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," says Pownall.
 
 
According to WittFitt, 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
 
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 has been a lot of rain in California recently. Villagers and leaders there begin to be worried because they have found two birds died from a disease, West Nile Virus(
 
病毒
).
 
 
 
    West Nile Virus is carried by mosquitoes(
 
蚊子
).The symptoms(

) are just like the flu. However, it can cause dangerous brain problems. When it rains a lot, it will leave a lot of water in ponds and trees. These places are good for mosquitoes. Mosquitoes lay their eggs in the water. Warm weather will help the mosquito eggs to develop and then the number is increasing. Birds eat the mosquitoes and get sick. People can get the disease if they are bitten
 
by mosquitoes with West Nile Virus.

    There have been many great inventions or things that changed the way we live. The first great invention was the one that is still very important today——the wheel. This made it easier to carry heavy things and to travel long distance.
 
   
 
For hundreds of years after that there were few inventions that as much effect as the wheel. Then in the early 1800s the world started to change. There was little unknown land left in the world. People didn’t have to explore much any more. They began to work instead to make life better.
 
   
 
In the second half of the 19th century many great inventions were made. Among them were the camera, the light and the radio. These all play a big part in our daily life today.
 
   
 
The first part of the 20th century saw more great inventions. The helicopter in 1909, movies with sound in 1926, the computer in 1928, jet planes in 1930. This was also a time when a new material was first made. Nylon came out in 1935. It changed the kind of clothes people wore.
 
   
 
The middle part of the 20th century brought new ways to help people get over diseases. They worked very well. They made people healthier and allowed them to live longer. By the 1960s most people could expect to live to be at least 60.
 
   
 
By this time most people in developed countries had a very good life. Of course new inventions continued to be made. But man now had a desire to explore again. The earth was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then United States took a step. Since then other countries, including China and Japan, have made their own steps into space.
 
   
 
In 1969 man took his biggest step away from earth. Americans first walked on the moon. This is certainly just a beginning, though. New inventions will some day allow us to do things we have never yet dreamed of.
