培养猜词的能力，根据词根，上下等，尤其要注意单词及词组在上下中的含义，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hatanuinferfrthesendparagraph?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。这节也有一些亮点，比如：1这节阅读上出了英语新程标准的理念。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这节阅读把应试教育和素质教育结合起了。首先，在阅读时注重篇的理解，帮助学生理解结构（Briefintrdutin,Bdandnlusin）。其次，难句的突破在理解中带出，不是为了难句去讲难句。
