Lesson 1 A puma at large

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.

Pay attention: The points below are not covered by the mp3. It is better for you to listen to the mp3 first and try to take notes by yourselves.

1，a puma at large

at large

1：逃遁的，没有被控制的。

2：详细的(in detail)

3：总体来讲（as a whole）

2，Pumas are large, cat-like animals which are found in America.

tip: 在英文的表达方式中，首先呈现给读者的是结果。写议论文的时候要注意把握观点。 体会课文第一二句话，乃至第一段在全文中的作用。

cat-like 像猫的，偷偷摸摸的

life-like 栩栩如生的

3，When report came into London zoo... 当伦敦动物园接到报告......

同种结构的句型：(An idea) come to sb.某人突然想到了......

4， They were not taken seriously.

take sth. seriously: deal with sth. seriously 认真（严肃）对待某事

take sth. lightly 草率对待某事

注意：例句的they指的是reports, 意思是：The experts did not take the reports seriously.

5, The descriptions given by people who claimed to have seen the puma were extraordinarily similar.

claim to have done sth 声称曾经做过某事

6， Experts confirmed that a puma will not attack a human being unless it is cornered.

confirm: be sure, be certain

7，The search proved difficult.

这个语境中：search=hunt

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

leave behind: 把某物留在后面

9， A businessman on a fishing trip saw the puma up a tree.

on + 名词：强调动作正在进行

on the rise:在上升

on the increase: 在增加

on the watch: 在观看

on the match:在比赛中

on the fishing trip:在钓鱼的途中

on holiday: 在度假

10， The experts were now fully convinced that the animal was a puma. fully: completely, entirely

11，This one must have been in the possession of a private collector.

in the possession of sb==in sb's possession 归某人所有

in possession of sth. 拥有某物

take possession of 拥有

tip: 请大家体会下同种意思的不同表达，让我们的语言丰富起来！

eg: The beautiful car is in my possession / in the possession of me.

I am in possession of the beautiful car.

The person in possession of the big house is excited.

12， It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside.

It is disturbing to think that 一想到.........就心里不安 1. simple sentence, compound sentence and complex sentence(check NCE2 L73)

本文主要有复杂句组成，复杂句是由简单句构成的，分析复杂句的意思：

1）先看句子由几个部分组成；

2）通过link word来判断主从句关系；

e.g. 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.

分句1：The evident began to accumulate.

as 表示伴随主句同时发生的状态

主句：Experts from the Zoo felt obliged to investigate.

tip: 在阅读中，先看主句有助于全文理解和提高阅读效率。

分句2：The descriptions given by people who claimed to have seen the puma were extraordinarily similar.

for 表示原因，翻译做：因为

这个分句还可以再细分：

句子的主干部分是：The descriptions were similar

given引导的部分是过去分词作定语，修饰description

而这一成分中，who引导的定语从句，用来修饰people

2.被动语态常用于表达事实的客观性

tip: 英文的表达方式重点在于突出客观事实，故常用被动语态；而中文则善于运用动作的执行者,常用主动式 被动语态的特殊结构：被动语态＋现在分词

e.g. puma fur was found clinging to bushes 现在分词clinging起补充说明主语的作用

3，定语从句和同位语从句

一般来讲, 定语从句和同位语从句紧随在被修饰名词后面，但为了保持句子平衡，也可把谓语动词放到从句之前。让我们来看两个文中的例子：

(1)Pumas are large, cat-like animals which are found in America.

(2)Reports came into London Zoo that a wild puma had been spotted forty-five miles south of London.

现在让我们来回顾下两种从句的区别：

(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

表达事物：that(也可指人)/ 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、宾语时，关系词用that 而不是which

Lesson 7 Mutilated ladies*残钞鉴别组

Has it ever happened to you? Have you ever put your trousers in the washing machine and then remembered there was a large bank note in your back pocket? When you rescued your trousers, did you find the note was whiter than white? People who live in Britain needn't despair when they make mistakes like this (and a lot of people do)! Fortunately for them, the Bank of England has a team called Mutilated Ladies which deals with claims from people who fed their money to a machine or to their dog. Dogs, it seems, love to chew up money!

A recent case concerns Jane Butlin whose fiancé, John, runs a successful furniture business. John had a very good day and put his wallet containing ￡3,000 into the microwave oven for safekeeping. Then he and Jane went

horse-riding. When they got home, Jane cooked their dinner in the microwave oven and without realizing it, cooked her fiancé's wallet as well. Imagine their dismay when they found a beautifully-cooked wallet and notes turned to ash! John went to see his bank manager who sent the remains of wallet and the money to the special department of the Bank of England in Newcastle: the Mutilated Ladies! They examined the remains and John got all his money back. ‘So long as there's something to identify, we will give people their money back,' said a spokeswoman for the Bank. ‘Last year, we paid ￡1.5m on 21,000 claims.'

