题目内容
13.If he___ to the teacher attentively,he ___the answer to the problem now.( )A. | had listened; would have known | B. | listened; would know | ||
C. | listened; would have known | D. | had listened; would know |
分析 如果在过去的一年里他认真听老师讲课了,那么他现在就能够知道这个问题的答案了.
解答 从in the past year 判断前面条件状语从句是对过去进行假设,应该用过去完成时;而后面主句中的now则提示应该是对现在的虚拟,应该用would+动词原形,所以整个句子是混合型的虚拟语气,正确答案为D.
点评 考查混合型虚拟语气.
