Question

Miss Li ________ as a biology teacher for fifteen years in our school, and now she is Party secretary of our city.

A. works　　　　　 B. worked　　　 C. had worked　 D. has worked

 

Answer 1

B

 

考查動詞時(shí)態(tài)。句意：李老師曾經(jīng)在我們學(xué)校當(dāng)了15年的生物老師，現(xiàn)在她是我們市的黨委書記。根據(jù)句意過去當(dāng)了15年的生物老師可知用一般過去時(shí)。故選B。
