5. Pre-reading 1. How do animals communicate? Animals communicate by Strange noise Body language 2. What kind information do they communicate? Animals communicate about If they are angry or friendly How they feel Where there is food or danger 3.If I were a zoologist, what would you study about animals communication? Their languages behaviors Animal living styles

6. Skimming 1. How do honey-bees communicate with each other? 2.What are they telling each other? Please skim the passage to answer the questions below. Keys: 1.They do different dances, a circle dance and a wagging dance. 2.They are able to tell each other that food has been found and how far away the feeding place is.

7. Scanning Please scan the passage to tell me how many parts it is divided into and what the main idea of each part.

8. Skimming Part1(Para1) The honey-bee has interested scientists most because of their communicating “language”. Part2(Paras2-7) Karl Von Frisch’s experiments on honey- bees. Part3(para8) Karl Von Frisch’s won the Noble Prize for his work in studying the communication of animals.

9. Details Please read the passage carefully and answer the questions below. 1. Where do you find bees? In the wild, in gardens, fields or orchard.

10. Details 2.Where do bees live? In a hive.

11. Details 3. What do bees make? honey

12. Details 4. When Professor von Frisch places little dishes of honey on a table, what was he puzzled by? As soon as one bee discovered the honey, many more came to it one after another in a short time.

13. Details 5. What did Karl Von Frisch, a scientist from Austria, spend many years researching? He spent such much time researching the amazing ways honey-bees communicate in their dark hives.

14. Details 6. In order to solve the puzzle, how did he do? Von Frisch built special hives, each with only one honeycomb. He built a transparent wall through which he could observe what went on inside.

15. Details 7.In order to tell the bees apart, what did he do? He painted some bees with little dots of color.

16. Details 8. What did he observe through the transparent wall? He observed a marked bee returned to the hive from the feeding table, performed a dance on the surface of the honeycomb and surrounding bees copied his movements. Then the bees left the hive and went to the feeding place.

17. Details 9.What did the circle dance seem to communicate ? The circle dance seemed to communicate news of food.

18. Details 10.Von Frisch assume that the dance conveyed more information. To clarify the assumption, what did he do? He set up two feeding places. One was close to the hive, the other much far away. He marked all the bees that came to the nearby feeding place blue, and all the bees that went to the far-away place red.

19. Details 1I.When the bees came back to the hive, what did von Frisch see ? All the bees that that had been at the nearby feeding places were doing circle dance While the bees that had been at the distance feeding place were doing wagging dance.

20. Details 12. We know honey- bees communicate by a circle dance and a wagging dance. Can you describe how the circle dance performed ? What about the Wagging dance? Can you tell me which picture is the circle dance? Which is the wagging dance?

21. The circle dance First it made a circle to the right, then to the left. It repeated these circles over and over again.

22. 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.

23. 13.How did bees tell the exact distance of the feeding place? The number of wagging dances per minute told the exact distance of the feeding place.

24. 14. Could bees tell each other the exact position of a feeding place? After doing more experiments to obtain data, The zoologists clarified the procedure by which bees communicate information that they use to find and fetch food.

25. A circle dance A wagging dance A faster wagging dance A slower wagging dance Food is closer. Food is farther away. Food is near. Food is far away. Quiz Please match each dance on the left column with the proper feeding place on the right column.

26. Retelling Please listen to the tape and fill in the blanks according to the text. The honey-bee has interested scientists most because of their communicating “language”. A scientist from, Professor Karl von Frisch,spent many years studying how honey- bees. Von Frisch set up two places, one is to the hive, the other was much far away. He that the bees that had been a Austria communicated feeding close observed

27. Retelling at the nearby feeding place were doing the dance while the ones that had been at the faraway feeding place were doing dance. In addition, he both of the two dances : the circle dance told the bees about the of the feeding place while the wagging dance about the of the feeding place was. The of wagging dances per minute told the circling wagging took apart location distance number exact

28. Retelling distance to the feeding place. After designing experiments, Karl von Frisch with his partners the procedures by which bees communicate information that they use to find and food. Because of his devoting all his life to studying the communication of, he was awarded a in 1973. clarified fetch animals Noble Prize

29. Homework 1. Retell the text. 2. Do Ex.3 of post-reading to find out more information about the language of bees.
