1.If the new safety system ________ to use,the accident would never have happened.

(2017·北京,34)

A.had been put B.were put C.should be put D.would be put 答案 A

解析 句意为:要是新的安全系统被投入使用了的话,这起事故就不会发生了。此处表示与过去事实相反的情况,所以从句谓语用过去完成时,选A项。 2.—Do you have Betty’s phone number?

—Yes.Otherwise,I ________ able to reach her yesterday.(2017·天津,15) A.hadn’t been C.weren’t 答案 B

解析 句意为:——你有贝蒂的电话号码吗?——有。不然我昨天就联系不上她了。由空前的otherwise及句意可知应用虚拟语气,此处表示与过去事实相反的情况,谓语动词用would have done,故选B项。

3.________ not for the support of the teachers,the student could not overcome her difficulty.

(2017·江苏,22)

A.It were C.It was 答案 B

解析 句意为:如果没有老师们的支持,这名学生不可能战胜困难。此处表示与现在事实相反的假设,从句谓语用were;在非真实条件句中,如果有should,had或were时,可以省略if,而把should,had或were提至主语前,形成部分倒装,故选B项。

B.Were it D.Was it

B.wouldn’t have been D.wouldn’t be

4.Without his wartime experiences,Hemingway ________ his famous novel A Farewell

to Arms.

(2015·重庆,7)

A.didn’t write C.wouldn’t write 答案 D

解析 句意为:要是没有战争时的经历,海明威就不会写出他的著名小说《永别了,武器》。该句使用了含有without的含蓄虚拟语气,由语境知,这里是对过去情况的假设,因此主句谓语用“would/could/should/might+have done”,故D项正确。

5.It is lucky we booked a room,or we ________ nowhere to stay now.(2015·安徽,32) A.had C.would have 答案 C

解析 句意为:很幸运我们订了一个房间,否则我们现在将无处可住。or引导含蓄虚拟条件句,根据“now”可知,是对现在的情况进行虚拟,因此用“would+动词原形”,故选C。 6.Ellen is a fantastic dancer.I wish I ________ as well as her.(2015·陕西,23) A.dance C.had danced 答案 D

解析 句意为:埃伦是一位了不起的舞蹈家。要是我能跳得像她一样好那该有多好啊!I wish后接从句,从句用虚拟语气。叙述与现在事实相反的情况时,谓语动词用过去式(be用were);叙述与将来事实相反的情况时,谓语动词用could/should/would/might do;叙述与过去事实相反的情况时,谓语动词用had done。由语境可知,此处叙述的是与现在事实相反的情况,故谓语动词用过去式,选D项。

7.We would rather our daughter ________ at home with us,but it is her choice,and she is not a child any longer.(2014·陕西,23) A.would stay C.stayed 答案 C

解析 would rather后跟宾语从句时,从句用虚拟语气,从句用虚拟语气,即从句谓语动词用过去式表示与现在或将来事实相反;用“had+过去分词”表示与过去事实相反。根据后一句中的is可知,此处表示与现在或将来事实相反,故此处动词应用过去式,故选C项。 8.It was John who broke the window.Why are you talking to me as if I ________ it?

B.has stayed D.stay B.will dance D.danced B.had had D.would have had B.hadn’t written D.wouldn’t have written
