1、高一英語暑假專題高一英語暑假專題虛擬語氣虛擬語氣冀教版冀教版【本講教育信息本講教育信息】一. 教學(xué)內(nèi)容：暑假專題虛擬語氣1虛擬語氣用來表示說話人的主觀愿望或假想，所說的是一個(gè)條件，不一定是事實(shí)，或與事實(shí)相反。虛擬語氣在條件句中應(yīng)用比擬多。2條件句可分為兩類，一類為真實(shí)條件句，一類為非真實(shí)條件句。非真實(shí)條件句表示的是假設(shè)的或?qū)嶋H可能性不大的情況，故采用虛擬語氣。1. 真實(shí)條件句用于陳述語氣，假設(shè)的情況有可能發(fā)生。各種結(jié)構(gòu)參見下表：條件從句主句shall/will + 動(dòng)詞原形祈使句句型一般現(xiàn)在時(shí)情態(tài)動(dòng)詞一般現(xiàn)在時(shí) 例如：if he comes, he will bring his violin.

2、 如果他來，會(huì)帶小提琴來的。典型例題the volleyball match will be put off if it _.a. will rain b. rains c. rained d. is rained答案 b。真實(shí)條件句主句為將來時(shí)，從句用一般現(xiàn)在時(shí)。注意：1在真實(shí)條件句中，主句不能用 be going to 表示將來，該用 shall, will.錯(cuò) if you leave now, you are never going to regret it.對(duì) if you leave now, you will never regret it.2表示真理時(shí)，主句謂語動(dòng)詞不用 sha

3、ll will +動(dòng)詞原形，而直接用一般現(xiàn)在時(shí)的動(dòng)詞形式。2. 非真實(shí)條件句 1虛擬語氣可以表示過去，現(xiàn)在和將來的情況，時(shí)態(tài)的根本特點(diǎn)是時(shí)態(tài)往后推移。a. 與現(xiàn)在事實(shí)相反的假設(shè)條件從句主句一般過去時(shí)be 用wereshouldwould等 +動(dòng)詞原形例如：if they were here, they would help you. 如果他們?cè)谶@兒，會(huì)幫助你的。含義：they are not here, they cant help you.b. 與過去事實(shí)相反的假設(shè)條件從句主句過去完成時(shí)shouldwould等+ have+ 過去分詞 例如：if he had come yesterday,

4、 i should / would have told him about it.如果他昨天來的話，我會(huì)把這件事告訴他的。 含義：he did not come yesterday, so i did not tell him about it.c. 表示對(duì)將來不大可能發(fā)生的事情的假想條件從句主句一般過去時(shí)should/would 等 + 動(dòng)詞原形were+ 不定式should+ 動(dòng)詞原形 例如：if you succeeded, everything would be all right. 如果你將來成功了，一切都會(huì)好的。 if you should succeed, everything

5、would be all right.if you were to succeed, everything would be all right.含義：you are not likely to succeed, everything will be what it is now.3. 混合條件句 有時(shí)，主句與從句的動(dòng)作發(fā)生在不同的時(shí)間，主句從句謂語動(dòng)詞的虛擬語氣形式因時(shí)間不同而不同，這種條件句叫做混合條件句。例如：if you had asked him yesterday, you would know what to do now. 如果你昨天問過他，今天就知道做什么了。從句與過去事實(shí)相

6、反，主句與現(xiàn)在事實(shí)相反。 if it had rained last night過去, it would be very cold today現(xiàn)在.如果昨晚下過雨，今天就會(huì)很冷了。4. 虛擬條件句的倒裝 虛擬條件句的從句局部含有 were, should 或 had 時(shí), 可省略 if，再把 were, should 或 had 移到從句的句首，實(shí)行倒裝。例如：were they here now, they could help us. =if they were here now, they could help us.他們現(xiàn)在在的話，就會(huì)幫助我們了。had you come earlie

7、r, you would have met him. =if you had come earlier, you would have met him.你來得早一點(diǎn)，就碰到他了。should it rain, the crops would be saved. =were it to rain, the crops would be saved.假設(shè)下雨，莊稼就有救了。注意：在虛擬語氣的從句中，動(dòng)詞“be的過去時(shí)態(tài)一律用“were，不用 was，即在從句中 be 用 were 代替。例如：if i were you, i would go to look for him. 如果我是你，就會(huì)去找

8、他。if he were here, everything would be all right. 如果他在這兒，一切都會(huì)好的。典型例題_ to do the work, i should do it some other day.a. if were i b. i werec. were id. was i 答案 c。在虛擬條件狀語中如果有 were, should, had 這三個(gè)詞，通常將 if 省略，主語提前, 變成 were, should, had +主語的形式。但要注意，在虛擬條件狀語從句中，省略連詞的倒裝形式的句首不能用動(dòng)詞的縮略形式。如我們可說 were i not to d

9、o, 而不能說 werent i to do。5. 特殊的虛擬語氣詞 should 1在主語從句中的應(yīng)用it is demanded / necessary / a pity + that等結(jié)構(gòu)的主語從句，謂語動(dòng)詞用 should 加動(dòng)詞原形，should 可省略。 可用的詞有三類suggested, ordered, required, proposed, demanded, requested, insisted 等important, necessary, natural, imperative, strange 等it isa pity, a shame, no wonder 等tha

11、示、說明、 “堅(jiān)持認(rèn)為時(shí)，賓語從句用陳述語氣。 判斷改錯(cuò)：錯(cuò)you pale face suggests that youshouldbe ill. 對(duì)your pale face suggests that you are ill. 錯(cuò)i insisted that youshouldbe wrong. 對(duì)i insisted that you were wrong.3在表語從句，同位語從句中的應(yīng)用suggestion, proposal, idea, plan, order, advice 等名詞后面的表語從句、同位語從句中要用虛擬語氣，即should+動(dòng)詞原形。例如：my idea is

12、 that weshouldget more people to attend the conference.我的想法是讓更多的人來參加會(huì)議。i make a proposal that weshouldhold a meeting next week.我提了個(gè)建議，下周我們開個(gè)會(huì)。6. wish 的用法 1wish 后面的從句，表示與事實(shí)相反的情況，或表示將來不太可能實(shí)現(xiàn)的愿望。其賓語從句的動(dòng)詞形式為：主句從句從句動(dòng)作先于主句動(dòng)作be 的過去式為 were現(xiàn)在時(shí)過去時(shí)從句動(dòng)作與主句動(dòng)作同時(shí)發(fā)生had + 過去分詞過去時(shí)過去完成時(shí)將來不大可能實(shí)現(xiàn)的愿望將來時(shí)would/could +動(dòng)詞原形例
