Sitting on exercise balls brings more than a smile to students and teachers.
Some fourth-graders at Conrad Weiser West Elementary School in Womelsdorf love their new chairs-—probably because they're not really chairs at all.
The kids are sitting on the air-filled balls. But different from those just for exercise, these have small legs that keep them from rolling. Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By using exercise balls instead of common chairs, teachers find students' posture(姿势) and attention improved.
Dotti Pownall, a fifth-grader teacher in West Virginia, has been using balls as chairs since December 2008. "The students love them." she says. Pownall took a survey of her students. She found that 80 percent, thought sitting on the balls helped them concentrate(专注) better:
"Besides, they’re fun,b" says Pownall.
According to WittFitt,b a company that has sold balls to more than 200 schools, they can improve kids' posture and classroom behavior.
Exercise ball chairs are getting popular in classrooms, from preschool to college. Some adults (成人) even use them at work.
Lisa Witt felt so strongly about the use of balls as chairs that she started WittFitt. She said the company not only encourages the use of balls but also educates teachers and students on how to use them. "We sell balls in 24 states in America, three provinces in Canada and Japan." says Witt.

There are few families in the United States that do not have either a radio or television set. Both of them have become a necessary part of our daily life, keeping us filled with the news of the day, teaching us in many fields of interest, and making us happy with singing, dancing and acting.
Marconl, the Italian inventor, who gave us the radio, probably didn’t know how much his great invention would have done for the world in the years to come. Radio had, perhaps done as much as any other communication tool. Things of the world can be reported to people everywhere a few seconds after they happen. Travelers in or out of–the–way places, ships at sea even astronauts round the earth are able to keep in touch with each other by radio.
Television is another important invention. It lets us see as well as hear the actor. Since its appearance, TV has done a great deal in the daily life of people everywhere. Many programs are now televised in color.
Perhaps the most modern invention is “Telstar”, a “star” moving round the earth. It makes it possible for the people all over the world to be closer than ever before. Now a family in Chicago can watch on TV a motor–car race in Italy, a table tennis competition in Beijing or a volleyball match in Japan as these events are actually happening!

Thomas Edison was a great American inventor. He was born to a poor family in 1847. His mother taught him at home. He often observed things carefully and he made over 1,300 inventions during his life time. He was often said to be the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius. “There is no such thing as genius,” Edison said. He also said that what people called genius was mostly hard work. But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them.

Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure.

Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. “Work, ” he answered back, “discovering the secrets of nature and using them to make men happier.” He said he had enough inventions in his mind to give him another 100 years of work.
