　　『范文』

　　The environment is usually changed to benefit human life. Cars and roads make transportation fast and easy,

　　factories make products that make our lives more comfortable, public services in cities like water treatment,

　　electricity, and waste disposal make our lives more convenient. All of these advances, however, come with a

　　significant environmental cost.来源：北京新航道托福培训 Human activity does significant damage to the Earth.

　　One of the main effects of human activity on an area is water pollution. Dumping waste materials from

　　human activity into rivers and streams is popular because the waste seems to disappear downstream. The main

　　sources of water pollution are factory waste, oil and gas runoff from highways, and untreated human waste. When

　　this waste dumped into rivers, the water downstream becomes undrinkable and unusable for agriculture, and also

　　kills plant and animal life in the rivers.

　　Clean air and water is a prerequisite not only for human life, but also for all life on the planet. But air is now

　　being polluted by modern transportation, notably gas-powered automobiles, as well as electrical generators that

　　burn fossil fuels and pour polluting chemical waste into the air. This makes the air much less healthy to breathe.

　　The air-borne pollution also falls back to the earth in the form of acid rain, which destroys plant life and human

　　buildings.

　　Another serious long-term effect of air pollution is global warming. For the past several decades scientists

　　have noted a disturbing rise in the average temperature of the earth that caused by the rise of greenhouse gases, air

　　pollutants created by burning fossil fuels, in the atmosphere. Scientists believe that if humans continue to increase

　　the amount of greenhouse gases in the atmosphere, the temperature of the earth will continue to rise. Eventually,

　　this could melt the polar ice caps and cause devastating costal flooding all over the world. Major cities like Hong

　　Kong, Shanghai, and Dalian might be totally destroyed.

　　Therefore, I believe human activity has caused serious problems while it has improved the world in which

　　we live. It is time to realize this hazard and take action to prevent further disaster while making progress.

　　上面的写作话题和文章，大家可以用来练习和总结。其实，写作并不难，无论做任何事情，只要努力想办法去解决，就会有收获。相信大家都可以成为写作高手。希望大家都能轻松的应对托福写作，写出好文章。
