She begged her aunt not to tell her parents about her behavior and promised she____by the time of their arrival.

a would be improved b will have improved

c would have improved d will be improved

说明原因

个人觉得是C
by the time of their arrival为一段时间
用完成时表示结果
再来improve这个动作应该是she自己发出
用被动欠妥……

选A。这个句子用的是一般过去时，所以BD答案去掉。

凭语感 选A

c
