板书设计
答辩题目解析
1.本节课开头你采用了猜谜的方式，为什么要这样设计?
【参考答案】
在课程导入部分，设计了猜谜的游戏，通过对计算机的描述，让学生猜测。这样做不仅可以激发学生学习的兴趣，还能为下面学习阅读篇章奠定基础。
2.试讲中你用到了略读和扫读两种方法，请简单介绍下?
【参考答案】
Skimming主要是用来抓住文章的主要要点的(chief points)，即找一篇文章的主旨大意或是文章的高潮，可通过抓住每一自然段的中心论点或中心句来判断一篇文章的大意。实际上，这就是一种整体阅读的方法。
Scanning为了寻找某一特定信息而大致地快速地浏览。在扫读之前要有明确的题目，根据题目找出定位词，然后再到文章里找相关信息，最后进行对比;我们没有必要从头到尾地、逐字逐句地阅读，只要找准定位词，快速地在文章内“扫描”出定位词，问题也就迎刃而解。
