If you ______ in such a hurry you ______ sugar into the sauce instead of salt.

A、 were not, would not put
B、 were, would put
C、 had been, would have put
D、 had not been, would not have put

【正确答案】 D

【答案解析】解析：题干中把糖放到酱汁里这个动作已经发生，因此本句是对过去情况的假设。if条件状语从句应使用had done，主句使用would／should／could have done。选项C和D在语法上都对，不过C用了肯定，表示“如果你匆忙，你会把糖当成盐放到酱汁里”，意思上不合逻辑，故D项正确。
