Unit6 Grammar课件2025-2026学年沪教版八年级英语下册

Revision What happened at Yangguang Junior High School last week? What special events / activities were there? Which of these did Zhang Xin take part in? How did it go? The school had its annual English Week. An English book fair, a treasure hunt, a speaking competition, an English play and a poster design competition. He took part in the poster design competition. It went very well—Zhang Xin won the competition. Before the competition, Zhang Xin asked his cousin Zhang Lei for advice. What advice do you think Zhang Lei gave? Observe and think 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. Let’s sum up the rules! We use should and had better with the base form of a verb. The negative form of had better is had better not. What did the teacher say? What does should mean here? Why shouldn’t Zhang Xin put too much information on the poster? We should pick something related to Chinese culture. should意为“应该”，表达合理、正确的建议。 If there is too much information on the poster, it will look messy. shouldn’t意为“不应该”，用于建议不做某件不合理的事。 What did Zhang Lei say about picking the topic? Why? What advice did Zhang Lei give his cousin at the end of the conversation? Why did he give that advice? You’d better not pick such a broad topic. had better意为“最好（做）……；还是（做）……为好”，在特定情境下表达强烈建议，用于竭力劝告他人。 It is difficult to write about such a big topic. You’d better start early. It can take a long time to make a poster. E.g. We should wear school uniforms at school. = We ought to wear school uniforms at school.

Which advice is the most helpful? Which is the most creative? Best Advisors! Summary In this lesson, we have learnt how to use should and had better to give advice. We can use should to express what is best or right to do. We can use had better to give strong advice in a particular situation. We use should and had better with the base form of a verb. The negative form of had better is had better not. 3 Su Mei is interested in taking part in the speech competition during English Week. Can you give her some suggestions?
