We Need to Broaden Our Knowledge
1．科学技术是社会发展所不可缺少的
2．社会科学和自然科学相互渗透
3．现代大学生需要广博的知识
    Knowledge is power,especially scientific and technological knowledge. Science and technology are the motive power of the social development. Without them human society could never have developed from primitive society to modern society. Therefore, to conquer and transform nature, we must master scientific knowledge.
    However,social knowledge is also essential. Without it we can not understand society and don't know the law of the social development. As a result we are unable to govern society. Therefore, besides scientific knowledge we need to master social science, philosophy, politics, history, aesthetics, etc, so that we can know society from all perspectives and form a correct world outlook.
    To meet new challenges in the 21st century, we university students should lose no time to acquire as much knowledge as possible so that we will become qualified for our future careers.
