C 根据下面短文回答下列问题。 Long ago people used bells more than they do today. The postman would ring a hand bell (摇响手玲) when he sent the letters. People who sold things came past houses, ringing a bell and shouting (叫喊) what they sold. The countryside had its church (教堂) bell to let people know it was time to go to church. At night, this bell rang so that travelers would find the place in the dark. In most countries, bells were put around the necks of animals. The bells helped owners to find their lost cows or goats (牛羊). Now bells are not used as often as before. But people still try to keep the old bells in schools and churches so they will not lose their beautiful sounds. In the past, people used bells when they sent letters or sold things.
