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.

    My friend Bob has a large police dog named Jack. Every Sunday afternoon, Bob and Jack have a walk in the park near their home. Jack likes these walks very much.

    On a cold Sunday afternoon, I go to Bob's home. Bob is happy to see me. At first Jack is happy too. Bob and I talk for a long time. Jack plays with a ball in the room for some time. Then he sits down in front of me and looks at me. I go on talking with Bob. Just at that time, Jack takes my hat and runs out of the room. I go after him to get my hat back. Suddenly, I know what Jack wants to do.

What a clever dog!

    Bill is a smart boy. He can do all the math problems(问题) in his math book.

    One day, on his way to school, he sees a sign of a fruit store. It says: "Apples: Six for five  cents(美分)". Bill knows what to do, so he goes into the store.

    "How much are the apples？" Bill asks the man.

    "Six for five cents."

    "But I don't want six apples."

    "How many apples do you want？"

    "Well, it's not a question of how many apples I want. It's a math problem. If six apples are worth(值) five cents, then five apples are worth four cents, four apples are worth three cents, three apples are worth two cents, two apples are worth one cent and then one apple is worth ZERO! I only want one apple."

    Bill chooses(选择) a good apple and starts to eat it. The man is so surprised(惊讶的) that he can't say a word!

    It's Paul's twelfth birthday today. After breakfast, some of his friends come to see him. They give (给) him many nice gifts. Paul is very happy. At about 9:00 in the morning, they play basketball. They have lunch at McDonald's. In the afternoon, they go to the park (公园).

Paul gets some nice presents from his family, too—a yellow T-shirt from his mother, a pair of sports shoes from his father, a CD from his sister Lucy, a basketball from his grandpa and a book from his grandma.

    How happy Paul is!

 Who's That There?

Stand in front of a mirror and look at it. How much do you really know about the person in it?

It's not an easy job to know ourselves. To help students do this important task, schools across China are providing more classes and activities on self- knowledge. 

Liu Yue, a teacher from Chengdu Yucai Middle School, has recently given her students a useful tool. "It's called the Johari Window, developed by two US psychologists, " said Liu. "It has four areas about one's self: open area(that everyone knows about), hidden area(that only you know), blind spot(that everyone knows except you) and unknown area (that nobody knows). Using this tool, students did a good job seeing themselves through a new lens(透镜). "

"I really want to know about my blind spot, " said eighth- grade r Yang Manfei. "So I did a survey with my friends. " The results showed that Yang easily gets worried and nervous and impatient because of procrastination(拖 延 ). "That's a bad habit I've never realised!" Yang said. 

"I find the unknown area most amazing, " said Sun Boyin. "It means everyone has lots of potential (潜力). " When Sun entered middle school, he was not good at maths. "But I set a goal and did lots of maths exercises. Now I'm much better at maths. The unknown part of my maths ability is getting clearer!" Sun said. 

When it came to the hidden area, most students kept silent. "I'm scared to show my secrets deep down," said Li Yixuan. "Then one classmate stood up and said his favourite cartoon is Tom and Jerry. I thought: Am I brave enough to show my childish hobby? Perhaps not. I want my classmates to see me as a mature(成熟的) person, not a silly kid. But then I realised that I don't find that classmate silly. I think he is brave to be himself. "

"Show yourself and make yourself better — that's the best lesson I learned," Li said.
