题目内容
17.If penicillin had not been available,many peoplewould have died(die)from sickness or even small wounds.分析 如果没有青霉素,很多人会因为疾病或小的伤口而死亡.
解答 答案是would have died.本题考查虚拟条件句中的动词;从句中"如果没有青霉素"是与事实相反的假设;从句中动词是过去完成时,说明这是与过去事实相反的假设,相应的主句的动词用"would/could/should/might+have done"的形式;本题中表示"本会…",所以选择would,故答案是would have died.
点评 本题是要求用所给动词的适当时态填空,解题时要寻找题干中所提供的时态依据,同时关注特殊的时态结构.
