今天满分帝同大家分享的是雅思大作文科技类话题,各位烤鸭们擦亮眼睛往下看吧!
1题目
The increase in food production owes much to the use of improved fertilizers and better machinery, but some people think that it has a negative impact on human health and community. To what extent do you agree or disagree?
2题目翻译
食物产量的增长是由于改良肥料的使用和更高效的机械作业,但是有人认为这会对人体的健康和当地不利。你在多大程度上同意或是不同意?
3题目解析
此题考查的是话题中的科技类,属于科技类中的农业科技,也是最难的一类。科技类属于雅思考试中的高频话题,2018年已经考过5次科技类的题目了。提问方式属于最高频的同意与否类。此题将农业科技题目的难度降到了最低的程度,题中已经点明影响的范围是human health和community,答题细心点便不容易跑题。有相关题目如下:
1. The range and quality of food have changed because of technological and scientific advances. Some people think the range and quality of food have improved, while others think these changes would be harmful. Discuss both views and give your opinion.
2. Many people support the development of agriculture, such as factory farming and creation of new fruits and vegetables. Others oppose to this idea. Discuss both sides and give your personal opinion.
4解题思路
首先这篇文章我们可以采用四段式
开头段:背景句+话题引出+亮出观点
正文段一:机械作业和改良肥料使用带来的好处(让步段)
正文段二:对人体健康和当地带来的负面影响(同意部分)
结尾段:观点+总结至少一个论点
Ps:正文段如若论点够多,也可展开2段或多段。
5确定论点

6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.(标红为核心论点)
