UNIT 4　The Internet Connects Us
Unit Review
设计说明 首先老师引领学生回顾本单元的重点词汇，为接下来的习题做好铺垫。紧接着做有关词汇的练习，检验掌握情况。讲解本单元的重要语法点——if引导的条件状语从句，尤其让学生记住并理解从句的时态，这是个难点也是重点。接下来，让学生进行笔头练习，学会用if连接句子并造句。学生在造句的同时更能切身体会语言的用法。然后设置听力活动，培养语感并提升听力能力。接下来，安排有趣而激烈的小组辩论活动，这既能锻炼学生用英语表达观点的能力，又能培养他们辩证思考的能力。设置阅读环节，让学生阅读文章并判断正误，锻炼学生提取关键信息的能力。最后设置部分练习，当堂检测学生的掌握情况。 教学目标 通过本课节的教学，学生达成以下目标： 1.知识目标 复习本单元所学的单词、短语和句型； 掌握本单元的语法：if引导的条件状语从句。 2.能力目标 能够谈论事物的两面性。 3.情感目标 任何事物都有两面性，看待事物要用辩证的思维方式。 重点难点 1.重点：复习本单元所学的单词、短语和句型； 掌握本单元的语法：if引导的条件状语从句。 2.难点：能够谈论事物的两面性。 教学准备 PPT 课件；本课节用到的录音。 授课时数 1课时 教学过程 Step 1　Revision Ask the students to write down the answers as quickly as possible.
