For example, North Americans tend to expect more
physical distance between two speakers than do Latin Americans. Consequently, when the Latin American seems to be leaning too close, the North American complains of "invasion of his space. " The Latin American,24-A. Savingthe Rainforests for Future Generations
Rainforests are being cut and burned from Brazil to Indonesia at such a rate that they could well disappear from the earth's surface before the year 2050. They are being cleared for
valuabletimber and other resources to speed up the economic growth of the nations in which they are located. The most recent figures show that the area of rainforest destroyed last year alone was bigger than the size of Great Britain and Ireland.If the present rate of deforestation is allowed to continue, the consequences for the earth will be great. We shall see a
massive upsetting of eco
systems, very large increases in soil erosion, increases in flooding and in
drought, changes in
rainfall patterns and regional, quite possibly global, changes in
climate. We shall also probably lose many rare plant and animal
species.
According to many scientists, the burning of rainforests is also directly contributing to the
so-calledgreenhouse effect. This effect, they say, is raising average temperatures and sea levels as the polar ice caps recede.The rainforest is
essential in other areas also. It is a medicine chest of
unlimitedpotential. The US National Cancer Institute has identified 2,000 rainforest plants which could be
beneficial in fighting
cancer. In today's pharmaceutical market, 15 of the 125 drugs derived from plants were discovered in the rainforest.
Plant
species are not the only forms of life threatened with extinction in the rainforest. Rare birds and animals that cannot be found
anywhere else in the world have been disappearing at the rate of one a year since the turn of the century.In the face of all these facts, it seems
senseless for countries to continue destroying their rainforests. However, the problem is not so simple. The countries in which the rainforests are located are all quite poor and overpopulated. One of them, Brazil, has a population of 140 million, about half of whom are living in
absolutepoverty. The governments in these countries are usually also too weak to stop large companies and powerful individuals from destroying the rainforests. They have no money, so when the poor whom they cannot feed find work cutting down trees or burning forestland, the governments often have no choice but to turn a blind eye. Moreover, for many of these countries, the
valuabletimber and other resources found in the rainforests are also a very important source of foreign exchange, which they badly need to pay off their foreign debts and purchase foreign
equipment and other goods.
The only
solution to the problem, then, seems to be for the richer countries of the world to help the countries where the rainforests are located. One way they could help would be by cancelling the
international debts that countries like Brazil owe, while also
working together with these countries to solve their other economic problems. At the same time, they could support programmes to teach the local people to regard the rainforests as gardens to be
harvested, and not merely as places where the only way for them to make a living is by
senselessly cutting down trees and burning.Such prpgrammes could teach the local people how to select trees worth exporting and to cut only those trees down while leaving the rest, so that the basic
make-up of the forest would not be disturbed. This would also mean that the
environment needed for the survival of the many rare
species of animals and plants, as well as of the Indian tribes that live in the rainforest, could be preserved. The local people could also be taught to earn more money by cutting the selected trees and making them into furniture on the spot. In
addition, they could learn how to
harvest other
valuable natural materials that are now being wasted, and sell them
overseas to earn foreign exchange for their countries.
Last but not least, people in the richer countries of the world could also help save the rainforests by using wood-derived products such as paper more carefully and by recycling used paper products to help reduce the demand for newly cut wood.24-B. Life on the Tundra
Tundra is the name given to the low, marshy plains of Europe, Siberia, and North America that border on the Arctic Ocean. In Alaska, the vast, cold region known as the "Northern Slope" is part of the tundra. Nature sets harsh terms for survival in this land. Only those plants and animals that are adapted to the
hostileenvironment can
survive in it.Long periods of darkness and bitter cold are the major threats to life on the tundra. At the Arctic Circle, the sun cannot be seen above the
horizon in December. North of the Circle, the darkness lasts even longer. Over the northern reaches of the tundra, no
sunlight can be seen at all for several months of the year.
