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 don’t 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.
【亮点点评】
[1]“尤其”，表示强调。
[2]“成为主力军”。
[3]过渡衔接词语，使文章条理清晰、衔接紧密。
[4]用于引出对危害或负面影响的阐述。
