第三部份：阅读理解（共两节，满分50分）第一节，阅读下列短文-优题课

Economics has long been known as an unpleasant science. But is any economist so dull as to criticize Christmas? At first glance, the holiday season in western economies seems a treat for those who are concerned with such things as GDP growth. After all, everyone is spending; in America, sellers make 25 % of their yearly sales and 60 % of their profits between Thanksgiving and Christmas. Even so, economists find something to worry about in the nature of the purchases being made.
Much of the holiday spending is on gifts for others. At the simplest level, giving gifts involves the giver's thinking of something that the receiver would like — he tries to guess her preferences, as economists say — and then buying the gift and delivering it. Yet this guessing of preferences is often done badly. Every year, ties go unworn and books unread. And even if a gift is enjoyed, it may not be what the receiver would have bought if they had spent the money themselves.
Interested in this mismatch between wants and gifts, in 1993 Joel Waldfogel, then an economist at Yale University, attempted to estimate the disparity(差距) in dollar terms. He asked students two questions at the end of a holiday season: first, estimate the total amount paid (by the givers) for all the holiday gifts you received; second, apart from the emotional value of the items, if you did not have them, how much would you be willing to pay to get them? His results were unpleasant: on average, a gift was valued by the receiver well below the price paid by the giver.
The most conservative(保守的) estimate put the average receiver’s valuation at 90% of the buying price. The missing 10% is what economists call a deadweight loss; a waste of resources that could be avoided without making anyone poorer. In other words, if the giver gave the cash value of the purchase instead of the gift itself, the receiver could then buy what she really wants and be better off for no extra cost. It suggests that in America, where givers spend $40 billion on Christmas gifts, $ 4 billion is being lost annually in the process of gift giving. Add in birthdays, weddings and non Christian occasions, and the figure would balloon. So should economists call for an end to gift giving, or at least press for money to become the gift of choice?
56. Why do some people regard the holiday season in western economies a treat?
A. Because the economic situation in US has been depressing.
B. Because American sellers make a quarter of their yearly sales through holiday season.
C. Because holiday spending can speed up GDP growth.
D. Because sellers can make as much profit as 60 % over holiday season.
57. What's the main idea for the second paragraph?
A. In many cases the gifts cannot meet the receivers’ needs.
B. The purchases made over holiday season are actually a waste of money.
C. It's really not easy to guess the others’ preferences.
D. Much of the holiday spending is on gifts for others.

A. prove the mismatch between wants and gifts
B. estimate the disparity between wants and gifts in economic terms
C. spark new ideas of economic studies on holiday spending
D. discover the exact cost of holiday spending on gift giving
59. Economists think of the misusing 10% of holiday spending as a deadweight loss because
_______.
A. the cash value of the purchase is lower than the buying price
B. it is actually a waste of resources in economic terms
C. with the money the receivers can be better off for no extra cost
D. it makes many people even poorer for spending more on unwanted gifts
60. According to the passage altogether how much money is wasted every year on gift giving?
A. About $4 billion. B. About 10% of the total value.
C. About $40 billion. D. Much more than $4 billion.

Decisions, decisions! Our lives are full of them, from the small ones to the life-changing. The right to choose is central to everyone. Yet sometimes we make bad decisions that leave us unhappy or full of regret. Can science help?
Most of us know little about the mental processes that lie behind our decisions. Luckily, what psychologists are finding may help us all make better choices. Here are some of their amazing discoveries to help you make up your mind.
Consider your emotions. You might think that emotions are the enemy of decision-making, but in fact they are a part of it. Whenever you make up your mind, your brain’s emotional centre is active. University of Southern California scientist, Antonio Damasia, has studied people with damage to only the emotional parts of their brains, and found that they were unable to make basic choices about what to wear or eat. Damasia thinks this may be because our brains store emotional memories of past choice, which we use to help the present decision-making.
However, making choices under the influence of an emotion can greatly affect the result. Take anger for example. A study by Nitika Garg of the University of Mississippi and other scientists found the angry shoppers were more likely to choose the first thing they were offered rather than considering other choices. It seems that anger can lead us to make quick decisions without much thinking.
All emotions affect our thinking and motivation，so it may be best to avoid making important decisions under their influence. Yet strangely there is one emotion that seems to help us make good choices. The American researchers found that sad people took time to consider the various choices on offer, and ended up making the best choices. In fact many studies show that people who feel unhappy have the most reasonable view of the world.
1. What does the underlined word “central” mean?
A. in the middle B. easy to reach C. important D. having power
2. Damasia’s study suggests that ________.
A. emotions are the enemy of decision-making.
B. our brain has nothing to do with decision-making.
C. people with physical damage find it hard to make up their minds.
D. our emotional memories of past choices can affect present decisions.
3. According to the text, what may help us make better decisions?
A. To think about happy times.
B. To make many decisions at a time.
C. To stop feeling regretful about the past.
D. To learn about the process of decision-making.
4. Why are angry shoppers more likely to choose the first thing they are offered?
A. They often forget their past choices. B. They make decisions without much thinking.
C. They tend to save time when shopping. D. They are too angry to bargain.
5. What do we learn from the text?
A. Emotions are a part of decision-making.
B. Sad people always make worse choices.
C. No emotion seems to help us make good choices.
D. Only sad feelings affect our thinking and motivation.

As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.
When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.
There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.
1. The author says that the world population is increasing because _____.
A. there are many rich valleys and large fields
B. farmers are producing more crops than before
C. people are living longer due to better living conditions
D. new lands are being made into farmlands
2. The author says that in areas with large populations, land might be more productively farmed if _____.
A. the land was divided into smaller pieces
B. people moved into the countryside
C. industrial methods were used in farming
D. the units of land were much larger
3. We are told that there are now farms beyond the Arctic Circle. This has been made possible by _____.
A. growing new types of crops
B. irrigation and dry-farming means
C. providing fertilizers
D. destroying pests and diseases
4. Why is the land divided into tiny units in some areas?
A. There are too many people living there.
B. It saves more natural resources there.
C. It prevents crops from serious diseases there.
D. Farmers can grow various kinds of crops there.
5. Why do some people use dams to hold back waters from great rivers?
A. To develop a new kind of dry-farming methods.
B. To prevent crops from floods.
C. To provide water and electricity in all seasons.
D. To water poor lands in bad weather.

Most shops in Britain open at 9:00 am, and close at 5:00 or 5:30 in the evening. Small shops usually close for an hour at lunchtime. On one or two days a week—usually Thursday and/or Friday—some large food shops stay open until about 8:00 pm for late night shopping.
Many shops are closed in the afternoon on one day a week. The day is usually Wednesday or Thursday and it is a different day in different towns.
Nearly all shops are closed on Sundays. Newspaper shops are open in the morning, and sell sweets and cigarettes as well. But not all the things can be sold on Sundays.
Usually it is not difficult for foreign visitors to find where to buy things. Most shops sell the things that you want to buy. One problem is stamps. In Britain you can only buy these at post offices. Many large food shops are self-service. When you go into one of these shops, you take a basket and you put the things you wish to buy into this. You pay for everything just before you leave. If anyone tries to take things from a shop without paying they are almost certain to be caught, because most shops have detectives.
When you are waiting to be served in a shop, it is important not try to be served before people who arrive before you. Many foreign people are surprised at the British way of queuing (排队).
