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 ,and many other students choose rolling 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 . 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! If a child carries a heavy school bag, _ . A) his back and neck may be hurt. B) his head and arms may be hurt . C) his hands may be hurt . D) his feet may be hurt .

If you ask me to tell how to get along in the United States, I think the following "do's" and "don'ts" would be helpful. Generally speaking, it isn't easy to find anyone to talk to in a busy city, so you should try to do the following. First, get or borrow a dog! Walk him several times a day! Americans love dogs and cats and usually stop to talk to anyone with a dog. Then, try to eat in a restaurant. People generally share the same table and will sometimes talk to you if they see you are new there. Next, take your dirty clothes to a laundry ! It takes about an hour to wash and dry them and people there often pass the time talking with each other. Always ask for information from a woman if you are a man, and from a man, if you are a woman! Learn to say, "Please" "Thank you" and "You're welcome" and use them all the time! There are some things you shouldn't do. Don't tell the truth when people ask, "How are you?" The only answer they want is "Fine". Never ask people their age--especially women! Everyone wants to be young. Don't tell heavy people they are fat. Tell them they are losing weight. Everyone wants to be thin. Don't be late when meeting people! When someone says six o'clock, be sure to be there by six. Americans respect time and want everyone to be "on time". If you visit a friend, you _ . A) can be there at any time B) may be there a little late C) had better arrive every early D) should be there at the right time
