Where does your food come from? How is it made? These days, many people worry about food safety. But food safety is not a new worry. In 1906, Upton Sinclair wrote the Jungle. The book is the story of a poor family in Chicago. It is also about the dangerous ways that food was prepared. People were so worried that the U. S. started testing food.

These days, most food in the world is safe. Laws control where food comes from. They also control how food is managed and prepared. Laws are important. But it’s more important to make sure the rules are followed. A good food safety system（系统）keeps people safe. It also helps them eat healthy food. Labels（标签）on food give people important information. Then they can make good choices about their food.

Although food safety systems usually work, there can be problems. Sometimes mistakes are made. For example, a truck might carry eggs and then ice cream. The ice cream could make people sick when the truck isn’t cleaned before carrying it. Other problems are not mistakes. Sometimes companies break rules to make more money. When this happens, people don’t know if D their food is safe.

As we all know, food is closely related to our daily life. We should take action to make food safer.

Every school has its own set of rules to keep students disciplined (守纪律的). The rules change from one school to another. Some schools are much stricter than others. There are also some rules that look strange or funny to us. Here are some funny school rules:

Tough(严格的) Japanese rules. Most schools ask that students wear uniforms, such as sports suits or skirts. But many Japanese schools even regulate (规定) the color of underwear (内衣)! They also ask the girls to fold their white socks in a certain way and the boys to shave (剃) their heads. 3.Other Japanese schools tell students that they may not hang out, go to the movies, leave home after sunset or play video games without permission (许可) from the school.

Different shoes in the US. For safety at some US schools, students must have a pair of indoor shoes to change at school every day. 4. This makes sure students won’t fall over on the slippery(湿滑的) floors and keeps the schools clean. Gum (口香糖) chewing is not allowed in many US school buildings, as it is difficult to clean the gum up. And if students chew gum in class, they may not focus on their study.

No strange hair in the UK. Strange hairstyles are not allowed in some British schools. But they might allow students to wear certain hairstyles during the World Cup years. Two students cut their hair into a special design during the 2002 World Cup. But they were not accepted by their school after that because the school said the rules had changed since then.
