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!

When we see a cigarette box, we’ll see “ Smoking is harmful to your health” on it. Children are not    36  to smoke by their parents or teachers. But in many countries  37 is becoming a bigger problem for young people. Most smokers   38  in their teens or earlier.

Some students think smoking is very cool, and they can see many people smoking around them. They want to have a   39 .

“If young people start smoking early, they will probably get addicted （上瘾的）to nicotine（尼古丁）. And it will be very hard to  40   later on,” said a professor. A study shows smoking is a problem for many Chinese teens.  41    can we do to make them stop smoking?

Some people think we can make a law. Teenagers under 18 are not allowed to smoke,   42   they should be fined. Parents should give up smoking. They can set an example （树立榜样）43   their children.

“Every year about four million people die of smoking. And if people  44   smoking, the number will increase （增加）10 million a year from now on,” said the World Health Organization. So we must learn and tell others about the  45  of smoking.

Bob was happy. He was at a new school, and the other students were friendly. “Hi, Bob!” They said. But some students said, “Hi, Peter!” Bob didn’t understand. He asked another student, “ Why do some students call me Peter?”
“Oh, that is easy to answer,” the student said. “Peter was a student here last year. Now, he goes to a different school. You like Peter. Some students think that you are Peter.”
Bob wanted to meet Peter. He got Peter’s address(地址) from a student and went to Peter’s house. Peter opened the door. Bob couldn’t believe his   eyes. He looked really like Peter! Bob and Peter had the same color eyes and the same smile. They had the same black hair. They also had the same birthday.
