We Need to Broaden Our Knowledge
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 tovern 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 he 21st century, we university students should lose no time to acquire as much knowledge as possible so that we will become qualified successors of the socialist cause.
我们需要拓宽知识面
知识就是力量，尤其是科技知识。科学技术是社会发展的动力。没有它们，人类社会永远不可能从原始社会发展到现代社会。因此，要征服和改造自然，就必须掌握科学知识。
然而，社会知识也是必不可少的。没有它，我们就无法了解社会，也无法了解社会发展的规律。因此，我们无法支配社会。因此，除了科学知识，我们还需要掌握社会科学、哲学、政治、历史、美学等，这样我们才能从各个角度认识社会，形成正确的世界观。
迎接21世纪新的挑战，我们大学生应该抓紧时间学习尽可能多的知识，成为社会主义事业的合格接班人。
