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 （帶子） 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 （活頁材料） and take home only the books you need that night．
     ②Wide straps are better．They send out the weight over your shoulders more evenly （均勻）．And be sure to
       wear both straps rather than hanging the pack over one shoulder．

5．While travelling，you'll be taking money，license or passport．Or you will buy something expensive to take back home with you and you don't want it to get stolen．Here are some ideas on how to keep your valuables（貴重物品）safe while traveling
Plan ahead of time
Think of what you really need and don't need to take on your trip．Only take the valuables that you must have，not just ones that you would like to have．
Carry your valuables on your person
Something that is small，like cash and credit cards and your passport，can be carried in a money wallet around your neck or in a money belt．This way，your valuables are hidden and right next to you，where you know where they are at all times．Wear clothing that can hide the money belt．
Carry larger valuables in your carry-on bag．
If you can't fit it in your money wallet like some large valuables，you'd better put them somewhere that you will keep touch with them．Your can put them on the plane，so you don't have to worry about the airline losing your bag or someone stealing it from the belt after the flight before you get to it．
Choose a hotel that has the front desk for valuables．
This way，you don't have to worry about housekeeping getting hold of your valuables，or someone stealing your valuables if your room is broken into．If you give the valuables to the front desk to keep for you，choose a time when others are not looking．
