A recent study shows that nearly 50 percent of the school "kids in Beijing do not have breakfast。 They tend to feel sleepy all day and have bad memories， so it is hard for them to get high marks in all kinds of test。

Some students who study late into the night choose to miss breakfast so that they can have a few extra minutes in bed。 Others are given money to buy their breakfast on the way to school because their parents are too busy to prepare it for them。 In addition， a few schoolgirls want to stay slim and often go to school without breakfast。
