4.以科技为题写一篇英语简短的文章100字以上
The technology which surrounds almost everyone in the modern society, affects both work and leisure activities. Technology contains information that many would rather it did not have. It influences minds in good and bad ways, and it allows people to share information which they would otherwise not be able to attain. Even if a person does not own a computer or have credit cards, there is information on a computer somewhere about everyone. The technology which is just now beginning to be manipulated and harnessed is affecting the minds of small children and adolescents in ways that could be harmful. It is affecting our immediate future. It also gives another form of communication and exchange of information which was not available before, information that is both good and bad.
Technology is one of the principal driving forces of the future; it is transforming our lives and shaping our future at rates unprecedented in history, with profound implications which we can't even begin to see or understand. Many different elements affect how satisfied we are with our lives. The impact of technology on these elements can change how safe, healthy and happy people feel. Throughout history, people have looked for better ways to meet their needs and to satisfy their expectations. Technology has improved the way people feed, clothe and shelter themselves. Technology has also changed other aspects of everyday life, such as health care, education, job satisfaction, and leisure time activities. People have used technology since they first chipped stone blades to improve their hunting. Yet some people call the current age the "Technological Age" because of society's dependence on technology. For the first time in human history, almost all the goods and services people use depend on technology.The products of technology are available to almost everyone in society. The economy of a country influences how the people of

科技知识英文短文什么是清洁能源 Clean Energy Clean energies are forms of energy which do not pollute the air, the ground, or the sea.Clean energies include:Solar powerSolar power describes a number of methods of harnessing energy from the light of the Sun. It has been present in many traditional building methods for centuries, but has become of increasing interest in developed countries as the environmental costs and limited supply of other power sources such as fossil fuels are realized. It is already in widespread use where other supplies of power are absent such as in remote locations and in space.As the Earth orbits the Sun, it receives approximately 1,400 W / m² of energy, as measured upon a surface kept normal (at a right angle) to the Sun (this number is referred to as the solar constant). Of the energy received, roughly 19% is absorbed by the atmosphere, while clouds on average reflect a further 35% of the total energy. The generally accepted standard is 1020 watts per square meter at sea level.After passing through the Earth's atmosphere, most of the sun's energy is in the form of visible and ultraviolet light. Plants use solar energy to create chemical energy through photosynthesis. We use this energy when we burn wood or fossil fuels or when we consume the plants as a source of food.Wind power Wind power is the kinetic energy of wind, or the extraction of this energy by wind turbines. This article deals mainly with the intricacies of large-scale deployment of wind turbines to generate electricity.Wave power Wave power refers to the capture of ocean surface wave energy to do useful work including electricity generation, desalination, and filling a reservoir with water. Wave power is a form of renewable energy. Though often co-mingled, wave power is physiologically distinct from the diurnal flux of tidal power and the steady gyre of ocean currents which are powered by the earth's rotation. Wave power generation is not a widely employed technology with only a few experimental sites in existence.Salinity gradient powerSalinity Gradient is a technology that takes advantage of the osmotic pressure differences between salt and fresh water.If we place a semipermeable membrane (like that in a reverse osmosis filter) between sealed bodies of salt water and fresh water, the fresh water will gradually travel through the filter by osmosis. By exploiting the pressure difference between these two bodies of water we can extract energy commensurate to the difference in pressure.Tidal power Tidal power is a means of electricity generation achieved by capturing the energy contained in moving water mass due to tides. Two types of tidal energy can be extracted: kinetic energy of currents due the tides and potential energy from the difference in height (or head) between high and low tides.Geothermal power Geothermal power is electricity generated by utilizing naturally occurring geological heat sources. It is a form of renewable energy.Some renewable energies are not clean energies - for example:Biofuels because they release NOX and particulates into the environment. Hydroelectric power because it destroys the river basin and has a negative effect on fish migration.。

Ever since they were first put on the market in the early 1990s, gentically mondified (GM， 转基因) foods have been increasingly developed and marketed in many countries in the word,mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would ,is it the best solutiorr? Despite what it promiises,GM technology actually has not increased the production potential of any corp. In fact Studies show that the most crown GM croo. GM soybeans, has suffered reduced productivity. For instance, a report than analysed nearly two decades of research on mojor GM food crops shows that GM engineering has failed to significantly increase US crop production. Something else, however, has been on the rise, While GM seeds are expensive, GM companics tell farmers that they will make good profits by saving money on pesticides（杀虫剂）. On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. “ The promise was that you could use less chemicals and boost production. But nether is true,” said Bill Christison, President of the US National Farm Coalition. At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report. As a matter of fact ,scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which “green” farming is supposed to be the first choice.。
