America is in no immediate danger of "running out of water". People in the West have been aware that water is a precious commodity and must be conserved. In the damp East, an excess of water led to complacency until two factors created concern over our water supply. First, the periods of drought from the 1961 to 1966 in the Northeast affected crop production and used up the surface and ground water supplies. Second, attention was called to rapid increases in the rates of pollution of these waters resulting from increased urban and industrial growth. As a result, there is an increasing awareness of the need for conserving the quantity and quality of our nation's water supplies.

Water is a renewable resource, but it is not exhaustible. When used for municipal, industrial, or agricultural purposes, it is not destroyed, but generally finds its way back into our water supply. This used water now carries some waste materials. These dirty waters are often dumped into large bodies of water or are disposed of on land. In the latter instance, evaporation concentrates some of the wastes on the soil surface. On the other hand, water moving through the soil will eventually carry some of the wastes down into the ground water supplies, Eventually, all water evaporates and later returns to the earth as rain or snow in a relatively purer state.

Through this never-ending cycle, there is just as much water in this country now as there ever was. The amount, however, does not increase. Our rapid population growth and our agricultural and industrial expansion have caused our water needs to soar. By withdrawing water from streams too quickly, we have in some instances upset the balance of nature's built-in renewal processes for conserving water. As a result, some of our streams and lakes have become "wet deserts." There is still plenty of water in them, but its water is so polluted that it supports almost no life at all.

1.The passage is mainly about_____.

A. water resources of the United States

B. the renewal processes of water in mature

C. the importance of water conservation

D.water pollution in America

2. The word "drought" in the sentence "First, the periods of drought---ground water supplies." Most probably means_____.

A. catastrophe of too much rain

B. danger of running out of water

C. calamity dry weather

D. damage caused by typhoon

3. Water is relatively purer in_____.

A. fast moving streams and rivers

B. underground water supplies

C. mountainous areas

D. rain and snow

4. When the author says that lakes have become "wet deserts",._____

A. he is being angry

B. he is being optimistic

C. he is being sad

D. he is being humorous

5. It is implied in the passage that______

A. water can be polluted by deserts

B. there are many water conservation programs in America

C. water keeps evaporating from the earth's surface

D. water is not polluted by waster materials

[难点]

1.run out of　　用完，耗尽

[答案]

1.C

考点：这是一道典型的文章主旨题。

解析：文章第一段的最后一句话是文章的中心思想，指出人们越来越意识到保护水的量和质的必要性。第二、三段主要讨论节约用水和水污染 的危害。第二段指出，水虽然百一种可再生的资源，但并不是用之不竭;第三段说，人口的急剧增加，工农业的快速发展使得用水需求高涨并造成严重的水污染。综上所述，我们可以看出，文章主要讨论保护水资源的重要性。选项A、B、D都是以偏概全。

2.C

考点：这是一道理解题。

解析：题目要求猜测"drought"一词的含义，我们可以通过这个词的上下文来理解它的意思。文章第一段第四句说，1961至1966年东北部地区的drought影响了农作物的生产，使地表水和地下水供应枯竭。据此我们可以推断出这个词的含义是旱灾。

3.D

考点：这是一道细节题。

解析：答案在文章第二段的最一句："Eventually, all water evaporates and later returns to the earth as rain or snow in a relatively purer state."(最终所有的水蒸发，然后以更加纯净的形式降雨或降雪回到地球。)

4.D

考点：此题考察学生对作者态度的理解。

解析：文章第三段最后一句很好地解释了"wet desert"的含义，即：一些河流、湖泊中有大量的水，但污染非常严重，几乎所有的生物都不能使用。根据这个解释，我们可以理解作者说这番话的心情，作者面对这样一种情况只能感到悲哀，而不是愤怒，因为愤怒无济于事，更不是感到乐观或幽默。

5.C

考点：此题考察学生的判断能力。

解析：根据文章第二段的最后一句："Eventually, all water evaporates and later returns to the earth as rain or snow in a relatively purer state."，我们可以推断出水不停地从地球表面蒸发掉，然后在高空中变成水的固态形式。选项A和D与文章内容不符。选项B在文章中没有提及。

Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A ), B), C) or D ) . You should make the correct choice and mark the corresponding letter on the Answer Sheet with a single line through the center.

