Mr Robin（知更鸟）had his house in a tree.
     His four baby robins lived in it. They grew very fast. Soon the house was too little for them.
   “It is time for you to fly,” said Mr Robin.
   “Oh, we can not fly,” said the baby robins.
   “You can, if you try, ” said Mr Robin.
     A robin tried. He flew into a tree.
   “Oh, how interesting!” said the little robin. “I like to fly. See me go!”
     Then the other robins tried.
     In a little while they could all fly.
     The robins could fly, but they could not sing.
   “No, Dad, we can not sing.”
   “You can, if you try. Hear the other birds sing. Look at the pretty flowers and the blue sky. Then you will want to sing. Hear me sing to you. Now sing for me.”
      One little robin sang.
     Then they all sang.
     A little girl came by. “Wow, hear the birds sing!” she said. “How happy they are!”

One day, Meg finds that a button(纽扣) of her coat is lost. She looks forthe button everywhere, but she can't find it. The next day, she doesn't wear that coat to school and feels sad all day. After school, she goes to the clothes shops and wants to buy that kind of clothes. But she feels disappointed.

    Meg tells her sister about that, her sister says, “We can change all the buttons. Then the buttons will be the same.” The coat is beautiful again and Meg feels happy again.

School started again, and soon the ink(墨水)in Tom's spelling book was found. Tom said he hadn't split the ink, but that made it look as if he were lying. Becky almost said Alfred Temple had done it, but she kept quiet. She thought that Tom would tell the teacher about her tearing(撕)his book, so she didn't save him. Mr Dobbins beat him and then Tom went back to his seat。

After an hour Mr Dobbins unlocked his desk and took out his book, Tom looked over at Becky. She looked like a hunted and helpless rabbit. The next moment the master faced the children. There was a long silence, then he spoke, "Who tore this book?"

There wasn't a sound. The teacher searched their faces.

"Benjamin Rogers, did you do it?"

Benjamin said no.

"Joseph Harper, did you?"

Joseph also said no. Dobbins looked at the rows of boys, thought for a moment, then turned to the girls.

"Amy Lawrence?"

A shake of the head.

"Gracie Miller?"

The same sign.

Becky was next. Tom was shaking from head to foot.

"Rebecca Thatcher?"—(Tom looked at her face; it was white with terror)— "did you tear?—no, look at my face—did you tear this book?"

Tom jumped to his feet and shouted, "I did it!"

The children stared(盯着) in surprise at his foolish act.

And when he stepped forward for his punishment, he saw the surprise, the thanks, and the love that came from Becky's eyes.This was enough for one hundred beatings. And he didn't even mind staying for two hours after school, because he knew that Becky was waiting for him outside.

Tom went to bed that night planning some actions on Alfred Temple, for Becky had told him everything. And he fell asleep with Becky's last words to him in his ear, "Tom, you are so great!"

Cai Xuzhe dreamed of flying high when he was young. He was a new face on the Shenzhou-14 team. He spent 12 years as an astronaut（宇航员） getting ready for his first trip to space.

"I am happy and proud but feel more about my duty（责任）," Cai told reporters. Cai and other two team members, Chen Dong and Liu Yang, left the earth on board the Shenzhou-14 spaceship in June of 2022, for a six - month stay in space. They finished the work of building the Tiangong space station.

Cai was born in 1976 in the countryside of Shenzhou City, Hebei Province. He showed interest in planes as a child. When he heard a plane flying past, he ran out and looked at it till it flew away.
