Question

【題目】Jackie ________ voluntary work ever since he graduated from college.

A. was devoted to B. devoted to

C. has been devoted to D. had devoted to

Answer 1

【答案】C

【解析】考查時(shí)態(tài)。句意：自從Jackie大學(xué)畢業(yè)后，他一直投身于志愿者工作。根據(jù)句中的since可知主句應(yīng)該用現(xiàn)在完成時(shí)，表示動(dòng)作從過(guò)去持續(xù)到現(xiàn)在。be devoted to表示“專心于，致力于…；獻(xiàn)身…”，故選C。
