Through thorough investigation, Dr. John Snow was finally able to prove that the outbreak of Cholera _____ people’s drinking of polluted water

A.was close linked with

B.closely linked to

C.was close connected with

D.was closely linked with

答案及解析： D

解析：

试题

分析：考查固定词组，closely linked to意思“密切联系”， was  connected with意思“与……连接”， was closely linked with意思“与……息息相关”，句子意思“经过全面的调查，约翰博士雪最终能够证明霍乱的突然爆发与人们喝的被污染的水息息相关”，所以选D考点：考查固定词组

点评：句子Dr. John Snow was finally able to prove that the outbreak of Cholera was closely linked with people’s drinking of polluted water.是个关系代词that引导的宾语从句；

单词polluted，过去分词修饰water，表示被污染的水。
