     The food my British friends eat in Britain is very different from our Chinese food. For example, they

eat a lot of potatoes. They like to eat them every day. They eat bread for breakfast and usually for one

other meal. They eat their bread with butter, cheese, or jam, things we don't eat much in China. Cheese

and butter are made from milk. They drink a lot of milk, too. They drink the milk cold or hot, and they

put it in their tea. They put sugar in their tea as well. They are the world's biggest tea drinkers. They like

Chinese tea, but they drink mostly strong black tea from India and Sri Lanka (斯里兰卡). They don't eat

much rice. For their main meal they like meat or fish with potatoes and one of two vegetables. They serve

(供应) all these together. Later they always have something sweet. They call this dessert. They don't have

Jiaozi in Britain.
