Man and Nature
The balance of nature is a delicate system of checks and counterchecks. Nature has its own way of checking the life and distribution of the different organisms and helping their growth. An epidemic may be considered nature's way of checking population growth. Man in his attempt to conquer nature and to utilize it to his advantage has interfered with the balance of nature, thereby creating problems of a complex nature. Nature's ways of maintaining the balance are intricate and not easily understood and man's application of his scientific knowledge and techniques has upset this balance so much that today, being aware of the disastrous consequences, he takes measures against them.
No animal or plant can live in isolation, for different organisms are parts of a vast dynamic complex of living things. As no man or community is self-sufficient, no organism can live by itself. When man interferes with the interdependence and interrelationships of the different organisms, he is, in effect, upsetting their balanced relationships and his action can have a chain reaction. If we prevent fish eggs from being deposited in a pond, we are allowing an unchecked growth of weeds. The waterfowl which feeds on tadpoles will look for alternatives, thereby tending to upset these balanced relationships. It is important that for the preservation of beauty in nature the balance of nature is maintained.
Man for his own survival has to make his peace with plant and animal life, the size and distribution of which he has interfered with. It is to be noted that in every plant and animal community there is a trend towards a balance between the different species. When each successive species is of the right number to maintain a constant population, a balance between the different species is maintained and this state is referred to as the climax stage. Man is forever upsetting the balance of the climax stage. He has added to the numbers of animals and plants that are useful to him. In the process he has unwittingly helped the increase in the number of insects and vermin and as a result he has to wage a relentless war against them. If man continues to interfere with the balance of nature, it is possible that some animals and birds may soon become extinct. The indiscriminate hunting of whales has reduced the number of some species almost to the verge of extinction and international laws have been drawn up to protect them.
The balance of nature is to be maintained in order to prevent soil deterioration. Human intervention has altered the established relationship between the plants of an area and the soil of that area. Animals introduced by man, sheep and goats for example, have led to widespread soil deterioration. By cutting down trees or by practising unsuitable systems of agriculture, man destroys the crumb structure of soil, thereby making it susceptible to erosion. Soil erosion results in loss of soil fertility and maintaining soil fertility is considered the biggest problem facing mankind apart from the prevention of war. The increase in world population and the growth of civilisation have been the two major factors that have led man to cut down forests on an unprecedented scale and the erosion caused by the cutting down of huge areas of forests has resulted in floods on a scale hitherto unknown. Soil erosion can whittle away soil fertility and if adequate and effective measures are not taken it can become a menacing spectre tearing at the prosperity of many countries.
Pollution, in its different forms, interferes with the balance of nature. Water pollution affects nature's balance in oceans, lakes and rivers. Man-made pollution of water is due to, municipal sewage, dumping by factories and the depositing of pesticides. Solid wastes can permeate the soil and pollute lakes and rivers.
Man has to adopt the philosophy of thrift by conserving natural resource

听力原文： For those of us lucky enough to always have enough food and water, it may be hard to imagine living through a drought. A drought occurs for a variety of reasons, usually including a lack of rainfall and high temperatures. Soil moisture severely dwindles. Why and how do these meteorological events occur？
As air swirls around the earth, it rises and sinks over different areas of the globe. When air rises it cools and loses moisture. When air sinks, it grows warmer and absorbs moisture, drying out the land. Sinking air helps to form. deserts, such as the Sahara Desert in Africa.
Warm, sinking air can hamper cloud formation, which results in less rain and lower overall humidity. When these conditions occur in an area that normally receives enough rain to allow plants to grow and keep water sources replenished, a drought can ensue. The Dust Bowl that affected the prairie regions of the United States was one infamous drought. An equally severe drought occurred in the United States in the summer of 1988. Rainfall o-ver the mid-west, Northern Plains, and the Rockies was fifty to eighty-five percent below normal.
Sometimes over-farming and soil erosion contribute to drought, but there are also natural disasters that can occur when soil is carefully preserved. When a drought hits, there's little that can be done to end it. Water and soil conservation can help, but until the rains come again there's not much science can do.
Questions:
14. According to the passage, which results in less rain and lower overall humidity？
15. Which of the following can hamper cloud formation and lead to less rain and lower overall humidity？
16. What can contribute to drought？
(14)
A．cools
B．air rises
C．deserts
D．warm

听力原文： Everyone knows about unemployment. But millions of working Americans are now facing a less familiar and perhaps more troubling problem: shrinking wages. It's a phenomenon that takes many forms. Some workers have had to swallow outright pay cuts. Others have lost their jobs and, in the tough labor market of today, have had to settle for new ones at less pay. Still others—including employees at such giants as AT&T, Boise Cascade and Starwood Hotels—have had to accept pay freezes that, when rising prices are factored in, amount to reduced compensation. To add insult to injury, companies everywhere are reducing bonuses and overtime and eroding health and pension benefits.
The numbers are grim. For the 500,000 workers laid off since January, the average job search has stretched to a 19-year high of nearly five months—about twice the duration of the typical severance package. According to outplacement firm Challenger, Gray & Christmas, 17% of those who do find work—nearly double the historical percentage—are settling for less pay. The net result of the various pressures on pay is in the first three months of 2003, median weekly earnings adjusted for inflation fell 1.5%, according to the U.S. Labor Department. That's the biggest drop since 1991, according to Jared Bernstein, an economist at the Economic Policy Institute, a research group based in Washington. Wage erosion partly explains why the Federal Reserve Board openly frets about the threat of deflation, a downward spiral in prices that can cripple an economy by making debt repayment more difficult and encouraging consumers to wait for even lower prices. Adding fuel to the deflation debate, the cost of goods to both consumers and manufacturers fell in April, officials reported last week.
Which of the following is NOT a form. of wage erosion？
A．Pay cuts.
B．Pay freezes.
C．Bonus reduction.
D．Job-hopping.
