Turns out，you're not just what you eat—you're also where you eat．

  Researchers found out that people had double the number of calories(卡路里)when standing in a messy kitchen compared to when they stood in an orderly one．

    The researchers had 98 women spend to minutes in kitchens，under the guise of (以……为幌子)asking them to wait for someone．Half of the women stood in a messy kitchen，with piles of newspapers，dirty dishes and a ringing phone．The other half of the women waited in a clean kitchen．

    Both kitchens had bowls of biscuits and carrots．Each woman in the messy kitchen ate twice as many cookies compared to those in the clean kitchen．

    Why did this happen?

    “Being in a messy environment and feeling out of control is bad for diets，''Lenny Vartanian，one of the researchers，said．“It seems to lead people to think，‘Everything else is out of control,so why shouldn't I be?'''

    The study's size was small，but the findings prove something we know all too well：Stress(压力)is bad for you．Stress often causes people to overeat．Beyond weight gain，too much stress can also increase a person's heart rate，and lead to painful conditions like headaches．

    While there are many ways to manage stress．including listening to music and exercising，this study shows that there are easy and quick things you can do to find calm．The next time you don't want to tidy up the kitchen，remember that the exercise will help you a lot in so many ways．

    You've got plenty of emails from your mom, and maybe even a few from dear old grandma. But have you ever received a message from a river?

    Now, Ireland's River Lee is sending out much information, thanks to wireless(无线的) technology. In a program called the DEPLOY project, scientists have put some sensors(传感器) in rivers that can find pollution levels.

    Instead of asking scientists to collect water samples several times a day, the government can now examine pollution levels in the water, and find out if there is anything polluted entering the river. This makes it much easier for scientists to protect the environment, since problems can be discovered before a serious pollution accident really happens.

    People in the area can also receive free reports from the river, so that they can find out whether the water is safe for swimming or boating on a certain day. And people can also know if the water is clear enough for them to drink and use.

    The DEPLOY project has not only started in Ireland, also the same programs have started in thousands of places around the U.S. Now you live in a world in which you could receive information with your mobile phone about environment. The technology should help to make us know more about the pollution that surrounds us—which just might get us all a little more involved with trying to clean up our world.

    Canada Geese are large blue and white birds. When autumn comes, they have to fly south where the weather is warmer. The winters are so cold in Canada that the birds will die if they stay there.

Last spring, Bill Lishman found sixteen young Canada Geese on his farm. They had lost their parents. Bill thought, "These young birds won't know what to do in the autumn." He had a small plane and he decided to teach the birds to fly by following him. All through the summer, he went on short trips in his plane and the young geese flew after him.

When the cold weather arrived in the autumn, Bill flew to Virginia in the United States——600 miles South of his home in Canada. The geese followed him all the way. Bill left the geese in Virginia and he returned home.

    This spring, Bill was waiting for the birds to come back. They didn't arrive, so Bill flew to Virginia to get them. He looked for them for two weeks but he couldn't find them. When he arrived back home, he found the geese waiting for him. They had found their way home without him!

    The Internet joins millions of computers all over the world,and today it is used by people all over the world.It was invented in the 1960s in the USA.The American government needed a network of computers for its army.Then in the 1970s scientists and business people also wanted to use the Internet to send and receive messages.For some years,they weren't allowed to use the US network,and when they were allowed to,the messages were in very simple text without photos.

    The World Wide Web was invented by a British scientist named Tim Berners-Lee in 1989.He wanted to send documents to other scientists,so he developed the World Wide Web.This allowed him to send and receive scientific documents with text,drawings and photos(also called multimedia documents).In the 1990s,more and more people began to use the Internet and the World Wide Web.

    So what's the difference between the Internet and the World Wide Web?The Internet is the hardware.It allows us to communicate with other people.The World Wide Web is the software.It allows us to create, see and read multimedia documents.

    The Web is made up of millions of documents called Web pages.These pages are held in computers all over the world.Many people have a favorite website with a number of Web pages on the same subject.

    The email is a way of using your computer to send and receive messages.It's cheaper and quicker to use emails than send normal mails.New users call the normal mail “snail mail” because it's too slow.It took 50 years for 100 million people to listen to the radio.It took 15 years for 100 million people to watch television.By the year 2000, it had taken only about three years for 100 million people to use the Internet.What will happen next on the Internet?
