【题目】By the end of 2020, as is clearly stated, poverty relief work ________ across the country.
A.will have accomplishedB.has been accomplished
C.has accomplishedD.will have been accomplished
在线课程【答案】D
【解析】
考查时态。句意：到2020年底，全国扶贫开发工作将基本完成。根据By the end of 2020可知主句的时态为将来完成时，且主语为poverty relief work，因此要用被动语态。故选D项。
