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. Rocketsand 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.

It’s my great honor to stand here and share my presentation about ‘Advantages and disadvantages of rapid development of science and technology’.
When I had the first glance at this topic, I suddenly came to think of the composition in the College English Test Band 4 which I take in last term. In that part of test, we are asked to write a short essay according to a given picture. In the picture, a pair of parents are facing with a computer on the first floor in an apartment. On the screen is a sentence of irony, ‘Dear son, How is your life going on the second floor? We miss you so much. ’Obviously, the picture reflects the common problem in our daily life. Technology has made us and close relatives and friends more distant.
We can’t deny that the great benefits brought about by the progress on science and technology is hided in every corner of the world. Modern communication tools such as mobiles and QQ make it possible to send message in a handy way. The Internet enables a pupil to accomplish a university graduation thesis. Powerful networking information storage makes incalculable social activity in an orderly way. Sophisticated scientific techniques even help human to explore other planets. Anyway,
the finding of the second earth may give human a new
accomadation after the earth is destroyed. That sounds not bad. As we can see, the rapid development of science and technology has brought great changes to our life. However, some of the influence it takes is not so optimistic. Just like the example I reffered at the beginning. Communicating through social networking website is becoming a threaten to people’s real life. Against to it’s original willing, we gradually fade out in the crowd. Despite this, children lack essential
interpersonal skills. Those who indulge in I pad or I phone often isolated and being cut off from the outside world. They tend to be more introverted, self-centered and withdrawn. From another point of view, the technique makes using tools on a large scale become a consequent tendency. You must hear of the industrial revolution which caused two job cuts over the whole world. Nowadays, the bad influence may even worse. The mature assembly line work is controlled by automatic machine.
Thereupon, a large amount of workers get unemployed. It is not benefit to stabilize society. Some of scientific inventions have also done great harms or disasters to mankind. And advanced technology can be easily manipulated by irresponsible persons or countriees.
It is just easy to think of something, but difficult to give down-to-earth execution. We should avoid the negative effects while enjoying the great convenience. I believe that, once we try, we are bond to keep the balance of advantages and disadvantages.

Science and art are the obverse and reverse of Nature's medal; the one expressing the eternal order of things, in terms of feeling, the other in terms of thought.
Science has long had an uneasy relationship with other aspects of culture. Think of Galileo’s 17th-century trial for his rebelling belief before the Catholic church or poet William Blake’s harsh remarks against the mechanistic worldview of Isaac Newton. The schism between science and the humanities has, if anything, deepened in this century.
Until recently the scientific community was so powerful that it could afford to ignore its critics--but no longer. As funding for science has declined, scientists have attacked “anti-science” in several books, notably Higher Superstition, by Paul R. Gross, a biologist at the University of Virginia, and Norman Levitt, a mathematician at Rutgers University; and The Demon-Haunted World, by Carl Sagan of Cornell University.
Defenders of science have also voiced their concerns at meetings such as “The Flight from Science and Reason,” held in New York City in 1995, and “Science in the Age of (Mis) information,” which assembled last June near Buffalo.
Anti-science clearly means different things to different people. Gross and Levitt find fault primarily with sociologists, philosophers and other academics who have questioned science’s objectivity. Sagan is more concerned with those who believe in ghosts, creationism and other phenomena that contradict the scientific worldview.

in the near term, china completed its first sars virus genome sequencing, sars is now the world’s largest recognized the dangers of the disease, but why not other countries completed first, and we just completed the countries? very simple, this illustrates that our country backward than others, worse than others, we look at the past, had just started a country’s reform and opening up to the current level of science and technology has lead a large country, our motherland experienced a number of ups and downs, how many difficulties and bumpy however, we still back all of the motherland, the motherland because we firmly believe that - not only technological change destiny, can change the future.
for our generation, the general feeling of the community is a strong sense of competition, learning a foot down.

we have to understand the importance of technology, know that the technology universal.
