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)

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 about young students’ back and neck because their school bags are too heavy for them.
“It’s hard for me to go upstairs with my heavy bag,” said Rick Hammond, an ll-year-old student in the USA.
Rick is among students who have school bags with two straps(带子),and many other students choose rolling(有滚轮的) bags.
But even with rolling bags ,getting upstairs is still a problem for children .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 carry no more than 10% of their weight and older children shouldn’t stay with over 15% , because their bodies are still growing.
Teachers and parents should do some things to help children. And the best answer is to have less homework!

     Thank you, Mr. Morley, for your kind introduction. It was very nice of you to speak of me like that. While I was listening, I had trouble believing that I was the man you were talking about.

     My thanks go out to all of you for being here at this dinner. I look around and say to myself, "These people are my friends." And you know how good it is to be among friends.

     Seven years ago, I became the tennis coach (教练) at this school. I can remember arriving here as if it were yesterday. When ! started coaching, we only had a small team then, just three boys and two girls, and only one tennis court. So my first job was to increase the team. At the end of the first year, we had ten boys and six girls. And it seems like the team keeps getting stronger every year.

     I've been lucky to have some really good players to coach. Coaches love good players. Some great players from our school over the past years include Herbert Bradbury, Christopher Stanton and Emma Austen, all champions (冠军) during the years they played.

     Among the players on our team now is Arthur Burney, perhaps the best of them all. I'm sure you all join with me in wishing him good luck as he leaves for Capetown next week. He's our first student to enter the Capetown Junior International Tennis Tournament, where he will play against some of the best young tennis players in the world. Good luck, Ace!

     The time has come for me, however, to make a change. Recent health problems have made it difficult for me to continue coaching.

     I must say, I'm looking forward to my retirement (退休) with mixed feelings. I'm certainly ready for a long rest, but I'm a bit worried about what I'll do with all my spare time. You might find me coming down to watch the games from time to time. If you can still remember me, you might say hello.

     Thank you everyone. I'll miss you all.
