在我们的雅思写作学习中，我们首先要明白的是我们的文章结构。我们的task2 大作文部分根据题目的最后一句话可以把题目分成五种类型。而每种类型都对应不同的写作结构。所以熟悉作文的不同写作结构使我们写好作文的步。今天长沙新航道雅思写作小编就这种双边讨论类型的结构做一个讲解。这类作文本身就要求我们两边都要讨论，并给出个人观点，所以我们在写的时候这3个部分都不能缺少。那我们在写的过程中，到底应该写几段，每段安排什么内容哪?我们今天就用剑桥9， test 3 的大作文部分做个讲解。
Some people say that the best way to improve public health is by increasing the number of sports facilities. Others, however, say that this would have little effect on public health and that other measures are required. Discuss both these views and give your own opinion.
A problem of modern societies is the declining level of health in the general population, with conflicting views on how to tackle this worrying trend One possible to provide more sports facilities to encourage a more active lifestyle.
Advocates of this believe that today’ s sedentary lifestyle and stressful working conditions mean that physical activity is no longer part of either our work or our leisure time. If there were easy to-reach local sports centers, we would be more likely to make exercise a regular part of our lives, rather than just collapsing in front of a screen every evening. The variety of sports that could be offered would cater for all ages, levels of fitness and interests: those with painful memories o PE at school might be happier in the swimming pool than on the football pitch.
However, there may be better ways of tackling this problem. Interest in sport is not universal, and additional facilities might simply attract the already fit, not those who most need them. Physical activity could be encouraged relatively cheaply, for example by installing exercise equipment in parks, as my local council has done. This has the added benefit that parents and children often use them together just for fun, which develops a positive attitude to exercise at an early age.
As well as physical activity, high tax penalties could be imposed on high-fat food products, tobacco and alcohol, as excessive consumption of any of these contributes to poor health. Even improving public transport would help: it takes longer to walk to the bus stop than to the car.
In my opinion, focusing on sports facilities is too narrow an approach and would not have the desired results. People should be encouraged not only to be more physically active but also to adopt a healthier lifestyle in general.
这篇作文在写的时候采用了五段式的写作方式。作者在开头的时候引出了话题，然后在第2段中先分析了增加sports center 的好处。在第3段和第4段中，作者又很快转折到其它有用的方法，比如在公园中安装运动设施或者对让人们发胖的产品施加高的税收惩罚。结尾段中，作者又总结了个人的观点，指出提高人们健康的方法其实有很多。
