( ) 4. The experiment described in Para.5 was designed with the purpose of finding out________. A. how many times the bees repeated the dance during one minute. B. how often the bees dance C. if the wagging dance told the other bees exactly how far away the feeding place. D. if the other bees could get to the feeding place.

1.The “language” used by the honey-bees to communicate with each other arouse scientists’ interest in them.. 2.Professor Karl von Frisch built special hives as well as a transparent wall for the purpose of observing bees. 3.After seeing one bee’s dance, the surrounding bees leave the hive and go to the feeding place directly. 4.The bees from close feeding place perform a wagging dance.
5. Of the two dances, the circle dance and the wagging dance, the latter one indicates a close distance while the former one indicates a farther distance. 6. The expression “to make a beeline for someone or something” means to go quickly along a straight course for someone or something. 7. In 1973 Professor von Frisch was awarded a Noble Prize as a result of making a great contribution to animal research..

Careful Reading Para.1 a brief introduction of the bee Q : Why is it the honey-bee that has interested scientists most? Because of the language they use to communicate with each other.
Para.2 Pro. Karl von Frisch built special hives to study bees. What was Professor von Frisch puzzled by? When he placed little dishes of honey on a table, bees soon came. As soon as one bee discovered the honey, many more came to it one after another in a short time.
Para.3-4 the circle dance and the wagging dance Can you describe how the circle dance performed? And how the wagging dance performed? First it made a circle to the right, then to the left. It repeated these circles over and over again. Then the surrounding bees trooped behind the first dancer, copying its movements.
Para.3-4 the circle dance and the wagging dance The dancer ran in a straight line, wagging from side to side. Then it turned in a semicircle, ran straight again, and turned in another semicircle to the opposite side. It kept the “steps” over and over.
Para.5 The number of wagging dances indicates the exact distance to the feeding place. 1. What did the scientists discover? 2. What a maximum distance do the bees fly? Bees fly a maximum distance of 3.2 kilometres between their hive and a feeding place. They discovered that the farther away the feeding station was, the slower the dance was.
What was the remaining question for Professor von Frisch and his partners? Para.6 The remaining question was to find out whether bees could tell each other the exact position of a feeding place.
To make a beeline for someone or something means: Para.7. To go quickly along a straight course for somebody or something.
Para.8 Karl von Frisch Frisch is best known for his studies of bees. He found that bees communicate the distance and direction of a food supply to other members by two types of rhythmic movements or dances:circling and wagging. The circling dance indicates that food is within 75m of the hive, while the wagging dance indicates a greater distance.
根据课文内容填空 : There are many _________ of bee. Among the different types of bee, it is the honey-bee that has most interested scientists because of the “language” they use to _______________ with each other. The scientists Von Frisch built special hives to find out how one bee communicate the news of food to the other bees in the hive. varieties communicate
To his _____________, the bee who found the feeding place began to _________ a dance on the ________ of the honeycomb. The dance seemed to _______ the surrounding bees. They _________ behind the first dancer, _________ its movements. Then the bees left the hive and went to the _______ place. He found that the bees did the circling dance when the food is near, and that the bees did the ___________ dance when the food was far away. astonishment perform surface excite trooped copying feeding wagging