The darkness is balanced, to some degree, by
continuousdaylight during the summer months. But even in the warmest month, the temperature only averages about 50 degrees F (10 degrees C). During the dark winter months the average temperature falls to - 16 degrees F ( -27 degrees C), and sometimes to ?40 degrees (C and F) and below.Because of the
intense cold, the subsoil of the tundra remains
permanentlyfrozen to a great depth. During the brief summer, a few feet (about a meter) of soil thaw at the surface. It is this thin layer of active soil that supports all living things on the tundra.
For nine months of the year, the tundra is a dark,
seeminglylifeless wild land. Then in June, as if by magic, a never-setting summer sun gives birth to hundreds of
species of
arctic plants to cover the ground.A plant that grows more than three feet (about a meter) is
unusual on the tundra. There are no tall trees. The
frozen subsoil prevents roots from growing deep enough to support them. By the end of August the
breath of winter returns, and by mid-September the tundra is White again.
The animal life on the tundra is
unusually rich for an
environment that seems so harsh. Herds of
arctic deer move from place to place in search of food. Bands of wolves follow them and hunt for the weak or sick ones.Few birds
actually live on the tundra. However, a
variety of birds
migrate to nest and feed during the summer. The wet, marshy lance produces a large number of insects that provide food for the smaller birds that, in turn, provide food for the
arctic fox and the wolf.
The balance of nature is so
delicate on the tundra that even minor disturbances may produce major changes in the
environment. Any in-crease or
decrease in the population of one
species may
affect all other
species on the tundra. For example, if the number of wolves and foxes
decreases, the food chain is upset. Without wolves, the number of grazing animals - like the deer - would increase. This increase would result in a food
shortage, which would cause death to many smaller animals. A
decrease in the number of these srnaller animals would in turn
decrease the food supply for the
arctic fox and the wolf. In this way, the entire food chain might be
affected by a change in the number of a single
species.Until recently, the c
hanging seasons on the tundra were seen only by a few Eskimo hunters and explorers. What would draw men and women to live in such a
hostile land? The answer is oil.
In 1968, oil was discovered beneath the
frozen soil on Alaska's Northern Slope. Now an 800-mile (about 1300 kilometers) pipeline has been built from Prudhoe Bay on the Arctic Ocean to Valdes, a port on the south coast of Alaska. The pipeline carries the oil from the Northern Slope, across the tundra, to the port. From there, it is shipped to the rest of the United States.Thousands of men and women were needed to build and
maintain the pipeline. For the first time, large numbers of people were brought into
contact with the tundra. Their presence and the presence of the pipeline they built represented a major change in the
environment. How will the life cycles of the tundra be
affected?
The survival of the United States depends on the
ability to find new sources of
energy. Oil from beneath the tundra is very important to the nations' development. But the survival of the tundra depends on how carefully people
maintain the
delicate balance of nature in this
environment.25-A. American Men Don't Cry
American men don't cry because it is considered not
characteristic of men to do so. Only women cry. Cry is a "
weakness"
characteristic of the
female, and no American male wants to be identified with any-thing in the least weak or
feminine. Crying, in our
culture, is identified with childishness, with
weakness and
dependence. No one likes a crybaby, and we
disapprove of crying even in children, discouraging it in them as early as possible. In a land so
devoted to the
pursuit of happiness as ours, crying really is rather un-American. Adults must learn not to cry in situations in which it is permissible for a child to cry. Women being the "weaker" and "dependent" sex, it is only natural that they should cry in certain
emotional situations. In women, crying is excusable. But in men, crying is a mark of
weakness. So goes the American
belief with regard to crying."A little man," we
impress on our male children, "never cries. Only girls and crybabies do." And so we condition males in America not to cry
whenever they feel like doing so. It is not that American males are
unable to cry because of some
logical" target="_blank" title="a.生物学(上)的">
biological time clock within them which causes them to run down in that
capacity as they grow older, but that they are trained not to cry. And so the "little man" controls his desire to cry and goes on doing so until he is
unable to cry even when he wants to. Thus do we produce a trained in
capacity in the American male to cry. And this is bad. Why is it bad? Because crying is a natural
function of the human
organism which is designed to
restore the
emotionally disequilibrated person to a state of
equilibrium. The return of the disequilibrated organ
systems of the body to steady states or dynamic st
ability is known as homeostasis. Crying serves a homeostatic
function for the
organism as a whole. Any
interference with homeostasis is likely to be damaging to the
organism. And there is good reason to believe that the American male抯 trained in
capacity to cry is
seriously damaging to him.
