Reading Tips

在阅读时，要注意综合运用略读 (skimming) 与扫读(scanning) 这两种方法。

略读 (skimming) 只看文章标题、下标题以及每个部分或者段落第一行，关注文章中反复出现的关键词。 略读时，要用充足的时间读懂段落的第一句和第二句，因为第一句往往是该段的主题句 (topic sentence) ，而第二句往往是对前句的延伸 (extension)或进一步的解释 (explanation) 。

通过略读把握文章大意

运用扫读 (scanning) 迅速浏览从第三句开始的后面部分 , 搜寻作者对开头两句的支持句(supporting sentences), 并同时注意文章中间是否有转折词 (transition), 因为这些词常常会把文章的思路逆转或加入其它重要的信息。当读到段落的最后一句时 , 我们又要使用略读 , 这时必须再次放慢速度 (slow down your pace) 直到完全消化作者对段落的小结(conclusion), 因为该小结有可能与主题句截然相反或引导读者进入下一个段落。
