题目内容
15.If it had been possible,I would have helped him,but I ______ too busy.( )| A. | had been | B. | would be | C. | were | D. | was |
分析 翻译:如果可能的话,我肯定会帮助他的,但是我太忙了.
解答 答案:D.句中If it had been possible,I would have helped him,此句用的是:If+主语+had+动词过去分词,主语+would/should/might/could have+动词过去分词.此句是与过去事实相反的虚拟语气的用法,所以描述的是过去的事情;后半句"但是我很忙"是引导的真实情况,指过去那段时间很忙,应该用一般过去时,I为单数,后应用was.故选D.
点评 本题主语考查的是考查虚拟语气及时态的用法,本题是对过去的虚拟,因此应该用过去时.
