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。 —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(from www.): 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? |
