Question:

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?

 （注意加粗的部分：雅思作文中，為了防止多數(shù)同學(xué)寫偏題，大家應(yīng)該首先把題目中的內(nèi)容性實(shí)詞畫出，只要這些詞在文中出現(xiàn)并是論述的核心，你的結(jié)構(gòu)性分?jǐn)?shù)就會(huì)上去。）

中文自寫提綱：

觀點(diǎn)一：化肥+農(nóng)機(jī)=  食品  制造成本降低

觀點(diǎn)二：化肥+農(nóng)機(jī)=損害健康，危害社區(qū)

觀點(diǎn)三：支持觀點(diǎn)二

            建議
                        A，管制化肥

                        B，尋找新化肥

                        C，改進(jìn)農(nóng)機(jī)

（用中文寫提綱的好處：思路清楚，反應(yīng)快。寫到后面時(shí)，提綱可能會(huì)有微小變動(dòng)，但大部分不能變動(dòng)，否則一定會(huì)偏題。）
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：可以從大面開始分析，切忌照抄題目，會(huì)被扣分。）

（首段結(jié)構(gòu)：僅提出雙方觀點(diǎn)即可，可以簡單寫自己觀點(diǎn)，也可以不寫。記住，雅思作文貴在“不說一句廢話”。）

the former school （類別） 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.

（這個(gè)段落層層遞進(jìn)，目標(biāo)只有一個(gè)：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：建議中間段落的首句盡量簡短，這樣的寫法有力量感，簡潔明快，容易獲得考官的認(rèn)同。）

（第二句注意these的用法：適當(dāng)使用“這個(gè)”“那個(gè)”“這些”“那些”，不只是詞匯的問題，更能夠向考官證明你的思路是“連貫的”，這是明確的加分點(diǎn)。）

（這個(gè)段落層層遞進(jìn)，目標(biāo)只有一個(gè)：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.

（很多人都會(huì)漏寫這一段，但只要仔細(xì)觀察大綱，你就會(huì)發(fā)現(xiàn)，還有machinery和local community沒有講）

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：自己的觀點(diǎn)還是要首先擺明再開始論證。）

（第二句的結(jié)構(gòu)注意：may … but … 這種“柳暗花明”結(jié)構(gòu)是雅思閱讀中常見的陷阱結(jié)構(gòu)，是雅思考官的最愛，如果你在考試?yán)锬苷�確使用，那你賺翻了。）

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.

（解決問題的方法也是幾句就簡明說完，不要啰嗦�？蛇m當(dāng)采用there are things we can do 這個(gè)句型。）
