英语翻译科学技术是人类战胜自然、改造自然的武器,是推动社会生产力发展的重要力量.科技的每一次发展都是人类文明史上的飞跃,

science and technology is the weapon for human being to defeat and remodeling the nature, and also the drive to promote the development of social productivity forces. every development of science and technology is the leap of human civilization, and also the success of human subjugate nature, conquer themselves.
there is also someone who thinks science&technology is the cause of environmental problems, the development of science and technology cannot solve any environmental problems , instead it will bring new and much more serious environmental problems.
in my view, the answer to ' science and technology is angel or devil' cannot be simply solve by literally looking up to the word and generally answered . on the contrary, it should be more based on deeply analyzing, specific and special treated. unless, the answer would not be appropriate.
