should属情态动词,后接动词原形,没有人称和数的变化。 should的否定形式为should not,缩写形式为shouldn’t。 should有以下几种常见用法:
◆用来向别人提出建议或劝告,意为“应该”。例如:
——Tom, I have a toothache. 汤姆,我牙痛。
——You should see a dentist. 你应当去看牙医。
——I’m not feeling well these days. I have a bad cough. 近来我身体不适,老是咳嗽。
——You shouldn’t smoke so much, I think. 我认为你不该抽这么多烟。
◆用来表示要求、命令。例如:
You should listen to the teacher carefully in class. 在课堂上你应该认真听老师讲课。
注意:此时should与had better, must意义相近。从had better(最好)到should(应该),再到must(必须),语气逐渐加强。试比较:
You’d better go now. 你最好现在就走。
You should go now. 你应该现在就走。
You must go now. 你必须现在就走。
◆用来表示一种预测。例如:
They should be there by now. 他们现在可能到那儿了。
◆有时也用来表示说话人的感情,如:惊讶、愤怒、失望等。例如:
Why should I go?干嘛要我去?(表达不满)
