江西省吉安县凤凰中学初中英语语法复习 英语中的虚实看“条件”for/without等构成的介词短语作为暗示条件句，相当于if引导的虚拟条件从句。 you didnt let me help. if we_together, you _so tired. a. worked; didnt get b. worked; wouldnt get c. were working; wouldnt get d. had worked; wouldnt have got 答案与解析：d。本题考查条件句中虚拟语气的用法。题干didnt let表明该题说的是过去的事情，与过去事实相反的假设，虚拟语气的从句用“had+过去分词”，主句用“would have+过去分词”的结构。 if you _tomorrow, you _find the new manager working in the office. a.should come; would b.would come; would c.will come; should d.comes; might 答案与解析：a。与将来事实相反时，条件句中的谓语形式有3种：动词的过去式，should+动词原形，were ti +动词原形。 she_much taller, but the cruel stepmother never let her eat enough. a. can growb. can have grown c. could grow d. could have grown 答案与解析：d。从后半句可知，此题省略了条件句“if the stepmother had let her eat enough”，所以用表示过去的虚拟语气。 if he_his legs in the last training, he_the coming world cup, which he has been longing to compete in. a.hadnt hurt; would join in b.hadnt hurt; would have taken part in c.didnt hurt; would go in for d.didnt hurt; would have taken part in 答案与解析：a。从句说的是过去，主句说的是将来，所以要用混合时间条件句。从句按照过去的假设用“had+过去分词”，主句按照将来的假设用“would+动词原形”。 i was away the other day. otherwise i_with him about it. a. had arguedb. would have argued c. would argue d. argue 答案与解析：b。本题前一句是真实情况，后面是假设，其中otherwise含有if i had not been away the other day之意，隐含虚拟语气条件句，表示与过去事实相反，所以选择b项。在连词otherwise, or, but, but that, though. once等引导从句时，主句经常使用虚拟语气。 _him not to do so, he wouldnt have made such a serious mistake. a. did i persuade b. if i persuaded c. if i should persuade d. had i persuaded 答案与解析：d。本题考查虚拟条件从句中省略连词if的情况。根据主句wouldnt have made可知从句该用“had+过去分词”。在if引导的虚拟条件句中，当从句谓语动词含有助动词had/should/were时,可将if省略，而将had/should/were置于句首，采用倒装语序，句意不变。本题答案had i persuaded=if i had persuaded。 yesterday, april walked away from the argument with anger. or else she _something she would regret later. a. had saidb. said c. might say d. might have said 答案与解析：d。此题考查含蓄条件句中情态动词在虚拟语气句型中的用法。从题中walked away可知是过去发生的事情，根据虚拟语气的结构可以推知如果不走开的话，可能会说些以后要后悔的话。had said意为“已经说了”，所以不能选。 well, im sorry to hear that. but such misunder standing _ . a.will have been avoided b.can be avoided c.have had avoided d.could have been avoided 答案与解析：d。此题属于无词语暗示条件句。根据前一句well, im sorry to hear that.可以推断误会已经产生，根据but可以判断句中隐含了一个类似于if we had explained clearly beforehand条件句，所以选择d项。 10._more attention, the teenagers wouldnt have begun to steal. a. to giveb. given c. having given d. give 答案与解析：b。此题通过分词短语表达条件，to do表示目的，having given是完成时的主动状态下分词形式，give动词原形引导句子通常是祈使句，都不符题意。此处given表示被动且虚拟，相当于if they had given more attention，假如给予更多的关心，这些孩子不会去偷窃的。 11. if the boy_to leave school,_ he _a college student now. a. wasnt forced; will be b. hadnt been forced; would have been c. hadnt been forced; would be d. hasnt been forced; would be 答案与解析：c。虚拟语气在非真实条件句中所假设的是不可能有的条件，或者是与事实
