2014全国高考汇编之虚拟语气+情态动词
一（2014安徽卷）30．People are recycling many things which they away in the past.
A. had thrown B. will be throwing
C. were throwing D. would have thrown
【考点】考察情态动词用法
【答案】D
【解析】句义：人们作者回收利用他们过去常常会扔掉的东西。Would have done过去常常做某事；是对过去发生的事情的推测。如果不适应情态动词，可以使用一般过去时threw。故D正确。
【举一反三】I ______ sooner but I didn’t know that they were waiting for me.
A. had come B. was coming C. would come D. would have come
【答案】D
【考点】考查虚拟语气的用法。
【解析】句意为“我本来可以早点来，但我真不知道他们在等我。”but I didn’t know表示了过去时间，因此前句是对过去的虚拟，用主语+should / would / could / might + have done表达，故选D。
二（2014北京卷）27. ________ I have a word with you? It won’t take long.
A. Can B. Must
C. Shall D. Should
【考点】考察情态动词词义辨析
【答案】A
