问题 It is estimated that the disease ______ by polluted water will kill 1 out of every 100 children.

选项 A、causing
B、caused
C、to cause
D、will cause

答案B

解析 本题考查非谓语动词。句意:据估计,这个由被污染的水引起的疾病将会使百分之一的孩子丧命。the disease和cause之间为被动关系,应用过去分词,caused符合题意。现在分词causing表示主动;不定式to cause表目的;will cause是谓语动词形式,皆不符合题意,故本题选B。
