What should we do?
As a college student living in the 21st century , we should have a right attitude towards technology.
• Firstly, make use of technology. •Secondly, avoid the negative impact of technology. •Thirdly , we should learn more about the science and technology. In a word, be sensible to the use of technology and have an objective attitude towards technology.
Modern science and technology
Scientific inquiry and technological development form the bedrock of modern human civilization. In the past two centuries, we put men on the moon, explored the deepest oceans, eradicated diseases, found an elusive Boson, and solved most problems of the human condition through the breakthroughs provided by scientific discoveries and their technological implementations.
Advantages
2. Industries are rapid development so as to let human beings into the era of hot weapons from the era of cold weapon. 3. When paper and printing technology come out, people have written conditions and it promotes the extensive exchange of people of culture 、art、language、technology、 economic and so on. 4.The emergence of compass promote the development of navigation and trade, complete the geographical discoveries, let people know the earth 5.The invention of gunpowder is good for people to built brige、building and road.
