Question

【题目】______ the project, they decided to stay there for another week.

A.Not completingB.Not completed

C.Not having completedD.Having not completed

Answer 1

【答案】C

【解析】

考查非谓语动词。句意：由于没有完成这个项目，他们决定在那里再干一周。they与complete之间是逻辑上的主谓关系，表示主动，用现在分词作状语，complete这一动作发生在decided之前，所以用现在分词的完成式作原因状语，否定词not放在最前面，故C项正确。
