1、2011-2012人教版新目標(biāo)英語高二上模塊六unit 1：學(xué)案（虛擬語氣用法詳解） 選修 6 unit 1 art語法課 虛擬語氣用法詳解 1. 條件句中虛擬語氣的形式從句中提出一種與客觀現(xiàn)實不相符或根本不可能存在的條件，主句會產(chǎn)生的一種不可能獲得的結(jié)果。條件句中的虛擬語氣根據(jù)不同的時間有三種不同的形式。時間 從句謂語形式 主句謂語形式將來動詞過去式(be用were)should + 動詞原形were to + 動詞原形would / should / might / could + 動詞原形現(xiàn)在動詞過去式(be 用 were)would / should / might / could +

2、 動詞原形過去had +動詞過去分詞would / should / might / could have + 動詞過去分詞2. 條件中的虛擬語氣的舉例(1) 將來時的條件句中的虛擬語氣。如：if he should go to qing hua university, he would make full use of his time. 如果他要上清華大學(xué)的話，他就會充分利用他的時間了。if he were to come here, he would tell us about it. 如果他要來的話，他會通知我們一聲。(2) 現(xiàn)在時的條件句中的虛擬語氣。如：if he were fre

3、e, he would help us. 要是他有空的話，他會幫助我們的。if he studied at this school, he would know you well. 如果他在這所學(xué)校學(xué)習(xí)的話，它會對你很熟悉。(3) 過去時的條件句中的虛擬語氣。如：if i had seen the film, i would have told you about it. 我如果看過這場電影，我會把電影內(nèi)容告訴你了。if i had got there earlier, i would have met mr. li. 如果我早點到那兒，我就會會到了李先生。3. 運用條件句中的虛擬語氣時，須注

4、意的幾個問題(1) 當(dāng)從句的主語為第三人稱單數(shù)時，謂語動詞若是系動詞be時，可用was代替were。但在倒裝虛擬結(jié)構(gòu)及if i were you, as it were中，只能用were。如：were i ten years younger, i would study abroad. 要是我還年輕十歲的話，我會去國外學(xué)習(xí)。if i were you, i would try my best to grasp the chance.我要是你的話，要盡力抓住這次機會。(2) 混合虛擬語氣/錯綜時間條件句有時，虛擬條件句中，主、從句的動作若不是同時發(fā)生時，須區(qū)別對待。從句的動作與過去事實相反，而主

5、句的動作與現(xiàn)在或現(xiàn)在正在發(fā)生的事實不符。如：if i had worked hard at school, i would be an engineer, too. 如果我在學(xué)校學(xué)習(xí)刻苦的話，我現(xiàn)在也會使工程師了if they had informed us, we would not come here now. 如果他們通知過我們的話，我們現(xiàn)在就不會來這里了。從句的動作與現(xiàn)在事實相反，而主句的動作與過去事實不符。如：if he were free today, we would have sent him to beijing. 如果他今天有空的話，我們會已經(jīng)派他去北京了 。if he k

6、new her, he would have greeted her. 要是他認(rèn)識她的話，他肯定會去問候她了。從句的動作與過去發(fā)生的情況相反，而主句的動作與現(xiàn)在正在發(fā)生的情況相反。如：if it had not been raining too much, the crops would be growing much better. 如果天不下太多的雨的話，莊家會長得更好。if he had been working hard, he would be working in the office now. 要是他工作一直努力的話，他現(xiàn)在已進了辦公室了?；旌咸摂M語氣還有一種情況就是事實和虛擬假

7、設(shè)的混合句，這樣的句子不僅僅是時間的不同，而重要是事實和假設(shè)的混合。 i would have gone to visit him in the hospital had it been at all possible, but i was fully occupied the whole of last week. 該句前半部分是假設(shè)虛擬，而后半部分是事實的陳述。 your math instructor would have been happy to give you a make-up examination had you gone and explained that your p

8、arents were ill at the time. 該句前半句用的是假設(shè)虛擬，后半句主句也用的是假設(shè)虛擬（如果你去并且解釋的話），但是后半句的從句用的是事實語氣，因為“父母病了”是客觀事實，故不需要用虛擬形式had been。 (3) 當(dāng)虛擬條件句的謂語動詞含有were, should, had時，if可省略，而將were, should, had等詞置于句首。如：should he agree to go there, we would send him there. 要是他答應(yīng)去的話，我們就派他去。were she here, she would agree with us. 如果她

9、在這兒的話，她會同意我們的。had he learnt about computers, we would have hired him to work here.如果她懂一些電腦知識的話，我們會已經(jīng)聘用他來這里工作了。(4) 有時，句子沒有直接給出假設(shè)情況的條件，而須通過上下文或其他方式來判斷。如：i would have come to see you, but i was too busy. 我本該來看你了，然而我太忙了。but for his help, we would be working now. 要不是他的幫助，我們還會在工作呢。without your instruction

10、, i would not have made such great progress. 要是沒有你的指導(dǎo)，我不會取得如此大的進步。(5) 有時，虛擬條件句中，主、從句可以省略其中的一個，來表示說話人的一種強烈的感情。省略從句he would have finished it. 他本該完成了。you could have passed this exam. 你應(yīng)該會通過這次考試了。省略主句if i were at home now. 要是我現(xiàn)在在家里該多好啊。if only i had got it. 要是我得到它了該多好啊。2 wish 所接從句的虛擬語氣 對現(xiàn)在虛擬 : wish + (t

11、hat)+did(were) 對過去虛擬 : wish + (that)+had done 對將來虛擬 : wish + would/could/might+do3 would rather 從句的虛擬語氣 對現(xiàn)在/將來虛擬：i would rather sb. did sth. 對過去虛擬：i would rather sb. +had done4 一個堅持insist; 兩個命令order, command ; 三條建議suggest , advise, propose; 六項要求demand, request, require, ask; urge, desire + (that) sb

12、.
