题目内容
6.As a well-known doctor in London,John Snow was willing to help ordinary people(61)exposed (expose) to cholera(霍乱).He knew that only when (62)the cause of it was found could the (63)deadly(dead) disease be controlled.He has two theories in mind explaining how cholera killed people.(64)Onewas that cholera multiplied in the air without reason; the other was(65)that people absorbed it into their bodies (66)with their meals.After many(67)failures(fail),he succeeded in finding that the drinking water was to blame because the river (68)had been polluted(pollute).Without delay John Snow told the people to remove the handle from the water pump (69)so that it could not be used.Soon the disease began to slow down.To prevent the disease from (70)happening(happen) again,the water companies were instructed not to expose people to polluted water any more.Finally"King Cholera"was defeated.
分析 这篇短文主要介绍了伦敦的一位知名医生发现霍乱疾病的病因的故事.在经过多次失败之后,他发现了水是霍乱疾病传播的主要途径.
解答 61.答案是exposed,考查非谓语,句意:作为一个伦敦知名的医生,John Snow愿意帮助暴露于霍乱中的普通人.此处expose和people是动宾关系,所以用过去分词作定语.故答案是exposed.
62.答案是the.考查冠词,句意:他知道只有当这种病的病因被发现了,这种致命的疾病才能得到控制.分析语境可知此处特指这种病的病因,故用定冠词,答案是the.
63.答案是deadly.考查形容词,分析语境可知此处用形容词作定语,修饰下文disease疾病.deadly致命的,所以答案是deadly.
64.答案是One.考查代词,联系后一句"the other"可知句意为:一个是霍乱不知为什么在空气中繁殖.所以用不定代词One泛指两个理论中的任何一个,故答案是one.
65.答案是that.考查表语从句,句意:另一个是人们伴随着吃饭吸入他们的身体.此处是表语从句,从句中不缺少句子成分且句意完整.所以用that引导表语从句,不作句子成分,故答案是that.
66.答案是with.考查介词,此处吸入霍乱病菌和吃饭是伴随性动作,所以填介词with表示"带有,伴随",故答案是with.
67.答案是failures.考查名词,句意:在许多次失败之后,他发现饮用水应该为此担责,因为河水已经被污染了.此处after是介词,后面接名词作宾语.failure失败,可数名词.联系前文many许多的,可知此处可数名词用复数,所以答案是failures.
68.答案是had been polluted.考查时态,此处原因状语从句的动作发生在主句动作之前,且强调对主句动作的影响,故从句中用过去完成时态.从句主语river是动作对象,故用被动语态.所以答案是had been polluted.
69.答案是so.考查连词,句意:John Snow立刻告诉人们把手从抽水机上拆掉,所以人们不能再用它.短语so that表示结果"所以",故答案是so.
70.答案是happening.考查固定短语,句意:为了防止这种疾病再次发生,prevent sb from doing sht是英语的固定搭配,意思是"阻止某人做某事".此处from是介词,后面接名词或者动名词作宾语.所以答案是happening.
