写作思路：科技的发展对人类及社会的影响。
正文：
The level of modern science and technology has become a chip in the international political struggle and a symbol of the status of a great power.
现代科学技术水平已成为国际政治斗争中的一块筹码，是大国地位的象征。
Deng Xiaoping once pointed out: "if China had not had the atomic bomb, hydrogen bomb and satellite since the 1960s, it would not have become a great power with great influence, nor would it have such an international status as it has now."
邓小平曾经指出：“如果中国自20世纪60年代以来没有原子弹、氢弹和发射卫星，它就不会成为具有重大影响力的大国，也不会像现在这样具有国际地位。”
In today's world, peace and development are the themes of the times. However, the "cold war" mentality still exists, and hegemonism and power politics are still the main sources of threats to world peace and stability. The power of science and technology has become the common choice of modern countries.
在当今世界，和平与发展是时代的主题。然而，“冷战”心态依然存在，霸权主义和强权政治仍然是威胁世界和平与稳定的主要根源。科技力量已成为现代国家的共同选择。
first, the development of computer changes our life. decades ago, people needed to do lots of complex calculation on hand because they did not have computer, and more obvious, they did not have the software for calculation. as the result of that, people spent hours on the equations that a computer can solve in just a minute. since the development of computer, people are able to use some kind of software to compute lots of complex functions and mathematical calculation. computer becomes the most helpful equipment for the sciencists because they can use their time more efficiently.
also, internet is another useful tool for us today. the development of internet brings a great impact toward the society. instead of going to library and fliping all the books to figure out some information, we can just simply use a mouse and click on the website to do research. the internet leads us to a place where we can find unlimited information and resources. it makes our life much easier and better.
the last technology is cellphone. nowadays, many people have a cellphone. but it just appears on the market for about 10 years. it is very convenience to the users because we can talk to anyone we want with a phone as small as a wallet. also, we can communicate with others by making a phone call instead of sending letters. it is very fast and useful way to communicate.
in conclusion, i believe the development of technology brings significant impact to our life. it is very helpful to us and i believe technology will keep improving in future.
