Unit 4 Lesson 20 全课时教案教学内容：冀教版小学英语4A Lesson 20教学目标:知识与技能：本课要求学生掌握单词toy shop/clothes shop/fruit shop；句子:May I help you 会用课文中句子对话。情感态度价值观：通过创设情境激发,培养学生学习英语的兴趣。教学重点、难点：本课重点单词、句子、并会进行对话。教具准备:磁带、单词卡片 教学过程:Step 1: Greeting and review1. Greeting2. Review: lets go shopping. 这里的lets = let us比较 let us 与 lets: let us 的us既可指说话者一方（此时表示请求或命令），也可以指说话者和听话者双方（此时表示建议或劝诱，此用法在语体上较正式）；而 lets 中的s(=us) 则只能指说话者和听话者双方（表示建议或劝诱），不能指说话者一方（即不能用来表示命令或请求）。比较：让我们告诉你我们在博物馆里看到的情况。 误: Lets tell you what we saw in the museum. 正: Let us tell you what we saw in the museum. 我们做朋友吧。 正: Lets be friends.（较口语化） 正: Let us be friends.（较正式） 在反意问句中，表示请求或命令时，用 will you；表示建议或劝诱时，用 shall we。如：我们一起去游泳好吗? 正: Lets go swimming together, shall we?（较口语化） 正: Let us go swimming together, shall we?（较正式） 让我们跟你一起去好吗?
