7、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 youll 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

8、 material,especially when youre previewing.They are also useful when you dont need to know every word.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

9、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a general ideacertain informationtitles and headingsthe first and last sentences of paragraphs

38、tireless.So what makes us tired?Some scientists declare that most of our fatigue comes from our mental and emotional(情感的)attitudes.One of Englands most outstanding scientists,J.A.Hadfield,says,“The greater part of the fatigue from which we suffer is of mental origin.In fact,fatigue of purely physica

39、l origin is rare.”Dr.Brill,a famous American scientist,goes even further.He declares,“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”What kinds of emotions make sitting workers tired?Joy?Satisfaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of not being appreciated-those are the emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.
