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

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

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

From the discussion above, it can be concluded that we would confront both opportunities and crises. The advanced science and technology could obtain merit and drawback. So what I hope to see in the future is that we can enjoy healthier and longer life and that more and more science and technology will be employed in the peaceful way.

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。之后，在平时看文章时，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。
