How much do you know about Albert Einstein?

    Albert Einstein, born on March 14, 1879 in Germany, was a great scientist in the world. ①He 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. He once 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, “②热爱是最好的老师。”

    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.

    Dick lived in England. One day in January he said to his wife, “I'm going to fly to New York next week because I've got some work there.” “Where are you going to stay there?” his wife asked. “I don't know yet.” Dick answered. “Please send me your address from there in a telegram (电报),” his wife said. “All right,” Dick answered.

    He flew to New York on January 31st and found a nice hotel in the center of the city. He put his things in his room and then he sent his wife a telegram. He put the address of his hotel in it.

    In the evening he didn't have any work, so he went to a cinema. He came out at nine o'clock and said, “Now I'm going back to my hotel and have a nice dinner.”

    He found a taxi (出租车) and the driver said, “Where do you want to go?” But Dick didn't remember the name and address of his hotel.

    “Which hotel are my things in?” he said, “and what am I going to do tonight?” But the driver of the taxi did not know. So Dick got out and went into a post office. There he sent his wife another telegram, and in it he wrote, “Please send me my address at this post office.”

    Mr. and Mrs. Black opened a small restaurant. In order to attract (吸引) customers, they put a notice in front of the restaurant that said "Meals on the House for Three Days."

    A foreign student who didn't know much English happened to pass by the restaurant on the second day. It was lunch time and he felt very hungry. "Well, here is a restaurant. I am going to have something to eat."

    He walked towards the restaurant when he saw the notice. "American people are really strange. They even eat dinners on their houses. But how can I get up to the top of the house?" he said to himself.

    He looked around and found a ladder against a tree nearby. He started climbing up. But as he reached the top，he heard someone shouting at him.

    "Hey, what are you doing up there?" Mr. Black shouted at him. Next to him was a policeman.

    "Doesn't your notice say? "Meals on the House for Three Days'? Is it just a joke?" the foreign student answered.

    On hearing this, both Mr. Black and the policeman laughed. "Do you know what ON THE HOUSE means? Look it up in the dictionary," the policeman said.

Drawing on a New Friendship

    Last Saturday, I went to the park to draw. When I finished the outline of a girl, a shadow（影子）fell across my drawing.

    "That's not a bad start", said the shadow. "Do you have any finished drawings?" I looked up to see a girl about my age.

    I was displeased that someone was looking at my drawing and interrupted me. "Not bad?" I asked.

    "No need to be angry." The girl handed a sketchbook(素描本)to me." Want to look at my drawings?"

    I felt curious and traded sketchbooks with her. Her sketches of people were okay, but I was really attracted by her drawings of nature, like trees, rocks, and rivers, all done with great detail.

    "Wow！You have some talent," I said. "What's your name?"

    The girl took back her sketchbook and answered, "Emma Thompson."

    "I'm Alice Ruiz, "I said." You draw so well. Are you in an art class?"

    Emma replied, "No. The art class is full, so I have to wait until next term. Besides, you're a talented one. I really find it difficult to draw people, but you make it look easy."

    "I have a great idea！"I said." Let's draw together！You can draw the nature views on one piece of paper while I draw the people on another. Then we'll exchange and finish each other's drawings. That way, both drawings would show off both of our talents!"

    "That's not a bad idea, Alice, "Emma agreed.

    About an hour later, we completed our drawings. I had drawn a boy walking with his dog. Emma had added a path and some flowers. Emma had drawn a beautiful tree, and I had added a girl reading under the tree.

    "This was a fun idea, "I said." Hey, Emma, would you like to meet me here again to draw together?"

    "See you next Saturday, Alice, "Emma said with a smile.

    It started as a game. Wendy and Peter were in River Park. They watched the boats in the river and visited the zoo. They played on the slides and swings. They watched the merry-go-round, but they did not have money for a ride. They ate their sandwiches at a picnic table. Suddenly Wendy jumped up.

    "I know what to do." she said. "Look at all that junk under the tables. Let's pick it up."

    So they picked up paper and empty boxes and cans. They put them in the green cans marked "Litter". Peter's dog Stoopy picked up some paper and ran away with it. Peter called him back and took it from him. Then they taught Stoopy to carry trash for them. They put it in the cans. They worked until there was no trash left on the picnic grounds.

    The next day their friends Mario and Andy came to the park with them. They helped to tidy the picnic grounds again. Then they ran all over the park looking for litter. They tried to see who could find the most. After that, it was a game they played every time they came to the park.

    One day, a man came with a camera. He watched what they were doing. He asked to take a picture for them. Then he took them all for a free ride on the merry-go-round, even Stoopy. The next day their picture was in the newspaper. It said, "Five Litter Lifters at River Park". After that all their friends wanted to be litter lifters. It was the beginning of a club that was a model for others to follow.
