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).
 51"D"is the main idea of the text.
A.The problem of backpacks is worth studying
B.The problem made by heavy backpacks
C.What is the best backpack for a student

52.According to Oberlin Reyes and Shirley Park,we knowA
A.students have to do too much homework

One day,there came a sound from the radio.This sound brought the piece of news:a heavy storm was coming.William Tomic,principal(校长)of the school,asked teachers to bring children indoors and put them in a safe place at once.

19.Because deaf people cannot hear,they have special ways of communicating.One way is lip (嘴唇.reading.With training,people can learn to understand what someone is saying by looking at the(81)mouth of the speaker.Speaking is possible but difficult for the deaf.Because they cannot hear their own voices,it takes a lot of training to be able to make the(82)clear sounds,and not all deaf people can get this skill.The way of communicating is sign language,which is the most useful in real life.
In many ways,sign language is (83)similar to spoken languages though actually there is some difference.The"words"of sign language are its signs.The signs are formed with movements of the hands,face and body.Each sign has a different meaning.Signs are mixed up to form sentences.The basic sign language is hand signs that take the place of letters.The signs,which are put together,can (84)express the same thoughts,feelings and so on as a spoken language.And just as different countries usually speak different languages,most countries have their own variation (变化)of sign language.
In addition to knowing sign language,it is also helpful to know(85)something about how deaf people communicate.Hand waving or hitting a table or the floor to get someone's attention is fine.Also,lots of eye (86)contact is necessary.Information can be read from their eyes.Lastly,it is good to remember that most deaf people(87)seldom think of themselves different from other people,and you don't have to,either!
