Once upon a time，a cat，a flag and a camel were good friends．They decided to tell each other the story of their birth to find out who was the oldest．

The cat told his story first．“When I was born, he earth was still soft．I had to walk very carefully so that I did not sink into the ground．That’s why I’m still very careful about the way I walk．”

“Oh! That’s nothing．”exclaimed（惊叫）the frog．“I’m sure I’m the oldest．When I was born, the earth was very hot．It was too hot to walk on．The only way to move around was to jump．That’s why I still jump rather than walk．”

The camel was very amused（开心）．“When I was born，”he told his friends，“the earth had not yet been made．There was only the sky and a lot of sand everywhere．When my father died，there was no place to bury him so I had to carry him on back．That’s why my back is crooked（弯曲的）．Of course，it’s very useful as I can keep food and water in it．”

After hearing what the camel said，the cat and the frog had to agree that he was the oldest．They made him their leader．What do you think of the story?

1．How many animals were there in the story?

2．Why did the frog jump according to the passage?

3．Why was the camel’s back crooked according to the passage?

4．Who became the leader at last?

5．Do you agree what they said?
