Unit 9 Human Biology Lesson 2 Brain Power 教材分析 本课两段听力材料分别介绍关于大脑的基本知识以及关于如何提高大脑效率的建议。 教学目标 在本课学习结束时,学生能够: 1. 通过读和听获取相关信息; 2. 使用特定表达征求建议并给出建议; 3. 给出关于如何利用好大脑的建议。 教学重难点 【教学重点】 1. 学生能够通过读和听获取相关信息; 2. 学生能够使用特定表达征求建议并给出建议。 【教学难点】 学生能够给出关于如何利用好大脑的建议。 教学过程 Step 1 Warming-up Work in pairs and match the words from the box with their definitions. 设计意图:为即将展开的话题作词汇准备。 Step 2 Pre-listening Before listening to a lecture about the brain, read the statements and predict whether they are true or not. 设计意图:听前浏览题干,提取关键信息,预测听力内容,为接下来的听力活动做好充分准备。 Step 3 While-listening 1. Listen to the lecture and check your answers. Correct the false ones. 2. Listen again. Complete the information you hear about the brain. Then tell your partner what you have learnt about the brain. 3. Complete the summary with the words from the lecture. 设计意图:通过听取关键信息,帮助学生理解关于大脑的基本知识。 4. Listen to a student phone-in programme and complete the table. 5. Listen and imitate. Complete the Talk Builder. 设计意图:通过听力内容,帮助学生感知并学习征询建议和给出建议的表达方法。 Step 4 Speaking Work in groups for more ways to increase brain power. Then give a short presentation to the class. 设计意图: 学生进行输出,巩固本堂课所学。 Step 5 Assignment Recall what you have learned in the class and write a short passage about how to increase brain power. 设计意图: 在说的基础上,进行归纳整理,提升学生的逻辑思维能力及表达能力。 watch a video Recall what you have learned in the class and write a short passage about how to increase brain power.
