      The twentieth century saw greater changes than any century before: changes for the better, changes for

the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. Many

things caused the changes, but, in my opinion, the most important was the progress in science.

     Scientific research in physics and biology has vastly broadened our views. It has given us a deeper

knowledge of the structure of matter and of the universe; it has brought us a better understanding of the nature

of life and of its continuous development. Technology m the application of science m has made big advances

that have benefited us in nearly every part of life.

     The continuation of such activities in the twenty-first century will result in even greater advantages to

human beings: in pure science-a wider and deeper knowledge in all fields of learning; in applied science-a more

reasonable sharing of material benefits, and better protection of the environment.

     Sadly, however, there is another side to the picture. The creativity of science has been employed in doing

damage to mankind. The application of science and technology to the development and production of weapons

of mass destruction has created a real danger to the continued existence of the human race on this planet. We

have seen this happen in the case of nuclear weapons, Although their actual use has so far occurred only in the

Second World War, the number of nuclear weapons that were produced and made ready for use was so large

that if the weapons had actually been used, the result could have been the ruin of the human race, as well as

of many kinds of animals.

     William Shakespeare said, "The web of our life is of a mingled yarn (纱线), good and ill together. 'The

above brief review of the application of only one part of human activities-science-seems to prove what

Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically

programmed for war?
