It seemed to take an immediate liking to the man, because it walked up to him and then followed him wherever he went.This was funny for a while but in the end became rather embarrassing . "Go away, you silly bird, ''the man said to the penguin, but the bird ignored him. It simply would not leave him alone.Wherever he went, the bird went too. At last, in desperation the man walked into a police station."Excuse me, officer." he said. "I need some advice. I met this penguin in the street and I don't know what to do with it." A bored policeman looked up from what he was writing and said, "Just take it to the zoo, sir.'' "Oh,all right.''said the man. The next day the man was walking along the street, still accompanied by the penguin, when he met the policeman he'd spoken to the day before.The policeman was not pleased to see them."I thought I advised you to take that animal to the zoo, " he said. "Well, yes, officer, you did.And I did take him to the zoo, " the man explained. "And we had a great time. But we can't go to the zoo every day.I thought today I'd take him to the movies.''

[EX Q]: Article: In October on the east coast of Australia migrating humpback whales pass very close to the shore. With the help of Max Egan, we went to film them near Byron Bay. It was extremely exciting to spot the little puffs of spray on the horizon. When migrating, the whales can be traveling at speeds of about 12km/h and can dive under anywhere between five and forty minutes, but with many years of experience Max usually guided our boat to exactly the right place to provide us with amazing sighting. As the whales break the surface like submarines , the water spills off their broad dark backs and huge tails. Then, with a powerful down stroke, they dive back into the depths of the sea, leaving just a smooth glassy patch of water or "footprint" on the surface to show where they had been. One day we had traveled up and down the shore and far out to the sea in search of whales, but the horizon was deserted. There was no report of whales in the area so we decided to test out Max's new, highly sensitive hydrophone and the result was astonishing. As soon as the hydrophone was in the water, we found ourselves listening to the most beautiful voices. What may have seemed like a vast empty ocean was filled with the singing of whales. It is the males which sing, as they migrate between feeding and breeding grounds. No one knows for sure what the purpose of these songs is, whether they are love songs to the females or warnings to other males to stay away. It was thought that each population of humpbacks had its own song which remained regular but recent findings suggest that the whales appreciate a memorable tune and quickly adopt any new songs they hear.
Answer: The songs of whales.
[EX A]: Which finding about whales is beyond the writer's expectation?
