objectives ReadingTips 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 Skimmingandscanning Skimmingandscanningaretwofastreadingskillstohelptobrowsetextandextractthekeypoints Theskillsrequirepractice butonceyouhavegotthehangofthemyou llfindyoucangetthroughasubstantialamountofreadinginquiteashorttime Thesereadingmethodsmakeiteasierforyoutograsplargeamountsofmaterial especiallywhenyou repreviewing Theyarealsousefulwhenyoudon tneedtoknoweveryword 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 topicsentence 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 supportingsentences 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 slowdownyourpace 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 Readingstrategy skimming scanning ageneralidea certaininformation titlesandheadings
