Revision 完成Read and tick or cross T: Look, our classroom is mess now. 出示Read and write部分图片。 S: 完成tick练习。 T: Now, who can tell me: Where is the...? S: It’s on/in/under... T: The classroom is in a mess. It’s not beautiful now, what can we do? S: We can clean the clean the classroom. T: OK, let’s clean the classroom together. (板贴clean the classroom) (设计意图：一个帮助老师在乱糟糟的教室里找东西的情境，既复习了前面学过的目标句子，又引起本课要谈论的clean the classroom的话题。另外，通过教师的体式语和夸张的语气，让学生感知help这个生词，为后面的对话学习做好准备。) Presentation 1.Watch and think: T: Zhang Peng, Wbingbing, Mike and John will clean the classroom. What will they do? Let’s watch and find the answer. (播放课文视频) S: Watch and think T: What’s the difference between“let’s”and“let me” S: Let’s表示让我们，Let me 表示让我 T: The sentence begins with“let”, we call it“imperative sentence”. Behind the “let”，it always put the original form of the verb. Look, Zoom says: Let me turn on the light. Please say more sentences begin with “let” S: 学生尝试说更多的以let打头的祈使句。 （设计意图：在播放之前提出问题，一方面引起学生阅读的兴趣，另一方面培养学生带着问题认真倾听的习惯和迅速提取信息的能力；培养学生以问题为导向，抓关键词句的阅读能力，让学生对比例句，发现let’s和let me的差异，培养学生观察比较归纳的思维品质，让学生说更多的祈使句，培养语言运用的能力）
2.Read and find T: 出示Mike提水图: Look! The water is too heavy. Mike says: help! He wants somebody to help him. Look at the word: help, what does the letter e say? S: /e/ T: Try to spell: /h/-/elp/ S: Spell help. T: What does help mean here? S: 帮助 T: Read and find: Who will help Mike? What does he say? S: Read the dialogue then answer the question. (设计意图：图片串联前后两个环节，再次创设语境，帮助学生理解help的含义，同时，借助学生已有语音知识经验，尝试自己去拼读记忆help，让学生体会到学习的成就感。) 3.Fill in the blanks T: Please read again, then let’s fill in the blanks. S: Read and fill in the blanks. (设计意图：帮助学生熟悉课文，再次巩固本课重点let句型，让学生从整体上感知全文，了解英语的语言习惯。) |
