Food can be produced cheaper if we use improved fertilizers and better machinery.
However some methods may be dangerous for human health, and may have negative effects for local communities.
What is your opinion?
（注意标红的部分：雅思作文中，为了防止多数同学写偏题，大家应该首先把题目中的内容性实词画出，只要这些词在文中出现并是论述的核心，你的结构性分数就会上去。）
中文自写提纲：
观点一：化肥+农机
预祝您雅思作文更上一层楼,感谢您阅读《雅思作文食品话题习作》一文.本文来自雅思作文网liuxue86.com《雅思作文食品话题习作》。 = 食品 制造成本降低
观点二：化肥+农机=损害健康，危害社区
观点三：支持观点二
建议
A，管制化肥
B，寻找新化肥
C，改进农机
（用中文写提纲的好处：思路清楚，反应快。写到后面时，提纲可能会有微小变动，但大部分不能变动，否则一定会偏题。）
agriculture has become one key word in the global debate of environmental issues. some hold that improved fertilisers combined with better machinery will amount to a significant reduction in costs of producing food, while others contend that negative impacts will also ensue on human health and on local communities.

（首句：可以从大面开始分析，切忌照抄题目，会被扣分。）
（首段结构：仅提出双方观点即可，可以简单写自己观点，也可以不写。记住，雅思作文贵在“不说一句废话”。）
the former school （类别） of thought stands on the ground that improved fertilizers and better machinery will increase productivity. fertilizers boost the capacity of each inch of ground to churn out crops, and machinery boost the capacity of man to harvest them. and according to the theories of economy of scale, overall cost for each kilogram of crops will correspondingly decrease.
（这个段落层层递进，目标只有一个：reduction of costs）
the second school has its point, though. fertilizers are unnatural products made of special chemicals. while these chemicals may enhance the productivity of the soil, they may also mutate the chemical make-up of the plants, either by affecting their genetic formation, or by getting themselves absorbed into the plants. the residues will remain in the food all the way to man's stomach. this will, of course, affect our health.
（首句：建议中间段落的首句尽量简短，这样的写法有力量感，简洁明快，容易获得考官的认同。）

（第二句注意these
预祝您雅思作文更上一层楼,感谢您阅读《雅思作文食品话题习作》一文.本文来自雅思作文网liuxue86.com《雅思作文食品话题习作》。 的用法：适当使用“这个”“那个”“这些”“那些”，不只是词汇的问题，更能够向考官证明你的思路是“连贯的”，这是明确的加分点。）
（这个段落层层递进，目标只有一个：effects on health）
also, as the second school maintains, there is the use of the machinery. tractors and harvesting machines, unlike farmers harvesting with their reaping hooks, bring exhaust fumes to the farms and local communities, which worsens air pollution.
（很多人都会漏写这一段，但只要仔细观察大纲，你就会发现，还有machinery和local community没有讲）
my judgement tells me that in the long term, we should advocate the second school of thought. we may be inspired by cheaper foods, higher consumptions and thus better GDP numbers, but if all these have to be traded at the price of our people's health, they are worthless. environmental interests have always been in conflict with economic developments, and the wiser way is to choose the latter's side.

（首句：自己的观点还是要首先摆明再开始论证。）
（第二句的结构注意：may … but … 这种“柳暗花明”结构是雅思阅读中常见的陷阱结构，是雅思考官的最爱，如果你在考试里能正确使用，那你赚翻了。）

there are, of course, things we can do. first, we can issue policies through legislation to restrict the use of fertilizers . second, we can develop new forms of nature-friendly fertilizers. third, we can reduce exhaust fumes on farms by encouraging the use of vehicles feeding on clean power, such as electricity or hydrogen fuels.
（解决问题的方法也是几句就简明说完，不要啰嗦。可适当采用there are things we can do 这个句型。）
