On Dieting
Nowadays more and more people are beginning to go on a diet. Some people are concerned with their health, and they go on a diet in order to lose unwanted weight. But still others, [1]especially the young women, are paying too much attention to their outward appearance. They [2]become the leading numbers who go on a diet.
[3]However, dieting might [4]bring great negative effects on people. [3]For one thing, quite a lot of people dont really need dieting to keep health, and they diet just because they want to keep slim. For them, dieting [5]not only is useless but also might damage their health. [3]For another, some people lack enough knowledge on how to diet scientifically. [3]As a result, they are likely to suffer from malnutrition.
[6]Considering the serious damage of unhealthy dieting, we should be cautious in dieting. [3]In my opinion, dieting,[7]for whatever reasons, needs professional guidance. [8]Only with right guidance can dieting work [9]as we expect.
现在越来越多人在节食。一些人担心自己的健康，所以通过节食来减掉超过的体重。但也有一些人，特别是女人，对她们外表太在意了。她们成为了节食人群的主导者。
但是，节食会对人们带来很多负面影响。一方面，大部分人都不需要真的节食来保持健康，他们只是想保持苗条身材。对于他们来说，节食不仅没有用反而对他们的健康造成伤害。另一方面，一些人对怎么科学的节食不是很了解。结果，他们遭受了营养不良。
考虑到节食的坏处，我们在节食的时候一定要小心。我认为不管是因为什么原因节食，都需要专业的指导，只有正确的知道节食才会有效果。
