分析 约翰.斯诺曾经是伦敦一名著名的医生.他想发现霍乱的起因.当时有两种看法,斯诺对这两种推测都很感兴趣.第一种看法是霍乱病毒在空气中繁殖着,.第二种看法是人们在吃饭的时候把这种病毒引入体内.约翰.斯诺调查了这两条街的水源情况.他发现,水是从河里打来的,而河水被伦敦排出的脏水污染了.约翰.斯诺马上叫宽街上惊慌失措的老百姓拆掉水泵的把手.这样,水泵就用不成了.不久,疫情就得到了缓解.最后,"霍乱王"终于被击败了.
解答 61.exposed 考查过去分词.people与expose之间是动宾关系,用过去分词短语exposed to cholera which was the deadly disease of its day作后置定语.
62.believed 考查动词语态.it与believe之间是动宾关系,用一般过去时的被动语态.it是形式主语,真正的主语是that从句.
63.Suspecting 考查现在分词.he与suspect之间是主谓关系,用现在分词作状语.
64.to blame 考查动词不定式.be to blame意为"该受责备(应负责任)",是固定搭配,主动形式表示被动意义.
65.where 考查定语从句.分析句子结构可知这是一个定语从句,先行词two streets在从句中作地点状语,用关系副词where.
66.when 考查连词.根据句意:当他发现水是从河里来的…时.用连词when引导时间状语从句.
67.astonished 考查过去分词.过去分词转换的形容词常常修饰人或者与人有关的事物.
68.it 考查代词.it指代句中的the handle.
69.deaths 考查名词复数.介词from后接名词,death是可数名词,其前有数词two修饰时用复数形式.
70.certainty 考查固定搭配.with certainty意为"确定无疑地",是固定搭配.
