雅思写作另类归纳分类总结:食品安全类-质疑生物科技

雅思写作越来越与现实生活中的热点问题息息相关,最近雅思写作就考到了一道生活科技相关的题目。今天墨尔本文波雅思来给大家分析一道真题。

食品中化学添加剂给人类带来各种急性和慢性的疾病,然而,有很多生物科技在农作物或食品生产中起到促进生产,保障食品质量的作用。例如,转基因玉米(genetically modified crops)等,人类人口数量的膨胀急需大量此类产品来缓解粮食紧张的困境。另外还有许多土地贫瘠的干旱地区也需要生物科技来刺激农作物的生长。

雅思真题中却有一题是对生物科技的质疑,

Biotechnology could bring negative effects to nature and human beings so that should be banned, to what extend do you agree or disagree?

It is undoubtedly the case that biotechnological advances and their wide applications in growing various genetically modified crops are having a significant impact on nations’ traditional ways of life. Some people argue that the production of these modified foods could have detrimental effects on nature and the environment and therefore should be banned. I personally, however, completely disagree with this point of view for two reasons.

主体段一,给出第一个理由支持生物科技,其中给出关于非洲生产力低下,亚洲国家人口膨胀,对大米的需求无法得到满足的例子。有许多高级词汇诸如,饥饿(hunger predicament),贫穷(poverty-stricken),贫瘠土地(barren land)

Firstly, with the world’s population increasing by 86 million a year, genetically modified crops may be urgently needed to alleviate the hunger predicament. It is often seen on the media that millions are reported to suffer from malnourishment and all kinds of related diseases every year. Especially in poverty-stricken areas, such as Africa, people there do not have enough to eat all year around, mainly due to the poor planting conditions, including barren land and drought. Moreover, as for many Asian countries where people mainly live on rice, there might not be a sufficient rice production guaranteed to feed the projected 4.6 billion people by 2025. Feeding the world is an ever-growing problem, and, therefore, developing the genetic make-up of crops and making them proliferate throughout the world is desirable and only a matter of time.

主体段二,第二个理由是由于这些转基因科技虽有一些负面影响,但和大气污染,温室效应,工厂污染等相比,并没有致命的缺点,与其带来的巨大作用是无法相比的。

Secondly, according to recent data released by a team in DNA research for crops, products that are resistant to pests, drought and disease are aligned with nature rather than fighting against it. These crops are not something dangerous that will have disastrous impacts on the whole environment, and are nowhere as bad as the pollution brought by heavy traffic, industrial pollution and many other ways of contamination. There is no better way to increase the crop yield than enhancing the genes responsible for drought tolerance and pest resistance. Thus, the scientific breakthrough of genetically modified food benefits human beings considerably and outweighs the potential damage it could bring to nature.

In conclusion, the DNA adjusted crops programme is a great way to solve the pressing famine problem, and this with little pollution induced, makes it an extremely worthwhile project for mankind’s future.
