当一个地方被比喻为 a hive of activity 时，要表达的意思是此处看上去非常忙碌，一片繁忙的景象。
- La Bouqueria market is a hive of activity on a Saturday morning, with vendors selling all sorts of food and drink.
- Welcome to the department! It's a real hive of activity, but don’t worry, you'll soon get the hang of it.
- London was a hive of activity over the summer, with lots of tourists and spectators who came to see the Olympic games.
值得注意的是，如果一个地方人特别多，场面热热闹闹，这时可以用 buzzing 来形容此地。
- The nightclub was packed with people last night; it was really buzzing.
