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.学科网 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。通过扫读寻找特定信息或特定词组Reading strategyskimmingscanninga general
