Mr. Black was over fifty years old. He sometimes made some mistakes in his work, and he lost his work. So he had 1 time every day to do something. Then he often met his old friends under a big tree. They had drinks there and talked 2 anything they liked.

One day, some old men were sitting together again and talking about young people in this world. They all agreed that the old people were 3 than young people. Then one of the old 4 said that young men were stronger than old men. 5 of them agreed that this was true, 6 Mr. Black didn't. He said, "No. I am as strong now as when I was a young man." His friends were surprised 7 what he said. "Well," said Mr. Black, "Near my house there is a big stone. When I was a young man, I used 8 to move it, but I couldn't because I was not 9. I am an old man now, and when I try to move it, I still 10. So, I am as strong as when I was young."

    One day Einstein1 in the street in New York. His friend 2 him and says to him," Einstein, you should buy a coat. Look, how 3 your coat is!”

    But Einstein answers, "It doesn't 4. Nobody 5 me here."

    After a 6 years Einstein becomes a famous scientist. But he still 7 the old coat.

    His friend meets him again and asks him to buy a 8 one.

    But Einstein says,” I needn't buy a new one. 9 knows 10 here.”

    My father was a self-taught mandolin(曼陀林琴) player. He was one of the best players in our town. He could not1music, but if he heard a tune(曲子) a few times, he could play it. When he was young, he was a2of a small country music band. They played at local dances and played for the local radio station on a few occasions.

    At home Dad often took out his mandolin and played for the family. We three children sang along.3played the mandolin like my father. He could4your heart with the music that came out of that old mandolin. He seemed to shine when he was playing. You could see his5in his ability to play so well for his family.

    But Dad had to find another6in a factory later because the money he made at the band wasn't enough to7the family. Unluckily he had an8one day and lost one finger. He couldn't play as9as before. From then on, every time we asked him to play, he would make up excuses to 10 down our request. However, we missed his performances so much.11, he agreed and said, "Okay, but remember, I can't hold down the strings (琴弦) the way I12 to."

    When he played the old mandolin, it carried us back to a13, happy time in our lives. Dad was that kind of man,14 was what he was doing all his life. If he could give 15 to others, he would, especially his family. He was always there, sacrificing(牺牲) his time to see that his family had enough in their life.

Waste sorting (垃圾分类) has come. It's so important to us humans. We do waste sorting before throwing rubbish away. We are happy to see some fine examples. However, it is not easy for everyone to do this. Some people may spend so much time deciding the kind of the rubbish. Luckily, the twin sisters front Beijing developed an app (应用程序) to help solve the problem.

The app is easy. When users need to throw away their rubbish, they open the app first. In the app, they can find the names of different rubbish. Then, they choose a kind of rubbish in the app, and the right rubbish bin (箱) will open. The app is also helpful. It makes use of speech recognition (语音识别) technology. Then users can just speak out the name of the rubbish, and the rubbish bin will open. 

In fact, waste sorting isn't difficult, but we need some time to get used to it. Of course, technology can help us to do it better.
