新概念英语第二册第53课-1课文解析1.At last firemen have put out a big forest fire inCalifornia.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 firebegan.……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 savedmy 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 notstart thefire.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:l don't know who discovered America.我不知道谁发现美洲的。

This has not been easy because I own over a thousand books. To make matters worse， the room is rather small，so I have temporarily put my books on the floor. At the moment， they cover every inch of floor space and I actually have to walk on them to get in or out of the room. A short while ago， my sister helped me to carry one of my old bookcases up the stairs. She went into my room and got a big surprise when she saw all those books on the floor. 'This is the prettiest carpet I have ever seen，' she said. She gazed at it for some time thenadded， 'You don't need bookcases at all. You can sit here in your spare time and read the carpet!' 【课⽂翻译】 我们刚刚搬进⼀所新房⼦，我⾟⾟苦苦地⼲了整整⼀个上午。
新概念英语第二册课后题答案详解Lesson531. c根据课文第二行… they have been trying to find out how the fire began 能够判断出只有c. wanted to find out what had caused the fire 最能说明消防队员仔细查看地面的原因，其他3个选择都不够全面。
2. d根据课文第10-12行A bird had snatched up the snake from the ground and then dropped it on to the wires… When it Idid so, it sent sparks down to the ground and these immediately started a fire 能够判断只有d. a snake which had been dropped on to the wires by a bird 与课文的实际内容相符，只有它是引起火灾的原因，其他3个选择都不符合课文的实际内容。
3. a只有a. since最合乎题目意思和语法。
因为本句是现在完成实行时，只有since引导的时间短语最适合于完成实行时态，表示“自从……以来”，所以应该选a.其他3个选择都不能引导合适的时间短语。
4. c本句表示时间的词是often, 表示经常性的动作，所以应该用一般现在时。
a. is causing 是实行时，b. has caused 是完成时，d. is caused by 是现在时被动语态，而本句需要主动语态。
只有c. causes 是一般现在时，第3人称单数形式，本句的主语Broken glass 是单数，所以c.最符合语法，所以选c.5. ca. almost certain(几乎肯定)，b. fairly certain(相当肯定)，c. completely certain(完全肯定)，d. nearly certain(几乎肯定)4个选择中只有c. 同前一句中的quite sure(十分确信)意义最接近，所以选c.6. c只有c. succeeded in solving it (成功解决了它)同前一句中的 was able to solve the mystery (解开了这个谜)的含义相同，所以c.是准确答案。
一、单词与短语mild: adj.温和的，温暖的；①adj.(天气等)温和的、温暖的；例句：We had a mild winter last yea r.去年我们度过了一个温暖的冬天。
②adj.(人性情等)温和的；例句：Tom is a mild man who never gets angry.汤姆性情温和从来不生气③adj.(食物等)味道淡的；例句：Try this mild soap.尝一下这味道清淡的汤。
always: adv.总是;always是一个常见的词也是一个经常考的词，关于always 这个词的考点需要掌握以下三点：①always与Sometimes、usually、regularly、often、every year、every week、every day等词及短语是一般现在时显著的标志。
②always有“一再、老是”的意思，这个词义在考试中也常考，它表示“对一种经常出现的情况或动作的一种厌烦情绪”如：He is always late for class:他上课总是迟到。
③关于always的一个常见的重点搭配形式：be always doing sth: 总是、、、它也表示“对一种经常出现的情况或动作的一种厌烦情绪”。
如：He is always asking silly questions.他总是问些愚蠢的问题。
方位的表达：east: n.东方；west: n.西方；south: n.南方；north: n.北方；补充：northeast东北；northwest西北；southeast东南；southwest 西南；另外在方位前一定要加定冠词the。
wet: adj.潮湿的；season: n.季节；best: adv.最；adj.最好的；n.最佳者，最好的东西；best这个词在英语中也是经常考的词，关于这个词在中学阶段应该重点掌握以下三点：①best 是形容词good和副词well的最高级形式表示“最好的”的意思。

【Text】 What caused the fire? 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 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. 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.
【课文翻译】 消防队员们终于扑灭了加利福尼亚的一场森林大火。从那时起，他们一直试图找出起火的原因。森林火灾时常由破碎的玻璃或人们随手扔掉的香烟头引起。昨天，消 防队员仔细查看了地面，但未能发现碎玻璃。他们还十分肯定火灾也不是由烟头引起的。然而今天上午，一个消防队员偶然发现了起火的原因。他发现了缠绕在 16,000伏高压线上的一条死蛇。就这样，他解开了起火之谜。解释很简单，却异乎寻常。一只鸟把蛇从地上抓起来，然后把它扔到了电线上。于是蛇就缠住了 几根电线。当它这样做时，把火花送到了地面，这些火花立刻引起了一场大火。
