听力原文：  Bees are very small animals which fly through the air to look for flowers for food. When a bee has found some food, it returns to their home called a hive and dances. The dance is the way the bee communicates to other bees the fact that it has found food.

  Bees do two kinds of dances to tell other bees of their discovery of food. First, there is a round dance. The bee moves in a circle inside the hive. The round dance is used when food is close by, not more than ten meters away. The other bees also smell the bee that has found the food. The smell tells them what kind of flower to look for. After watching the round dance and smelling the bee that has found the food, the other bees can find the food source.

  A second kind of dance done by the bees is a tail-wagging dance. The tail-wagging dance is used when the food is more than ten meters away. The bees know from the speed of the tail-wagging dance just how far away the food source is. The line the bee dances on shows the direction that the bees must fly in to find the food. The bees also smell the bee that has found the food to know what kind of flower to look for.

What do the bee's round dance and tail-wagging dance indicate?
