问题 The _____ of the flood, which caused thousands of people to lose their houses, was 3 weeks of torrential rain.

选项 A、source
B、origin
C、root
D、resource

答案 B

解析 考查名词辨析。origin“起源,起因”,指事物后来发生、发展变化的最初起点,或指人的出身和血统,如:words of Latin origin(源于拉丁语的词)。source指河流、泉水等的发源地,常指抽象事物的根源或来源或资料、信息的出处或来源,如:the source of strength(力量的源泉)。root“本质,根本”喻指事物最初、最根本的起因,如:the root of all evil(万恶之源)。resource常以复数形式出现,表示“资源,财力”,如:natural resources(自然资源)。本句指洪水的“起因”,所以origin为正确答案。
