    Most drinks stating that they are fruit-flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.

    “Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be non-existent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. It will increase profits, and consumers won't always realize they are being tricked.”

    Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry-flavored products sold in stores. Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.

    Let's take jam as an example. Some strawberry-flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.

    Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. Unfortunatly, it is also legal and widespread,” Tokelove said. “It's time to take measures to protect the consumers' rights.”

A. The products which contain real fruit are popular with people.

B. Even products advertised as more natural often contained no fruit.

C. They found that about 60 percent of them didn't contain any fruit at all.

D. If companies can cut their costs by using flavoring, they are likely to do so.

E. It is important and necessary to demand a small amount of flavoring in the products.

F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.

G. The Food Commission suggested all flavors used in a product should be listed on the packaging.

    Last weekend's concert, organized and performing by the students of the Welsh Community College, was great success. The student had been practicing for months for the concert. They were excited that when they heard Gareth Jones was coming to present the prizes. Over 100 young performers play a mixture of jazz, classical or folk music. One of the highlights were 14-year-old Megan Evans, playing traditional Welsh folk songs. The concert ended with a very loud pop tune and anyone in the hall stood up and danced with the music. It was a magically atmosphere and a wonderful evening.
