1、Science and technology have been bringing human beings tremendous benefits.Thanks to science and technology,we now live comfortably and conveniently in houses furnished with air conditioners,refrigerators,washing machines and televisions etc.Thanks to science and technology,we can eat fresh vegetables att the year round.Thanks to science and technology,we can travel tong distances in the fraction of a second on planes,trains and cars.Thanks to science and technology,we wear clothes with synthetic materials which can not easily be worn out.
However,science and technology have atso brought us a tot of disasters.First,because of the many breakthroughs in the field of medicine,people are now living much longer than they used to.As a result,the population of the world is increasing,causing tots of problems.Second,because of the development of industry,tots of the wastes from factories pour into the air and rivers,causing pollution of att kinds.Third,some terrorists are using science and technology against mankind.They use biological,chemical and unclear weapons to threaten world peace.

Nowadays,our lives have great changed.Why?Because science and technology are developing continuously and the development of science is making influence on our ideas of life.
At early age,people only wanted to get sufficient food and clothes.They didn’t know how to deal with the challenge from nature,such as bad weather,animals’ attack and so on.
Then,people began to know some of world and learnt some technology.They were no longer satisfied with the basic requirements.They began to make an attempt at obtaining fortune by making full use of nature with the help of science,in spite of the ill effect on the surroundings.
Now,we have realized that we should consider for not only ourselves but also future generations.So we lay emphasis on environmental protection at the moment that we develop the economy.We know more and more about ourselves and world.Meanwhile,we find that we just learnt a little in the fact.As a result,people do more and more explorations.And,the explorations promote the development of society so that our lives change.
I believe that our lives will be better and better with the development of science and technology and the change of our thinking of life.
