3. To know more about John Snow and

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. 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

clearly related to cholera, collected
information and was able to tie cases
outside the area to the polluted water.Answer these questions.p3 22 Do you think John Snow would have
solved this problem without the map?
Give a reason.No. The map helped John Snow organize
his ideas. He was able to identify those
households that had had many deaths
and check their water-drinking habits.
He identified those houses that had had
no deaths and surveyed their drinking
habits. The evidence clearly pointed to
the polluted water being the cause.3 Cholera was a 19th century disease. What disease do you think is similar to cholera today? Why?Three diseases, which are similar today,
are SARS, AIDS and bird flu, because
they are serious, have an unknown
cause and need public health care to
solve them.Careful reading重难点句式分析1. He knew that cholera would never be

5. Read the following passage and copy
it into your notebook. Pay attention
to the coloured words.Here is an astonishing and significant fact: Mental work alone can’t make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human brain could labor without reaching a stage of fatigue (疲劳).To the amazement of these scientists, they discovered that blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day laborer, we would find it full of fatigue toxins (毒素) and fatigue products. But if we took blood from the brain of an Albert Einstein, it would show no fatigue toxins at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning. The brain is totally 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 England’s 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 physical 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.
