Question

— My colleague felt quite happy because his solution was closer now to ______．
— Congratulations!

A．having adopted

B．be adopted

C．being adopted

D．be adopted

Answer 1

C

考查固定搭配。was closer now to是用的be close to结构，to 是介词，后面要跟动词的ing形式，排除B,D；且主语his solution和动词adopt之间是动宾关系，所以要用doing的被动式，选C。
