We can use had better to give strong advice in a particular situation. Zhang Xin is calling his cousin Zhang Lei for advice on designing a poster. Read the dialogue and pay attention to the words in bold. Zhang Xin: Lei, I’m going to take part in the poster design competition next week. My teacher said we should pick something related to Chinese culture. Zhang Lei: Cool! There are so many topics to choose from. Remember, you shouldn't put too much information on your poster. Zhang Xin: That's important to know! Can I make a poster about how people travelled in ancient China? Zhang Lei: Hmm ...You'd better not pick such a broad topic. How about the Silk Road? Zhang Xin: Sounds good! Thank you! Zhang Lei: You'd better start early. It can take a long time to make a poster. ·We use should and had better with the base form of a verb. ·The negative form of had better is had better not. Look! should not =shouldn't Ought to is similar in meaning to should. You ought to read more English books. had better='d better had better not='d better not A 情态动词should should意思是“应该；应当”，表示劝告、建议或义务。 1 可用于任何人称，无形式变化，后接动词原形。如： You should complete your homework in time. 你应该按时完成作业。 I think he should respect his parents. 我认为他应该尊重父母。 2 should的否定式：should not，可缩写为shouldn’t。如： You shouldn’t stay up late every night. 你不应该每晚都熬夜。 We shouldn’t make noise in the library. 我们不应在图书馆里喧哗。 3 ought to和should两者的意思大体上相同，很多情况下可以互相转换，但也有一些差别。ought to更多的表示因责任和义务或按道理应该做的事情。should 则侧重表示某件事情适宜于这样做，属于一种良好的建议。如： We should drink about eight cups of water a day. 我们应该一天喝八杯水。 We ought to keep our home clean and tidy. 我们应保持家里干净整洁。 You should do as he says. 你应该按他说的做。（出于良好愿望的建议） You ought to do as he says. 你应当照他说的做。（责成或敦促） B had better用法 had better是固定词组，意思是“最好”，表示劝告、建议或愿望。 1 had better可以缩写为 ‘d better，可用于任何人称，无形式变 化，后接动词原形。如： You look pale. You’d better go to see a doctor. 你脸色苍白，最好去看看医生。 We’d better leave now. 我们最好现在就走。 2 had better的否定式：had better not，表示“最好不”。如： Lucy, you’d better not go out at night. 露西，你晚上最好不要出门。 We’d better not tell him about it. 我们最好别告诉他这件事。 Answer the questions with should.
