C. couldn’t D. needn’t1. should在肯定句中可用来讨论义务和职责或提出建议,意为“应该”。如:
情态动词should的用法You should pay more attention to spelling.2. should后面跟不带to的动词不定式。否定式为should not,其缩略形式是shouldn’t,意为“不应该”。如:
You should not / shouldn’t play football in the street.3. should 用于疑问句,表示征求意见或请求指示。如:— Should I call the police?
— Yes, you should. / No, you shouldn’t.4. should 还可以表示更正别人的说法。— The total price of these books is
230.5 yuan.

Check it again. 注意:should和ought to均可用来谈论义务和职责或提出建议。
两者可以互换使用,不过should常用得多。如:
You should / ought to take your mother’s advice.1. must的意思与should和ought to类似,但语气更强或更肯定,表示“必须”之意,常含有命令的性质;should和ought to的语气则相对缓和些。如:should, ought to & mustYou must give up drinking. 你必须戒酒。
(说话者可能是医生,强调命令执行的必须性)
You really should / ought to give up drinking.
你真的应该戒酒。(可能是来自亲友的劝告。)2. should可以替代must使指示听起来更客气些。如:You should send the letter by 30 June.
你应该在六月三十日之前寄出这封信。3. should和ought to可以用来预测,表示预期会发生什么事情。must往往不这样用。如:明天天气会好的。
