With our entrance to 21st century, there rises the controversy of whetherour future would turn to the bright one. Many people claim that 21st centurywould be taken into a positive way through scientific and technological advancewhile a great number of pessimists argue that our future is threat123d by lotsof ongoing disasters. As for me, I prefer a balanced view that there will becrisis and opportunities.

On one hand, we have reasons to be optimistic. For one thing, thedevelopment of information technology will make it possible to for all thepeople in the world to communicate with each other easily. Take the internet asan example. A simple click on the mouse could lead you to every place and personall over the world. For another, as the medical treatment develops, it could beexpected that there will be cure for such deadly diseases as cancer and AIDS andthat human beings would be able to enjoy a long life expectancy. Moreover, withthe ongoing mechanization, an increasing amount of dangerous and heavy-laborwork would tend to be taken by the robot. In this case, man can work in moresafe and comfortable conditions, as well as enjoy more leisure time.

On the other hand, it can be foreseen that there may be crises in thefuture. First, people will run high risk of psychological problems for dealingwith computers in long-term is likely to cause the loneliness and infantileautism. Consequently the rate of suicide would experience a sharp rise. Besides,there is possibility that the robot would take over the earth, enslaving ourmankind who is originally its creator. Furthermore, it is not impossible that aglobal nuclear war would break out. As a result, none of all creatures on theearth can escape this disaster so that from then on the civil history comes toan end.

From the discussion above, it can be concluded that we would confront bothopportunities and crises. The advanced science and technology could obtain meritand drawback. So what I hope to see in the future is that we can enjoy healthierand longer life and that more and more science and technology will be employedin the peaceful way.托福和雅思的区别

雅思考后经验总结

我在考前一个月就开始看绿皮书上的观点，并用本子记录几个我觉得我合用的观点，以便最后阶段易于复习。在考前两周，我在仔细研究课堂笔记和绿皮书上的例文、例句后，建了四个图表作文的模板和三个大作的模板(这里偷懒了，老师是叫建四个的)。之后，在平时看文章(主要是在21stcentury)时，注意学习些套句，然后换到模板中。在考前一天，我自己限时练习了一次，主要是为了计时，以模拟一下正式考试时的时间安排。我有意限定自己必须在55分钟内完成，因为考虑到在真实考场的情况，在压力下，思维和反应会没练习时快。

在雅思考试时，也没多想，其实也没时间多想。我就严格按照模板来写。完成第一篇图表作文，用超了几分钟，那时挺紧张的。幸好大作平时花的时间多，观点也熟，写下来都很畅顺。我记得很清楚，在考官宣布还有两分钟时，我就快写完最后一句话了。总的老说，观点熟和严格按照模板写作帮了我大忙。我认为熟读绿皮书和建好模板是非常有用的，可以说是救命稻草。
