Step 1 Fast reading Answer the following questions 1. How do honey bees communicate with each other? (Para 3) 2. What information do the two dances convey? (Para 4) 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”.

Primates. Primates include other mammals such as apes and monkeys, and they share certain characteristics. Step 2 Fast reading 1 What are the key features found in primates? (Para 1) 2 Do you think it is possible to teach chimpanzees to use language and do other things that we consider typically human? Why or why not? (Para 6) 3.Can you name some key features found in primates? Their hands and feet can grasp and often have opposable thumbs and toes. 4. Which two groups are the primates divided? Higher primates and lower primates. Or new world primates and old world primates. 5. What are the differences between apes and monkeys? Apes have no tails, nearly all monkeys do; apes tend to be larger and walk more upright; apes use sight more than smell. Apes also have more developed brains and give birth to fewer young. They use facial expressions, body language and sounds to express themselves and they can even use colour and smell to communicate. 7. Why the experiments may not tell us much about how chimpanzees think and what they are able to do? The reason is what the chimpanzees are trained to do is not natural to them, nor does it make much sense to the animals. Step 3 Careful reading Scan the passage and complete the chart below: Types Characteristics and examples Primate 1. hands and feet can grasp and often have opposable thumbs and toes; 2. have a better sense of touch and the primate brain is larger. 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 Suggested answers to Ex 1 on Page 126 Primates Primates have hands and feet that can grasp or thumbs and toes that are opposable. Primates also have a highly developed sense of touch and a brain that is larger—compared to body size—than that of other animals. Other animals Other animals have smaller brains compared to their body size. Higher primates Larger brains Lower primates Smaller brains Monkeys Most monkeys have tails; monkeys are smaller and doesn’t walk upright as apes; their brains are less developed. Apes Apes have no tails; apes tend to be larger and walk more upright; apes use sight more than smell; an ape’s brain is more developed; apes have fewer young New world primates The group includes, among others, the spider monkey and the night monkey. New world primates are usually small and live in trees Old world primates The group includes monkeys, apes and humans. Old world primates are bigger and spend more time on the ground. Suggested answers to Ex 2 on Page 126 Higher primates, such as chimpanzees, are genetically very similar to human beings. They walk like us (upright) and have hands and feet that can grasp. Chimpanzees and other higher primates also behave in “human” ways: they live in groups, they communicate with each other, and they use tools to find and eat food. However, these similarities do not mean that higher primates necessarily think like humans or are able to do what humans do, such as the solve problems and use human language. Some primates, such as chimpanzees, also still have opposable toes, but human beings don’t. Step 4 Discussion Do you think it is possible to teach chimpanzees to use language and do other things that we consider typically human? Why or why not? Step 5 Language points 1.That means that primates are better than other animals at holding, moving and using objects. better than other animals是比较级表最高级的用法.
