29.Somepeople believe that the Earth is being harmed (damaged) byhuman activity.Othersfeel that human activity makes the Earth a better place to live. What is youropinion? Use specific reasons and examples to support your answer.
参考分析：
不要急于选择。两种观点都过于含混。Human activity指的是什么？
饮食起居：广东人把某种海豚(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。
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)
结论：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。

Topic 29 Has human harmedthe Earth?
People have learned how to turn wild natural areas to farmland, how to exploit minerals to adapt their needs, how to build roads andhouses to expand their territories. People continuously improve their knowledgeand develop technologies to improve their lives. It is undeniable that theseactivities of human beings make their lives better than ever before.Nevertheless, those activities also cause side-effects to the Earth because ofpollution, deforestation, and exaggerated natural resource exploitation.
Nowadays, pollution becomes one of the most concerned problems.Because of the increasingly expanded factories, the industrialized areas, theburning of population etc, too much pollutant spills out everyday.Consequently, all of these things cause bad effect to the Earth. The purity of atmosphereis reduced seriously, the Earth is continuously warmed up, and ozone layer isholed.
Additionally, forest is asking for help in desperation.For last few decades, the forest areas have been reduced to 50 percent becauseof human deforestation. Green forestland of the Earth can be compared to thelungs of human. How healthy you are if their your lungs are trespassed. I am surethat you will get more difficult with aspiration; as a result, your health willbe affect badly. From this example, we can infer that how serious problem ourEarth has to face with. I wonder how long it can endure.
Researchers show that the natural means is limited, but today,they are exploited so increasingly to adapt infinite human needs that someday,all mineral can be ended up. Because of serious pollution, alarmingdeforestation and progressive mineral exploitation, the ecosystem becomes unbalance.Consequently a lot natural calamities happen each year such as flood,hurricanes. A lot wild living creatures are exposed to narrow place of shelterand lacking foods. For these reasons, the Earth will become unhealthy.
In conclusion, the human beings harm the Earth. Human beingsas well as their dear planet, the Earth, have been badly suffered by whatcaused by humans themselves. I hope that humans are soon aware of thoseproblems so that they can have suitable policies in order to not only improvetheir lives but also keep and maintain the Earth fresh and green. |
