雅思写作题目讲解
【关键词分析】
food
农业包括种植业、畜牧业和渔业，生产出来的都叫food，不要局限在种植业上。
the health of humans and local community as a whole
人类的健康与当地，文章一定要紧扣这两点影响。community不单单指的是人类社会，而是泛指人居住的整个生态环境，这个词请考生留意。 (community: a particular group of animals or plants that all live or grow together.—柯林斯COBUILD英汉双解词典)
雅思写作大作文范文：
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.
尽管将机械和化肥应用于农业的好处显而易见，但其后续效应肯定不适合自然环境和人类健康。很有可能，如果没有一系列与农业机械和农业化学知识相关的连续的发明，当前的世界人口将无法得到足够的维持。现在越来越多的人知道，这样的耕作方式会导致不良的污染和致命的疾病。
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.
从表面上看，经济效益是很多的。为了说明这一点，更好的机械化农业可以让更少的人耕种更多的土地。因此，农场工作变得更有效率，更节省时间。此外，新肥料的使用产生了更高的产量，因为许多可利用的土地变得更肥沃。作为一个综合的结果，食物更便宜，这对消费者来说当然是有利的。很容易看出，由于机械和化学技术的发展，一系列的积极变化已经发生，从准备土壤到种植种子到采集收获到加工作物。
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.
从不同的角度看，这些变化有隐藏的缺陷，影响着人们的健康和社区的空气和水的质量。首先，农业设备需要柴油来运作，这就造成了空气污染。因此，使用的机器越多，农村的空气污染就越严重。似乎还不够糟糕，人类的健康受到了化学物质的滥用，最终导致了土壤中的水污染。最糟糕的是，据说一些健康问题与农产品有关。研究人员还发出了令人震惊的警告，称污染食品与各种疾病之间存在联系，包括醉酒和癌症。
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.
总之，很明显农业现代化并不总是好的，不可避免地会产生一种混合的祝福和诅咒。事实是，在没有机器和肥料的情况下，现在几乎是不可能的，特别是在全球人口快速增长的情况下。如果没有别的，在这个时候全世界都在紧张地期待着环保机器和无风险肥料的到来。
