2016高考二輪復(fù)習(xí)英語(yǔ)學(xué)案專題七 情態(tài)動(dòng)詞和虛擬語(yǔ)氣
11. it is vital that we _____ act out at once to protect the environment.
a. would b. should c. will d. can
【解析】b it is vital/important/strange/necessary/natural…that 從句中，從句運(yùn)用should跟動(dòng)詞原形。
12. john’s pale face suggested that he ______ill, and his parents suggested that he ______a medical examination.
a. be, should have b. was, have c. should be, had d. was, has
【解析】b suggest表示“表明，暗示”時(shí)，賓語(yǔ)從句不用虛擬語(yǔ)氣，而表示“建議”時(shí)，要用should 跟動(dòng)詞原形的虛擬語(yǔ)氣。根據(jù)句意可以得知，答案為b
13. but for the leadership of our party and our government, we __________ these splendid results.
a.have achieved b.shouldn’t have achieved
c.should have achieved d.would achieve
【解析】b but for 相當(dāng)于without，可以用if 非真實(shí)條件句替換。有句意可知時(shí)發(fā)生在過(guò)去，與過(guò)去事實(shí)相反。
14. --where have you been?
--i_______in the heavy traffic. otherwise i______here earlier.
a. got stuck; would have come b. got stuck; was
c. have got stuck; would have come d. had got stuck; would come
【解析】a 由句意得知被交通堵塞困住是發(fā)生在過(guò)去，第一空用一般過(guò)去時(shí)，排除cd，第二空為與過(guò)去事實(shí)相反，故選a
15.he hesitated for a moment before kicking the ball, otherwise he ____ a goal.
a. had scored b. scored c. would score d. would have scored
【解析】d 這是otherwise 引出的含蓄虛擬語(yǔ)氣，再根據(jù)前面的 hesitated 可進(jìn)一步知道這是與過(guò)去事實(shí)相反的虛擬語(yǔ)氣 .
【學(xué)法導(dǎo)航】考生在復(fù)習(xí)情態(tài)動(dòng)詞和虛擬語(yǔ)氣時(shí)要注意如下幾點(diǎn)：
1.掌握情態(tài)動(dòng)詞的基本用法；2.正確辨析相近意義的情態(tài)動(dòng)詞；3.把握常用情態(tài)動(dòng)詞句式；
4.學(xué)生要明確所敘述的內(nèi)容不可能發(fā)生或發(fā)生的可能性很小時(shí)，要用虛擬語(yǔ)氣；
5.把握虛擬語(yǔ)氣的常用句式； 6.正確辨析混合時(shí)間的虛擬語(yǔ)氣，如果條件句中的動(dòng)作和主句的動(dòng)作不是同時(shí)發(fā)生，主句和從句的謂語(yǔ)動(dòng)詞的形式應(yīng)分別根據(jù)各自所表示的時(shí)間加以調(diào)整。
7.注意虛擬語(yǔ)氣中的倒裝句，如果虛擬語(yǔ)氣的條件從句謂語(yǔ)動(dòng)詞中含有were, had, should，有時(shí)可將if省去，而將條件從句的主語(yǔ)置于were, had, should, 之后
8.分清含蓄條件句，有時(shí)為了表達(dá)的需要，在虛擬語(yǔ)氣中不總是出現(xiàn)if引導(dǎo)的條件句，而通過(guò)用其他詞來(lái)代替條件句，常見(jiàn)詞有otherwise, or, but for 和if only等
