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 that younger and younger students are having back and neck problems as a result of school bags being too heavy for them.

“It’s hard for me to go upstairs with my bag because it’s so heavy,” said Rick Hammond, an 11-year-old student in the US.

Rick is among students who have common school bags with two straps(帶子) to carry them, but many other students choose rolling(有滾輪的) bags.

But even with rolling bags, getting up stairs and buses is still a problem for children. Many of them have hurt their backs and necks because of the heavy school bags.

But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight(重量).

Scott Batch, a back doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don’t stay with over 15%, because their bodies are still growing.

“Children are losing their balance(平衡) and falling down with their school bags,” he said.

Parents and teachers are starting to tell children to only take home library books they will be reading that night. Some teachers are using pieces of paper or thin workbooks for students to take home.

One of the best answers is, as some children said, to have no homework at all!

What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist(樂觀者), a leader, an active person who enjoys life, people and excitement. Do you prefer grays(灰色)and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined(意志堅(jiān)定的). You wish to succeed and want other people to see you are successful. At least this is what psychologists(心理學(xué)家)tell us, and they should know, because they have been seriously studying the meaning of color preference(愛好), and the effect(影響)that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

　 A yellow room makes us feel more cheerful(開心的)and more comfortable(舒服的)than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing(壓抑). Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.
　　 Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.
