范文三（知识就是力量）

Knowledge Is Power Recently there has been a discussion regarding the issue of knowl- edge in the newspaper. As can be seen from the picture， knowledge is symbolized by a clenched fist as power. The fist sends out a message for “obedience”， threatening to crack with power any hard nut. The more demanding and challenging a task is， the more powerful the fist seems to grow. Similarly， knowledge， the strongest power for human beings， feeds up the field of science and technology. The more ad- vanced and developed a field is， the more profound knowledge seems to become. A specific example is the dunaping of Mir， Russia‘s space station. As is the case of the Russian space program， the country could no longer afford to keep Mir aloft in orbit because of lack Of financial support. Therefore， Rus- sia decided to dump the space station. The effect is both immediate and far -reaching. As far as the present is concerned， the successful launching and dumping of IVrLr has proved to the world that mankind， armed with pro- fca. md knowledge， cannot just build things but can operate them welt. For the distant impact， the once- in- a- lifetime success of/VFtr provides man with valuable and indispensable experience for manned space flight in the years to crane. Then， someday in the furore， them might appear in space more Mirs， visiting Mars， spreading friendship， parading the perfect maste- ry of knowledge. As to the best way to master knowledge， I suggest that everyone of us “ask not what others will learn from you， but what you can learn from the others.” By so doing， I sincerely believe each person， pro- tected by’ the “fist”， will be learned and knowledgeable.

From this cartoon， we can see that at the top end of the river， is a chemical factory and a paperrnaking factory which send out and poisonous wastes. And the river has been seriously polluted， n be seen from the color of it. Along this “black” river， there are a few people selling fresh water which must have been taken from far away places. At the first glance， it is very strange to us how can people sell wa- ter along the river， but this is the case， because the water in this river is undrinkable. This presents a serious social problem——environmental pollution. With the development of economy， our living standards have been greatly improved. But we can‘ t ignore the fact the air we take in and the water we drink today are not as fresh and clean as they used to be. Some kinds of pollution can even be deadly to people. It is high time that we took some measures to solve the problem. I think we can first call people’s attention to this problem so that they will be aware of the serious consequences of it. Then，we can pass certain laws to restrain the factories from sending out wastes. Finally， we can do more resarch work to find out ways to deal with the wastes.

 Keep Square Clean， Tidy On Sunday， still on display on Tian‘ anmen Square were dozens of floats that were paraded along Chang’ an Avenue during the National Day celebrations. Thousands of people strolled on the narrow lanes be- tween the floats that fragmented the square， busily taking photos. Not far from the noisy crowds， yellow leaves fell nonchalantly from locust trees along the driveway， sending out the first signals of the coming autumn. But even if all the leaves fall， they still cannot cover the brown and black spots on the whitish stones in the huge square. Such stains of chewing gum， stale oil or some worse blemish have remained a constant pain for city cleaners since the square ‘was re- opened a few months ago after renovations to celebrate the 50th anni- versary of the founding of the People’s Republic of China. Few renovation project planners likely foresee this discouraging outcome. Originally， they merely intended to give the city a face- lift. The square was indeed impeccable when new： The-white terrazzo surface not only looks clean but it was made with materials that help prevent it from becoming slippery. However， as time goes by， the virtue becomes the vice： the sur- face attracts and accentuates dirt. As a result， China‘ s most high - profile site has to suffer the indignity of being paraded daily before the public in a humiliation state. While the tourists who litter should bear the bulk of the blame， the renovation designers should also have learned something： including the square’s sanitary maintenance issue into their consideration.
