ToEFL - Listening - Lecture - Bees

Which aspect of bee behavior does the professor mainly discuss?

• Reproduction

• HIbernation

• Organization

• Communication

Why does the professor mention radar?

• To explain how bees know which way to fly

• To show how a theory was proved correct

• To illustrate problems with the waggle dance

• To confirm the accuracy of the round dance

According to the professor, what does the waggle dance tell forager bees?

• The distance of the food site from the hive

• The exact location of the food at the site

• How much food they will find at the site

• The weather conditions at the food site

Which way should forager bees fly if a scout bee flies up the side of the beehive in a vertical line?

• toward the west

• between sun and moon

• toward the sun

• away from the sun

Listen again to part of the passage and answer the following question.

Prof: Just a few years ago, though, the British scientists solved this problem using a new type of radar. They were able to attach a, uh, small radio transmitter to forager bees -- I don't know how, but they did.

What does the professor imply when he says this:

I don't know how, but they did.

• The scientists should have been more careful.

• It is difficult to put transmitters on bees.

• It is not a good idea to use radar with bees.

• He does not know how transmitters work.

What can be inferred about how forager bees find food?

• They rely solely on the information from the waggle dance.

• They rely completely upon their senses of sight and smell.

• They use the waggle dance to reach the area of the food.

• They use their senses to find the exact location of food.
