(单选题)
What is the main idea of paragraph 4?
A.Shark-related deaths.
B.Measures to protect sharks.
C.Reasons for using shark nets.
D.Dangers for beach-goers
参考答案:C
参考解析:
概括归纳题。根据第四段第一句中的“One of the arguments in support of using shark nets is that just one shark-related death has been reported in Queensland since the 1960s.”可知,支持使用防鲨网的理由之一是上世纪60年代以来,昆士兰仅有一例与鲨鱼有关的死亡报告,由此可知本段主要讲的是使用防鲨网的原因。故选C。
