Eating habits (习惯) are different in different countries. The Chinese have a saying “Eat good things for breakfast, eat a big meal for lunch, but eat less at dinner.” Many Americans agree that one should start the day with a good breakfast, but their ideas about lunch and dinner are different.

?? Most Americans only give themselves a short time for lunch. So they eat a small lunch. After work they will have more time to eat a big dinner. Also a quiet dinner at home with all the family talking about their day is a way to take a good rest after a long, hard day of work.

?? Eating at restaurants is also different. In China, people like to talk and laugh while eating. Very often you can hear people talking and laughing loudly, and they are just having a good time. In America it is not like this. They want a quiet place where they can eat a good meal far away from the noises of the outside world. If someone is talking too loudly, the manager (经理) of the restaurant will look at him or her angrily. If some people are talking too loudly, the manager of the restaurant may come out and ask them to be quiet.

Most American children begin to go to school when they are five years old. American schools begin in September. There are two terms in a school year. The first term is from September to January, and the second is from February to June. Then the students have a great summer vacation.
High school students have only four or five subjects each term. They usually have same lessons every day, and teachers don’t ask them to do much homework. After school, they can do many interesting things like playing sports. Most students are seventeen years old when they finish high school.
After high school, many students go to college（大学）. They can go to a small one or big one. They need a lot of money to go to college. So many college students work after school to make money.
【小题1】American students always go to school in ________after summer vacation.

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!
