问题描述:

________the project in time , the staff were working at weenkends.
A. CompetingB. Having completed C. To have completedD. To complete
【答案】D
C为啥不对?
有“不定式做目的状语,和主句时态没有关系”这一说法吗?

肯定不能用to have completed 这个不定式的完成式,因为这一形式表示不定式的动作先于谓语动词(这句是:were working) 发生.显然不对这句指的是“员工们在周末工作,为的就是及时完成这个工程”,指的是谓语动词所表动...
