Section D
听力原文： Bells have been in existence for a long time. They were used by the Chinese about 6,000 years ago and the oldest bell ever found is around 7,000 years old. Today, we live in a world of mass communications and reliable clocks, so it is easy to forget what an essential part of everyday life bells used to be.
Bells told people of happy events, such as wedding and births, or sometimes had to announce unpleasant events such as a death or a funeral. Sometimes bells were used for giving people warnings of an enemy's approach or spreading the good news of victory.
In many places today, bells are perhaps most commonly associated with announcing when religious services are going to take place. They are also frequently rung during celebrations and continue to play a part in many people's lives.
