Human beings use a little less than half the water available worldwide. Yet shortages and droughts (干旱)
are causing starvation and poverty in some areas, and industrial and agricultural by-products are polluting water
supplies. Since the world"s population is expected to double in the next 51 years, many experts think we are on
the edge of a widespread water crisis.
But that doesn"t have to be the result. Water shortages do not have to trouble the world-if we start valuing
water more than we have in the past. Just as we began to value petrol more after the 1970s oil crisis, today we must start looking at water from a fresh economic view. We can no longer afford to consider water a nearly
free resource of which we can use as much as we like in any way we want.
Instead, for all uses except the demand of the poor, governments should price water to reflect its real value. This means charging a fee for the water itself as well as for the supply costs.
Governments should also protect this source by providing water in more economically and environmentally
sound ways. For example, often the cheapest way to provide irrigation (灌溉) water in the dry places is through small-scale projects, such as gathering rainfall in depressions(凹地) and pumping it to nearby cropland.
No matter what steps governments take to provide water more efficiently, they must change their ways to
use water. Rather than control hundreds or even thousands of local, regional agencies that watch water use,
countries should set up central authorities to manage water policy.
B. The world population is increasing faster and faster.
C. Half of the world"s resources have been seriously polluted.
D. Human beings have not placed sufficient value on water resources.
B. has been exaggerated by some experts in the field
C. poses a challenge to the technology of building reservoirs
D. is underestimated by government organizations at different levels
B. stimulate domestic demand
C. equal its real value
D. take into account the occurrences of droughts.

seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body.
They have found that laughter really can improve people"s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while
doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar
effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people
breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter
exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one
experiment doctors produced pain in groups of students who listened to different radio programmes. The
group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny programme.
The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain
which diminishes both stress and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they
help to improve their patients"condition by encouraging them to laugh. They have found that even if their
patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to
those caused by laughter.
B. laughter can be tolerated
C. there is a way to reduce pain
D. laughter can work the muscles in the feet
B. smile can produce the same effects as laughter

B. stop
C. reduce
D. increase
B. in order to improve patients" health

of the nation and international cooperation. Individually, it can enlarge our personal perspective and knowledge,

However, tourism can also lead to pollution and the destruction of places of interest, which is difficult to
avoid.
Fortunately, "Green Tourism" is now being promoted and developed all over the world. As time goes by,
people will begin to realize the importance of these places of interest. "Green Tourism" teaches people to love
nature more and to consciously protect it by enjoying its beautiful scenery and learning more about it. "Green
Tourism" is the best kind of tourism as its purpose is to appreciate and research natural environments including
wild plants and animals, and of course the cultures of many places.
Compared with traditional tourism, the main characteristic (特色) of "Green Tourism" is learning more
about nature and people. Traditionally, people travel the world to amuse themselves and pass time pleasantly.
But "Green Tourists" are different. They travel because they are attracted by the characteristics of protected
areas. They want to make good use of natural resources but not use them up. For example, they research the
wildlife, the culture and the customs or a place so that they can learn more about the history and value of the
area.
In short, "Green Tourism" has a purpose and a plan, but not to pollute or destroy our places of interest.

Then consider this, you might be in a state of sub-health (亚健康).
Sub-health, also called the third state or grey state, is explained as an indefinite (不确定的) state between
health and disease. According to an investigation by the National Health Organization, over 45 percent of sub-
health people are middle-aged or elderly. The percentage is even higher among people who work in management
position as well as students around exams.
Symptoms (症状) include a lack of energy, depression, slow reaction, insomnia, worries and poor memory.
Other symptoms include shortness of breath, sweating and aching on the waist and legs.
The key to preventing and recovering from sub-health, according to some medical experts, is to form good
living habits, alternate (交替) work with rest, exercise regularly, and take part in open air activities.
As for meals, people are advised to eat less salt and sugar. They should eat more fresh vegetables, fruits and
fish, because they are rich in nutritional elements-vitamins and tiny elements-those are important to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy
changes in the digestive tract. They also say that a balanced diet is _____.

as they must today. They did not need to worry a lot about the safety of the new products that they developed.
They did not have to pay much attention to the health and safety of the people who worked for them. Often
new products were dangerous for the people who used them; often conditions in the work place had very bad
effects on the health of the workers.
Of course sometimes there were real disasters which attracted the attention of governments and which
showed the need for changes. Also scientists who were doing research into the health of workers sometimes
produced information that governments could not ignore. At such times, there were inquiries into the causes
of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however,
the new rules came too late to protect the people who died or who became seriously ill.
Today many governments have special departments that protect customers and workers. In the U.S., for
example, there is a department that tests new airplanes and gives warnings about possible problems. It also
makes the rules that aircraft producers must follow. Another department controls the foods and drugs that
companies sell. A third department looks at the places where people work, and then reports any companies that
are breaking the laws which protect the health and safety of workers. Of course, new government departments
and new laws cannot prevent every accident or illness, but they are having some good results. Our work places
are safer and cleaner than before. The planes and cars that we use for travel are better. Producers are thinking
more about the safety and health of the people who buy and use their products.
B. companies were free to put out any products they wanted to
C. many people were killed by dangerous products
D. industries were as careful in management as they are today
B. scientists also helped improve the safety and health of workers and customers
C. government officials often did not listen to scientists
D. governments paid no attention to the safety of products at all
B. came into being as a result of the workers" demands
C. were introduced because quite a number of people were killed or seriously injured
D. were effective enough to protect workers and customers
B. designing new products
C. controlling the sale of products
D. inspecting work places
