Passage 2
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).（273 words）

Oh dear! I've just broken a window.
-____________.
A.Great
B.Never mind
C.That's fine
D. Not at all
这道题应选择B选项.一定注意,有些人会选成D.
B选项是别在意,不要放在心上的意思；而D选项是一点也不,没关系、不客气等含义.在这里使用不符合题意.
阅读理解
1、选C.What is the best backpack for a student .意思是什么样的背包更适合于学生.从文章的后部分可以看出作者已经给出了答案,lighten the load、wide straps、pack smart、bend both knees等等.
2、选C.意思是没有轮子的背包对学生来说没有好处.
选项B语义上有问题.从这两名学生的说话中能够看得出,带轮子的背包可以解决负重问题.
祝好!
