2019年mpa考试英语真题——动词的时态45

{01}Miss Li ______ as a secretary for five years in the company, and now she is general manager of it.
A.serves
B.served
C.had served
D.has served
解析：考察时态。从and now she is general manager 可知Miss Li 已经不是秘书了，有就是他曾经担任过五年的秘书职务，因此应该用一般过去时态。
本题选B。
{02}She will tell us why she feels so strongly that each of us has a role ________ in making the earth a better place to live．
A.to have played
B.to play
C.to be played
D.to be playing
解析：本题主要考查了动词不定式的时态与语态。从句意看，整个动作发生在将来，to play作a role的定语，其间存在着逻辑上的动宾关系，又与句中each of us存在着逻辑上的主谓关系，故动词不定式用主动形式表示被动意义，首先排除C项；动词不定式to play意指将来的动作，to have played意指已经完成的动作，to be playing则强调动词不定式动作正在发生。
本题选B。
{03}When I said some students were so lazy that they couldn’t hand in their exercise-books, I ________ to you．
A.didn’t refer
B.hasn’t referred
C.wasn’t referring
D.don’t refer
解析：
本题选C。
