Question

【題目】The young couple _______ as volunteer teachers for a whole year during their stay in Yunnan.

A. have worked B. had worked

C. worked D. have been working

Answer 1

【答案】C

【解析】

考查時(shí)態(tài)。句意：在云南期間，這對(duì)年輕的夫妻做了一整年的志愿者。根據(jù)句意可知他們是在云南期間做志愿者的，使用一般過去時(shí)描述過去發(fā)生的事情，并沒有延續(xù)到現(xiàn)在，也沒有表現(xiàn)出對(duì)現(xiàn)在的影響，故C項(xiàng)正確。
