In the world， only a few people can live up to（活到） one hundred years. Why can they live up to one hundred？ Because they have a healthy diet. How can we have a healthy diet？ First， we must eat a lot of cereals（谷类）. Then， we must eat lots of vegetables and fruits. We also need to eat eggs and a little meat every day. At last， we need a little milk and oil every day. Of course， we must drink much water every day. If you could do these well， maybe you can live up to one hundred.
