I don't understand why you __ your mind constantly!We haven't been able to decide where to spend our holiday,you know?A.change B.will change C.are changing D.have changed答案选C,

Answer 1

现在进行的其中一个用法就是：表示长期的或重复性的动作,说话时动作未必正在进行.句中的constantly决定了这个地方选C而不能选A. 说简单点. 你吧这种延续性动作理解为他时常在改变主意一直在进行着的一种状态.
题目一共有两句话,分别是以why和where引导的宾语从句.
四个选项的区别只在时态上,分别是：一般现在时、一般将来时、现在进行时和现在完成时.
那么注定选c了 . 希望可以帮助你.
