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 “l(fā)anguage”.

Integrating Skills

Step 1 Lead in

Which group do the zoologists place human Beings? 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.

6. What do primates use to express themselves and communicate?

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
