come,C,would come D,would have come,【,解析,】,考查虚拟语气。从语意分析，这是非真实条件句中对过去状况的虚拟，主句谓语用,should/would/could/might have done,，条件句用过去完成时态，答案应选,B,项。,【,答案,】,B,6.(2009,年日照二模,),“,If,I_taking,drugs,，,I would be a successful businessman now,，,”,said the dying heroin addict.,A,didn,t start B,haven,t started,C,hadn,t started D,shouldn,t

ticket,，,I_it,.,A,wouldn,t have missed,B,wouldn,t miss,C,didn,t miss,D,hadn,t missed,【,解析,】,考查虚拟语气。从句为过去完成时，所以主句用,would have done,结构。,【,答案,】,A,8.(2009,年南通二模,),Sorry indeed,，,I_to,your birthday party if.,Forget,it.I,know you were out on business.,A,must come B,would come,C,must have come D,would have come,【,解析,】,考查虚拟语气。此处表示对过去的虚拟，,if,后面省略了过去完成时,(,补充完整应该是,if I had not been out on

switch,C,should switch D,must be switched,【,解析,】,考查虚拟语气。在,“,It is,vital/necessary/important/strange/unusual/natural/surprising/suggested/required/ordered,that,从句,”,结构中，,that,从句中的谓语动词用,(,should)do,的形式，而,switch off,与,lights,之间存在动宾关系，所以要用被动语态。,【,答案,】,A,10.(2009,年合肥二模,),Did you make it at last?,Yes.But,for your help,，,it_a,serious loss.,A,would cause B,must have caused,C,would have caused D,may

shut,【,解析,】,该题考查虚拟语气。,wish,后跟从句，从句要用虚拟语气，因为后面是过去时，故此处表示与过去事实相反，要用过去完成时。,【,答案,】,C,12.(2009,年青岛一模,),My uncle suggests,I_abroad,.,I would rather,you_at,home.,A,go,；,stay B,went,；,stayed,C,go,；,stayed D,went,；,stay,【,解析,】,suggest,当,“,建议,”,讲时，从句中要用虚拟语气，结构是,“,should,动词原形,”,，,should,可以省略。,would rather,后面跟从句时，从句中也要用虚拟语气，根据语境此处应用过去时。,【,答案,】,C,13.(2009,年东北三校第二次联考,),Why do you look so upset?,I broke up with my,girlfriend.If,only,I_more,about her.,A,care B,cared,C,had cared D,had been cared,【,解析,】,考查虚拟语气。,If only,表示,“,要是,就好了,”,，后面的句子要用虚拟语气。表示与过去的事实相反的情况时，谓语动词用,had

arrived,【,解析,】,考查虚拟语气。答语的意思是,“,我遇到交通堵塞了，否则我本来可以早一点到的,”,。言外之意是如果不是交通堵塞，就可以早点到达，因此此处是虚拟语气，相当于,“,If I hadn,t got stuck in the traffic jam,，,I would have arrived earlier.,”,。,【,答案,】,D,15,(2009,年南昌二模,),Why didn,t you buy the gold ring?,I_,，,but I didn,t have the money.,A,would have B,bought,C,would like to D,had bought,【,解析,】,考查虚拟语气。上文问的是没有买的理由，下文自然是对过去的事情的原因的陈述，,but I didn,t have the money,给出的是事实，换句话说，如果有钱的话，,“,我,”,就会买。所以选,A,。此处可以变形为：,I would have bought it if I had had the money.,【,答案,】,A,
