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.

When we talk of plants, most of us will think of things that grow from the ground and have green leaves, but there are plants that do not look or act like other plants. Some of these belong to a special class of plants called fungi.
Fungi may appear almost everywhere. ①They commonly grow in wet places where they can get food and water easily. Because fungi do not have green leaves to make their own food, fungi must take their food from animals, other plants or water. Some fungi live on dead or rotting wood, while others grow on living trees or in dirt or moss(苔藓). Mushrooms(蘑菇) are the best-known fungi.
There are many kinds of mushrooms appearing in all shapes and sizes. For example, cauliflower mushrooms are found in forests from July to October. They can grow to be as heavy as fifty pounds! They grow at the foot of trees. Squirrel’s bread(松茸) is another kind of wild mushroom. Its appearance and use can explain its name. These fungi look like small golden cakes. Squirrels can easily eat them or carry them off to their hole to eat later.
③食品店里的蘑菇是人们精心种植的,可安全食用。People are warned never to touch or taste wild mushrooms, because some of them are deadly. Even less dangerous ones can still make a person very sick.
