At the age of 16, Einstein always played with a group of naughty（调皮的）kids. Because he was so busy playing, he didn’t study enough and failed his final exam.

One morning, when Einstein was holding a fishing rod and was about to go fishing with his friends, his father stopped him and said calmly, “Einstein, you’re so fond of playing all day that you failed your exam. I’m worried about your future.”

“What are you worrying about? Jack and Robert also failed, but don’t they still get to go fishing?”

“My boy, you can’t think like that,”   his dad said. “There is a story that people tell in our hometown. Listen to it now.”

“There were two cats playing on a roof. One cat got caught off guard and fell down the chimney（烟囱）while holding the other cat. When the two cats climbed out of the chimney, one of the cats had soot on his face, while the other cat’s face was clean. Seeing the soot-faced cat, the clean cat thought its face must be dirty, so it quickly ran to the riverside and washed its face. The soot-faced cat saw the clean-faced cat and thought its face was also clean, so it just swaggered（大摇大摆地走）down the street.”

“Einstein, no one can be your ‘mirror’. You have to think for yourself. If you always notice what others say and do, you will never learn.”

Hearing this, Einstein laid down his fishing rod and returned to his room. He decided to pay more attention to his studies and less attention to what his friends were doing. This allowed him to be successful.

A bird sat in a tree and watched a cat eat happily under the tree. “The food must be nice,” it said. “Could you let me have a bite (一口) of it?”

“Sure. You can have a bite or two,” the cat agreed.

“Really? You won’t just try to eat me?” the bird asked in disbelief.

“No. I’m full. I don’t want to eat anything that has bones (骨头) or feathers (羽毛),”the cat said.

“Move a few steps back, just in case,” the bird said. After the cat moved back, it flew down and took one piece of food. Then it flew to the tree and started to eat.

“See? I’m too full to care,” the cat said. “Have some more if you want. ”

The bird thought for a moment. It flew down and got another piece, flying back to the tree to eat it. The cat smiled, “It’s good, right?"

“Could I have a little more, please?” the bird asked. The cat replied, “Help yourself. ”

This time, the bird didn’t fly back to the tree. It ate beside the food. The bird was so hungry that it began to eat quickly. After it finished, the bird said, “Thank you. That was a great meal! I’m so full that I can hardly move!”

As soon as it finished speaking, the cat leapt on the bird and caught it.

“That’s what I was waiting for,” the cat smiled.
