They discovered that the farther away the feeding station was, the faster the dance was.l ( ) 3. The number of wagging dances per minute told the di
2、rection to the feeding place.l ( ) 4. Then Professor Von Frisch did his third experiment, which was to discover whether the wagging dance showed direction.( ) 5. He found that the straight part of the dance was the same in the morning from what it had been in the afternoon.( ) 6. If the feeding plac
3、e was toward the sun, the dance headed straight onward during the straight part of the wagging dance.( ) 7.

11、dingl Para.1 a brief introduction of the beeQ: Why is it the honey-bee that has interested scientists most?Because of the language they use to communicate with each other.l Para.2 Pro. Karl von Frisch built special hives to study bees.What was Professor von Frisch puzzled by?When he placed little di
12、shes 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.l Para.3-4 the circle dance and the wagging danceCan you describe how the circle dance performed?

Then it turned in a semicircle, ran str
14、aight again, and turned in another semicircle to the opposite side. It kept the “steps” over and over.l Para.5 The number of wagging dances indicates the exact distance to the feeding place.1. What did the scientists discover?They discovered that the farther away the feeding station was, the slower
15、the dance was.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.l Para.6What was the remaining question for Professor von Frisch and his partners?The remaining question was to find out whether bees could tell each other the exact positio
