At last firemen have put out a big forest fire in California. Since then, they have been trying to find out how the fire began. 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 fireman 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. A bird had snatched up the snake from the ground and then dropped it on to the wires. The snake then wound itself round the wires. When it did so, it sent sparks down to the ground and these immediately started a fire.

消防员终于扑灭了加利福尼亚的一场森林大火，此后一直在调查起火原因。 森林火灾常由碎玻璃或人们随手扔掉的烟头引起。昨天，消防员仔细检查了地面，却没找到碎玻璃，也能肯定不是烟头惹的祸。 不过，今天早上，一名消防员意外发现了原因：一条蛇的残骸缠在一根一万六千伏的高压电线上。 这个发现解开了谜团。原因很简单，却十分少见。 一只鸟从地上抓起蛇，后来把它掉在电线上。蛇缠住电线，火星随之落到地面，立刻引发了火灾。
学完这一课
先沿这条线复述《触电的蛇》：灭火之后查原因 → 常见原因都排除了 → 电线上的蛇提供线索 → 找到罕见的解释 → 还原火灾怎样发生。再借一个结构讲自己的事：本句更关心做了多久，还是完成了多少？换自己的学习过程说一句。
