2010高考英语冲刺：单项选择

　　在时态语态试题中，要求考生注意以下三点：一）在语境中灵活运用时态，切不可以仅根据题干中的时间状语盲目选择时态。二）注意一些特殊句式中时态的固定用法。如"主将从现" 、"祈使句+and/or+将来时单句" 、"make sure that-clause"等 。三）注意英语与汉语的差异，要有使用被动语态的意识。另外要掌握被动语态在各种时态中的构成形式。 如下面一题：

　　He ____ football regularly for many years when he was young.

　　A. was playing B. played C. has played D. had played

　　在主句中出现了时间状语for many years，但是从句说了在他年轻的时候，所以这里踢球几年指的是过去的动作。was playing指过去进行，has played与现在有关，但题干中仅仅说当他年轻的时候与现在无关。had done强调过去的过去。所以选B

　　非谓语动词考点一般只要求考生在不定式，动名词，分词的一般式中做出选择，即在to do, doing， done中做出选择。有时试题的考点要求考生选择非谓语动词的被动式或完成式，但很少考查被动完成式。吴老师告诉考生选择的依据有两点：一是固定搭配，二是在句中的作用。看下面两个例子：

　　The teacher doesn't permit _____in class.

　　A. smoke B. smoking C. to smoke D. smoked

　　这题考查的就是固定搭配，permit doing. permit sb. to do..

　　The young man has the habit of smoking but ______ tea or coffee.

　　A. not drink B. not to drink C. not drinking D. not to drinking

　　这个小伙儿有吸烟的习惯没有喝茶或咖啡的习惯。吸烟和喝茶或咖啡都是作为of的宾语，由连词but唉连词，所以形式一致，用drinking, 非谓语动词的否定在非谓语动词前加not. 故选B.

　　这里总结出了三个情态动词的考点, 那就是：一）常用情态动词用法和意义的辨析。如：must do 与have to do, can do 与be able to do, used to do与would do的区别。二）情态动词后接do, be doing, have done的不同含义。三）情态动词在省略情况下的形式。

　　The room is in a terrible mess; it _____cleaned.

　　A. can't have been B. shouldn't have been C. mustn't have been D. wouldn't have been

　　房间乱的不得了，它一定没被打扫。can't have done对过去情况否定推测，mustn't不能表示推测，故也不会有mustn't have done 这样的搭配。
