    Bees in a colony work with each other to gather food, and they try to find the most nectar (花蜜)in the least amount of time possible. A small number of bees work as searchers, but when a good flower patch (花丛) is found, how do they tell other bees where to find it?

    Bees communicate flower location using special dances inside the hive, where bees live. One bee dances while the other bees watch. The dancing bee smells like the flower patch, and also gives the watching bees a taste of the nectar she has gathered. Smell and taste helps other bees find the correct flower patch. Bees use two different kinds of dances to communicate information: the waggle (摇摆) dance and the circle dance.

    Waggle dance

    The waggle dance tells the watching bees two things about a flower patch's location: the distance and the direction away from the hive.

A. Distance

    The dancing bee waggles back and forth as she moves forward in a straight line, then circlesaround to repeat the dance. The length of the middle line, called the waggle run, shows roughly how far it is to the flower patch.

B. Direction

    Bees know which way is up and which way is down inside their hive, and they use this to show direction. How? Bees dance with the waggle run at a specific angle away from straight up. Outside the hive, bees look at the position of the sun, and fly at the same angle away from the sun.

    Circle dance

    The circle dance tells the watching bees only one thing about the flower patch's location: that it is somewhere close to the hive.

    In this dance, the bee walks in a circle, turns around, then walks the same circle in the opposite direction. Sometimes, the bee includes a little waggle as she's turning around. The duration of this waggle is thought to indicate the quality of the flower patch.

1. （1） Why does the searcher give the watching bees a taste of the nectar?

   A . To inform them of the distance of the flower. B . To celebrate her success of finding the nectar. C . To motivate them to collect the nectar. D . To ensure the bees find the right patch.
3. （2） Which of the following statements is TRUE about the dances?

   A . The searcher's waggle means little during the circle dance. B . The waggle dance indicates the direction of the flower patch. C . The waggle dance shows precisely how far the flower patch is. D . The quality of the flower patch is not shown in the circle dance.
5. （3） If the searcher dances inside the hive in this way(see the right picture), which of the following is the WRONG flying direction for the other bees?

   

   A . B . C . D .
