He may get his teaching qualifications but I couldn’t imagine _

He may get his teaching qualifications but I couldn’t imagine _____ long term in the current school environment.
A、 him work
B、 him working
C、 he working
D、 him to work
【正确答案】：B
【题目解析】：该题考查的是动名词的用法，imagine后接动名词做宾语，或者接动词不定式做宾语补足语，不定式的通常结构为to be，该题中动词为work，因此选择working做为宾语，him作为逻辑主语，选项B为正确答案。
