science and technology in modern life
human life cannot continue without science and technology. for many centuries, human society develops with the advance of science and technology. so the life we are living now is more civilized than that of our forefathers.
the development of science and technology has brought about many changes in people’s life. for example, the invention of television and the space rocket has opened a new era for mankind. through the use of tv people can hear and see the events, which happened or, are still happening thousands of miles away. owing to spaceship and the rocket, the dream of man’s landing on the moon has now come true.
science and technology also play an important role in our social construction. we may say that our social construction is like a skyscraper that cannot be built up without the help of science and technology. 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.

what would happen if there were no power
ever since early this century, electricity has become an essential part of our modern life. it has played a decisive role in modern industry, agriculture, science and technology, national defense and education. nobody can deny that the development of our civilization depends on electricity.
if there were no electric power, our modern world would be in great trouble. for one thing, all the wheels would stop because the motors that power the machines would stop. for another, many of our industries would cease production. and all the electrical equipment such as washing machines, refrigerators, tvs would stop working. in short, our modern life would be impossible without electricity.
therefore, we should make better use of electric power. on the one hand, we should educate people to economically use electricity and not to waste the energy resources for the future. on the other hand, we must do our best to exploit more electric resources to meet the requirements of the human beings and to avoid energy crisis in the future.
