The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.

  Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.

  For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水區) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方體的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.

 

1.The author’s attitude towards the use of natural resources is _________.

    A. positive         B. uninterested     C. optimistic           D. critical

2.According to the author, the greatest mistake of our forefathers was that _________.

  A. they had no idea about scientific forestry

  B. they had little or no sense of environmental protection

  C. they were not aware of the importance of nature study

  D. they had no idea of how to make good use of raw materials

3.To avoid repeating the mistakes of our forefathers, the author suggests that _________.

  A. we plant more trees

  B. natural sciences be taught to everybody

  C. environmental education be directed toward everyone

  D. we return to nature

4.How can you understand the underlined sentence in the last paragraph?

A. Our living space on the earth is getting smaller and smaller.

B. Our living space should be measured in cubic volume.

C. We need to take some measures to protect space.

D. We must preserve good living conditions for both birds and animals.

When someone says, “Well, I guess I'll have to go to face the music,” it doesn’t mean he is planning to go to a concert. It is something far less pleasant, like being called in your boss to explain why you did this and did that, and why you did not do this or that. Terrible music, indeed, but it has to be faced. At some time or another, every one of us has had to “face the music”, especially as children. We can remember father’s angry voice: “I want to talk to you!” And only because we did not obey him. What an unpleasant business it was!
The phrase “face the music” is known to every American, old and young. It is at least one hundred years old. Where did the expression come from?
The first explanation came from the American novelist James Fenimore Cooper. He said, in 1851, that expression was first used by actors while waiting in the wings (舞臺的兩側) to go on stage. After they got their clue(暗示) to go on , they often said, “It’s time to go to face the music. ” And that is exactly what they did face the orchestra (樂隊) which was just below the stage.
An actor might be frightened or nervous as he moved on to the stage in front of the audience(觀眾) that might be friendly, or perhaps unfriendly, especially if he forgot his lines. But he had to go out. If he did not, there would be no play. So “face the music” came to mean: having to go through something, no matter how unpleasant the experience might be, because you knew you had no choice.
【小題1】The expression “face the music” means ______.

A. plan to go to a concert
B.get one’s clue to do something
C.have to go through something far less pleasant
D.disobey what one's father says
【小題2】The passage tells us that the expression was first used by _____.
A.childrenB.novelistsC.actorsD.audience
【小題3】In the last paragraph the Chinese meaning of the word “line” is _______.
A.老板B.同事C.角色D.臺詞

Ⅱ   閱讀(共兩節,滿分50分)
第一節:閱讀理解(共20小題;每小題2分,滿分40分)
閱讀下列短文,從每題所給的A、B、C和D項中,選出最佳選項,并在答題卡上將該項涂黑。
Parents have to do much less for their children today than they used to do,and home has become much less of a workshop. Clothes can be bought ready made; washing can go to the laundry; food can be bought; cooked,canned or preserved; bread is baked and delivered by the baker; milk arrives on the doorstep; meats can be had at the restaurant,the work’s canteen,and the school dining-room.
It is unusual now for father to pursue his trade or other employment at home,and his children rarely,if ever,see him at his place of work. Boys are therefore seldom trained to follow their father’s occupation,and in many towns they have a fairly wide choice of employment and so do girls. The young wage-earner often earns good money,and soon acquires a feeling of economic independence. In textile areas it has long been customary for mothers to go out to work,but this practice has become so widespread that the working mother is now a not unusual factor in a child’s home life,the number of married women in employment having more than doubled in the last twenty-five years. With mother earning and his older children drawing substantial wages father is seldom the dominant figure that he still was at the beginning of the century. When mother works, economic advantages accrue,but children lose something of great value if mother’s employment prevents her from being home to greet them when they return from school.
26. The writer mentions home as workshop because______.
A. fathers often pursue employment at home
B. parents had to make food and necessity themselves for their daily-life
C. many families produce goods at home for sale
D. both fathers and mothers and mothers in most families are workers
27. The writer says that home has become much less of a workshop. He means______.
A. in the past, home was more like a workshop
B. home is much more of a workshop now
C. home-workshops are becoming fewer and fewer
D. home was less like a workshop in the past
28. The word“accrue”in the sentence“When mother...accrue,”is closest in meaning to
__________________.
A. change                            B. dwindle                    C. double                     D. increase
29. The chief reason that boys are seldom trained to follow their father’s occupation is ___________________.
A. that children nowadays rarely see their fathers at their place of work
B. that fathers do not like to pursue employment at home any more
C. that there is a wide choice of employment for children
D. that children also like to have jobs outside
30. What makes father no longer the only dominant person in a family?
A. With their earning,mother and children do not need to depend on father for their life.
B. There are many choice of employment for mothers and children.
C. Father does much less for his children today than he used to.
D. The number of married women in employment has increased greatly now.

