In England, some food companies across the whole country have been told to carry out urgent (紧急的) tests on all beef products. Do you know why? That’s because some food companies used horsemeat to make beef products.

         There are some examples about the horsemeat matter. In January, 2013, in a number of UK supermarkets, frozen hamburgers were found to have traces of horsemeat in them. Some frozen beef products made by food company FINDUS were found to contain horsemeat. All of the beef products made by this company have been removed from sale.

         The government said that there’s nothing to suggest any health risk from the products. Food minister David Heath said people should not throw away frozen meat products and carry on eating meat. The government will tell people not to eat meat if the meat is not safe.

         Food safety has been an important matter all over the world. More and more countries plan to take some useful measures to ensure the safety of food.

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!
Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
"We’ve learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It’s hard to get a clear result.
Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.
The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
"It’s our first scientific journey, Huang said, "But it makes me want to try harder."

Swimming is very popular in summer. People like swimming in summer because water makes people feel cool. If you like swimming and swim in a wrong place, it may not be safe.

They often think they swim so well that nothing can happen to them in rivers. It’s summer now. If you go swimming, don’t forget that some good swimmers have died in rivers.

People usually hate mice, but people almost all over the world like one mouse-- the famous Mickey Mouse.

About eighty years ago, most films had no sounds. A man called Walt Disney made a cartoon mouse. The cartoon mouse could talk in these films. He made his mouse become a good friend of both young people and old people. Children liked to see their lovely friend, because he brought happiness to them.

Mickey is a clean mouse right from the beginning. Maybe this is why people love Mickey Mouse very much. In his early life, Mickey did some wrong things. People were very angry. They wrote to Disney and said they didn't want Mickey to do the wrong things. Because there were some things that Mickey could not do. Disney made a new animal called Donald Duck. He also made a dog, Pluto. This dog does some foolish (愚蠢) and wrong things wherever he goes. Now, our Mickey Mouse is more interesting as well. He is known as a star of beauty and wisdom (智慧). He has friends in almost every country.
