  托福写作难点话题一览

  Does human activity improve or damage the earth?

  写作思路展开结构分析

  看完题目大家先不要急于选择。其实两种观点无论是哪个都过于含混。Human activity指的是什么? 比如饮食起居,东南亚地区把某种海豚(dolphin)吃得almost extinct;美国人养宠物鹦鹉(parrot),导致南美洲很多稀有品种(rare species)濒临灭绝;又比如科学研究,好的例子很多,比如电的发明;不好的也很多,克隆(clone)技术、基因重组(gene engineering) 技术,可能导致道德(moral value)的沦丧(deteriorated; ruined); 诺贝尔的发明(炸药explosive)究竟杀 了多少人?塑料袋(plastic bags)的发明,导致了多少white pollution? 战争:从来都是灾难。生化武器,比如炭疽病毒(anthrax) 所以比较合理的结论应该是:人类的行为对地球的影响,有好的,也有坏的。很难说哪一种更多。大家可以从这个角度来展开。

  本话题高分范文赏析

  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.

  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.
