Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day. They are: green and yellow vegetables of all kinds；citrus(柑橘) fruit and tomatoes；potatoes and other fruit and vegetables；meat of all kinds, fish and eggs；food made from milk；bread or cereal(谷类), rice is also in this kind of food；butter or something like butter.

People in different countries and different places of the world eat different kinds of things. Food is cooked and eaten in many different kinds of ways. People in different countries eat at different times of a day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether food is eaten raw (生的）or cooked, canned (罐装的）or frozen. It doesn’t matter if a person eats dinner at four o’clock in the afternoon or at eleven o'clock at night. The important thing is what you eat every day.

There are thousands of rivers all over the world. Many of them are famous, such as the Mississippi in the United States, the Nile in Egypt, the Ganges in India, the Amazon in Brail, the Yangtze River in China and so on. Rivers are one of the most important natural resources. They are very useful and helpful.

Firstly, they can be used for transportation. Many of the world’s great cities are located (坐落) on rivers，and almost every country has at least one river flowing though it. So people can use ships to carry goods, materials or other things from one city to another easily. People can take a trip to other places by ship easily, too.

Besides transportation, rivers also give food, water to drink, water for crops, and chances for fun and entertainment for the people who live along their banks. In order to increase the supply of water for crops, engineers sometimes build a dam(打坝)across a river and let a lake from behind the dam. Then people can use the water not only lo irrigate their fields but also to make electricity for their homes and industries.

However, large cities and industries that are located upon rivers often have problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted. It can't be used to irrigate the fields, not even for drinking. Luckily, people realize the problems. They are trying their best to stop the rivers from being polluted.

河流是最里要的自然资源之一，它对人类有着重要意义，除了生活和工业、农业用水外，还具有航运、繁殖、旅游等作用。然而，世界上的河流正在遭到人类的破坏，请你写一篇短文，谈谈你的看法。

Rivers are very important to us.
