For years I wanted a garden. I'd spend hours thinking of different things I could plant that would look nice together.

    But then we had Mathew， and Marvin， and the twins -- Alisa and Alan， and then Helen. I was too busy raising them to grow a garden.

    Money was not enough. Neither was time. Often when my children were little， one of them would want something that cost too much， I'd have to say，"Do you see a money tree outside? Money doesn't grow on trees， you know."

    Finally， all the children got through high school and college and were off on their own. I started thinking again about a garden.

    Then， one spring morning， on Mother's Day， I was working in my kitchen. Suddenly， I looked out of the window and there was a new tree， planted right in my yard. There were things blowing around on it. Then I put my glasses on and I couldn't believe what I saw. There was a money tree in my yard!

    I went out to look. It was true! There were dollar bills， one hundred of them， hanging all over that tree. There was also a note among them， "Thank you for your time， Mom. We love you!"

    Later， my children bought me tools， ornaments（装饰品）， a sunflower stepping stone and gardening books. A new page started in my life.

    That was three years ago. My garden is now very pretty， just like I wanted. When I go out and take care of my flowers， I don't seem to miss my children as much as I once did. It feels like they're right there with me. Now every year when winter comes， I look out of my window and think of the flowers I'll see next spring in my little garden. I think about what my children did for me， and I get tears in my eyes -- every time.

    I'm still not sure that money grows on trees. But I know love does!

    I was doing some last-minute Christmas shopping in a toy store. A nicely dressed little girl was 1 the teddy bears beside her father 2 she saw a little boy walk in and stop in front of the Pokemon toys. His jacket was obviously too small. He had money in his hand. However, it looked no more than five dollars at most. He was with his father, and kept picking up the Pokemon video games. Each time he showed 3 to his father, his father shook his head, "No".

    Rather disappointed, the boy gave up the video games and chose a book of stickers 4. After they walked away, the little girl ran over to the Pokemon video games. She excitedly picked up one 5 on top of the others, and ran toward the check-out. I picked up my purchases（购买物）and 6 the girl and her father.

    Then, much to the little girl's satisfactory（满意）, the little boy and his father got in line 7 her and me. After the video was paid for and bagged, the little girl handed it back to the cashier（收银员）and said something to her in a low voice. The cashier smiled and put the 8 under the counter（柜台）. I was putting things in my bag when the little boy came up to the cashier. The cashier said, "Congratulations, you're my hundredth customer today, and you win a prize!" and she handed the boy the Pokemon game. The boy could hardly believe his ears. It was, he said, 9 what he had wanted! The little girl and her father had been standing at the doorway, and I saw the biggest and prettiest smile on that little girl I have seen in my life.

    I suddenly understood that the world is not 10 into the strong who care and the weak who are cared for. We must each in turn care and be cared.

At 15:40 on December 9th, 2021, the "space teacher", Wang Yaping, made some experiments in the Tianhe Core Module of the Chinese Space Station.

"Welcome to the ‘Tiangong Classroom!' " said Wang Yaping.

Taking a "spacewalk" is difficult. Ye Guangfu was working hard to walk, but his body floated! Then he tried to turn around but he couldn't. "In space, astronauts are in a weightless environment. So we need to use nearby devices (装置) to move," he said.

The paper flower "blooms". In the "Tiangong Classroom", Wang Yaping made a beautiful water film (水膜). Then she took out a paper flower and placed it on the film of water. The pink flower slowly "bloomed"! "I hope your dreams can bloom in the huge universe!" she said.

"Space Happy Ball" rings fun. Wang Yaping asked the children on the ground to put their ping pong ball in the water. The density (密度) of the ball was less than that of the water, so it floated up. In space, when she put the ping pong ball into the water, it did not float up to the surface. It stopped in the center of the water! "The buoyancy (浮力) disappears in a weightless environment in space so the ping pong ball cannot float (漂浮)." Ms. Wang explained.

Have you ever heard of Zhang Guimei? She is not only an excellent teacher, but also a great woman in {#blank#}1{#/blank#} heart. Because of her efforts, a lot of girls in the mountains have got a good education and achieved a better {#blank#}2{#/blank#}.

Zhang Guimei was born in 1957 in Heilongjiang. She went to Yunnan to {#blank#}3{#/blank#} build the less developed area in China in 1975. Eight {#blank#}4{#/blank#} later, Zhang became a teacher. She found that some girls there couldn't get a good education because of their {#blank#}5{#/blank#} families and wrong ideas. She was so {#blank#}6{#/blank#} about them that she wanted to try her best to change their ideas. Unfortunately, Zhang was {#blank#}7{#/blank#} ill in1997. However, she never gave up and then set up Huaping High School for Girls in 2008. Thanks to Ms. Zhang's help, thousands of girl students have been brave enough to {#blank#}8{#/blank#} out of the mountain s in the past14 years.

As we know, Zhang Guimei has devoted her {#blank#}9{#/blank#} life to her educational work. Also, her experiences have {#blank#}10{#/blank#} many people and made them pay more attention to education for the girls in poor areas. What a great woman she is! She is the very person that I admire most.
