Forest fires are often caused by broken glass or by cigarette ends which people carelessly throw away. Yesterday the firemen examined the ground carefully, but were not able to find any broken glass. They were also quite sure that a cigarette end did not start the fire. This morning, however, a firemen accidentally discovered the cause. He noticed the remains of a snake which was wound round the electric wires of a 16，000-volt power line. In this way, he was able to solve the mystery. The explanation was simple but very unusual.

新概念2 第53课…a fireman accidentally discovered the cause．……一个消防队员偶然发现了起火的原因。

discover本身含有偶然发现（某个已经存在的东西）的含义：I don't know who discovered America. 我不知道谁发现美洲的。

（1）the remains表示“尸体”、“残骸”，必须用复数形式：wound /wuːnd/为wind的过去分词。
