单选题 Damp conditions favor the growth of moulds and bacteria. If food is kept dry, these organisms cannot spoil it. You probably know how soon fresh vegetables begin to 'sweat' and rot and, by comparison, how long dried peas will keep if stored in a screw-top jar. Refrigeration is another way of preserving food. Deep-frozen meat and vegetables will keep for months. Though few bacteria are killed by freezing, bacterial growth is either prevented or greatly retarded. The presence of a lot of sugar in food is another way of preserving it. Jam and sweetened condensed milk are examples. Dried fruit also has a high concentration of sugar. Neither fungi nor bacteria will grow in such a medium. Meat and fish are sometimes salted for the same reason. Canned food forms a significant proportion of the diet of many families. Food is heated in the can at a high temperature, under pressure. Heating in this way destroys all bacteria and fungi. As long as the can remains sealed the food in it will last indefinitely. Recently some food canned at the time of the Napoleonic Wars (1805—1815) was opened for testing and found to be uncontaminated (未污染的). Milk is partially preserved by pasteurization. In this process the milk is kept at 65℃ for 30 minutes and then chilled. Heating to this temperature destroys some kinds of bacteria, including the one that causes tuberculosis. It does not kill many of the harmless varieties of bacteria, and some of these will cause the milk to turn sour if it is not kept chilled.

单选题Because agriculture is so important to a nation's well-being, governments have always been concerned with it. For example, the United States and Canada have long produced surpluses that complicate their economies. Surpluses tend to lower prices to farmers and seriously endanger the agriculture industry. Governments have instituted systems of price supports to maintain a fair price when surpluses cause prices to drop. The system in the United States is a good example. A government program supports the prices paid to farmers for grains, and other agricultural products. Support prices are based on parity, which is the ratio between the prices farmers receive for their crops and the prices they must pay for things they need. The government selected the period from 1910 to 1914 as a time when farm prices were in a fair ratio with farming costs. This is the base period now used to determine parity prices. The idea is to assure farmers that what they get for a bushel of wheat will buy the same amount of, say, seed as it did in the years of the base period; if prices drop too far below this ideal the government can help in a number of ways. For example, it may buy much of a surplus at parity prices. Governments have instituted a wide variety of other controls for prices and, also, for farm output, mainly at the request of the farmers themselves. Farm prices tend to fluctuate more than other prices do, and the incomes of farmers fluctuate along with farm prices. Various measures for maintaining farm prices and incomes include tariff or import levies, import quotas, export subsidies, direct payment to farmers, and limitations on production. All of these measures are useful and are used to some extent by most developed countries. An important example of such a program is the soil-bank plan, which aimed at limiting production while improving farmland. The European Economic Community (EEC) established a common agricultural policy (CAP) for its member nations, called the Common Market countries. The aim is to create free trade for individual commodities within the community. When production of a commodity exceeds EEC consumption, the EEC may buy the excess for storage, pay to have it reprocessed, or export it to countries outside the Common Market. In this way the EEC can maintain its members' farm prices at levels equal to or even higher than those in such market-competitive nations as the United States and Canada.

单选题 After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly. This stage of sleep is called REM, which stands for rapid eye movement. If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!