If you look up the word “create” in the dictionary , you will find it means “to bring into being, to cause to exist something each of us does daily”.
We are creative whenever we look at or think about something in a new way First, this includes an awareness of our surroundings.It means using all of our senses to become aware of our world.This may be as simple as being aware of color and texture(質地),as well as taste, when we plan a meal.Above all, it is the ability to notice things that others might miss.
A second part of creativity is an ability to see relationships among things.If we believe the expression,“There is nothing new under the sun, the creativity is remaking or recombining(重組) the old in new ways.”For example, we might do this by finding a more effective way to study or a better way to arrange our furniture, or we might make a new combination of camera lenses and filters to create an unusual photograph.
A third part of creativity is the courage and drive to make use of our new ideas, to ask for them to achieve some new results.To think up a new idea is one thing; to put the idea to work is another.

B
Supermarkets are trying out new computers that make shopping carts more intelligent(具備智能的). They will help shoppers find paper cups or toilet soap, and keep a record of the bill.
The touch-screen devices(觸摸屏裝置)are on show at the Food Marketing Institute’s exhibition here this week. “These devices are able to create value and get you around the store quicker,” said Michael Alexander, manager of Springboard Retail Networks Inc., which makes a smart cart computer called the Concierge.
Canadian stores will test the Concierge in July. A similar device, IBM’s “Shopping Buddy”, has recently been test-marketed at Stop & Shop stores in Massachusetts.
Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.
“The whole model is driven by advertisers’ need to get in front of shoppers,” said Alexander. “They’re not watching 30-second TV ads anymore.”
People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system(系統)that will organize the trip around the store. If you’re looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.
The device also keeps a record of what you buy. When you’re finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay.
The new computerized shopping assistants don’t come cheap. The Buddy devices will cost the average store about $ 160,000, and the Concierge will cost stores about $ 500 for each device.
59. The underlined word “They”(paragraph 1)refers to ______.
A. supermarkets  B. shop assistants   C. shopping carts   D. shop managers
60. Which of the following is the correct order of shopping with computerized shopping carts?
a. Start the system.                                    b. Make a shopping list.
c. Find the things you want.                       d. Go to a self-checkout stand.
A. abdc                 B. bacd                        C. acbd                        D. bcad
61. We can learn from the last paragraph that ______.
A. intelligent shopping carts cost a large sum of money
B. the Concierge is cheaper than the Buddy devices
C. shop assistants with computer knowledge are well paid
D. average stores prefer the Concierge to the Buddy devices
62. What might be the most suitable title for the text?
A. New age for supermarkets.
B. Concierge and Shopping Buddy.
C. New computers make shopping carts smarter.
D. Touch-screen devices make shopping enjoyable.

科目:高中英語 來源:2012屆福建省廈門六中高三12月月考英語試卷 題型:閱讀理解

There are over one million superstitions(迷信), and most people believe at least one or two of them.
Many people are superstitious about numbers. They think that there are lucky numbers and unlucky numbers.
The number 13 is often considered unlucky. In some parts of the world, buildings have no 13th floor and streets have no houses with the number 13. In Japan, "4" is considered unlucky because in Japanese the word "four" is pronounced the same as the word "death" .
Japanese never give gifts of four knives, four napkins, or four of anything.
What are the lucky numbers? Seven is a lucky number in many places, and "8" is considered a lucky number in Japan and China. In China, businesses often open on August 8, and many couples register to get married at eight past eight on August 8.
Superstitions about numbers are so widespread that some people--called numerologist--make a living by giving advice about numbers.
In 1937, when the Toyoda family of Japan wanted to form a car company, they asked a numerologist if "Toyoda" would be a good name for the company. The numerologist said it would not be. He explained that "Toyota" would be a better name for the company. The family took his advice. As a result, millions of people drive "Toyota" and not "Toyoda" .
There are many other kinds of superstitions. There are superstitions about eating, sleeping, sneezing and itching(抓癢). There are superstitions about animals and holidays and horseshoes.
There are even superstitions about superstitions. Those superstitions will tell people how to reverse bad luck.
When the Japanese bump heads, they immediately bump heads again. According to a Japanese superstition, the first-bump means their parents will die, but the second bump "erases" the first bump         
To reverse bad luck in general, people turn around three times, turn their pockets inside out, or put their hats on backwards.
In the United States, baseball players sometimes wear their caps backwards when their team is losing. It looks silly, but the baseball players do not mind if it helps them win the game.   
【小題1】It can be inferred that superstitions about numbers are           .

A.popular neither in Japan nor in China
B.popular only in Japan and in China
C.popular both in Japan and in China
D.causing great troubles both in Japan and in China
【小題2】The underlined word " reverse " means           .
A.change to bad luckB.cause to go in the opposite direction
C.change for the worseD.exchange
【小題3】If a Japanese purposely bumps his head again after an accidental bump, we can be sure that     .  
A.he is madB.he is happyC.he is superstitiousD.he is very sad
【小題4】The writer wrote this passage with the purpose of           .
A.persuading us to believe superstitions
B.showing us some facts of superstitions
C.showing us the magic power of number
D.showing us a numerologist
