八年级英语下册Unit3《Couldyoupleasecleanyourroom》(讲)(含解析)(新版)人教新目标版

1、Unit 3 Could you please clean your room一、教材分析本单元的主要语言功能是礼貌地请求别人做某事和向他人请求允许做某事，语法项目是Could you please do?和Could I do?从教材的整合来说它是Can you do ?（表请求）和Can I do?（请求许可）的延续，只是表达更委婉，更有礼貌。从本单元来说，它既是本单元的基本语言内容，又为本单元知识扩展和综合语言运用奠定坚实的基础。本单元话题又贴近他们的生活，应该会有话可讲，有话要讲。二、重、难点知识点提示重点：让学生掌握词汇的运用以及用Could you please do?

Neither was the second.both ：两者都。如：Both of them are students.(他们都是学生）特殊句式： both andnone: 三者或三者
