     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 of the restaurant will look at him or her angrily. If some people

are talking too loudly, the manager (经理) of the restaurant may come out and ask them to be quiet.
