Are you carrying too much on your back at school? I’m sure lots of children of your age will, say "Yes". Not only the students in China have this problem, but children in the United States also have heavy school bags.
Doctors are starting to worry that younger and younger students are having back and neck problems as a result of schools bags being too heavy for them.
"It’s hard for me to go upstairs with my bag because it’s so heavy, "said Rick Hammond, an 11-year-old student in the US.
Rick is among students who have common school bags with two straps(带子) to carry them, but many other students choose rolling(有滚轮的)bags.
But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.
But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight(重量).
Scott Bautch, a back doctor, said children under Grade 4 should stay with 10 % . But it is also important that older children don’t stay with over 15 %, because their bodies are still growing. "Children are losing their balance(平衡) and falling down with their school bags, "he said.
Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.
One of the best answers is, as some children said, to have no homework at all!

Long long ago, a king had a big rock placed in the middle of a very busy road. Then he hid nearby to see if anyone would move the rock out of the way to make it convenient for others. Some of the king’s wealthiest supporters came past and simply walked around it. Many others complained about the rock and some blamed the king for the problem. To the king’s surprise, no one did anything about moving it out of the way.
Finally, a poor farmer came along, carrying a load of old vegetables. When he saw the rock, he put down his load, and tried to move the heavy rock to the side of the road. No one stopped to help him. Many laughed at him and made jokes as they walked past. Finally, after much pushing and straining, and with no help , the farmer managed(设法) to get the rock to the side of the road. As he bent down to pick up his vegetables, he noticed a small bag lying in the road, exactly where the rock had been. There was a lot of money and a note in the bag. The note was from the king saying that the money was for the person who moved the rock out of the way.
Taking responsibility(责任) is about solving hard problems. The farmer takes responsibility when no one else is prepared to. It does not always mean that you will get an instant reward, but it is a value that builds up a community, and makes life better for all of us.
