Some Schooling on Backpacks
According to the U.S. Consumer Product Safety Commission, 5,900 kids were treated at hospital emergency rooms, clinics, and doctors' offices last year for sprains (扭傷) and strains caused by backpacks. Such injuries are so widespread that more than 70 percent of physicians surveyed by the American Academy of Orthopedic (整形外科的) Surgeons listed backpacks as a potential clinical problem for children.
How do you avoid such problems? Choose bags that have wide, padded straps (有墊的揹帶)and a belt. That will help transfer some of the weight from the back and shoulders to the hips. You should also tighten both straps firmly, so the pack rests about 2 inches above your waist. Also,remember to pack your bag with the heaviest items closest to your back and to bend both knees when you pick it up.
How much should you stuff into your pack? That depends on your size and strength, but a general rule is not to exceed 20 percent of your body weight. So if a child weighsl00 pounds, the backpack and its load should not be more than 20 pounds. One hint: Make frequent trips to your locker (儲物櫃) to exchange books between classes.
Backpacks with wheels let you pull the weight along the ground, but they have problems too.
Many are larger than the average shoulder bag, so students are tempted to carry more than they would in a conventional pack.
Roller bags often don't ftt into a locker. They can also lead to tripping and falls in crowded halls. Whatever you use, 10 Or 15 minutes of stretching and back strengthening is a good idea.

答案與解析
16.A。題幹：去年大約6000個美國孩子因為揹包而受傷。由文章第一段第一句可知，根據統計，去年美國有5900個孩子因為由揹帶書包引起的扭傷及拉傷而接受治療。故題幹表述正確。
17.B。題幹：70%的英國醫生曾經治療過孩子的拉傷和扭傷。文章第一段最後一句中關於此處的表述背景是在美國，而題幹中是英國，並且此處的70%指的是佔接受調查醫生總數中的比例。故題幹描述錯誤。
18.A。題幹：一個帶有寬揹帶墊和腰帶的揹包有利於避免拉傷和扭傷的問題。由文章第二段第二句和第三句可知，選擇一個帶有寬揹帶墊和腰帶的揹包有助於把揹包的一部分重量從肩部和背部轉移分擔到臀部。
19.B。題幹：一個l00磅的`孩子應該背20多磅的揹包。由文章第三段第三句可知，如果一個孩子體重為一百磅，那麼他的揹包負重不應超過20磅。
20.B。題幹：孩子們應該將所有的書放進儲物櫃裡。由文章第三段最後一句可知，文章給出的建議是經常去儲物櫃調換不同科目用的課本，而不是將所有的課本都放入儲物櫃裡。
21.C。題幹：拉桿式書包往往比普通揹包重。文章第四段第二句中提到很多拉桿式書包比普通的帶肩帶揹包要大，但並未提到其重量。
22.A。題幹：l0——15分鐘的鍛鍊可以幫助你承受更多的揹包重量。由文章最有一段最後一句可知，l0到l5分鐘的拉伸和背部強化鍛鍊會是很不錯的方法。故題幹描述正確。
