A
Foxes and farmers have never got on well. These small dog-like animals have long been accused of killing farm animals. They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.
年高三上學(xué)期期中考查（英語）.files/image004.jpg)
Noisy confrontations between hunters and saboteurs have become so common that they are almost as much a part of hunting as the pursuit of foxes itself. But this year supporters of fox hunting face a much bigger threat to their sport. A Labor Party Member of the Parliament, Mike Foster, is trying to get Parliament to approve a new law which will make the hunting of wild animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.
56. Rich people in Britain have been hunting foxes________.
A. for recreation B. in the interests of the farmers
C. to limit the fox population D. to show off their wealth
57. What is special about fox hunting in Britain?
A. It involves the use of a deadly poison.
B. It is a costly event which rarely occurs.
C. The hunters have set rules to follow.
D. The hunters have to go through strict training.
58. Fox hunting opponents often interfere in the game _______.

B
One mistaken idea about business is that it can be treated as a game of perfect information. Quite the reverse. Business, politics, life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors, which would even puzzle best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.
60. The subject discussed in this text is
_________.
A. the
process of reaching decisions
B. the
difference between poker and chess.
C. the
secret of making good business plans
D. the value
of information in winning games
61. An important factor in a game of
imperfect information is ___________.
A. rules B.
luck C.
time D.
ideas
62. Which of the following can be used in place of “Quite the reverse”?
A. Quite
right. B. True
enough. C. Most
unlikely. D. Just the opposite.
63. In the writer’s opinion, when making business decisions one should
___________ .
A. put
perfect information before imperfect information
B. accept
the existence of unknown factors
C. regard
business as a game of chess
D. mix known
and unknown factors
C
Computer people talk a lot about the need for other people to become “computer-literate.” But not all experts (專家) agree that this is a good idea.

A.Computer learning should be made easier.
B.There should be more computer clubs for experts.
C.People should work harder to master computer use.

Supply and demand is perhaps one of the most basic concepts of economics and it is the backbone of a market economy. Demand refers to how much of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer. The quantity supplied refers to the amount of a certain goods producers are willing to supply when receiving a certain price. The relationship between price and how much of a goods or service is supplied to the market is known as the supply relationship. Price, therefore, is a reflection of supply and demand.
The law of demand states that, if all other factors remain equal, the higher the price of a product, the fewer people will demand that product. The amount of goods that buyers purchase at a higher price is less as the price of a product goes up, so does the opportunity cost of buying that product.
Like the law of demand, the law of supply shows the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied. Producers supply more at a higher price because selling a higher quantity at a higher price increases the whole income.
Now that we know the laws of supply and demand, let’s turn to an example to show how supply and demand affect price.
Imagine that a CD of your favorite band is sold for $20. Because the record company’s previous analysis showed that consumers will not demand CDs at a price higher than $20, only ten CDs were sold because the opportunity cost is too high for suppliers to produce more. If, however, the ten CDs are demanded by 20 people, the price will then rise. As a result, the rise in price should cause more CDs to be supplied as the supply relationship shows that the higher the price, the higher the quantity supplied. If, however, there are 30 CDs produced and demand is still at 20, the price will not be pushed up because the supply is more than the demand.
72. We know from the passage that changes in the prices of product cause changes in ______.
A. income and expense B. invention and production
C. market and society D. supply and demand
73. Look at the following tablet first, if it is up to you to make a decision to sell a widget(裝飾品), you should sell it for ______.

74. The last paragraph is mainly about the importance of ______.
A. a reasonable price B. finding enough producing material
C. finding out what consumers think about D. making out the demand at market
75. The text is written mainly _____.
A. to persuade people to buy more products
B. to let people know more about a CD
C. to explain the relationships between demand, supply and price
D. to tell people how to buy things reasonably
