　　雅思写作对本来不太擅长语法逻辑的大陆考生来说是取得的一大门槛，与雅思培训中的其他几项做比较，写作要考察我们的能力比较多，包括语言构架能力，整体逻辑能力等;想要得着实不易。那怎么才能在诸多不利因素下自己呢?除了多积累词汇，还要多看范文，多和范文做比较，找出自己的不足，及时改正。下面北京新航道学校的雅思老师就为大家介绍一些雅思写作方面的材料和大家一起交流学习。

　　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.

　　积累词汇和写作范文无疑是雅思写作的两个关键方法，但同学们要在雅思培训老师的指导下循序渐进的，我们要知道没有一口吃出的胖子，过于求成的心态反而会让我们得不偿失。祝愿大家都能取得满意的成绩。
