Lesson 01 A Puma at large

Lesson 01 A Puma at large 逃遁的美洲狮

Listen to the tape then answer the question below.

听录音，然后回答以下问题。

Where must the puma have come from?

Pumas are large, cat-like animals which are found in America. When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously. However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar.

The hunt for the puma began in a small village where a woman picking blackberries saw‘a large cat’only five yards away from her. It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered. The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening. Wherever it went, it left behind it a trail of dead deer and small animals like rabbits. Paw prints were seen in a number of places and puma fur was found clinging to bushes. Several people complained of‘cat-like noises’at night and a businessman on a fishing trip saw the puma up a tree. The experts were now fully convinced that the animal was a puma, but where had it come from? As no pumas had been reported missing from any zoo in the country, this one must have been in the possession of a private collector and somehow managed to escape. The hunt went on for several weeks, but the puma was not caught. It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside. New words and expressions 生词和短语

Notes on the text课文注释

1 at large是介词短语，此处表示“逍遥自在”、“行动自由”的意思。

2 When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, 当伦敦动物园接到报告说，在伦敦以南45英里的地方发现一头野生美洲狮时。这个从句中以that引导的从句是reports的同位语，用于进一步说明报告的内容。

3 feel obliged to do sth. 是“感到不得不做某事”的意思。

4 it left behind it a trail of, 它身后留下一串……。

a trail of作left的宾语，behind it是状语，提到宾语之前是为了使句子结构更紧凑。

5 puma fur was found clinging to bushes中，clinging是现在分词，此处作主语puma fur的主语补足语。下文中As no pumas had been reported missing…一句中，missing也是现在分词作主语补足语。

6 in the possession of, 为……所有。

参考译文

美洲狮是一种体形似猫的大动物，产于美洲。当伦敦动物园接到报告说，在伦敦以南45英里处发现一只美洲狮时，这些报告并没有受到重视。可是，随着证据越来越多，动物园的专家们感到有必要进行一番调查，因为凡是声称见到过美洲狮的人们所描述的情况竟是出奇地相似。

搜寻美洲狮的工作是从一座小村庄开始的。那里的一位妇女在采摘黑莓时看见“一只大猫”，离她仅5码远，她刚看见它，它就立刻逃走了。专家证实，美洲狮除非被逼得走投无路，是决不会伤人的。事实上搜寻工作很困难，因为常常是早晨在甲地发现那只美洲狮，晚上却在20英里外的乙地发现它的踪迹。无论它走到哪儿，一路上总会留下一串死鹿以及死兔子之类的小动物。在许多地方看见了爪印，灌木丛中也发现了粘在上面的美洲狮毛。有人抱怨说夜里听见了“像猫一样的叫声”；一位商人去钓鱼，看见那只美洲狮在树上。专家们如今已经完全肯定那只动物就是美洲狮，但它是从哪儿来的呢？由于全国动物园没有一家报告丢了美洲狮，因此那只美洲狮一定是某位私人收藏家豢养的，不知怎么设法逃出来了。搜寻工作进行了好几个星期，但始终未能逮住那只美洲狮。想到在宁静的乡村里有一头危险的野兽继续逍遥流窜，真令人担心。

When reports came into London Zoo that a wild puma had been spotted forty-five miles

谓语动词放到从句之前

1> 定语从句只是对于被修饰词的补充说明、修饰

-- 定语从句的引导词：

-- 指人：主语who；宾语who, whom；定语 whose

-- 指物：that （也可以指人）/ which

-- 时间状语：when / 地点状语：where / 原因状语：why

2> 同位语从句则是讲述被修饰名词的内容

-- 同位语从句的引导词：

-- 名词(做主语、宾语等)：关系词用that 而不是which

-- 时间：when；地点：where

-- 定语从句中没有what 这个关系词，但what 可以引导同位语从句

-- An idea came to her that she might do the experiment in another way.

-- I have no idea what has happened to him。

they were not taken seriously （they指代reports ）

take sth seriously = deal with sth seriously 认真地对待某事

However, as the evidence began to accumulate, experts from the Zoo felt obliged to

investigate, for the descriptions given by people who claimed to have seen the puma were

extraordinarily similar.

However adv.然而(起转折作用)

As 连词：随着, 当...之时

过去分词做定语：

-- the descriptions given by people

-- the story told by the sailor (n.海员, 水手, 船员)

-- a book written by Luxun

claim to have done sth 声称曾经做过某事

-- He claimed to have been the manager of the large shop.

The hunt for the puma began in a small village where a woman picking blackberries saw

'a large cat' only five yards away from her.

Where a woman picking…定语从句

-- I still remember the school where I studied English.

It immediately ran away when she saw it, and experts confirmed that a puma will not attack

a human being unless it is cornered.

Confirm = be sure = be certain (confirm vt.确定)

Unless it is cornered = if it is not cornered (unless conj.如果不, 除非)

-- He will accept the job unless the salary is too low.

The search proved difficult, for the puma was often observed at one place in the morning

and at another place twenty miles away in the evening.

search = hunt

Wherever it went, it left behind it a trail of dead deer and small animals like rabbits.

把某物留在后面：leave behind

-- Wherever he went, the wound left behind him a trail of blood. （n.血）

Paw prints were seen in a number of places and puma fur was found clinging to bushes.

英文表达方式习惯用被动语态, 突出客观事实。而中文则善于运用动作的执行者。

puma fur was found clinging to bushes. （被动）

-- clinging to bushes 是现在分词短语做宾补

Several people complained of "cat-like noises' at night and a businessman on a fishing trip

saw the puma up a tree.

complain of/about sth 抱怨某事

on+名词：强调动作正在进行

-- on the rise 在上升 / on the increase 在增加

The experts were now fully convinced that the animal was a puma, but where had it come

from?

Fully （adv.充分地, 完全地）= completely = entirely

As no pumas had been reported missing from any zoo in the country, this one must have

been in the possession of a private collector and somehow managed to escape.

sth be in the possession of sb = sth be in sb's possession 某物归某人所有(主语是物)

-- The beautiful car is in my possession.= The beautiful car is in the possession of me.

Sb be in possession of sth 某人拥有某物(主语是人)

-- I am in possession of the beautiful car. （in possession of… 做表语）

-- The person in possession of the big house is excited. （in possession of… 做定语）
