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

　　“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 backpacks with two straps(带子) to carry them, but a number of students with heavy loads (负荷) have switched to rolling backpacks. The backpacks have wheels (轮子) and can roll on the ground. Shirley Park's backpack weighs (重) 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 percent (百分之……) of their own body weigh. A few students have had a good idea to lighten (减轻) the load： less homework .
