Are you carrying too much on your back at school? I’m sure lots of children of your age will say “Yes”. Not only the students in China have this problem, but children in the United States also have heavy school bags.

Doctors are starting to worry about young students’ back and neck because their school bags are too heavy for them.

“It’s hard for me to go upstairs with my heavy bag,” said Rick Hammond, an ll-year-old student in the USA.

Rick is among students who have school bags with two straps(带子),and many other students choose rolling(有滚轮的) bags.

But even with rolling bags ,getting upstairs is still a problem for children .Doctors say students should carry no more than 10% to 15% of their own body weight (重量)。

Scott Bautch, a back doctor, said children under Grade 4 should carry no more than 10% of their weight and older children shouldn’t stay with over 15% , because their bodies are still growing.

Teachers and parents should do some things to help children. And the best answer is to have less homework!

Molly Jackson was a happy little girl. She lived with her parents. Her parents loved her very much. Every morning, Mrs. Jackson would get up early to make breakfast. She also made lunch for Mr. Jackson. Then it was Molly's job to put her father's lunch box into a lunch bag. And she would give the lunch bag to her father.
One day, Molly gave two lunch bags to her father. "Why do you give me two bags, Molly?" asked Mr. Jackson.
"There is something else in the other bag," Molly answered.
"What's in it?" Mr. Jackson kept asking. "I can't tell you now. Just open it after your lunch," said Molly.
Time passed quickly, it was lunch time. Mr. Jackson opened his lunch bag and started to eat. Then he saw the other bag from Molly. So he opened this special bag.
In this bag, Mr. Jackson found some toys. There were some small model cars and pictures in the bag. And Mr. Jackson found a note(便条) at the bottom(底部) of the bag. It wrote, "Dad, here are some of my toys. You can play them in your free time and have a rest. I love you, dad."
