Enable the students to discuss the questions on p120. Step 2. Scanning Task 2. Get the students to comprehend the passage quickly and accurately, and meanwhile help them to form a good habit of reading. Try to find out the main clue of the story. Step 3. While-reading: True or False: ( ) 1. Von Frisch and his co-workers counted hoe many times the bees repeated the wagging dance during one hour. ( ) 2. They discovered that the farther away the feeding station was, the faster the dance was. ( ) 3. The number of wagging dances per minute told the direction to the feeding place. ( ) 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 place was toward the sun, the dance headed straight onward during the straight part of the wagging dance. ( ) 7. The experiment of Professor Karl Von Frisch tells us that bees can and do communicate with each other by their dances, which may be called a kind of “language”. Suggested Answers: FFFTFFT Step 4. Post-reading Finish all the Ex. On p122 Step 5. Further Reading Task 3: Read the passage once again and try to divide the text into some big parts. And make a summary of each part: Part 1: (Para 1) Some basic knowledge about bees. Part 2: (Paras 2-8) Professor Von Frisch’s experiment. Part 3: (the last Para) The late life of Professor Von Frisch. Step 6. Homework Finish all the exercises on Language Practice on p123-124. Period 2. Integrating Reading Skills Primates (P124-125) Step 1. Revision 2. Check the homework. Review the Model Verbs Step 2.

Other animals 1. not good at holding, moving, and using objects; 2. have a weak sense of touch and small brain. Higher primates Large size of brain, such as human beings and apes. Lower primates Small size of brain. Monkeys Have tails, small and walk less upright. Apes not tail, larger and walk more upright, use sight more than smell, developed brain. Now world primates Bigger and spend more time on the ground, such as monkeys, apes and humans Step 3. Careful reading: Ask the students to read the passage carefully and answer questions 2 on Page 126. Period 3. Integrating Reading and Writing Skills 2 Passages on p 252-254 Step 1.

Guided Writing Give Ss 20 minutes to finish the writing assignment on p117, Then ask Ss to score their work according to the following chart. 3 pluses & 1 wish Name _______ Title _____________________ Date _______________ + _________________________________________________________ + _________________________________________________________ + _________________________________________________________ ? _________________________________________________________ Note: How to use this chart effectively? Ask the student to read his/her deskmate’s writing carefully, and then find 3 valuable things (structure, passage arrangement, sentence, diction, etc) and give 1 suggestion. And then feed the message back. Next, ask the Ss to correct their work according to the chart. Period 4: Step 1. Analyze some long sentences: Deal with some language points and difficult points if necessary. If possible, guide the students to analyze some long and complex sentences. The following sentences in this unit are very important: Among the different kinds of bees, it is the honey-bee that has interested scientists most because of the “language” they use to communicate with each other. In order to tell the bees apart, he painted some bees with little dots of colour. For his lifetime’s work in studying the communication of animals, including honey-bees, Professor Karl von Frisch was awarded a Nobel Prize in 1973, which he shared with two other scientists. They trooped behind the first dancer, copying its movement. After designing more experiments, they were able to clarify the procedure by which bees communicate information that they use to find and fetch food. Like all other living creatures, human beings belong to a group of other animals that share certain characteristics. Step 2: Testing your skills on P250-251 Step 3: Cloze Test on p255-256 Step 4: Translating on P 256 转自北京英才苑网站 |
