对论?
什么类型的活动?
你要根据活动的主旨来完善你的演讲内容.
主要观众成员是学生?
初、高中学生还是大学生?
没有太多的时间给您直接写,但是给您牵个引子,您可以借鉴下港大校长徐立之先生在百年校庆典礼上的致辞中的一段话：
We cannot pretend that we are living in a stable and peaceful world.We face natural disasters almost everyday,energy shortages,global warming,emerging infectious diseases,recurring epidemics,man-made accidents,precarious economic crises,abrupt social turmoil and unwanted wars.We know that some of these are unavoidable,so we have to do our best to mitigate or learn to overcome their effects with our scientific knowledge and technological advancements.For the entirely avoidable ones,however,we have a responsibility to safeguard sustainable development,and to champion the restoration of human values.
以此为中心引出儒家的名言“修身齐家治国平天下”,然后引出当前中国青少年所缺少的一些东西,这样会比较好.
