第11题：
( )us the information，we would have been ambushed.A.Had he not given
B.If he did not give
C.Should he not give
D.Were he not to give答案：A解析：考查虚拟语气。根据后半句would have been可知，是与过去事实相反，所以if条件句中的谓语动词用had+done的形式，因此A项正确。当if引导的虚拟条件从句中含有had，were 或should时，如省略if，则要将had，were或should提前。此处是省略了if并将had提前，还原为if he had not given us the information。故本题选A。句意：如果不是他给了我们消息，我们就会遭到伏击。 -
第12题：
单选题He _____ unwisely, but he was at least trying to do something helpful.Amay have acted
Bmust have acted
Cshould not act
Dwould not act
正确答案： C解析：
句意：尽管他的行为不够明智，但至少他在努力做一些有益的事情。may用于从句中表示让步，不管，不论；尽管。must have acted用在此处语气不正确。由从句可知，事件发生在过去，故C项D项不可选，前后时态搭配不一致。 -

D.could get through答案：C解析：考查虚拟语气。根据前半句可知该句是省略if的虚拟条件句，表示的情况与过去事实相反，所以主句谓语用would／should／could／might+have+过去分词的形式。相当于：If he had worked harder,he would have got through the exams．故选C。 -
第22题：
Not until the game had begun at the sports ground．A.should he have arrived
B.would he have arrived
C.did he arrive
D.had he arrived答案：C解析：【考情点拨】考查not until引导的时间状语从句。
【应试指导】句意：直到比赛开始他才到达运动场。not until引导时间状语从句时主句要部分倒装。从句中的时态为过去完成时，故主句中的时态应为一般过去时，故选C。 -
第23题：
Not until the game had begun( )at the sports ground.A.had he arrived
B.would he have arrived
C.did he arrive
D.should he have arrived答案：C解析：考查倒装句。本题因not until在句首，所以应用倒装语序。因为从句的动作发生在主句的动作之前，所以从句用了过去完成时，主句要用过去时。故本题选C。句意：直到比赛开始，他才到达运动场。 -
