译文：
朋友是一个永不消失的话题。人类为何要有朋友呢？
首先，人是一种社会性动物。身为一个人，你就必须处在某种社会关系之中，说得简单点就是要与人沟通。一个孤立的人不能够算得上是一个社会的人。于是，人际交往成为了我们共有的人生话题。
其次，人总会有快乐和悲伤。感情的释放是需要朋友的。当你开心的时候，有人能够和你一起笑，你才能感到真正的喜悦；当你遇到困难的时候，有人能够和你一起承担，你才能够更加坚强的走下去；当你执着的追求自己的梦想时，有个人能和你一样饱含激情，你才会更加坚定自己的信念。这个人就是朋友。
然后，因为世界是庞大的，而个人是渺小的，所以你必须依靠朋友才能够有更宽的知识面，才能提高你的能力和丰富你的人生。
最后，当朋友困难的时候，你可以给予他帮助，这会让你更深刻的感受到自己存在的价值。这种积极的心态有助于你更好的生活。
与朋友交流，可以拓宽你的视野；与朋友合作，你会在学习和事业中取得更大的进步；向朋友学习，你会变得更加完美。世界就是因为人和人关系的逐渐密切而不断发展的。
