    Background
    What do you know about infectious diseases?
    Infections diseases can be spread to other people. They
    have an unknown cause and need public health care to solve them.Birdflu, SARS are infections diseases which are difficult to cure.
    Read paragraph 1-3 and answer questions:
    1.What do you know about Dr.John Snow's being well-
    known in London?
    He ___Queen Vitoria as her personal physician.
    2.From what disease did Londoners suffer in his age?
    3.Did pople know how to ___ the disease?
    4.When did Dr.Snow think the disease would be
    controlled?
    5.What was the second theory explaining how the disease
    killed people?
    6.How serious was the disease outbreak in London?
    1.But he became inspired when he thought about helping
    ordinary people exposed to cholera.
    但当他想到要帮助那些得了霍乱的普通老百姓时,他就感到很
    振奋。
    2.Neither its cause nor its cure was understood. So many
    thousands of terrified people died every thime there was an outbreak.
    人们既不知道它的病源,也不了解它的治疗方法,所以每次爆
    发霍乱的时候,就有大批惊恐的百姓病死。
    3.The second suggested that people absorbed this
    disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person died.第二种看法是吃饭的时候人们把这种病毒引入体内,病从胃里发作而迅速殃及全身,患者就会很快死去。
