Explain :Skimming
This means looking quickly through a piece of writing to find the main idea without reading every word. It is still a good idea to read the first sentence in each paragraph a little more carefully.

作业布置：
1.完成大册p37---p39的习题。
2.完成大册和导学案里下一课时的预习任务。
3.课后熟读2b三遍
反思：
初中阶段的阅读教学应该贯彻于整个学习阶段。阅读能力的培养是一个循序渐进训练过程，任何一个阅读材料都可以拿来培养和训练学生的阅读技能。因此，在学生词汇量不足的情况下，进行阅读策略的指导是很有必要的，教师必须在平时就十分注重自身教学策略的运用和对学生阅读技巧的培养。
在本节课的教学过程中，我始终坚持 “以学生为主体”的教育思想，注重调动学生的积极性和主动参与的热情，组织学生合作学习，并且遵循“读前--读中---读后”的英语阅读教学模式，注重“以读养能”策略的指导与运用，达到了目标语言的教学效果。
