英語四級命題作文：快 餐

Fast Food
　　Fast food is becoming more popular in China, especially among children and teenagers. Today, it's certainly difficult to think of any other single thing that mirrors the fast pace of modern society as powerfully as fast food.
　　There are several reasons for its popularity. First, it is very convenient and saves a lot of time. The trends of modern society seem to all point to one ultimate goal - saving time, and fast food well serves this purpose. Second, its popularity is also attributed to the clean and comfortable environment of fast food restaurants, the excellent service, and the guaranteed quality of food.
　　However, in terms of nutrition, fast food is far from satisfaction. It usually does not compose a balanced diet and doctors suggest that people, especially children, eat fast food as little as possible.
　　Therefore, fast food is only a good choice when you are in a hurry and turn to it once in a while.              (157 words)
