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 go up the stairs with my backpack,because it’s too heavy,”
Oberlin was 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:
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 pich up the pack ,and don’t just bend over at the waist.(腰)“_________”is the main idea of the text.

A school bus is one that is used to take children to and from school.
In the USA, about 450,000 school buses take more than 25 million children to and from school. The yellow school bus is a US icon (象征). Yellow became the color of school buses in the USA in 1939. Dr. Frank got the good idea. He said it was easy for people to see yellow buses and the black letters on them in early morning or late afternoon. That would make children safer.
There are not many school buses in Britain, and they are not yellow. They have trackers (追踪器) on them, so kids are being tracked while they travel to and from school by bus. The trackers let parents know where the school bus is and whether their kids are on the bus.
Kindergarten (幼儿园) is a difficult time for some kids. It's the first time for them to go away from their parents. To make kids love their school, Japanese kindergartens and schools have colorful buses. The buses can easily make children want to take them--and then, go to school. Even some parents want to take them, too!
School buses are becoming more and more popular in China now. It saves a lot of time for students to take a school bus. It's said that there will be 3,000 yellow school buses on the road by the end of this year in Chongqing.According to Dr. Frank, school buses are safer for the students.

I was quite close to my grandmother, Julia. We lived with her and then she lived with us. She was a very nice person, both kind and patient. She taught me to read and write when I was young and helped me to be interested in stories and poems.
In my mind, my grandmother was a great tailor. She made clothes or toys better than anything you can buy in a shop today. She always made clothes for family and friends.
My grandmother was also a hard worker both at home and at work. I can still remember the difficult time when we were very poor. At that time, my grandmother was already sixty years old but she worked in a hospital for a long time every day--not in the office but doing the cleaning outside and taking care of me at the same time while my mom was at work!

Welcome to Youth Radio, your radio. Here we're proud to introduce three Amazing Kids.
Gina, who is thirteen years old, got first prize in the "Young Cook of the Year" competition and she wants to write a recipe book for kids. "I want it to be fun to read and easy enough for children to use," she says. Gina learned by watching her father, who's also good at cooking, in the kitchen. She wants to encourage other children to cook because "everyone needs to eat so it's a skill that will always be useful!"
Seventeen-year-old Brian used to love running until he was hurt in a serious accident three years ago. He lost part of one leg and didn't even expect to walk again. Now he's an athlete who has recently taken part in a long race. "After my accident I wanted to give up," he says. "But now I'm happy to be alive and able to continue running."
Helen has always been good at science, but she thought it was too difficult to become an inventor. Then she heard about an accident that had happened when a car hit a train in her town. "That gave me an idea," says the clever sixteen-year-old. It took her over a year to invent a small special machine that tells car .drivers when a train is coming. One company is already interested in selling it, so it may be in he shops soon!
Do you know a child like them? Please e-mail us at amaxingkids@ mail. com and tell us why he or she should be on our radio. Thank you.What was Gina the winner of?
Does Gina want to write a children's recipe book? Why?
Why is it surprising that Brian is an athlete?

Do animals have a culture? What do we mean by "culture"? Recently social scientists have begun to ask if culture is found just in humans, or if some animals have a culture too. When we speak of culture, we mean a way of life that a group of people have in common. Culture is the forms of behavior (行为)hat help people to live together. It is also the forms of behavior that make one group of people different from another group.
Human beings use tools, cooperate with one another, and communicate with language. But these aspects(方面) of human behavior, or "culture", can also be found in the lives of certain animals, Animals can make tools, for example. We used to think that the ability to use tools was the dividing line between human beings and other animals. Lately, however, we have found that this is not the case. Chimpanzees(黑猩猩) can not only use tools but actually make tools themselves. Animals can also share knowledge with each other and use their own language to communicate. So it may be important for us to know that the line dividing us from animals is not as clear as we used to think.According to the article, "culture" means
A. the languages we learn
B. the good habits we' share with each other
C. the forms of behavior we have in commonFrom the fact that chimpanzees can use and make tools，we know

B. knowledge and communication are no longer signs of only human behavior
C. the line dividing human culture from animal culture is not as clear as we might think