* Damaged bank notes. The Queen's head appears on English bank notes, and ‘lady' refers to this.

（Attention：The following points are not covered by the video. It is better for you to watch the video or listen to the MP3 first and try to take notes on your own. Then you may check here to get more details. ）

1, Has it ever happened to you? Have you ever put your trousers in the washing machine and then remembered there was a large bank note in your back pocket?

段首或段尾运用疑问句提出问题的作用：

段首--主要要引起读者的兴趣和注意力

段尾--进一步巩固、加深与本段所涉及的内容，进一步引起读者的沉思

2, When you rescued your trousers, did you find the note was whiter than white? rescue 救援，援救

e.g. Hundreds of people went to rescue the survivors of the plane crash. 这里rescue是一个大词，大词小用可以加强语气

whiter than white 这里表示damaged, mutilated的意思，中文是：损坏，残缺不全 3，People who live in Britain needn't despair when they make mistakes like this (and a lot of people do)!

needn't despair=needn't feel despaired

4，Fortunately for them, the Bank of England has a team called Mutilated Ladies which deals with claims from people who fed their money to a machine or to their dog.

Fortunately for them

相当于luckily / happily for them

deal with sth. 处理

make a claim for提出索赔,对（赔偿等）提出要求

feedsth. to 把某物喂给...

feed 的过去式和过去分词都是：fed

5，Dogs, it seems, love to chew up money!

it seems 似乎

本句把dogs提前，加强了语气，本句可还原成: It seems that dogs love to chew up money!

6，A recent case concerns Jane Butlin whose fiancé, John, runs a successful furniture business.

第二段充分说明了约翰是怎么样把钱从银行里拿回来

concern: 涉及到=is about

run a factory, run a company 经营工厂\公司

7，John had a very good day and put his wallet containing ￡3,000 into the microwave oven for safekeeping.

have a very good day

区别下面两个例句：

e.g. I had a very good day today. 我今天过得很好。

e.g. I had a good time today. 我今天玩得很好。

wallet containing...=wallet which contained....

for safekeeping...=to keep it safe 这里for表示一种目的

8, Then he and Jane went horse-riding.

go doing形式表示做某事

e.g. go horse-riding骑马；go fishing钓鱼；go hunting打猎；go shopping购物

9, Imagine their dismay when they found a beautifully-cooked wallet and notes turned to ash!

dismay: 沮丧

beautifully-cooked wallet: 这里用了一种讽刺的口吻，这是一种幽默的手法

turned to=turned into=become

10, ‘So long as there's something to identify, we will give people their money back,' said a spokeswoman for the Band. ‘Last year, we paid ￡1.5m on 21,000 claims.'

so long as=as long as=on condition that 表假设，只要...

paid ￡1.5m on 21,000 claims， on 强调对21000起索赔要求

Pay的几个词组：

pay money for:为...付款

e.g. We paid 80 dollars for the dictionary. 我们买字典花了80美元。

pay off 还清，偿还

e.g. The couple have already paid their debts off. 这对夫妻已经还清了债务。 pay back

(1) 把钱归还回去 pay money back

(2) 报仇，报复 pay somebody back

e.g. Don't say that again or I will pay you back. 别再说了，否则我就报复你。

三、考卷比较

本试卷新课标全国卷Ⅰ相比较，基本相似，具体表现在以下方面： 1. 对学生的考查要求上完全一致。

即在考查基础知识的同时，注重考查能力的原则，确立以能力立意命题的指导思想，将知识、能力和素质融为一体，全面检测考生的数学素养，既考查了考生对中学数学的基础知识、基本技能的掌握程度，又考查了对数学思想方法和数学本质的理解水平，符合考试大纲所提倡的“高考应有较高的信度、效度、必要的区分度和适当的难度”的原则． 2. 试题结构形式大体相同，即选择题12个，每题5分，填空题4 个，每题5分，解答题8个（必做题5个），其中第22，23，24题是三选一题。题型分值完全一样。选择题、填空题考查了复数、三角函数、简易逻辑、概率、解析几何、向量、框图、二项式定理、线性规划等知识点，大部分属于常规题型，是学生在平时训练中常见的类型．解答题中仍涵盖了数列，三角函数，立体何，解析几何，导数等重点内容。

3. 在考查范围上略有不同，如本试卷第3题，是一个积分题，尽管简单，但全国卷已经不考查了。
