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.

任务配置：L0+L4

笔记：

1.知识点

（1）At last firemen have put out a big forest fire in California.消防队员们终于扑灭了加利福尼亚的一场森林大火。

at last(终于，到底)表示经过一番努力之后。

put out可以表示“扑灭”、“熄灭”、“关掉”等含义：Please put the light/ fire out.

（2）cigarette ends 香烟头

（3）He noticed the remains of a snake which was wound round the electric wires

of a 16,000-volt power line.他发现了缠绕在16，000伏高压线上的一条死蛇。

①the remains表示“尸体”、“残骸”，必须用复数形式

②wound为wind的过去分词。wind在这里不表示“蜿蜒”，而表示“卷在……上”、“缠绕”，常与around/round连用：

Did you wind this piece of wire round the tree?是你把这根铁丝缠在树上的吗?

③wire指具体的电线、铁丝等，line在这里指“线路”，含义比wire广。

④power line 高压线

练习感悟：

cigarette的重读音节原来在英式和美式英语中是不同的，英[ˌsɪɡəˈret] 美[ˈsɪɡəret]，平时常听到的是美式，今天听录音的英式一直觉得怪怪的。

今天的文章第一次听的时候有部分单词没办法听出来，只能大概猜出意思，其实都不是很难很少见的单词，但是在连读加上词组很陌生的情况下，就懵了。例如cigarette ends，前一半的香烟听懂了，但是与后面的end连读，我自己都不知道这是2个单词，压根没听出end。
