　　Knowledge economy was still something unheard of just a decade a90.But today it has become a household word and is on everybody’s lips.Knowledge economy is not only a concept now，but will be a reality in near future.At the turn of the century，a new knowledge economy age is approaching us.

　　In the l980s，when people talked about the Third Wave and the post-in-dustrial society，knowledge economy remained a concept yet to be crystal-lized.However，in the l990s，with knowledge playing an increasingly vital role in every sphere imaginable of our economic life，a knowledge—based economy is gradually taking shape.Simply stated，knowledge economy is a kind of economic system based on the production，storage，distribution and consumption of knowledge and information products，Knowledge economy is knowledge—intensive，energy—saving as well as environment-friendly.In the knowledge economy era，economic development relies heavily on science and technology.For example，the information industry in the US has already ac— counted for l0%of its gross domestic product and is expected to enjoy a further increase in the years to come.

　　This imminent knowledge economy age presents both vast opportunities and immense challenges to every nation.Worldwide competition in knowledge and information，science and technology，inventions and patents，natural and human resources will become even more fierce.As the saying goes，“Knowledge is power”，and so the gap between countries，in the final analysis，is the gap of knowledge.To meet these challenges posed by knowledge economy，our country should raise the overall quality of her labor force and cultivate more and more specialized personnel.

　　Human Activity and the Earth

　　【托福写作题目】

　　Some people believe that the Earth is being harmed (damaged) by human activity. Others feel that human activity makes the Earth a better place to live. What is your opinion? Use specific reasons and examples to support your answer.

　　【托福写作范文】

　　There is no doubt that human activity has an effect on the planet. We see the evidence of mankind's endeavors all around us. While some of man’s accomplishments, such as the building of transportation systems and the consistent supply of potable water, have made Earth a better place for people to live, they have not come without cost. Overall, it seems that human activity harms the Earth more than it benefits it.

　　For example, the transportation systems that benefit mankind also create pollution and use up valuable energy resources. While we cannot do without transportation these days, we cannot ignore the fact that it has an adverse effect on the planet. Furthermore, those advances that benefit people do not benefit all the life on Earth. Deforestation endangers many animals, and mankind's great thirst for water and other resources leads to the extinction of many plant forms. In addition, accomplishments such as the supply of potable water to a community are only responses to problems that mankind created in the past. It was man that made the water unfit to drink in the first place. Finally, the damage that human activity causes will eventually have a negative effect on people. They will also suffer the effects of pollution and diminishing natural resources.

　　In conclusion, it seems apparent that man's activity benefits primarily himself, not the Earth. Moreover, those benefits are only short-term advantages, and man will also suffer the negative effects of his activity in the future. The Earth does not have an inexhaustible supply of resources, so every effort should be made to conserve resources and limit the impact of human activity on the planet.
