六级英语听力的一句话：

A lot of time people are not really  aware of the impact they have or the fact that taking them in combination with other medication with other medication might put you at risk for something that you wouldn't otherwise being countering or be at risk for.

这句话中后半句wouldn't这个情态动词后后面为什么加being，怎么去解释？然后at risk for 后面宾语是什么？
