回答：1.B should查词典，关于should有：用于表示可能性或可能发生的事件：If she should fall, then so would I.如果她失败了，那我也会失败布什先生可是一个守时的人，他干什么事都不会迟到。他怎么可能在来参加开幕式这件事上迟到呢？如果用can的话，说的就是“能”了，就好像是在问，布什先生是用什么方式做到“去参加开幕式迟到”的。2.B I will.-回家后给我写信。-我会的。will有“愿意”，“将要”等主动积极的意愿的意思。如果说I should，好像是“我应该的。”而里又没有这样说的。 3.A shan't既然你已经在驾校练了好久了，你要通过路考应该不会有什么困难。shan't(=shall not)表示对将来的推测，而shouldn't(=should not)则是对过去的推测。如果这题想用B, shouldn't，应该这样说：There shouldn't have been any difficulty abuot passing the road test since you have practiced a lot in the driving school.
