Natural Medicines

Since earliest days,humans have used some kinds of medicines.We know this because humans have
survived.Ancient treatments for injury and disease were successful enough to keep humans from dying out
completely.
They were successful long before the time of modern medicine.Before the time of doctors with white
coats and shiny（发亮的）instruments. Before the time of big hospitals with strange and wonderful equipment.
Many parts of the world still do not have university-educated doctors. Nor do they have expensive hospi-
tals.Yet injuries are treated.And diseases are often cured.How?By ancient methods.By medicines that
might seem mysterious , even magical（有魔力的）.Traditional medicines are neither mysterious nor magical,
however.
Through the centuries, tribal（部族的）medicine men experimented with plants. They found many use-
ful chemicals in the plants.And scientists believe many of these traditional medicines may provide the cure
for some of today's most serious diseases.
Experts say almost 80% of the people in the world use plants for health care.These natural medicines
are used not just because people have no other form of treatment.They are used because people trust them.
In developed areas,few people think about the source of the medicines they buy in a store.Yet many wide-
ly-used medicines are from ancient sources,especially plants.Some experts say more than 25% of modern
medicines come,in one way or another,from nature.
Scientists have long known that nature is really a chemical factory.All living things contain chemicals
that help them survive.So scientists' interest in traditional medicine is not new.But it has become an ur-
gent concern.This is because the earth's supply of natural medicines may be dropping rapidly.

What do the majority of the people in the world use for health care?
A:Strange and wonderful equipment.
B:Factory-produced chemicals.
C:Modern medicines.
D:Plants.

资料： The poverty line is the minimum income that people need for an acceptable standard of living. People with incomes below the poverty line are considered poor. Economists study the causes of poverty in order to find solutions to the problem.
As the general standard of living in the country rises, the poverty line does, too. Therefore, even with today’s relatively high standard of living, about 10 percent of the people in the United States are below the poverty line. However, if these people had stable jobs, they could have an acceptable standard of living. Economists suggest several reasons why poor people do not have jobs.
For one thing, more than half of the poor people in the United States are not qualified to work. Over 40 percent of the poor. People are children. By law, children less than 16 years old cannot work in many industries. A large number of poor people are Old. Many companies do not hire people over 65 years old, the normal retirement age.
Some poor adults do not look for jobs for a variety of personal reasons: they are sick, they do not have any motivation, they have family problems, or they do not believe that they can find a job.
Other poor people look for a job but cannot find one. Many poor adults never went to high school. Therefore, when they look for jobs, they have few skills that they can offer.
At the present time, the government thinks it can reduce poverty in the country in the following ways. First, if the national economy grows, businesses and industries hire more workers. Some of the poor who are qualified to look for jobs may find employment. Then they will no longer be below the poverty line. Second, if society invests in the poor, the poor will become more productive. If the government spends money on social programs, education, and training for poor people, the poor will have the skills to offer. Then it is more likely that they can find jobs.
Finally, if the government distributes society's income differently, it raises some poor people above the poverty line. The government collects taxes from the non－poor and gives money to the poor. These payments to the poor are called welfare. In 1975 over 18 million people in the United States received welfare.
Some economists are looking for better solutions to the poverty problem. However, at the present time, many people depend on welfare for a minimally acceptable standard of living.

We may conclude from the passage that _______

A.poor people are bound to go out of the poverty line if they have chances to do business
B.welfare will enable people to be rich
C.employment is the best solution to the poverty problem
D.better solutions to the poverty problem are not found yet

The Industrial Age and Employment

The industrial age has been the only period of human history in which most people's
work has taken the form of jobs.The industrial age may now be coming to an end,and
some of the changes in work patterns which it brought about may have to be reversed.This
seems a daunting（大胆的）thought. But, in fact, it could offer the prospect of a better
future for work.Universal employment,as its history shows,has not meant economic freedom.
Employment became widespread when the enclosures of the 17th and 18th centuries
made many people dependent on paid work by depriving（剥夺）them of the use of the
land,and thus of the means to provide a living for themselves.Then the factory system
destroyed the cottage industries and removed work from people's homes.Later,as
transport improved, first by rail and then by road, people commuted（乘车往返）longer
distances to their places of employment until,eventually,many people's work lost all
connection with their home lives and the places in which they lived.
Meanwhile,employment put women at a disadvantage.In pre-industrial times,men
and women had shared the productive work of the household and village community.Now it
became customary(惯例的）for the husband to go out to paid employment, leaving the
unpaid work of the home and family to his wife.Tax and benefit regulations still assume this
norm today,and restrict more flexible sharing of work roles between the sexes.
It was not only women whose work status suffered.As employment became the
dominant form of work,young people and old people were excluded-a problem now,as
more teenagers become frustrated at school and more retired people want to live active lives.
All this may now have to change.The time has certainly come to switch some efforts
and resources away from the utopian（乌托邦的）goal of creating jobs for all, to the urgent
practical task of helping many people to manage without full-time jobs.

Many people depended on the land for a living before the 17th century.
A:Right
B:Wrong
C:Not mentioned

Some people hate everything that is modern.They cannot imagine how anyone can really like modern music;they find it hard to accept the new fashions in clothing;they think that all modern painting is ugly;and they seldom have a good word for the new buildings that are being built everywhere in the world.Such people look for perfection in everything,and they take their standards of perfection from the past.They are usually impatient with anyone who is brave enough to experiment with new or to express himself or the age in materials original ways.It is,of course,true that many artists do not succeed in their work and instead produce works that can only be considered as failures.If the work of art is a painting,the artist’s failure concerns himself alone,but if it is a building,his failure concerns others too,because it may damage the beauty of the whole place.This does sometimes happen,but it is completely untrue to say,as some people do,that modern architecture is nothing.
We can’t judge every modern building by the standards of the ancient time,even though we admire the ancient buildings.Technologically,the modern buildings are more advanced.The modern architect knows he should learn from the ancient works,but with his greater resources of knowledge and materials,he will never be content to imitate the past.He is too proud to do that.
