All of them are food for animals and people. Grain can be fed to animals just as it is harvested. But before people use them grains are usually made into flour or breakfast cereal. Bread, macaroni（通心粉）, and cereals（麦片） all come from grain. Tomatoes, beans, potatoes, beets（甜菜）, lettuce（生菜）, carrots and onions are field and garden vegetables. Can you think of any others? Vegetables are good for people and for some animals such as pigs and rabbits. Farms that grow vegetables for city people to eat fresh are called truck farms. Truck farms are usually close to big cities. Each day hundreds of loads of fresh vegetables are brought to stores on the farmers trucks. Without the truck farmers people in cities would not eat well. And without city people who eat fresh vegetables, the truck farmers would have no work. There are many kinds of fruit. Apples, pears, peaches, cherries, oranges, grapefruit, and berries are a few kinds. You will be able to think of other kinds that you like. Most fruit is grown on specialized farms. But many general farms have some fruit to use and sell also. Like vegetables, fruit is sold fresh in markets. But a large part of both fruit and vegetable crops is sent to factories to be canned or frozen. In warm parts of our country farmers grow cotton, rice, tobacco, sugar cane（甘蔗）, and peanuts. Specialized farms raise flowers and garden plants. They are sold to florists（花商） and to families for home gardens, or yards, or window boxes. A farm that grow plants and flowers to sell is called a nursery（苗圃）.
