　　快餐食品现在越来越流行，特别是在青少年和儿童中。为什么那么多人喜欢快餐呢?

　　范文一：

　　Fast food becomes more popular now, especially among the teenagers and the children. Why do so many people like fast food?

　　For one thing, it's very fast and convenient. It always serves in no time, so we can either eat it in the restaurant or take it away. For another, because of the different ways of cooking, it looks nice and tastes delicious. What's more, the service and environment is good, so that we can have our dinner in a happy mood.

　　However, in terms of nutrition, it's far from satisfactory. Most fast food is junk food. It contains so much sugar and fat, which makes us put on weight so easily. Since the westerners have the fast food every day, most of them have heavy weights, high blood pressure and bad teeth.

　　Therefore, I suggest that we should eat less fast food but more nutritious dishes.

　　范文二：

　　Fast-food is becoming more and more popular in China, especially among children, teenagers and white-collars.

　　There are several reasons for its popularity. First, it's so convenient that saves a lot of time. Your just need to go into a fast-food restaurant, order your food, and your food is ready in time. Second, you can have many choices, various collocations of food. And you can eat it there or take it away. Third, the environment of fast-food restaurants is both clean and comfortable.

　　However, in terns of nutrition, it is usually not a balanced diet and low in nutritional value. Usually, fast-food is rich in sugar, so that regularly eat fast-food may cause obesity.

　　Fast-food is only a good choice when you are in a hurry and turn to it once in a while. But for people, especially children, eat fast-food as little as possible.
