Forest fire 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..本文语法:现在完成进行时一句话总结:现在完成进行时表示过去某时开始发生,一直延续到现在并且可能继续发生下去的动作。

新概念英语第二册:第53课课文详解及语法解析课文详注 Further notes on the text
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。
(1)at last(终于,到底)表示经过一番努力之后。
(2)put out能够表示“扑灭”、“熄灭”、“关掉”等含义:
Please put the light/ fire out.
请把灯关掉/把火灭掉。
(3)forest虽然是名词,但在句中起形容词的作用,修饰fire。
2.…they have been trying to find out how the fire began.……他们一直试图找出起火的原因。
(1)短语动词find out表示经过研究、努力等“发现”、“找出”、“查出”:
I'll try and find out the name of the person who saved my life yesterday.
我将设法查出昨天救我命的那个人的姓名。
(2)how the fire began是find out的宾语,它是一个由疑问词how引导的名词从句。
3.They were also quite sure that a cigarette end did not start the fire.他们还十分肯定火灾也不是由烟头引起的。
(1)start作及物动词时能够表示“使……发生”、“引起”。
(2)be sure后面跟的是名词从句。
that引导的这个名词从句也能够写成that the fire was not started by a cigarette end。
但
这里强调的是引起火灾的原因(不是碎玻璃或烟头),所以用烟头作主语。
4.…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(某个已经存有的东西)的含义:
I don't know who discovered America.
我不知道谁发现美洲的。
在discover前面加上accidentally更增强了“偶然”、“意外”的含义。

lake.
村民们惊讶地发现湖边有一架飞机的残骸。

Did you wind this piece of wire round the tree?
是你把这根铁丝缠在树上的吗?
(3)wire指具体的电线、铁丝等,line在这里指“线路”,含义
比wire广。
6.When it did so…当它这样做时……
so常用于一些动词之后,代指前面提过的某个动作/某件事,以免重复:
Has Susan got into university?
苏珊上大学了吗?
I believe/think so.
我想是的。
