I ___you have bought a new car.

题目

I ___you have bought a new car.
A.heard B.hear
为什么选B项不选A项?请详解
书上有例句:I heard that he was ill.
I heare him say so
正听见时是:I can hear someone knocking

答案

如果选A,have就要变成had.因为一个句子的时态应该是一致的,完成时表示的是这个动作发生前已经完成了的动作,如果按照这个先后顺序,就是买车在前,听说在后.所以,买车用的是现在完成时,听说就要用现在时,而不是颠倒顺序的过去时.
