Air Pollution

Air pollution is one of the major problems of the modern world. A great deal of energy is needed to
run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too.
Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which
remain in the air, causing air pollution.



Scientists are finding ways to stop air pollution especially in big industrial areas and densely-
populated cities. They are studying new ways of generating electricity that may be less damaging to
the environment. In the meantime, many power plants are being modernized to give off less polluted
material. Also, engineers try to design and locate new power plants to do minimum damage to the
environment.



However, it may be that we still have a long way to go before we have a
of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end
to tasks that environmentalists will be required to do. People will continually find new ways to control
pollution.

The place of Science and Technology in Modern Life

Human life can not continue without science and technology. For many years, human society has
developed with the advance of science and technology while the development of science and
technology has in turn brought the process to mankind. So the life we are living now is more civilized
than that of our fore fathers.



The development of science and technology have brought about many changes in people's life. For
example, the invention of television and space rocket have opened a new era for mankind. Through
the use of TV people can hear the sound and learn the events happening thousands of miles away.
Owing to the invention of spaceship and rocket, the dream of man's landing on the moon has now
come true.



Science and technology also play an important role in our socialist construction. We may say, our
socialist construction is just like a skyscraper, while science and technology are its base. Without the
base, the skyscraper can't be built. Therefore, we should try our best to contribute to the development
of science and technology so as to provide a more solid base to build our country.

Importance of Education

China, as a developing country, is determined to catch up with and even surpass the developed ones. I
think that one of the best possible ways to do so is to give first priority(优先to the development of
culture, science and especially education.



In modern times, when science and technology are making great progress, the education of the work

force is of primary importance. Moreover, many of the success in advanced countries have
demonstrated that a nation 's prosperity mainly depends on the quality of its labour force, namely
those who have been well educated.



In a developing country such as China, our investment in culture, education and science, and
especially elementary education, must enjoy top priority. This is crucial(决定性的for China to catch
up with the developed nations in today's surging(汹涌的 waves of technological revolution. Otherwise,
the gap between China and advanced countries will be widened rather than bridged.

Environmental Protection

Today the quality of our natural environment has become an important issue. The world population
is rising so quickly that the world has become too crowded. We are using up our natural resources and
at the same time polluting our environment with dangerous chemicals. If we continue to do this, life
on earth cannot survive.



Concerned people have made some progress in environmental protection. Governments of many
countries have established laws to protect the air, forests and sea resources and to stop environmental
pollution.



Still more measures should be taken to solve environmental problems. People should be further
educated to recognize the importance of the problems, to use modern methods of birth control, to
conserve(保存 our natural resources and recycle(再循环 our products. We are sure that we can have a
better and cleaner place in the future.



Automobiles



Automobiles, as a product of modern civilization, have been playing a vital part in the daily
activities of human society. Industry needs automobiles for farming as well as transportation. Every
day, automobiles drive people to and from work. On weekends automobiles take families for joyful
outings. And during holiday seasons, automobiles fill the highways everywhere, even in remote areas.
It could be said that the wheels of automobiles move society forward.



But automobiles have also given rise to a series of problems. For example, cities are overcrowded
with automobiles. They create a lot of noise and traffic accidents which disable(伤残 or kill many
people each year. Worst of all perhaps is the air pollution caused by the exhaust gases produced by
automobiles. Some of the gases are highly toxic(有毒的 and a serious health hazard.

Computer



The computer is widely used in all fields of society. Today, wherever you go, you will find
computers being used. For example, computers are used in universities, large corporations, and small
offices, etc. It has even entered the homes of ordinary people. As it is able to store and process a large
amount of information, the computer bring about great convenience and high efficiency to people of
all walks of life.



Computers can help people in different ways. For example, computer help scientists in analyzing
data and doing complex calculation. For another example, computers are made use of by engineers in
designing a plane, or a spaceship. Besides, computers may also play a great role in helping children
with their lesson. Whatever you are doing, you many find computer a useful aid.



However, the computer must be designed and instructed by man. What is more, it is true that
computers can make decisions, but they need detailed instructions and programs prepared by humans
to operate. Therefore, the computer can never replace the human brain.
Choosing an Occupation

Every one faces the problem of choosing an occupation after graduation from college or university,
which plays a vital role in his life. An appropriate occupation makes a man work with zest(热情 and
vigor, as well as contribute to his country.



To make a wise choice, two important things should be taken into consideration. One is the interest,
the other, the demands of people and society. Only if the two aspects are connected, can a man show
his talent and ability to the best advantage. If the two conflict, the former should be under the latter,
for the people's interests are more important than the individual's.



In regard to my choice in the future, I am fond of learning foreign languages; what is more, with the
implementation of the Open-Door Policy, exchange between home and abroad in economy and culture
has been growing significantly, thus I'm determined to be a qualified interpreter.
Energy Resources

China is rich in various energy resources. Coal and petroleum, for instance, are two major ones.
They are essential in developing the country's industry, science and technology. China has done a
great deal in the past few decades to raise its output of coal and petroleum.



