怎样判断这是非谓语从句还是祈使句呢

Before you quit your job,____ how your family would feel about your decision.
A. consider B. considering C. to consider D.considered

1 祈使句 也是句子。只要有从句如Before you quit your job，就选祈使句
2. 看句中是否有连词
use your head and you will find the way 有连词 and
using your head , you will find the way

选A，这应该是由before引导的时间状语从句，而主句是含有宾语从句的祈使句。

祈使句，有些命令式的口气

Before you quit your job,____ how your family would feel about your decision. A. consider B. considering C. to consider D.considered 答案是A。 翻译：在你辞职之前，请先考虑下你的家人该作何感想。
