听力原文： Many families in the United States have a larger income than ever before, but people are finding it difficult to make ends meet anyway. Almost everyone is wondering, "What happens to all my money？ I never seem to have anything left to put away."
Why isn't a dollar worth as much as it used to be？ One dollar is always worth the same amount, that is, 100 cents. But the value of a dollar is how much it can buy. The value of money depends on the cost of living. Economists say that the cost of living is the money that a family must pay for the necessities of life such as food, housing or rent, clothes, and medical expenses. For many years now, the cost of living has increased greatly, so the value of the dollar has decreased. When a dollar has a low value, you can't buy as many things with it.
No one fully understands why the cost of living keeps increasing, but economists believe that workers and producers can make the prices go up. As workers earn more money, they have more money to spend, so they demand more goods. If there is a great demand for certain goods, the prices of these goods go up. At the same time, if there's shortage of goods, the prices also go up. For example, if everyone wants to buy more and more gas, the price of gas goes up. When companies withhold gas from buyers, they can also make the price of gas go up.
Families need to know what happens to their money. They need to make their income meet the cost of living. So many people plan a family budget. A budget is a list of monthly expenses. If your expenses add up to more than your income, you must find ways to save money. Maybe you're spending too much on entertainment. Or if you're spending too much on clothes, you may want to sew your own clothes. Budgeting helps you spend your money wisely as the cost of living increases.

A．A larger income often results in a lower living standard.
B．No more money is left over in spite of a larger income.
C．To put away some money has become a necessity.
D．They don't know where their money has gone.

The Central Problem of Economics
The central problem of economics is to satisfy the people's and nation's wants.
The problem we are faced with is that our resources, here identified as money, are limited. The only way we can resolve our problem is to make choices. After looking at our resources, we must examine our list of (19)______ and identify the things we need immediately, those we can postpone, and (20)______ we cannot afford. As individuals, we face the central problem involved in economics deciding just how to allocate (分配) our limited resources to provide (21)______ with the greatest satisfaction of our wants. Nations face the same problem. As a country's population grows the need for more goods and services grows correspondingly. Resources necessary to production may increase, but there (22)______ are enough re sources to satisfy the total desires of a nation. Whether the budget meeting is taking place in the family (23)______ room, in the conference room of the corporation (24)______ of directors, or in the chamber of the House of Representatives in Washington, the basic problem still exists. We need to find methods of allocating limited resources in order to satisfy unlimited wants.
A short time ago economists (25)______ goods into two categories, free and economic. The former, like air and water, were in (26)______ abundance that economists had no concern for them. After all, economics is the (27)______ of scarcity (匮乏) and what to do about it. Today many of these "free goods" are (28)______ very expensive to use.

Part B
Read the following material and write a short essay of about 150 words under the title "Should Men Be Forced by Law to Do Half the Housework？"
The Austrian parliament will shortly be considering a draft law designed to compensate women after a divorce if their former husbands never helped them with the housework.
Last week the German Green Party went even further, demanding a new law to make couples share the chores fifty-fifty if both partners were at work. The German paper Bild said a third of German women did all the housework on their own.
Academics here in Britain talked of reversing what they called the "Allerednic effect" — that's "Cinderella" backwards—in which a prince marries a princess and turns her into a scullery-maid.
So is it time for men to clean up their act？ Or should the lawmakers leave it all well alone？
Joining Laurence Zavriew for the Europewide debate are from Rome the Italian journalist Carlo di Blasio, and in the Netherlands Kerstin Schweighoefer, correspondent of the German newsmagazine focus.

Lately, economists have added up the actual costs. The Environmental Protection Agency estimates that salt-induced road damage and vehicle corrosion cost $ 3 billion a year. That does not include damage to underground cables, which adds hundreds of millions to utility bills. Nor does it reflect the cost of brine leaking into porous water pipes, threatening the water supply. Salty water leaches into roadbeds, kills evergreens and poisons streams.
The various costs probably add another $ 2 billion to the national salt bill. Scientists estimate the full economic, or "life cycle," cost for a ton of salt at $ 500, or 20 times the $ 25 purchase price. That begins to make the switch to calcium magnesium acetate, perhaps the most promising alternative look practical. CMA, made from acetic acid and dolomitic(含白石的) lime, costs $ 600 a ton and has minimal adverse effect. Some researchers believe the cost can be halved by making CMA from waste cheese whey or pulp-mill effluent.
While CMA and other alternatives are being researched, many cities and states are cutting back on their use of salt. Keeping dispensing equipment in good repair helps reduce the amount spread.
Salt spread on road in winter may cause all the following problems except ______.
A．road damage
B．vehicle corrosion
C．damage of underground cables
D．car accident
第9题
Women's education may be unusual territory for economists, but enhancing women's contribution to development is actually as much an economic as a social issue. And economics, with its emphasis on incentives (激励), provides guideposts that point to an explanation for why so many girls are deprived of an education.
Parents in low-income countries fail to invest in their daughters because they do not expect them to make an economic contribution to the family: girls grow up only to marry into somebody else's family and bear children. Girls are thus seen as less valuable than boys and art kept at home to do housework while their brothers are sent to school the prophecy (预言)becomes self-fulfilling, trapping women in a vicious circle (恶性循环) of neglect.
An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children, ensuring that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys, will be educated and healthy. The vicious circle is thus transformed into a virtuous circle.
Few will dispute that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously, there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 per cent for each additional year of schooling. Such big returns are impressive by the standard of other available investments, but they are just the beginning. Educating women also has a significant impact on health practices, including family planning.
The author argues that educating girls in developing countries is ______.
A．troublesome
B．labor-saving
C．rewarding
D．expensive
