UNIT 7 Period 4 （Section B 2a-2e）教学详案

Period 4 （Section B 2a-2e）
设计说明
　　本课的阅读篇目具有说明文的一些特征。在做读前活动时，让学生分组利用2a提供的一些词汇，自己组织语言说一说大熊猫，为2b的阅读活动做好话题准备。2b、2c要求学生用寻读法完成任务。首先要求学生快速寻读2b文章，找出数字分别对应的内容，再引导学生用完整的句子表达这些数字的含义。然后让学生阅读2c的五个问题，在充分理解问题的基础上分段快速寻读文章，找出关键信息，并在问题后写出简略答语。2d要求学生仔细阅读2b文章，尽可能记住文章的细节，再用文章中的语言将2d的句子补充完整，朗读并核对答案，进一步巩固所学内容。学生在仔细阅读的时候，会遇到一些理解上的问题，因此要对一些知识点或难点进行讲解。为了帮助学生更深入地理解文章，让学生再次阅读文章，可以一边读一边完成框架图，然后鼓励学生用自己的语言复述课文。2e是在学生深入理解文章的基础上，导入保护大熊猫的话题。让学生进行分组讨论后，集中展示，达到语言输出的目的，同时提高保护动物的意识。

当堂达标（见导学案“当堂达标”）
答案与解析：
Ⅰ. 1. less　由much和than可知应用比较级；little的比较级为less。
2. keepers　句意为“其他的大熊猫饲养员正在准备牛奶作为大熊猫宝宝的早餐”。由be动词are可知，可数名词keeper应用复数形式。
3. babies　most of意为“……的大多数”，其后可数名词应用复数形式。baby的复数形式为babies。
4. illness　her为形容词性物主代词，修饰名词。ill的名词形式为illness。
5. awake　awake形容词，意为“醒着”，常作表语。前面有was，故用awake作表语。
Ⅱ. 1. D　walk into 意为“走路时撞着”。
2. B　die of 意为“死于（内因）”；die from意为“死于 （外因）”，由traffic accident（交通事故）可知，是外因，故选B。
3. A　“主语 + 谓语+数词 + times + as +形容词或副词原级+ as +被比较的内容”表示倍数，故选A。
4. D　with excitement 意为“兴奋地”。句意：当粉丝们看到这个有名的歌手时，他们兴奋地呼喊起来。
5. C　prepare... for... 意为“为……准备……”，为固定搭配。句意：我们必须为客人们准备一个房间。
