習(xí)刻苦些,他就會(huì)通過(guò)考試了。 Were she younger,she would do it. 如果她再年輕點(diǎn),她會(huì)做這件事的。 Should it rain next week, the farmers would have a good harvest.倘若下周下雨,農(nóng)民就會(huì)有好收成。,二、混合(時(shí)間)錯(cuò)綜型虛擬條件句 通常情況下,在非真實(shí)條件句中主句和從句的謂語(yǔ)動(dòng)詞所指的時(shí)間是一致的,但有時(shí)也可能指不同的時(shí)間,這時(shí)要根據(jù)上下文的意思采用不同的謂語(yǔ)動(dòng)詞形式。即:從句和主句根據(jù)各自謂語(yǔ)動(dòng)作發(fā)生的時(shí)間不同,采用相應(yīng)的謂語(yǔ)動(dòng)詞形式。 1.從句表示過(guò)去,主句表示現(xiàn)在 If they had started the early morning yesterday,they would be here now. 如果他們昨天一大早出發(fā)的話,他們現(xiàn)在該到這里了。,2.從句表示將來(lái),主句表示過(guò)去 If I were not to make a preparation for my experiment this afternoon,I would have gone to see the film with you last night.如果不是準(zhǔn)備今天下午的實(shí)驗(yàn),我昨晚就和你一塊 去看電影了。 3.從句表示過(guò)去,主句表示將來(lái) If we hadn't made adequate preparations,we shouldn't dare to do the experiment next week. 如果我們沒(méi)有做好充分準(zhǔn)備,下周我們就不敢做此實(shí)驗(yàn)。,4.從句表示將來(lái),主句表示現(xiàn)在 If we shouldn't have an exam this afternoon,I would go shopping now.如果今天下午我們不考試,我現(xiàn)在就去購(gòu) 物了。 5.從句表示現(xiàn)在,主句表示過(guò)去 If I were you,I would have gone to her birthday party. 如果我是你,我就去參加她的生日聚會(huì)了。,6.從句表示過(guò)去,主句表示過(guò)去和現(xiàn)在 If you hadn‘t lent me some money,I couldn’t have bought the new house and most likely I would be still living in the dangerous house now.如果你不借給我錢的話,我就不能 買新房子了,而且很可能我現(xiàn)在仍然住在危房里。,三、虛擬語(yǔ)氣在其他從句中的使用 1.wish的賓語(yǔ)從句的虛擬語(yǔ)氣有三種情況: (1)表示現(xiàn)在不能實(shí)現(xiàn)的愿望,從句謂語(yǔ)動(dòng)詞用過(guò)去時(shí); (2)表示過(guò)去不能實(shí)現(xiàn)的愿望,從句謂語(yǔ)動(dòng)詞用過(guò)去完成時(shí); (3)表示將來(lái)不能實(shí)現(xiàn)的愿望,從句謂語(yǔ)動(dòng)詞用 “would/could/might+動(dòng)詞原形”。 How I wish I were you!我多么希望我就是你!
