22021年12月18日雅思高分范文及解析

Introduction

A conundrum of modern societies is the declining level of health in the general population, such as corpulence, which can be partly ascribed to people’s preference for unhealthy foods despite the fact that they know the detriments. Personally, behind such preference are two predominant factors, and this thorny issue can hopefully be tackled.

解析

说明文题型，问原因和解决办法。该话题与12月2日刚考过的话题相似：Shops should not be allowed to sell any food or drink that has been scientifically proved to be bad for people’s health. To what extent do you agree or disagree? 这题干不就是一种解决办法嘛?另外，剑16 Test 3 以及 6月17日考题，都是与健康饮食相关的题。

Ø conundrum n. 难题

Ø corpulence n. 肥胖，臃肿

Ø be ascribed to 被归因于

Ø detriment n. 坏处

Reasons

To commence, the sound flavour that junk food offers should be responsible for the unhealthy diet. This is mainly because those unhealthy foods are usually sugar-, salt-, or fat-laden ones high in calorie and GI, which, after being eaten, will stimulate nerve cells to produces dopamine, a chemical functioning as a neurotransmitter to convey bliss and excitement. For this reason, people prefer or even easily get addicted to sugary beverages and fatty foods, especially the ones whose mouthfeel has been enhanced./ Besides, it is due to the surging living pressure that most employees nowadays have to work non-stop. In this case, they tend to order these instant foods, usually unhealthy ones, which fit the current fast-paced life.

解析

原因1：好吃;原因2：压力大 → 快节奏的生活→ 一些不健康的食品，比如快餐，比较适合这种趋势

Ø laden adj. 满载的，装满的(lade的过去分词)

Ø dopamine n. 多巴胺

Ø function as v. 起…作用

Ø neurotransmitter n. 神经递质

Ø mouthfeel n. 口感

Solutions

Considering the gravity of this trend, two schemes can be put on the agenda. The first approach is that policies regarding subsidisation can be issued by governments to motivate manufacturers to develop diet and delicious products. Meanwhile, the subsidies can also to some extent reduce the production costs, which will guarantee the newly-developed products sold with a proper price. Besides, high tax could be imposed on unhealthy food products. In this way, producers will thus have to raise the price for the sake of ensuring their profits, which naturally follows that ordinary people are more likely to consume the aforementioned cheaper but healthy alternatives.

解析

整体方案就是调控价格：1. 用补贴鼓励公司研发健康美味的产品，同时降低新研发产品的售卖价格;2. 提高不健康食品的税收 → 售卖价格提高 → 人们选择买前面更便宜且健康的食品

Ø diet adj. 低脂肪的，低糖的

Ø impose vt. 征收

Conclusion

To recapitulate, since possible culprits and feasible remedies have been enumerated, this crisis can be promisingly resolved with joint efforts of relevant parties.

解析

重申观点

Ø recapitulate v. 总结

Ø culprit n. 罪犯;(不好事情的)原因

Ø remedy n. 治疗方案;解决办法

Ø promisingly adv. 有希望地

Ø joint efforts 通力合作
