15．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 get up the stairs with my backpack，because it's too heavy．"
     Oberlin is 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：
     ①Lighten the load．Clean out binders （活页材料） and take home only the books you need that night．
     ②Wide 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．
     ③Pack smart．The heavier things should be packed closed to the back
     ④Bend both knees when you pick up the pack，and don't just bend over at the waist （腰）．
