我觉得电脑是我们学习中的好伙伴，电脑可以用来查资料，电脑可以用来看你最想了解的新闻，电脑可以用来写博文，发表你自己的文章，发表你自己的意见，和大家一起交流，还有电脑的键盘还能有助于你左右手的.配合能力。
我心目中的电脑并不是十全十美的，它也有缺陷，什么缺陷呢？
电脑虽好但是要劳逸结合，太多的接触电脑也不好，因为电脑有辐射，据说辐射对人体极其不利，而且电脑还对眼睛有损害，玩电脑多了，可就要带上“二饼”的哟！。
还有就是电脑游戏，有的同学玩电脑游戏简直都玩疯了，也不学习了，也不回家了，就在网吧一直玩，告诉那些爱玩电脑游戏的同学，电脑游戏不是不可以玩，要适当的玩，电脑游戏里面的人物都是虚拟的，不是真正的，比如：摩尔庄园、奥比岛、网娃......就是先勾引你到这个网站上玩，然后，就让你买什么米米卡、Q币.......买那些卡的钱，都投到网站里了，当然那个网站就赚钱了，好像就是这么一个过程。
我们现在是小学生，我觉得小学生要注重学习，玩游戏会占用太多的时间，会影响学习的。
电脑是让你学习里面有意义的东西，不仅仅是玩游戏，还要合理的利用电脑，这样你才会学到更多的知识。

Everyone has goals. Many people do not reach their goals for lack of planning. These three sets of goals should be developed: lifetime, intermediate and short term.
Lifetime goals should be written out. These goals should be clear and reasonable. F
or instance, the goal to win a research prize is clear and measurable. Other lifetime goals might include publishing a certain number of influential books or articles, earning a departmental chairmanship at a major university, successfully competing for a grant from the National Science Foundation or securing a consultantship with a big corporation. Intermediate goals relate to outcomes during the next few years. For the beginning doctoral student, intermediate goals may include completion of course work and preparation of a doctoral research proposal. Like lifetime goals, these are measurable and clearly stated.
Short-term goals involve outcomes expected during the next 12 months. These goals are more performance oriented, and they help with achievement of intermediate goals. Examples of short-term goals are earning an A in a course, learning how to program a computer or performing an experiment.

People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man’s release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance, such as oil from oil tankers into the sea.
The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produced there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods.
Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself if gradually becoming worn out as it is being used, in some cases, too heavily, and artificial fertilizers cannot restore the balance.
Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy.
Pollution and waste combine to be a problem everyone can help to solve by
cutting out unnecessary buying, excess consumption and careless disposal of the products we use in our daily lives.
