Reading Tips
阅读时,可根据阅读任务的不同, 综合运用略读(skimming)与扫读 (scanning) 。提高快速阅读水平。

通过略读把握文章大意 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)。

通过扫读寻找特定信息或特定词组 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。

Skimming and scanning

Skimming and scanning are two fast reading skills to help to browse text and extract the key points. The skills require practice, but once you have got the hang of them you’ll find you can get through a substantial amount of reading in quite a short time. These reading methods make it easier for you to grasp large amounts of material, especially when you're previewing. They are also useful when you don't need to know every word.
