[教案]unit1Greatscientists

1、Module 5 Unit 1 Great Scientists【教材分析】本单元的中心话题是“科学家如何以探索、钻研、无畏的科研精神验证未知的科学真理。” Warming up 和pre-reading激活背景知识，为进入阅读课文打好铺垫;阅读文章介绍英国著名医生John Snow是如何通过考察、分析、探究的科学方法发现并控制“霍乱”的。运用图式理论激活背景知识的过程，Doctor Zhong Nanshan SARS & Bird Fluinfectious diseasesCholera John Snow通过阅读，使学生学习解决问题的一般步骤，并用于指导其他学科的学习。之后进行

2、相关的语言学习和语法学习，对于课文语言点，采用老师引导式：课前布置学生找出重难点，堂上通过设计各种各样的情景要求学生使用课文出现的重难点回答问题，最后以填空、翻译、复述、使用所学重点造句等形式进行巩固，深入理解文章中的句子。语法教学根据三维语法教学理论所提倡的：“形式+ 意义+ 运用”相结合；把语法教到实处，教到使处。整个语法教学由单词、词组、句子、对话、段落到篇逐渐过渡，使学生能做到学以致用。听力部分主要培养学生的分析能力和组织语言的能力；而说的部分侧重于交际能力和说服能力，同时也为后面的写作打好基础。写作除了强调说理能力的培养，也强调了对学生收集信息、整理信息及传递信息的能力培养，通过引入
