How much do you know about Albert Einstein?

Albert Einstein, born on March 14, 1879 in Germany, was a great scientist in the world. He was strange because he hated haircuts and new clothes. He believed in peace. All his life, he hated war. However, his most famous idea, E = mc², helped create the world's most dangerous weapon (武器). Many people think he was the smartest person in the world. But Einstein said that he thought like a child with many questions and unusual ideas.

What did he like?

Einstein liked learning sailing(帆船运动). He sailed in small boats all his life.  Heonce joked, "Sailing is the sport that takes the least energy!”

When Einstein was a child, his mother made him take violin lessons. At first, he didn't like the violin. But then he learned to love music and became a good violinist.

Later, he said, “Love is the best teacher.”

Why is the sky blue?

In 1910, Einstein asked a question which many children often ask, “Why is the sky blue?”After his careful research, he answered the question like this: “It's because light is made up of many colors including blue. When light travels to Earth, gas particles(气体微粒) spread the blue light all over the sky.”His answer is true in physics.

    An old lady in a plane had a blanket（毯子）over her head and she did not want to take it off. The air hostess spoke to her, but the old lady said, “I have never been in a plane before, and I am frightened. I am going to keep this blanket over my head until we are back on the ground again!”

    Then the captain came. He said, “Madam, I am the captain of this plane. The weather is fine, there are no clouds in the sky, and everything is going very well. ”But she continued to hide.

    So the captain turned and started to go back. Then the old lady looked out from under the blanket with one eye and said, “I am sorry, young man, but I don't like planes and I am never going to fly again. But I'll say one thing,” She continued kindly, “You and your wife keep your plane very clean!”

    A famous teacher was speaking to the students at our school. He began his lesson by holding up a ¥100 bill. Then he said to the three hundred students, “Who would like this ¥100 bill?” The students began to put up their hands at once.

    Then he said, “I am going to give this ¥100 to one of you, but first, let me do this.” He then made the bill into a ball. Then he said, “Who wants it now?” The hands went back into the air.

    “Well,” he said, “What if I do this?” and he dropped it on the floor and stepped on it. He picked up the dirty, crumpled bill and said, “Who still wants it?” Hands went back into the air.

    “My friends,” he said, “you have learned a valua­ble lesson today. No matter (无论) what I did to the money, you still wanted it because it did not go down in value (价值). It was still worth ¥ l00!”

    Many times in our lives, we are dropped, crum­pled, and stepped on by the chances we take and the things that happen to us. We feel as if we are worth nothing. But remember, no matter what has happened to you, you will never lose your value: you are always valuable to those people who love you. Your value doesn't come from what you do or whom you know, but WHO YOU ARE.

    You are special and valuable. Don't ever forget it!

    It all started at the beginning of the fifth grade. At first, Carmen wasn't really sure what was happening. In class, she had to squint (眯着) her eyes to see the blackboard clearly. She had to do the same thing when she read street signs, or when she watched a movie.

    It wasn't long before Carmen found herself squinting all the time, but she didn't want anyone to know that. One day, she asked for a desk closer to the blackboard. Her teacher asked if she had trouble seeing the blackboard. Carmen shook her head, but she knew she couldn't pretend(假装) much longer.

    At home, she had to sit closer and closer to the television while watching her favourite shows. Her mother noticed that and said, "Tomorrow I'm calling the eye doctor to get an appointment for you." Three days later, Carmen had" new glasses and the doctor told her to wear them all the time. Carmen frowned in the car the whole way home.

    "All of the kids at school will think I'm a nerd." she said.

    "You look just as beautiful with those glasses on as you do without them," her mother smiled and said. But Carmen didn't believe her.

    The next day, Carmen kept the glasses in her pocket as she walked into the schoolyard. She avoided her friends and stood alone, feeling unhappy. Suddenly, she heard her friend Tracy shout. Carmen ran over. "What's wrong?" she asked.

    "My silver ring is gone!" Tracy cried. "It's very special and I can't lose it!"

    Carmen could tell that Tracy was very sad. They all looked for the ring in the grassy area of the playground.

      ▲   She took the glasses out and put them on. She caught, her breath. Everything looked so different! So clear! She looked down at the ground and a glimmer of silver caught her eye. It was the ring.

    "Here it is. I've found it!" She handed it to Tracy.

    "Thanks, Carmen. I never thought we'd find it," Tracy paused. "Hey, I didn't know you wore glasses. They look great!"

    Carmen had forgotten that she was wearing the new glasses. "Thanks," she replied shyly. As they walked back towards the school building, two more girls from her class complimented (赞美) her on her glasses. Carmen smiled. "Maybe wearing glasses won't be so bad after all," she thought.
