The development of science and technology makes our life more comfortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions.
Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before.
Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel.
Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable.
However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources become scarce.
Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.

现代科技使生活更加便捷(Modern Technology Makes Life More Convenient)
Modern technology makes life more convenient; tools are the milestores of the technology as well as human being’ s progress.
Men used to cut trees with hand saw. But now, by using electronic saw they can cut down a tree in only a few minutes. Another example is more vivid: You have something urgent which has to be informed to your friend whose house is two hour’s ride away. You probably want to make a phone call. But no telephone is installed in your friend’ s home. What could you do? Nowadays, with modern technology advanting, using internet is popular with us. Some years ago, people had to get what they wanted through looking into a lot of information; at last people could become tired and spent too much time. Now, if you use Internet, all becomes a piece of cake. Only by clucking, you will gain what you expect.
We all hope that modern technology will reach a higher level, because modern technology makes life more convenient indeed.

现代科技使生活更加便捷
现代科技使生活更加便捷；工具是科技进步和人类进步的里程碑。人类过去用手锯锯树，但是现在，用电锯可在几分钟内锯倒一棵树。另外一个例子更加生动形象：如果你有急事通知你的朋友，而他家距你家有2小时的路程，你可能想打个电话。但是你的朋友家又没安电话，你该怎么办?如今，随着现代科技的进步，使用网络已很流行。若干年前，人们不得不查找大量资料来搜集需要的信息，最后人累得疲惫不堪，还浪费了大量时间。现在，如果使用网络，一切就都是小菜一碟了。只要轻敲键盘，就会有求必应。
我们都期待着现代科技能达到一个更高的水平，因为现代科技确实使生活变得更便捷。
21st century is the century of technology. Nowadays， technology is everywhere around us. The development of technology has a significant affact toward the society. Several technologies that we usually use are the internet， computer， and cellphone. These new technologies make our life much easier and better.
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.

As is vividly depicted by the picture above, a traveler happily starts his journey by high-speed railway from Guangzhou to Wuhan. In the year of 2009, Wuhan-Guangzhou high-speed railway went into operation, reducing travelling time from 12 hours to 3 hours, bringing much convenience to the transportation between the two cities①. No wonder the caption in the picture says “with the Wu-Guang high-speed railway, cities far away is just like a place nearby”。
Science and technology are the primary productive forces② and have been playing a key role in the national economy development. On the one hand, progress in science and technology has promoted economic and social progress greatly. Take the high-speed railway as an example. Firstly, the railway becomes a new engine③ of booming of regional economic. Secondly, the railway helps to attract a lot of tourists, so that tourism in these cities flourishes. Last but not the least, the load of the existing transportation network can be released to a great extent. On the other hand, with the development of science and technology, such as the operation of high-speed transportation, video phone, webcam meeting, the world has become smaller and smaller。
It has long been a tradition for Chinese government to attach great importance to the advances④ in science and technology. Science and technology has successfully shaped an entirely new image of China on global stage via the two grand world events, 2008 Olympic Games and 2010 Shanghai World Expo. It is strongly advised that young people should devote themselves into the study of science and technology for “better city, better life”。

如上图所示，一位旅客从广州踏上了去往武汉的高速铁路。2009年，武广高铁正式建成通车，将两地之间的行程从12小时缩短到3小时，极大地方便了两地的交通。难怪这幅漫画上写道“有了武广高铁，每个城市都在家门口”。
科技是第一生产力，在国民经济发展中扮演着重要角色。一方面，科技的进步促进了经济社会的快速进步。高速铁路就是鲜活的例子。首先这条铁路成为地区经济发展新的引擎。其次铁路吸引了大量游客，这些城市的旅游业随之繁荣起来。再次这条铁路很大程度上缓解了现有线路的运输压力。另一方面，随着科技的发展，高速铁路，视频电话，视频会议等应用会越来越多，世界将变得越来越小。
中国政府一直很重视科技的发展，通过2008北京奥运会和2010上海世博两件盛事，科技成功地重塑了中国在世界舞台上的国际形象。因此青少年要怀着“城市，让生活更美好”的信念，积极投身到对科技文化知识的学习上。
