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!

Are you carrying too much on your back at school? You’re not alone. Back experts(专家) in the USA are worried about that young students are having back and neck problems because they are carrying too much in their backpacks .

“It hurts my back when I run,” said Ebelin Reyes, a student in Virginia. “It’s hard to get up the stairs with my backpack because it’s too heavy.” Students have to carry heavy backpacks on their backs for a whole week’s study. Ebelin is one of them. They have   regular(固定的)backpacks with two straps(带子) to carry them, but a number of students with heavy loads(负担) have switched to rolling backpacks. The backpacks have wheels and can roll on the ground. Shirley Park’s backpack weighs 10 kilos, and she said, “I’ll change to a rolling backpack because I am starting to have back pain.”

How much is too much? Experts say that students should carry no more than 10% to 15% of their own body weight. A few students have had a good idea to lighten(减轻) the load: less homework.

Doctor’s suggestions:

Lighten the load. Take home only the books the students need that day.

(2) Wide straps are better. They can send out weight over your shoulders (肩)and be sure to wear backpacks with two straps.

(3) The heaviest things should be packed closest to the back.

(4) Bend(弯曲) both knees when you pick up the pack, don’t just bend over the waist(腰).
