Sally’s score on the exam is the lowest in the class. She______ hard.
选项
A、should have studied
B、must have to study
C、must have studied
D、needn’t have studied
答案
A
解析
实际情况是莎莉成绩最差,那么说明她以前没认真学习。用“should+完成时态”表示过去应该做而没有做到的情况。B.“must have to study”,must不能与have to连用,两者重复。C“must have studied”表示对过去情况的一种推测,与句意相反。D.“needn’t have studied”表示没必要做而实际已经做了,与句意也不符合。
