教后反思：
在高考阅读中，常常会出现对文中单词或词组词义的猜测，在平时的阅读教学中如何渗透对学生这一方面能力的培养，也是教师应该思考的一个问题。
平时有意识地培养猜词的能力，根据词根，上下文等，尤其要注意单词及词组在上下文中的含义，而不是仅仅它的字面含义。
同样，在高考阅读中还经常会有深层理解题，如whatcanyouinferfromthesecondparagraph?
所以阅读的要求不能仅停留在表面含义，更应挖掘潜藏的内涵。
在教学中，也应充分应试技巧的训练和培养。
这节课也有一些亮点，比如：
1.这节阅读课上出了英语新课程标准的理念。
在阅读之前先对内容进行预测，这符合阅读的一般规律，在阅读之前首先在头脑中形成一个信息包，为阅读做好准备。
2.这节阅读课把应试教育和素质教育结合起来了。
首先，在阅读时注重篇章的理解，帮助学生理解结构（Briefintroduction,Bodyandconclusion）。
其次，难句的突破在课文理解中带出，不是为了难句去讲难句。
