the question “what does modern science bring us?” has always [1]provoked great debate. some people argue that science should [2]been responsible for pollution and has brought us the nuclear bomb that threatens our existence. [3]in addition, they point out that cloning has shaken the foundation of moral codes.

　　　　[3]however, [4]compared with the negative aspects, [5]i think, the blessing of science is more evident. as we see, the vast improvements made in the field of medicine have served to lengthen our life expectancy and to reduce the rate of infant morality. [3]what's more, the discovery of mechanization, better seeds, better technique of irrigation and pest control has worked to increase the productivity levels on farms. as to transportation, the railway, modern ocean liner, jet plane, and motor vehicles have made our lives more comfortable and convenient, [6]as well as provide more chances for commercial and industrial development. [3]besides, the invention of the computer has assisted a lot in our life and work.

　　　　[3]in general, [7]the advantages of science far outweigh its disadvantages. and in most cases, [8]it is not science itself but human beings' misuse of it that brings us undesirable results. [3]therefore, [9]it is no doubt that we should continue developing science and [10]take full advantage of it.
