同学们，一定要加把劲努力复习了，以下就是由精品学习网为您提供的2015高三英语同步训练题。

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.
