自从有了网络，就有了上网的人；有了上网的人，便有人说上网的利弊。今天，作为一个大学生，我是如何看待大学生上网的呢？我觉得应当一分为二的看。
网络最初是运用于企业的，用来查阅公司所需的资料，也用来洽谈生意。这时的网络尚未普及，可是，它的作用是积极的。此时的网络除了尚不完善外，我想还没有什么利弊之分。
随着技术的提高，网络日趋完善，也渐渐普及了。为了更适应大众的需要，有了网络游戏，有了QQ，有了各种各样的版块。于是，上网的人更多了，当然有大学生。大学生上网，理由是多种多样的。有的为了寻找一位网友以打发时间；有的为了网络游戏而不分昼夜；有的为了网上电影以此来“充实”生活。当然，也有为了学习的。我就亲耳听说一个建筑系的学生为了画图而包了两次夜。暂不说他包夜的行为是否不当，是否于身体不益，单说他对网络的利用，他在利用网络。我不得不插一句，何为“利用”呢？我觉得，在这，利用不是一个贬义词，而是一种积极的有效的运用。在科技日益发达的今天，借助于电脑，利用于网络，可以做成许多过去不能做或不易做的事。这是利？是弊？
作为一个旅游系的学生，我也是常上网的。在网上，可以看到很多有关旅游的信息。有景点的介绍，有旅游信息的发布，有国家对旅游业政策的公布。这些，可以说是最新、最快的。对于旅游业这样一个敏感的行业来说，早一步得到信息便意味着早一步抓住机遇。这是利？是弊？当然，网上也不全是可靠的信息，也有谣言，有谬论，如果不加辨别，一概采纳接受，并且因此而酿成巨大的失误。这又是利？还是弊呢？
网络是四通八达的，上了网，可以认识很多人。本地的、外地的、中国的、外国的，当然也会有好人、坏人。上了网，有了网友，互通有无，彼此相互联络，提供彼此意见、建议，建立一种良好的网上友谊。这是利？还是弊？整天沉迷于网上聊天，不上课，什么事也不干，只为了网上冲浪，与网络那端的人虚无缥缈地扯上半天，最后还有可能误入歧途。这是利？是弊？
人人都说网络奇妙，它能在瞬息之间把你想知道的东西呈现出来；可以搜索到一本你一直想找但苦觅不着的老版杂志；可以搜索到一些书本、报刊上还未出现的前沿知识。你可以用它来丰富自己，真正达到一种不出门就知天下事的境界，达到一种一台机便知前沿科学的境界。这是利？还是弊？也有这样的一种人，他们有着卓越的网络知识，利用网络来发财，一种不义之财。当然，这里的利用就不是我前文所提到的利用了，这也是一种运用，不过是一种具有破坏力的运用。如此说是利？是弊？
其实，网络本无利弊，利弊在于上网之人。学了马哲，知道人应当发挥自身能动性，上网也是如此。有时，利与弊只一线相隔，单看上网之人是如何把握的，是如何发挥自身能动性的。
如今，大学生上网已是一种趋势了，也可以说是一种必然的局面。利弊仍有人说，可如何把握利弊不是掌握在自己手中吗？

Teachers, students, people, science and technology on the development of big profits or big disadvantages identified the problem, our Friends of the debate agreed that the development of science and technology do more good than harm.
The survival of the human way, 20 million years ago and 10 million years ago, there will not be much change; in 3000 before the year 2000, there will not be much change; 600 years ago and 500 years ago , There will not be much change. However, modern and ancient past has long been a matter of fact, even now and 100 years ago, has been completely different. What is the impetus to the development of human history?

The development of science and technology is powerful, scientific and technological progress in the development of the Chinese nation is the driving force in the first, not science, where we are today's happy life? Not science and technology, where we have the comfort of the material and spiritual life to enjoy? Not the advances in technology, How could we get two hybrid? How could we wear cotton clothes, how can we live in high-rise buildings?
Asked Lee large scientific and technological development or major disadvantages? Needless to say, of course, big profits! Explain? Do not have to explain! Ba Qiannian the history of Chinese civilization, civilization is evidence, at all times in the history of changes in science and technology at all times In the development. Rumaoyinxue from the original human life or learn to Shao Shu use of food, from breeding to rely on natural farming, metallurgy from the unarmed to the rock Lian, this is not progress, this development is not? If the benefit is greater than the disadvantages, then why are human beings It also chose the same progress? Progress can only head for a better tomorrow!
