Written by Jasmine

The range and quality of food that we can buy has changed because of technological and scientific advances. Some people regard this change as an improvement, while others believe that it is harmful.

Discuss both views and give your own opinion.

很多同学觉得关于转基因食品很难写，因为对转基因食品的争议一直存在，连专家也无法下结论。所以同学们写作过程中应将话题与实际生活相结合，将话题与我们的生活学习结合在一起讨论，这样的文章更安全。

下面来看看北外网课的老师是怎样写的吧。

范文-intro. P

As the top club member of food chain, human being has never stop to enlarge the variety and amount of edible things, and technology is now playing an crucial role. The fierce and ongoing debate over GM food reveals the benefits as well as potential danger of it.

范文-Supporting. P1

Proponents of genetically modified foods argue that GOMs increase yields and decrease chemical reliance. The genetic engineering methods used on crops, vegetables and fruit have enhanced the nutritional, productive and ecological value of the species. Organic crops are vulnerable and easily damaged by adverse weather conditions or pest attack. However, genetically-altered crosses, such as hybrid rice, are pest and disease resistant, which make the stable production possible. Thus, the world can be fed and the range of food is expanded.

范文-Supporting. P2

Despite those merits, opponents of GMO crops claim that they are risky and harmful. Since the recombinant DNA technology is current instable, which means that no one can predict the long term effect of it on both human and environment, we should not put our future in danger. Although the resistant traits of GM crops are highly praised, more hazards can be expected. There will be super pests which can not be killed by any pesticide, and it will not be easy to control these super organisms. The negative result on eco-environment may be  irreversible. The food chain will be broken as a result of crops being resistant to predators.

范文-conclusion. P

After weighing the pros and cons of GM foods, I think the crux of the matter is the unpredictable consequence. We should not oppose the fast-paced development of biotechnology and genetic engineering, but both government and food manufacturers should take responsibilities to control the adverse effects of GM food, and currently GM food should be labeled at least to inform the consumers.

以上内容同学们好好研习，相信对雅思写作会有较大提高。