Three energy resources are being used up rapidly, With the building of four modernization, new
industrial and science projects are springing up like bamboo shoots after rain. They are all big

consumers of energy resources. Besides there has been considerable waste in the utilization of these
resources.



To avoid an energy crisis in the future, the government must take certain measures. First, it should
let people know the importance of saving energy. Second, efforts should be made to develop new
energy resources, such as solar energy, geothermal(地热 energy and so on. We have reason to be
optimistic in this respect.
Competition

Competition makes people original and creative. It very necessary to compete if human society
wants to advance. (Even animals compete for survival. Without it, we would become lazy and nobody
would rake any responsibility. When three monks live together, there will be no drinking water. This
Chinese proverb vividly describes why China's productivity was so low before Mr Deng came to
power. At that time, we had the so-called planned economy. There was no competition at all. So
neither farmers nor workers worked hard. China was on the edge of collapse.



Competition can stimulate people to try their best to do anything. For example, in 100-meter race,
each sportsman runs as quickly as possible, trying to win the champion. The same things happen in
our society and in our daily life. If a company wants to surpass others, it must compete with them. It
must raise its efficiency. All the companies doing this will no doubt benefit the whole society and the
whole human race.



Being a student, I must compete with other students in our studies. I must study hard in all the fields
so that I can be a useful man when I enter the society after graduation.
Students
’
Part-time jobs

There are many advantages for a student to have a part time job. For instance, it helps him to realize
that no success comes from nothing. It enables him to be independent and builds up his self-
confidence. Therefore, part-time jobs can get the students out of the ivory tower and give them the
opportunity to know more of himself and of his personal value in society.

As everything coin has two sides, the disadvantages can’t be ignored. Part- time jobs cut into
students’ study time; some even become so preoccupied with making money that they can ‘t focus
their attention on studying. In the end, the students may fall behind or fail in their studies.



In my opinion, students can choose to take up a job according to their own situation. The most
important thing is for him to keep a good balance, put his study on top of the list and assign an
adequate amount of time to it.

Wealth and Happiness

Everybody wants to get wealth. In today’s material world, making money or becoming wealthy

symbolizes a person’s success and capability. Many people just make every effort, pay any price to
attain greater wealth. With money, they can but nice, large apartments in nice neighborhood; with
money, they can own stately luxury cars. Wealth seems with money, they can own stately luxury cars.
Wealth seems to bring all happiness in life.



In my opinion, people cannot do anything without money, but money is not everything. What
money will bring you depends on your personal belief and goal in life. If you are kind enough to help
others, especially the poor, money is a good thing to you. With it, you can do much more for the
benefit of people and your country, and it will and to your own happiness. If you want money just for
your own needs, you’ll never be satisfied or happy. In a word, you should have money spent for more
people, only then can money be the source of your happiness.

Is Failure a Bad Thing?

Failure is what often happens. It is everywhere in our life. Students may fail in exams, scientists
may fail in their research work, and athletes may fail in competitions.



Although failure happens to everyone, attitudes towards failure are various. Some people don’t
think their failure is a very important thing at all. So they pay no attention to it. As a result, they will
have the same failure a period later. Some people think themselves are fools and lose their hearts in
everything after they get a failure. Consequently, they spend their time and energy on useless things
and they may really be fools as they have thought.



Other people are quite different from the two kinds of people mentioned above. Instead of being
distressed and lost, they draw a lesson from every failure and become more experienced. After hard
work, they will be successful in the end. It is said that failure is the mother of success. Success will be
gained after times of failures so long as we are good at drawing lesson from our failures.



In my opinion, failure is not a bad thing, the really bad thing is taking a failure as failure or even
lose our heart after failure.

Modernization of Family Life

With the rapid development of the society, family life is becoming modernized. Years ago, people
considered owing radios, sewing machines, watches and bicycles as being modernized. But in recent
years, almost all families have TV sets, refrigerators and washing machines. It is very common to see
people ride motorcycles or even drive private cars and more and more families have telephones,
computers and air- conditioners.



The modernization of family life brings us convenience and comfort. One may enjoy TV or radio
programs, communicate with his friends through telephone or work with his computer while his
washing machine, refrigerator and air- conditioners are running. And by car or motorcycle one can

quickly reach wherever he wants to go.



In spite of this, these modern facilities also bring us disadvantages. For example, radiation from TV
sets and computers is harmful to our health; improper driving of cars and motorcycles becomes the
major cause of traffic accidents. The quietness of a family is often disturbed by a falsedialing or
unwelcome phone call. But it is believed that these disadvantages will be disposed of with the
improvement of modernization and our life will be more healthy and more comfortable.
