　　We Need to Broaden Our Knowledge
范文：
    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.
