海外大學(xué)教師謝振禮原創(chuàng):農(nóng)機肥料
真題回憶:
這回的Task 2題目幾年前曾經(jīng)在中國出現(xiàn)過。最近也重現(xiàn)南美。以下2012-5-19真題回憶(不十分準確),印象中應(yīng)該八九不離十。
》起段 Introduction:
農(nóng)機肥料--好處人人皆知;壞處有所不知。
》承段 BodyA (正面):論證
利用農(nóng)業(yè)機器,既省時間又省人力馬力牛力。顯然的是農(nóng)地生產(chǎn)提高,同時農(nóng)品價錢降低,造福消費百姓。另一方面,采用化學(xué)肥料也是大大的改善施肥的方式,保持土地的肥沃,可謂功不可沒。
》轉(zhuǎn)段 BodyB(負面):論證
農(nóng)機用燃料發(fā)動,因此造成環(huán)境污染。化學(xué)肥料可能也污染水土,所以很不可靠。長久吃可疑的農(nóng)產(chǎn)品必定對健康不利,甚至小命難保。
》合段 Conclusion
農(nóng)機肥料--禍福交雜。但求減少污染,還是采用無毒肥料為妙。

原創(chuàng)范文:
Although the advantages of applying machinery and fertilizers to agriculture are too obvious to be denied , there are after-effects that are certainly not in favor of natural environment and human health. It is probable that, without a continuous string of inventions related to agro-machines and agro-chemical know-how, the current world population could not be sufficiently sustained. Nowadays, it is increasingly known that such farming methods nevertheless contribute to undesirable pollutions and fatal diseases.
At a glance, economic benefits abound. To illustrate, better mechanized agriculture allows more land to be farmed by fewer people. Farm work therefore becomes more efficient and less time-consuming. Added to that, the use of new fertilizers creates higher yields because much of available land is made more fertile. As a combined result, food is cheaper, which of course benefits consumers in general. It is easy to see that, thanks to mechanical and chemical technologies, a series of positive changes have been made, ranging from preparing the soil to planting seeds to gathering the harvest to processing the crop.
Looking from a different angle, there are hidden drawbacks to such changes, affecting people's health and the quality of air and water in the community. For one thing, agricultural equipment requires diesel fuel to operate, which causes air pollution. Thus, the more machines are being used, the more air pollution there is in the countryside. As if it were not bad enough, human health is endangered by the abuse of chemical compounds, eventually leading to water pollution under soil. Worst of all, reportedly some health problems are associated with farm products. Researchers have also sent shocking warnings against the possibility of links between polluted foods and various diseases, including intoxication and cancer.
In sum, it is clear that modernization in agriculture is not always good, inevitably giving rise to a mixed feeling of blessings and curses. The truth is that it is next to impossible now to do without machines and fertilizers on farms, especially when the global population is growing rapidly. If nothing else, at this point the world is nervously expecting the coming of environment-friendly machinery and risk-free fertilizers. (Essay created by Jeenn Lee Hsieh)
