     What time can you have breakfast? Breakfast is very important and you must eat it. People eat

breakfast in one or two hours after they get up. It's good to eat breakfast before nine o'clock.. Some

people don't eat anything in the morning. Some are very busy. Others want to be thin. But both (两个

都) reasons are bad. It's difficult to work or study well without breakfast, and it can't help one get thin.

In fact, if one doesn't eat breakfast, it may even make one fat. In the morning, you must eat some good

food. You can eat some eggs, some bread and drink some milk. You can eat some chicken as well. If

you get up late after nine o'clock, you still must eat breakfast. You can eat it in one or two hours after

you get up.
