这篇文章的第一端，CET4可以借鉴。。不管什么在中国的发展，都可以看成是无烟的工业，然后就是改革开放的套话。第2段主要是针对给中国带来的好处。如果考试中有外国到中国来消费的，不管是什么原因来消费，好处都可以是这2个科技类文章的写法（我采用正反结合的方法） 

Science and technology have brought about tremendous changes in people’s life. 

Scientific researches continue to open up previously undreamed of possibilities. Fifty years ago, few people could even imagine things like computers, space—shuttles. Now all these newly emerging technologies are benefiting people all over the world. In a word, advancing science and technology have made man master of the globe. 

As is known to all, everything has two coins. When we are enjoying the remarkable wonders which science and technology have brought us, we are suffering at the same time from a lot of troubles, such as environmental pollution, noise, green—house effect and the danger of nuclear wars. Let’s take cars for examples. They not only pollute the air in the city, but also make our roads overcrowded. Moreover, they are responsible for a lot of traffic accidents, which bring grave consequences both to the country and to victim’s families. 

As a result, we should not underestimate the other side brought by the progress of science and technology. 

这篇文章的第一段我是建议大家看熟的。因为不管是什么文章，在生活中给我们带来好处的原因，我归纳就三条：改革开放；科技进步；文明提高。如果说改革开放，前面的文章对次强调了，这里不说了。文明提高，明后天再说。这里让大家看看科技进步提高生活如何说。从第2段到第3段，是让害怕写科技类文章的朋友借鉴的，我从正反论述，再加个举例。如果已经熟悉用框架的朋友，那完全可以按照框架 
（3）去写关于具体措施的，多数情况下可以套的文章（以保护森林为例） 

My suggestions to deal with problem are as follows. In the first place,we should appeal to the government to set up a foundation to reward thost do much to protect resources. Secondly, those who cut down trees in a forest at radom 
must be punished by the law. Finally,it is necessary to encourage city-residents to plant as many trees as possible in and around the city. We are looking forward to a much better and brighter future. 

评注：这篇文章的解决办法的模式是我想推荐的。第一步，呼吁。第二步，惩罚。 
第三步，奖励。如果考到假 伪劣产品，也可以套吧，如果考到经济发展，那也可以饶到企业的诚信和the public的监督。反正只要和“保护”有关的，都可以用这个模式。
