求助一道语法题，关于时态的！

When he phones her, she tells him to stop calling, but he acted as if he had not understood her.
A. she tells him to stop calling, but he acted as if he had not understood her.
B. she told him to stop calling, but he acted as if he had not understood her.
C. she tells him to stop calling, but he acts as if he did not understood her.
D. she tells him to stop calling, but he acts as if he has not understood her.
E. she tells him to stop calling, but he acted as if he does not understood her.


答案我选择A，如果C里面换成understand是否也可选？

高人出现啊~~

这种妖题只能用排除法。先把CE排除，再排除B，tell一定要用一般现在时的，因为前面是phones。只剩下A和D。
根据时态的一致性，选择D比较好，都是现在时。没有确切的证据表明but后面要用过去时。

C- " has not understood her" emphasis the action after "she tells him to stop calling"

daivx

我也觉得C！