Packaging is a very important form of advertising. A package can sometimes motivate people to buy products. For example, a little child might ask for a breakfast food contained in a box with a picture of a TV character. The child is more interested in the picture than in breakfast food. Pictures for children to color or cut out, games printed on a package, or a small gift inside a box also motivate many children to buy products - or to ask their parents to buy for them.

Some packages suggest that a buyer will get something for nothing. Food products sold in reusable containers are examples of this. Although a similar product in plain container might cost less, people often prefer to buy the product in a reusable glass or dish, because they believe the container is free. However, the cost of the container is added to the cost of the product.

The size of a package also motivates a buyer. Maybe the package has"Economy Size"or"Family Size"printed on it. This suggests that the larger size has the most product for the least money. But that is not always true. To find it out, a buyer has to know how the product is sold and the price of the basic unit.

The information on the package should provide some answers. But the important thing for any buyer to remember is that a package is often an advertisement. The words and pictures do not tell the whole story. Only the product inside can do that.

36."A buyer will get something for nothing"in paragraph 2 may probably mean ________.

A) a buyer will not get what he pays for

B)a buyer will get more than what he pays for

C) a buyer will get something useful free of charge

D) a buyer will get more but pay less

37. From the pasage we know the buyer pays more attention to ________.

A) the size of a container

B) a container with attractive picture

C) a well-designed container

D) a plain container with low cost

38. What suggestion does the writer give in the passage?

A) It's not good to buy the product which is sold in a glass or dish.

B) The quality of a container has nothing to do with the quality of the product.

C) The best choice for a buyer is to buy a product in a plain package.

D) A buyer should buy what he needs most rather than a well-designed package.

39. Which of the following sentences is NOT true according to the passage?

A) In fact glasses or dishes used for packaging do not cost money at all.

B)"Family Size"printed on the package means that it is rather economic.

C) To a child, even to an adult, the form is far more important than the content.

D) Words and pictures written on the package are thought to be an advertisement.

40. What do you think is the best title for the passage?

A) How to Package a Product.

B) How to Make an Advertisement.

C) How to Sell Product.

D) How to Attract More Buyers.

答案及精解

36.【答案精解】A。推理题。这句话的意思是"有的购买者买一件东西，却什么也不图。"隐藏的意思是他们只看包装不看实物，是物非所值的购物方式。只有选项A是表达的这种意思，其他几个选项意思近似。

37.【答案精解】C。推理题。整篇文章讲的是包装就是广告。包装诱惑人进行购买，为什么人们会购买呢，主要是因为人们对好的包装感兴趣，通常认为他们是免费的。

38.【答案精解】D。推理题。最后一段，作者提示读者The words and pictures do not tell the whole story.Only the product inside Call do that.也就是说不要太相信广告词和图，要看产品本身。

39.【答案精解】A。判断题。第二段最后一句However，the cost of the container is added to the cost of the product，说明所有包装的成本都是算入产品价格的，选项A说包装的玻璃碟子不花钱，这是不正确的。

40.【答案精解】A。主旨题。本文是讲包装让购物者产生购物冲动的问题，它包含了两层意思，一是对于消费者来说，要注意不要只看包装不看内容;二是对于卖家来说，就是要注意如何包装产品了。因此A更符合这篇文章的标题。

Directions:

You should write your responses to both Part A and Part B of this section on ANSWER SHEET 2.

your teacher. Your letter should include:

1 ) apologize for your failure to keep the appointment

56.范文

Dear Prof.Wan9，

First of all，please allow me to express my deep sorry for not being able to keep our appointment.I do know that this is very impolite and must have caused you much trouble.

I do reckon that at present any explanation is pale and futile.However， I do not want you to misunderstand me.On my way to your office，an old lady suddenly fainted due to heart attack on the bus.I stopped a taxi and sent her into a nearby hospital.I stayed there until her son came，which spoiled our appointment.

I am aware that our appointment is of importance.I do hope that you would be kind enough to spare your valuable time to meet me.I anl looking forward to hearing from you.

Sincerely yours，

LiMing
