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!

Joan worked in a hospital as a nurse. One evening there was a big dance at the hospital. Most of the doctors and nurses would be there, but of course somebody had to be left to look after the sick children, and Joan was not of the lucky ones. She liked dancing very much, so when she had to start work that evening while her friends were getting ready to go to the dance, she felt very sorry for herself.
She went to each sick child one after another and said good-night, until she came to one little boy, Nick. He was eleven years old, but he was already able to talk like an adult. Poor Nick was badly ill, and now he was not able to move any part of his body except his hands. Joan knew he would never get any better, but he was always happy and always thinking about other people instead of about himself.
Nick knew that Joan loved dancing, so now when she came to say good-night to him, he greeted her with the words, “I’m very sorry that you have to miss the dance because of us. But we are going to have a party for you. If you look in my drawer, you’ll find a piece of cake. I saved it from my supper today, so it’s quite fresh. And there is also a dollar there, you can buy something to drink with that. And I’d get up and dance with you myself if I was able to.”

In most situations, light helps us see. But nowadays humans are using so much that it is in fact a kind of pollution.

When it comes to looking at the night sky, too much light makes it d  1.  for us to watch some of life’s most wonderful views: stars, p  2.  and even galaxies(星系).

According to scientific research, about 2, 500 stars can be seen by the human eye without u  3.  any special equipment(设备). But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city. In most big c  4., people cannot see the sky filled with stars like they did in their childhood.

Light pollution affects more than just our view of sky. Research s  5.  that lots of nighttime light can harm wildlife, too.

When birds fly to a  6.  place over cities, they sometimes get lost by the brightness and fly in circles(圈) u  7. they drop from tiredness. Sea turtles need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights.

Too much light at night m  8.  even affect human health, but scientists are not sure of that. They are still learning more.

In order to prevent things from going w  9., governments and some organizations are working to reduce light pollution. Many cities and towns have taken action to reduce the use of lights at night. Lights are used only when and where they are r  10.  needed.

Hopefully, in the near future, humans can enjoy the clear and beautiful sky again and all the wildlife will live a peaceful and undisturbed life, too.
