雅思寫作大作文高分范文：使用化肥是否影響人體健康

　　Food has become cheaper and food production has increased thanks to enlarged manufacturing capacity, the use of fertilizers and better machinery. However, some people believe that this will do harm to the health of humans and the local community as a whole. To what extent do you agree or disagree?

　　雅思寫作題目講解

　　【關(guān)鍵詞分析】

　　food

　　農(nóng)業(yè)包括種植業(yè)、畜牧業(yè)和漁業(yè)，生產(chǎn)出來的都叫food，不要局限在種植業(yè)上。

　　the health of humans and local community as a whole

　　人類的健康與當(dāng)?shù)?，文章一定要緊扣這兩點影響。community不單單指的是人類社會，而是泛指人居住的整個生態(tài)環(huán)境，這個詞請考生留意。 (community: a particular group of animals or plants that all live or grow together.—柯林斯COBUILD英漢雙解詞典)

　　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.

　　盡管將機械和化肥應(yīng)用于農(nóng)業(yè)的好處顯而易見，但其后續(xù)效應(yīng)肯定不適合自然環(huán)境和人類健康。很有可能，如果沒有一系列與農(nóng)業(yè)機械和農(nóng)業(yè)化學(xué)知識相關(guān)的連續(xù)的發(fā)明，當(dāng)前的世界人口將無法得到足夠的維持?，F(xiàn)在越來越多的人知道，這樣的耕作方式會導(dǎo)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.

　　從表面上看，經(jīng)濟效益是很多的。為了說明這一點，更好的機械化農(nóng)業(yè)可以讓更少的人耕種更多的土地。因此，農(nóng)場工作變得更有效率，更節(jié)省時間。此外，新肥料的使用產(chǎn)生了更高的產(chǎn)量，因為許多可利用的土地變得更肥沃。作為一個綜合的結(jié)果，食物更便宜，這對消費者來說當(dāng)然是有利的。很容易看出，由于機械和化學(xué)技術(shù)的發(fā)展，一系列的積極變化已經(jīng)發(fā)生，從準(zhǔn)備土壤到種植種子到采集收獲到加工作物。

　　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.

　　從不同的角度看，這些變化有隱藏的缺陷，影響著人們的健康和社區(qū)的空氣和水的質(zhì)量。首先，農(nóng)業(yè)設(shè)備需要柴油來運作，這就造成了空氣污染。因此，使用的機器越多，農(nóng)村的空氣污染就越嚴(yán)重。似乎還不夠糟糕，人類的健康受到了化學(xué)物質(zhì)的濫用，最終導(dǎo)致了土壤中的水污染。最糟糕的是，據(jù)說一些健康問題與農(nóng)產(chǎn)品有關(guān)。研究人員還發(fā)出了令人震驚的警告，稱污染食品與各種疾病之間存在聯(lián)系，包括醉酒和癌癥。

　　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.

　　總之，很明顯農(nóng)業(yè)現(xiàn)代化并不總是好的，不可避免地會產(chǎn)生一種混合的祝福和詛咒。事實是，在沒有機器和肥料的情況下，現(xiàn)在幾乎是不可能的，特別是在全球人口快速增長的情況下。如果沒有別的，在這個時候全世界都在緊張地期待著環(huán)保機器和無風(fēng)險肥料的到來。
