Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are often believed to be the cause of a number of things from poor eyesight and headaches to house fires. There's even one theory that mobile phones should be responsible for the disappearance of bees!
The theory is that the radiation (辐射) given off by mobile phones does great harm to bees' navigation systems (导航系统). Bees have built-in system a bit like GPS and this helps them find their way back to their hives. But recently, thousands of bees have failed to find their way home. It is believed they are dying far from their hives.
The problem was first noticed by beekeepers in America and is a lot more serious than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated by them. Without bees, the crops can't continue to grow. Many beekeepers in Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, London beekeeper, said to the reporter, "My business is becoming worse. Twenty-nine of my forty hives are now empty."
Nobody knows for sure whether the theory is true or not, but it's a fact that bees are disappearing in very large numbers. And we can't manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! If the mobile phone theory is correct, we need to do something about it right now—before it's too late.

A yearbook is a tradition of high school life in the United States. The book contains (包含) the name, photo, and signature (签名) of each student in your final year, so that you can remember who you went to school with. A 15-year-old girl Catherine Cook and her brother David wanted more than this. They thought, "Why not have a yearbook online? You could learn about people's music tastes, the movies they like, and so on."
Catherine thought of the name—myYearbook.com, and the logo (图标). To advertise the site. Catherine and David wore T-shirts with the site logo to school and soon hundreds of their schoolmates became users of the site. She spent many evenings talking on the phone to programmers in India, and collecting ideas from her schoolmates. Then her older brother Geoff came up with the money to start up the website.
My Yearbook users can join in the fun by sending messages and "collecting" friends. They can watch the same videos from films and TV programs, and share music, photos, homework and study guides. Some teens feel they can't make friends more easily online. Chatting online helps some shy people not to feel left out.
Users can also make "Lunch Money" by doing activities on the site. They can then spend their Lunch Money on gifts, or donate (捐赠) it to charities. They have saved 0.3 km2of rainforest, cleaned up million kg of CO2, sent 22,000 books to Africa, and bought 20,000 kg of rice for people without enough food.
Running the website did not stop Catherine and David from finishing their schoolwork successfully, and going on to university where they still spent 50 hours a week on the site.
