Question

"Mr．White _________ at 8：30 for the meeting, but he didn’t show up．"

A. should have arrived B. should arrive C. should have had arrived D. should be arriving

Answer 1

答案A
题意是“瓦特先生应该八点半到会，但是，他没到”。这是一个带有含蓄条件句的虚拟语气。C项错，因为无此形式；should+have
done表示过去应该干，但是没有干；should
be
doing表示现在应该正干某事。A项符合本题要求。
