Fast food develops fast nowadays because it is economic，convenient and there are kinds of food meet different flavors. It will become more and more popular in the future.

　　However，I don't think eating too much fast food is good for our health. Fast food may cause illness. I admit that fast food is cheap and convenient. You can fill your stomach easily without paying too much. And you don't have to pretend to be graceful when you do want to. Different flavours meet different tastes. You can decide what you want to eat. But every coin has two sides. Fast food also has troubles. The most worrying one is whether fast food is clean or not. In order to gain a greater profit，some snack bars try every means to reduce the cost.Some even adopts illegal means. As is reported on TV and newspaper， many snack bars use some dirty refined oil to cook the meals. It is not easy for the customers to be aware of what they are eating. Usually there will be lots of bacteria in such kind of oil. These bacteria can cause deadly diseases， such as cancer. The customers become victims of the snack bars. Maybe you will ask，"What about KFC or Mc Donald's? The sanity equipments are good in these restaurants." My suggestion is that you'd better eat less. Foods in KFC and Mc Donald's contain much fat. They also cause health problems.Eating too much fried chicken， fried chips，hand burgs and something else may make you fat.

　　In a word，I don't suggest people eat too much fast food.You have much to concern about when you are having fast food. To keep healthy，we have to pay attention to our habit of diet.

　　快餐的发展很快，因为它是经济，方便，有各种各样的食物，满足不同口味。它将在未来变得越来越流行。

　　然而，我不认为吃太多快餐对我们的健康有好处。快餐食品可能导致疾病。我承认快餐很便宜，也很方便。你可以很容易地填满你的肚子而不付出太多的付出。你不必假装优雅，当你想。不同的口味满足不同的口味。你可以决定你要吃什么。但每个硬币都有两面。快餐也有麻烦。最令人担心的是快餐是否干净。为了获得更大的利润，一些小吃店想尽一切办法来降低成本，有的甚至至采取非法手段。正如在电视和报纸上报道的那样，许多快餐店使用一些肮脏的精炼油来烹调食物。顾客不容易知道他们在吃什么。通常会有大量的细菌在这种油。这些细菌会导致致命的疾病，如癌症。顾客成为快餐店的受害者。也许你会问，“肯德基和唐纳德的好吗?在这些餐馆里的卫生设备都很好。”我的建议是你最好少吃点。肯德基和唐纳德的食物中含有大量的脂肪。他们也会导致健康问题。吃太多的炸鸡，炸薯条，一方面城市和其他的东西可能会使你发胖。

　　一句话，我不建议人们吃太多快餐，当你吃快餐的时候，你有很多要关心的问题。为了保持健康，我们必须注意我们的饮食习惯。
