Dear sir
I‘m writing to talk about the problems of food safety nowadays
Eating Safely Food safety is very important to us. How can we make food safe? Here’s some advice. First, we shouldn’t go out to eat fast food often. At the restaurant there is also some food that isn’t safe, such as unhealthy oil. Second, we should make food clean before cooking. Remember to boil food. Third, we should buy and eat food carefully. If the food is in bags, we should read instructions and dates carefully. Make sure the food is safe.
the problem of food security Nowadays, there is an increasing number of problem in the food security aspect(方面)， such as the swill-cooked dirty oil and the milk scandal. Because of last year's Sanlun scandal, food safety become a hot topic and how can we prevent another milk scandal? In my opinion, it is the lack of credit that lead to the serious problem of food security. We should strengthen the propaganda and education so that we can enhance people's safety consciousness and change their moral idea. Besides, we should strengthen the legal system and the supervision of food security .Only in this way can we live a healthier and happier life.
食物和健康(Food And Health)
As we know,good health is more important than wealth.Food gives us energy,so we must have enough food to keep healthy.we should eat more fruit and vegetables and less meat,and we also must have right kinds of food.A cup of milk a day can help make us healthy as well.Different foods help us in different ways,if we eat too little or too much,or if we choose the wrong food,we may become sick,so we must have meals three times every day on time,too. It's necessary for us to have healthy eating habits.
Health is more important than wealth. Good health enables us to enjoy our life and achieve what we hope for in our career. On the contrary, poor health leads to nothing. How can we keep healthy Here is some advice. Firstly, it is very important for us to take more fruits and vegetables because they provide vitamins, and we have to keep a
balanced diet. So we should avoid food with lots of sugar and fat/which is rich in sugar and fat. Secondly, we'd better exercise every day to make our bodies strong. Besides, we
have to avoid too much work pressure. Finally, we have to get rid of those bad habits that damage our health, such as drinking and smoking.
In conclusion, if we stick to the advice given above, we will lead a healthy life
Today, more and more people are in poor health. If we want to keep healthy we should healthy diet.
First, we should have a balanced diet.Though we may not like eating vegetables, but the vegetables have a lot of nutrition. They are very good for our health. Second, we'd better eat regular meals. We need to eat breakfast, lunch, and dinner every day. Because regular meals throughout the day can give us enough energy to carry out our daily activities.
Third, we should get away from fast food, for it may cause a lot of disease.

一篇关于食品安全的文章 (2008-11-28 17:32:48)
标签：杂谈
刚写了一篇关于食品安全的文章，写的字数比较多，准备不同考试的同学按需择用吧。 there is no denying the fact that food safety is a grave problem with which this country is confronted. a joke goes that everyone who can survive in china can survive in any other part of the world, which means that the test one faces in china in terms of food safety is the gravest in the world. the most notable instance might be the notorious san lu milk powder scandal which has drawn considerable publicity in the past months. causing kidney stones among thousands of infants and deaths of some of them, the milk powder containing overdose melamine is but one example of numerous substandard food products in this country. while blaming those wrongdoers and sympathizing those victims, we must examine the fundamental causes of the problem and work out effective solutions.
though many other countries, even countries like the u.s. and japan, have also experienced food safety crises in some periods of their development, maybe none of them has witnessed food safety problems on such a large scale and during such a long period of time. actually, problematic food products had been with us for quite a long time before we realized them and almost no single food or even drink can be claimed absolutely safe. flours may contain too much chemicals like brightener that can turn them into the desirable color; meat might have been produced by animals that have consumed chemicals to add to the red part of meat; vegetables may have too much remnants of pesticides on their leaves; even milk and other beverages may have in them poisonous chemicals to make them smell flagrant and tasty.
why are substandard food
we needn’t go far to see the disastrous consequences of the food safety crisis. not only are people’s health and lives directly threatened, but tremendous amounts of resources are wasted. the thousands of tons of milk powder burned to ashes is a case in point. furthermore, an atmosphere of dishonesty and disbelief will permeate the entire society, which will not only hinder thedevelopment of economy but will ruin the nation spiritually.
