虛擬語氣練習(xí)題(附答案)bd

1、精選文庫高中英語虛擬語氣練習(xí)題【重點(diǎn)歸納】一、虛擬條件句的類別虛擬條件句可分為三類：一類是敘述與現(xiàn)在事實(shí)相反的情況；一類是敘述與過去事實(shí)相反的情況；另一類是敘述與將來事實(shí)相反的情況。其主句和從句的謂語動(dòng)詞構(gòu)成如下：1. 與現(xiàn)在事實(shí)相反條件從旬用過去時(shí)(be動(dòng)詞的過去式一律用 were),主句用would (should/ might / could) +動(dòng)詞原形”。如：If I were you, I would accept the invitation to the party.如果我是你的話，我將接受去舞會(huì)的邀請(qǐng)。If I knew her well, I would tell you

2、about her.如果我很了解她的話，我將告訴你關(guān)于她的事情。2. 與過去事實(shí)相反條件從句用過去完成時(shí)，主句用“would /should/ might / could + have +過去分詞”, 如：If you had been there last night, nothing would have happened.如果你昨天晚上在那兒的話，就沒有什么事情發(fā)生了。If I had got up earlier, I would have caught the first bus.如果我起得更早一些的話，就趕上頭班車了。3與將來事實(shí)相反條件從句用過去時(shí)或者“ were to + 動(dòng)詞

3、原形”或者 “ should+ 動(dòng)詞原形”， 主句用 “ would ( should/ might/ could) +動(dòng)詞原形”, 如：If it were Saturday tomorrow, we wouldn t have an exam.如果明天是周六的話，我們就不考試了。If you were to visit the school tomorrow, you would see Professor Smith.如果你明天去參觀學(xué)校的話，你就會(huì)看到史密斯教授。If it should rain tomorrow, the sports meet would be put off u

4、ntil next Friday.如果明天下雨的話，運(yùn)動(dòng)會(huì)將被推遲到下周五舉行。【特別提示】在虛擬條件句中，謂語動(dòng)詞按照“后退一步法”使用，即：與現(xiàn)在事實(shí)相反，從句中用一般過去時(shí)；與過去事實(shí)相反，從句中用過去完成時(shí)；與將來事實(shí)相反，從句中用過去將來時(shí)。二、虛擬條件句中的省略與倒裝如果if虛擬條件句中有were, had,或者should等詞時(shí)，可以省略if,把這些詞放在主語前，形成倒裝 句。如：If I should meet her (Should I meet her), I would tell her.如果我遇見她的話，我就告訴她。If I were in your position

5、(Were I in your position), I would do it better.如果我在你的位置上，我會(huì)做得更好。If they had made preparations (Had they made preparations), they would have succeeded.如果他們做了準(zhǔn)備的話，他們就已經(jīng)成功了?！局攸c(diǎn)歸納】1 . 錯(cuò)綜時(shí)間條件句：有時(shí)在非真實(shí)條件句中，主句謂語動(dòng)詞所表示的動(dòng)作和條件從句中謂語動(dòng)詞所表示的動(dòng)作并不同時(shí)發(fā)生，這時(shí)主句和從句的謂語動(dòng)詞要根據(jù)各自所指的不同時(shí)間選用適當(dāng)?shù)奶摂M語氣形式。如：Had I taken my umbrella wit

6、h me when I came out this morning, I should not be wet now.如果我今天早上出來的時(shí)候帶著傘的話，現(xiàn)在就不會(huì)淋濕了。（從句說的是過去的事情，而主句說的是現(xiàn)在的事情）If you had followed the doctor ' s advice, you would be all right now.如果你（那時(shí)）聽從我的建議的話，現(xiàn)在就不會(huì)有事了。（從句說的是過去的事情，而主句說的是現(xiàn)在的事情）If I hadn ' t finished my composition by now, I would be workin

7、g on it tomorrow.如果到現(xiàn)在為止我還沒有完成作文的話，我明天還要接著寫。（從句說的是現(xiàn)在的事情，而主句說的是將來的事情）2 .含蓄虛擬條件句：有時(shí)一個(gè)假設(shè)的情況并不用條件從句表示，而用其它方式來表示，這樣的句子叫含蓄條件句。主要有以下幾種情況。1）用with, without ,but for等介詞短語來替代條件從句，它們都可以轉(zhuǎn)換成由if引導(dǎo)的虛擬條件句。如：We might have died without your help. =We might have died if you hadn' t helped us.如果（那時(shí)）沒有你們的幫助，我們可能已經(jīng)死了。

8、Without the sun, nothing would grow. = If there was no the sun, nothing would grow.沒有太陽，萬物都不能生長。2）用 or, otherwise, but that, suppose/ supposing （that）, provided / providing （that待引導(dǎo)的虛擬語氣。如：You didn ' t come yesterday, or you would have seen him.你昨天沒有來，否則的話，你就已經(jīng)看到他了。I was very busy last week, oth

9、erwise I would have come to see you.我上周很忙，否則的話，我就來看你了。Supposing I was still a little child, I would study hard from now on.假如我還是一個(gè)小孩子的話，我將從現(xiàn)在開始努力學(xué)習(xí)。3）通過上下文來表示虛擬：這種情況下，需要加以分析。I would have given you more money, but I was so poor then.我（那時(shí)如果有錢的話）就可以給你更多的錢了，但是我當(dāng)時(shí)太窮了。I would have called you, but I forgot

10、 your telephone number.我本來可以給你打電話，但是我（那時(shí)）忘了你的電話號(hào)碼。Having known the fact in time, we couldn' t have said that. = If we had known the fact in time, we coukhave said that.如果我們（那時(shí)）及時(shí)知道事實(shí)的話，就不會(huì)說那件事了。Any man in his position would have done that.處于他那個(gè)位置的任何人都會(huì)那樣做的。4）由should + 動(dòng)詞原形或者should/could/might ha

11、ve + 過去分詞構(gòu)成的虛擬語氣。種情況下，虛擬條件句經(jīng)常省略，而只剩下主句結(jié)構(gòu)，如：I should have told you that, but I was afraid that you couldn' t accept the fact.我本應(yīng)該告訴你那件事，但我擔(dān)心你不能接受這個(gè)事實(shí)。Tom, you are so lazy! This work should have been finished hours ago.湯姆，你太懶了！這個(gè)工作本應(yīng)該幾個(gè)小時(shí)之前完成。3 .在if it were/had been not for句型中的虛擬語氣If it were not f

12、or，表示對(duì)現(xiàn)在事實(shí)的假設(shè)；If it had not been for，表示對(duì)過去事實(shí)的假設(shè)。If it were not for the Internet, everything would be very difficult.要不是互聯(lián)網(wǎng)，一切都會(huì)變得很難。Had it not been for your overcoat, I would have died.要不是你那件大衣，我就被凍死了。【經(jīng)典例題】1.
