The development of science and technology has brought about many changes in people’s lives. For example, the inventions of television and the space rocker have opened a new era for the mankind; Through the use of TV people can hear the sound and know the news from all over the world. Owing to the invention of spaceship and rocket, the dream of man’s landing on the moon, which was impossible several decades ago, has now is true.

Science and technology also play an important role in our socialist construction. To realize the four modernizations, we need to accelerate the development of science and technology. It is hard to image the modernization of industry, agriculture and national defence of our country can be realize without the application of modern science and technology . We may say, our socialist construction is just like a skyscraper, while science and technology is its base. Without the base, the skyscraper can’t be built.

Therefore, we should all try best to contribute to development of science and technology so that to provide a more solid base for our world.
