题目大意：
越来越多人体重肥胖。有人说提高高脂肪食品的价格可以缓解肥胖问题。同意反对？
思路解析：
这是一道观点类大作文，聊得是肥胖问题如何解决。题目提出了一个观点，提高fattening food的价格能够解决人们的肥胖问题。那么，我们要思考两件事情，fattening food 是不是导致肥胖的原因，其次再来看提高价格是否有效解决。先要知道的是，导致人们肥胖的原因其实有很多，饮食不健康、缺乏运动、身体代谢差等都可能会导致肥胖。其中fattening food 因为高热量、高脂肪等因素，如果长期摄入确实容易导致身体肥胖。这一点是没有疑问的。但是许多人明知道这些食物不健康的人为什么还会食用？除了好吃外，还因为这些食物便宜。有一些人他们吃不起更贵的健康的食物，只能更多的吃这些垃圾食品。因此，单纯提高fattening food的价格并不能解决肥胖问题。一是因为肥胖问题本来就是由多种因素产生，有的人可能代谢差以及不爱运动，哪怕他吃的比较健康也会肥胖。二是对于那些有钱人来说，再怎么提高价格也不会影响他们是否食用这类食物，但对于贫穷的人来说，这会增加他们的生活成本和负担，只要这些食物比健康食物便宜，他们依然会食用且生活成本比以前更高，或是他们会去寻找替代的可能有其他问题的便宜食物来替代。
范文示例：
Given that obesity has become an impending trend today, it is assumed that a hike in the prices of fattening foods will curb the problem. However, I would say it is oversimplified to pin the hope on inflating the prices of junk food since the approach does not do much to encourage a healthy diet.
Indeed, it is not difficult to understand why increasing the prices of fattening food is considered effective to constrain the trend towards overweight. Those who think in this way opt to attribute the conundrum to people’s unhealthy diet: the impressionable majority are inevitably susceptible to the low prices when shopping for groceries, while such foods tend to contain excessive sugar or fat. Based on this understanding, some people convict that by inflating costs of fattening foods can compel consumers to buy more healthy products.
Plausible thought the above reasoning seems, I would say that to make junk foods less affordable does not have much of a role to play in improving public health. The overriding concern here is: those championing the claim in question reach their conclusion based on an erroneous causal connection between the problem and its reason – what exactly results in people’s bias for junk foods is their economic plight: those living in poverty are intimidated by the prohibitive prices of quality foods (i.e., fresh vegetables, fruits, etc.) and turn to less expensive counterparts. With this in mind, to increase fattening foods affordability will not change reality on the ground, whereas other options may be more practical, with one measure being governmental subsidy for healthy diet among less well-off class.
From what has been discussed, I would say that inflating fattening foods will improve people’s healthy diet, while a more practical solution is to make quality food more affordable.
