题目内容
5.If Mr.Dewey _____ present,he would have offered any possible assistance to the people there.( )A. | were | B. | had been | C. | should be | D. | was |
分析 句意:如果Mr.Dewey在场的话,他就会向那里的人提供可能性的救助.
解答 答案:B.根据从句的结构would have offered可知本题考查的是与过去事实相反的情况,而且主、从句时间一致,不存在混合的情况.与过去事实相反的虚拟语气,条件状语从句要使用"过去完成时had done",主句要使用"would/could/might/should+have done",故B选项正确.
点评 本题考查虚拟语气.要注意语境,记牢if虚拟句中主、从句对应的结构时,套用格式.
