should的用法■表示“应该，应当”He should work harder. 他应该更加努力。You should help your mother with the housework. 你应该帮你母亲做家务。Crime should be punished. 犯罪应受惩罚。Should I wear a coat?我要穿大衣吗？■表示“可能，该(=will probably) ”He should arrive soon他可能很快就到了。The train should have already left. 火车大概已经走了。■表示“万一”If it should rain tomorrow, don’t expect me. 万一明天下雨，就不要等我了。■表示“竟然”It’s strange that he should be late. 真奇怪，他竟会迟到。■表示粗暴地拒绝一项建议、要求或指示—What time does the film start? 电影什么时候开始?—How should I know? 我怎么知道?—Ann’s very unhappy. 安非常不高兴。—Why should I care? 这管我什么事?—Could your wife help us in the office tomorrow? 你妻子明天能到办公室来帮帮我们吗?—Why should she? She doesn’t work for you. 她为什么就该去? 她又不是为你们工作的。■should加完成式：should have done表示“本应该做某事，但事实上却没有做”；shouldn’t have done表示“本不该做某事，但事实上却做了”。如：You should have got up earlier. 你本应该早点起的。You shouldn’t have told him about it. 你本不该把这件事告诉他的。■should与ought to的比较(1) 除表示“万一”“竟然”等只能用should外，表示“应该，应当”“可能”等，两者可互换，只是ought to的语气稍重。如：You ought to/should work harder than that. 你应当更努力地工作She ought to/should finish it by next week. 下星期她可能完成了。You ought to/should have told him about it earlier. 你本应该早点把这件事告诉他的。You oughtn’t to/shouldn’t have wasted time like that. 你本不该像那样浪费时间的。(2) should 强调主观看法，而 ought to 强调客观要求。如：We ought to go and see my mother in hospital tomorrow, but I don’t think we will. 我们按理应当在明天去看看住院的母亲的，但我主认为我们不会去。(3) 在公告、须知或条例中，出于礼貌，常用should。如：You shouldn’t run alongside the swimming pool. 不准在游泳池边奔跑。(4) 在虚拟语气中只能用should。如：He suggested that I should go there. 他建议我去那里。(5) 注意ought to的否定式与疑问式。如：You ought not to do it. 你不应该做此事。—Ought he to start now? 他现在该动身了吗？—Yes, he ought (to) . 是的，该动身了。They ought to go now, oughtn’t they?他们现在该走了，对吗？
