学位英语语法高频考点小结(2)

虚拟语气如果所表示的条件根本不可能实现或实现的可能性很小时,称为虚拟条件句。

考试重点:虚拟语气的基本形式和用法;if的省略形式;含蓄条件句;以wish(that)引导的表示“愿望”的宾语从句;would rather 引导的从句;以as if, as though 引导的从句;以suggest, advise, insist 等词后引导的宾语从句;It is necessary(important)that引导的主语从句;It is time (that)…句型中。

一、虚拟语气的基本形式和用法:

虚拟(条件)语气中,主句与从句中谓语动词的形式可分为下面三类:

1、I would ask George to lend us the money if I _____ him.

A. had known

B. have known

C. knew

D. know

(答案:C。与现在的事实相反,从句用过去时)(1995年38题)

2、Do you think there would be less conflict in the world if all people _____ the same language?

A. spoke

B. speak

C. had spoken

D. will speak

(答案:A。与现在的事实相反,从句的谓语动词用过去时。)

3、If Bob____ with us, he would have had a good time.

A. would come

B. would have come

C. had come

D. came

(答案为C。与过去的事实相反,从句的谓语动词用过去完成时。)(1995年59题)二、if的省略形式

在虚拟条件句中,如谓语包含were , had, should等词,则可以把这些词放到主语前面,省略if。

1、_____ you were busy, I wouldn't have bothered you with my questions.

A. If I realized

B. Had I realized

C. Did I have realized that

D. As I realized

(答案:B。虚拟条件句有时可以省略if,而将谓语中的过去式were,had,或should等移至主语之前。1996年39题)

2、_____, I should ask them some questions.

A. Should they come to us

B. If they come to us

C. Were they come to us

D. Had they come to us

(答案:A。与将来事实相反。)(1997年30题)

三、含蓄条件句

有时一个假设的情况不用条件从句表示,而用其它方式来表示,这样的句子叫含蓄条件句。常用with,without,but for。

1、Without your help, we _____ so much.

A. didn’t achieve

B. would not have achieved

C. will not achieve

D. don’t achieve

(答案:B。这是一句含蓄条件句,条件暗含在介词短语without your help中,因此要用虚拟语气。)(1996年33题)

2、But for the rain, we _____ a nice holiday.

A. should have

B. would have had

C. would have

D. will have had(答案:B。2003年28题)

四、以wish(that)引导的表示“愿望”的宾语从句

wish后的宾语从句中要用虚拟语气,而在虚拟语气中时态的应用类似在非真实条件中从句时态的应用。表示现在或将来的愿望用:主语+wish +从句(主语+过去时);表示一个过去没有实现的愿望用:主语+wish +从句(主语+过去完成时);

1、Peter wishes that he _____ law instead of literature when he was in college.

A. could study

B. studied

C. had studied

D. would study(答案:C)(2000年53题)

2、I didn’t go to the party, but I do wish I _____ there.

A. were

B. would be

C. had been

D. will be(答案:C)(2001年53题)

五、would rather+句子(过去时)

1、I’d _____ you didn’t touch that, if you don’t mind.

A. rather

B. better

C. happier

D. further(答为案:A)(1998年45题)

2、I am too busy these days. I would rather all of you _____ next month for a dinner.

A. come

B. would come

C. came

D. have come(答案为C)(2002年46题)

六、以as if,as though引导的从句

在as if,as though引导的从句中,如果谈论的是不可能或不真实的情况时,它们所引用的状语从句要用虚拟语气,动词形式和wish 后面的从中动词形式变化相同。

1、He talks as if he _____ everything in the world.

A. knows

B. knew

C. had known

D. would have known

(答案:B。as if(though)从句中非真实性情况用虚拟语气。本句表示说话人对现在的情况有所怀疑,所以用过去时。)

2、You are talking as if you had seen them

你谈的那么起劲,好像你真的见过似的。(表示想象中的过去的动作)

七、以suggest,advise,insist等词后引导的宾语从句中,从句的谓语动词要用should+动词原形,should可以省略。

类似的动词有:propose,insist,suggest,order,demand,require,request等。

A. had
