Are you carrying too much on your back at school? You’re not alone. Back experts in the United States are worried that young students are having back and neck problems as a result of carrying too much in their backpacks (schoolbags)
“It hurts my back when I run,”said Oberlin Reyes, a student in Virginia. “It’s hard to go up the stairs with my backpack,because it’s too heavy,”
Oberlin was among students whose backpacks were weighed for a week in a recent study.
They had regular backpacks with two straps(带子)to carry them, but a number of students with heavy loads had switched to rolling backpacks (which have wheels and can roll on the ground).
Shirley Park, whose backpack weighed 10 kilograms,said she changed to a rolling backpack because she was starting to have back  pain.
How much is too much?Experts say students should carry no more than 10 to 15 percent of their own body weight.
A few students had one suggestion to lighten the load:less homework.
P.S.( 附)Doctor’s suggestion:
1 Lighten the load. Clean out binders(活页材料)and take home only the books you need that night.
2 Wide straps are better. They send out the weight over your shoulders more evenly(均匀)。 And be sure to wear both straps rather than hanging the pack over one shoulder.
3. Pack smart. The heavier things should be packed closed to the back.
4.Bend both knees when you pich up the pack ,and don’t just bend over  at the waist.(腰)

“Life is speeding up. Everyone is getting unwell.”
This may sound like something someone would say today. But in fact, an unknown person who lived in Rome in AD(公元) 53 wrote it.
We all love new inventions. They are exciting, amazing and can even change our lives. But have all these developments really improved the quality of our lives?
Picture this. You’re rushing to finish your homework on the computer. Your mobile phone rings, a QQ message from your friend appears on the screen, the noise from the television is getting louder and louder. Suddenly the computer goes blank and you lose all your work. Now you have to stay up all night to get it done. How happy do you feel?
Inventions have speeded up our lives so much that they often leave up feeling stressed and tired. Why do you think people who live far away from noisy cities, who have no telephones, no cars, not even any electricity(电) often seem to be happier? Perhaps because they live simpler lives.
One family in the UK went “back in time” to see what life was like without all the inventions we have today. The grandparents, with their daughter, and grandsons Benjamin, 10 and Thomas, 7, spent nine weeks in a 1940s house. They had no washing machine, microwave(微波炉), computer or mobile phones.
The grandmother, Lyn, said, “The more things you have, the more difficult life becomes.” The boys said they fought less. Probably, they said, because there was less to fight over, such as their computer. Benjamin also noticed that his grandmother had changed from being a “trendy(赶时髦的), beer-drinking granny”, to one who cooked things.

In 1926, a Frenchman named Niepce needed pictures for his business. But he was not a good artist. So he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photo. The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything clearly, even the smallest thing. This kind of photo was called a Daguerreotype(银版照相). Soon other people began to use Daguerre’s way. Travelers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains. In about 1840, photography was developed. Then photographers could take picture of people and moving things. That was not simple. The photographers had to carry a lot of film and other machines. But this did not stop them, for example, some in the US worked so hard. Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike(栩栩如生的). Photography also became one kind of art by the end of the 19th century.
