选择题
If he _______ to the teacher attentively in the past year, he _______the answer to the question now.
A.had listened; would know
B.listened; knew
C.listens; knew
D.has listened ;knows
答案
答案:A
题目分析:考查混合型虚拟语气。句意: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。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A。
