5 Austrian zoologist Karl von Frisch won the 1973 Nobel Prize in physiology( 生理学 ) or medicine. He discovered a number of pioneering breakthroughs ( 突破 )in animal behavior.

6 Step 1:fast reading Step 2:careful reading Step 3:consolidation Step 4: rewarding ceremony Four steps to go

7 Task for you: read the text quickly and do the true or false Step 1

8 All bees do not live in trees. Honey-bees interested scientists most. Bees communicate the news of food to other bees outside their hive. There are three dances mentioned in the text. The minimum distance bees flew was 3.2 kilometers. inside two or maximum

9 find out the right main idea for each paragraph Task 1 : Step2:Careful reading

10 Para. 1 Para. 2 Para. 3 Para. 4 Para. 5 Para. 6 Para. 7 Para. 8 1.The circle dance 2. A brief introduction of the bee 3. Whether bees could tell each other the exact position. 4. The wagging dance. 5. Pro. Karl von Frisch built special hives to study bees. 6. The number of wagging dances indicates the exact distance to the feeding place. 7.“Bee-line” and “ to make a beeline for ” 8. Something about the professor Match the general idea of each paragraph.

11 Para 1 A brief introduction of the bee Para 2 Pro. Karl von Frisch built special hives to study bees. Para 3 The circle dance Para 4 The wagging dance. Para 5 The number of wagging dances indicates the exact distance to the feeding place. Para 6 Whether bees could tell each other the exact position. Para 7 “Bee-line” and “ to make a beeline for ” Para 8 Something about the professor

12 Task2 careful reading to find out bees’ ways to communicate food information Para 4-5 wagging dance Para 6 more information Para 2-3 circle dance

13 Q2: what did he find in his first experiment? Q3: And what conclusion he drew? The circle dance communicated news of food. Para2-3 Q1.What was Professor von Frisch puzzled by? The bee began to perform a dance on the surface of the honeycomb.

14 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. Q1.What was Professor von Frisch puzzled by?

15 First it made a______ to the______, then to the left. It _______these circles over and over again. Then the surrounding bees ______behind the first dancer, ______ its movements. circle right repeated trooped copying

16 Q3: What did Karl Von Frisch want to know next? whether the dance can tell whether the feeding place is nearby or far away. Para 4-5

17 Q4: What other kind of dance did he find in his experiment? And what’s the difference between the two? A wagging dance.

18 The dancer ran in a _______line, wagging from side to side. Then it turned in a__________, ran _______ again, and turned in________ semicircle to the_________ side. It kept the “steps”_______________ straight semicircle another opposite over and over. straight

19 all the bee came to the nearby Feeding place doing All the bees came to the faraway place doing wagging dance circle dance

20 food is nearby food is faraway Dance Wagging dance Circling dance conclusion

21 Q5:What Karl and his partners find in para5? And how the bees told the distance ? They discovered that the farther away the feeding station was, the slower the dance was. The number of wagging dance per Minute could show the distance.

22 what do you think the remaining question is? The remaining question was to find out whether bees could tell each other the exact position of a feeding place. Para 6

23 Far away? In which direction? It it my favorite ?

24 Do the following exercises to see how much have you comprehend about the passage Step three: consolidation

25 A circle dance A wagging dance A faster wagging dance A slower wagging dance Food is near. Food is far away. Food is closer. Food is farther away.

26 1. Karl von Frisch made an experiment to research_____. A.the food of honeybees B.the dance of honeybees C.the ways honeybees communicate D.the hive of honeybees

27 B. feeding places 2. Different dances indicate different _____. A. food C. steps D. semicircles

28 3. After the marked bee danced, the other bees ____. danced together B. became very excited C. Seemed not to notice it D. both A and B

29 4. Which of the statement is possible according to the paragraph 7?____ A.We human beings can communicate as honeybees do. B.We human beings can go as quickly as honeybees. C.We human beings can come to help each other in a fast way. D.We human beings can learn something from animals’ behavior.

30 5. In the morning if a feeding place is set up 3 kilometers to the east of the hive, which picture correctly shows honey bee’s dance. A. B. C. D

31 step four: Karl Von Frisch got a noble Prize together with his partner. Now suppose we are at a rewarding ceremony, one of you is Karl Von Frisch, the others are reporters from different stations.

32 Use a book as a bee does flowers. 读书如蜜蜂采花,吸取其中之精华 No bees, no honey; no work, no money. 没有蜜蜂就没有蜜,没有劳动就没有钱. bee’s knees 最有价值的人 One’s head full of bees 想入非非, 异想天开

35 1.What did the scientist assume first? 2. What did they do for their assumption? Was it proved? 3.What kind of a dance was found? 4. What was the conclusion? 5. What was the other dance? 6.What information did it convey? 7.What’s the difference between the two? two dances 8.What do you think the remaining question is?
