—Will you go shopping now?
—Not until I ____ my experiment.
A．have finished B．will finish C．finished D．had finished
选哪一个？为什么？请详解，谢谢。

选A

意思是知道我完成试验了再去购物。

完成实验的动作要先于购物的。

所以要用现在完成时。

I will not go shopping until I have finished my experiment.

选A．have finished
Not until I have finished my experiment.
是“I won't go shopping until I have finished my experiment.”的缩写。
所以要用将来时。

A
这是一个省略句式。
补充完整应该是I will not go shopping until I have finished my experiment。其实这里填finish更恰当一些。

A 意思是直到我完成试验了再去购物
要用现在完成时（have+动词过去分词）

选A。