It is unnecessary to cry
whenever one wants to cry, but one should he able to cry when one ought to cry - when one needs to cry. For to cry under certain
emotionally disequilibrating conditions is necessary for the
maintenance of health.To be human is to weep. The human
species is the only one in the whole of
animated nature that sheds tears. The trained in
ability of any human being to weep is a lessening of his
capacity to be human - a
defect which usually goes deeper than the mere in
ability to cry. And this, among other things, is what American parents - with the best intentions in the world - have achieved for the American male. It is very sad. If we feel like it, let us all have a good cry - and clear our minds of those cobwebs of
confusion which have for so long prevented us from under
standing the natural necessity of crying.
25-B. Stop Worrying Now !Worry is one of the most common forms of
emotionaldistress in our
culture. Almost
everyone spends a
considerableamount of present moments worrying about the future. And
virtually all of it is for nothing. Obsessive worry will never make things any better. In fact, such worry will very likely help you to be less
effective in
dealing with the present.
In order to reduce worry, it is necessary to understand the subconscious
logical" target="_blank" title="a.心理学(上)的">
psychological "payoffs" for choosing to worry in the first place. "I can't do a thing. I'm too worried about..." This is a common
lament, and one with a payoff that keeps you
standing still and avoiding the risk of action. Clearly, it is easier, if less
rewarding, to worry than to be an active, involved person.By worrying about someone else, you can label yourself as a caring person. Worry proves that you are a good parent or
spouse ("I can't help worrying - its because I love you."). A handsome
dividend, although
lacking in
logical,
healthy thinking.
If you weigh too much, you may eat more when you worry; hence, you have a good reason for
hanging on to the worry
behavior. Similarly, you may find yourself smoking more in troublesome situations, and can use the worry to avoid giving up smoking. The same neurotic
rewardsystem also applies to health. It may be easier for you to worry about chest pains than to risk
finding out the truth, and then having to deal directly with yourself.Worry can bring a lot of diseases such as
tension headaches and backaches. While these may not seem to be payoffs, they do result in
considerable attention from others and justify much self-pity as well. And some people would rather be pitied than fulfilled.
Now that you understand the
logical" target="_blank" title="a.心理学(上)的">
psychological support
system for neurotic worry, you can begin to
devise some measures for reducing the number of troublesome worry bugs that breed in this
erroneous zone.Begin to view your present moments as times to live, rather than times to worry about the future. When you catch yourself worrying, ask yourself, "What am I avoiding now by using up this moment with worry?" Then begin to attack
whatever it is you're avoiding.
A friend of mine spent a week on an island off the Connecticut coast. She enjoys
taking long walks, but soon discovered that there were a number of dogs on the island which were allowed to run free. She
decided to fight her worry that they might attack her. She carried a rock in her hand and
resolved to show no fear as the dogs came
running toward her. Seeing someone who refused to back down, they turned and ran away. While I am not encouraging dangerous
behavior, I do believe that a sensibly
effectivechallenge to worry is the most
productive way to
minimize its role in your life.Ask yourself over and over, "Will the future change as a result of my worrying about it?" Try to remember how many of the things you once worried about never become real at all. Also ask yourself; "What's the worst thing that could happen to me (or them), and what is the
likelihood of it occurring?" You'll discover the
absurdity of most worries in this way.
Act in direct
conflict with your usual areas of worry. If you compulsively save for the future, use some money for your own
enjoyment today. Enjoy life; don't waste the present with immobilizing thoughts about the future.These are some techniques for minimizing worry in your life. But the most
effectiveweapon you have is your own
determination to drive this neurotic
behavior away from your life.
