1. It’s nearly seven o’clock. Jack ______ be here at any moment.
A. can B. will C. should D. may
四个选项均可表示推测,但 can 表推测时通常不用于肯定句,所以可首先排除 A。在余下的三个选项中,should 表示的可能性最大,意思是“应该”“理应”,但根据上文中说的“差不多快七点了”可知,说话者认为这个时候 Jack 应该随时会到。如果假定特别的情景,B、C、D都是有可能的,但就一般的常理来说,C是最佳的。
2. Professor Wang, many students want to see you. _____ they waithere or outside?
A. will B. shall C. may D. can
答案为 B,shall 在此用于征求对方意见,可以用第一人称和第三人称。又如:
Shall I turn on the light? 要开灯吗?
Shall we sit here? 咱们坐这儿怎么样?
Shall he send you a check? 要不要他给你寄张支票?
