如今，肥胖已经是很普遍的一个问题了，尤其是在城市人中。由肥胖引起的疾病也长期困扰着人们。所以说，如何对抗肥胖呢？
To fight against obesity, many products or machines about loosing weight have been introduced. However, as far as I am concerned, most products or machines about losing weight would bring some side effects to our body. Therefore, to lose weight, the most important point is to find out the main reason for obesity and take action to lose weight step by step on the basic of complying with out body’s needs. 
关于对抗肥胖，很多产品和机器已经介绍过关于减肥方面的事情。然而，据我所知，大多数产品或者机器减肥都会给我们的身体带来一些副作用。因此，减肥，最重要的一点就是要找出肥胖的主要原因，并采取行动，根据身体的需求一步一步地减肥。
There are several reasons may account for my view on obesity. First, overeating but lacking of doing exercises is a common reason. In particularly, ingesting too much sugar and fat everyday are more easily lead to obesity. Therefore, to lose weight we need to control ourselves from eating too much, especially eating sugar and fat. Besides, we need to take some exercises appropriately. Second, another reason is irregular work and rest. In modern society, sleep too much or work for too long is quite universal. And this irregular work and rest has a great impact for our health and one effect of it may be obesity. Thus, to have a healthy body, we need a regular work and rest. Finally, disease can also account for obesity.
有几个理由可以支持我关于肥胖的看法。首先，暴饮暴食而且缺乏锻炼是最主要的原因。特别是每天摄入过多的糖份和脂肪是很容易导致肥胖的。因此，为了减肥，我们需要控制自己的食量，尤其是吃含糖份和脂肪的食物。此外，我们还需要适当地做一些锻炼。第二，另一个原因是作息不规律。在现代社会，睡眠过多或工作过久是很普遍的。而这种不规律的作息对我们的健康也是有影响的，其中之一可能就是肥胖。因此，要拥有一个健康的身体，我们需要固定的工作和休息。最后，肥胖会引起疾病。只有问医生的帮助才能解决问题。
To sum up, there are various factors accounting for obesity and we need to find out the main one and take action to fight against it. And by the way, we should have awareness of that to fight against obesity needs a lot of time, patience and perseverance.
总之，导致肥胖因素有很多，我们需要找出主要的并采取行动来对抗它。顺便提一下，我们应该意识到对抗肥胖是需要大量的时间，耐心和毅力的。
