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. (附言) 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 pick up the pack, and don't just bend over at the waist (腰). 翻译

解题思路： 如下
解题过程：
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). 在学校你背着太多的书本吗？不单单你这样。美国的背部专家担心年轻的学生们有背部和颈部的问题，这是他们在书包里有太多的书本的一个结果。
"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." 佛吉尼亚的一个学生Oberlin Reyes说，“当我跑时，它（书包）弄疼我的后背”。“很难背着我的书包上楼梯，因为它太重了。”
Oberlin is among students whose backpacks were weighed for a week in a recent study.
在最近的一项研究中，许多学生的书包被称重量一周，Oberlin就是其中的一个学生。
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). 他们用正规的有两个带子的书包来装书，但是有许多书本要带的很多学生都开始使用可以滚动的书包（书包上按有轮子可以在地上滚动）。
Shirley Park, whose backpack weighed 10 kilograms, said she changed to a rolling backpack because she was starting to have back pain. Shirley Park的书包重10公斤，她说她把书包换成了一个可以滚动的书包，因为她开始后背疼了。
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.
多重才是太重了呢？专家说学生背的书包重量不应超过学生体重的10%-15%。少部分学生有一个建议是减负：少留作业。
P.S. (附言) Doctor's suggestion: 医生的建议：
① Lighten the load. Clean out binders (活页材料) and take home only the books you need that night. 减轻负担。清理活页材料，只把那天晚上你需要的书带回家。
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.
宽书包带更好一些。他们更均匀的分散了你肩膀上的重量。一定要两个肩膀都背书包带，而不是把书包放在一个肩膀上。
③ Pack smart. The heavier things should be packed closed to the back.
聪明的装书包。比较重的东西装书包时应该靠近背部。 ④ Bend both knees when you pick up the pack, and don't just bend over at the waist (腰). 当你背书包时，要弯曲双膝，不要只弯腰。
