写作例子

科技发展对人类的影响:

The place of technology in modern society is a subject of continuing controversy. Key issue includes not only the impact of technology on quotidian life but also the need to control the development and uses of technological innovations so that they benefit all aspects of community.


正面:

any technological developments during the last century have helped reduce human suffering. Consider, for instance, technology that enables computers to map Earth’s geographical features from outer space. This technology allows us to locate lands that can be cultivated for feeding malnourished people in third-world countries. And, few would disagree that humanity is the beneficiary of the myriad of 20th century innovations in medicine and medical technology—from prostheses and organ transplants to vaccines and lasers.


20th century technological innovation has enhanced the overall standard of comfort level of developed nations. The advent of steel production and assembly-line manufacturing created countless jobs, stimulated economic growth, and supplied a plethora of innovative conveniences. More recently, computers have helped free up out time by performing repetitive tasks: have aided in in the design of safer and more attractive bridges, buildings, and vehicles; and have made possible universal access to information.

反面:


For every new technological breakthrough that helps reduce human suffering is another that serves primarily to add to that suffering. For example, while some might argue that physics researchers who harnessed the power of the atom have provided us with an alternative source of energy and invaluable “peace-keepers”, this argument flies in the face of hundreds of thousands of innocent people murdered and maimed by atomic blasts, and by nuclear meltdowns. And in fulfilling the promise of “better living through chemistry” research has given us chemical weapons for human slaughter. In short, so-called “advance” that scientific research has brought about often amount to net losses for humanity.


Technological development has already brought about environmental problems.


Many things these days cause pollution such as cars, air conditioners, refrigerators, factories, etc. All these things together can cause a pollution problem in the society today. Refrigerators and air conditioners are a problem to the zone because of the liquid called Freon--when these liquids are released from damaging the machine, it releases a gas that breaks down the zone layers. In addition, cars also can cause a lot of pollution because of the carbon monoxide it produces. This would cause the air to be bad, cause global warming, and would also cause acid rain.


哥白尼日心说:(opposite to “Earth-centric Theory”)


Copernicus' theory of heliocentricism is sure to be a great achievement in astronomy, however, his great discovery contradicted the traditional and in-powered theological canon which dictated geocentricism , his book was censored and prohibited from the general public, it was not until several years published in other countries did Copernicus first express his ideas to populace.

阿基米德Archimedes


Greek mathematician, engineer, and physicist. Among the most important intellectual figures of antiquity, he discovered formulas for the area and volume of various geometric figures, applied geometry to hydrostatics and mechanics, devised numerous ingenious mechanisms, such as the Archimedean screw, and discovered the principle of buoyancy.


利用点:通才与专才,从小的兴趣影响,科学的偶然发现


When Bill Gates made his decision to drop out from Harvard, he did not care too much of the result. Many people did not understand why Gates gave up such a good opportunity to study in the world's No.1 University. However, with size comes power, Microsoft dominates the PC market with its operating systems, such as MS-DOS and Windows. Now, Microsoft becomes the biggest software company in the world and Bill Gates becomes the richest man in the world.


利用点:自学成才


As a matter of fact, the whole history of discovery is filled with people who used erroneous assumptions and failed ideas as stepping atones to new ideas. Columbus thought he was finding a shorter route to India. Johannes Kepler stumbled onto the idea of interplanetary gravity because of assumptions which were right for the wrong reasons. And, Thomas Edison knew 1800 ways not to build a light bulb. We can learn from the experience of these predecessors that sometimes a series of apparent failures is really a precursor to success. The voluminous personal papers of Edison reveal that his inventions typically did not spring to life in a flash of inspiration but evolved slowly from previous works.


利用点:失败是成功之母
