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.

    Here is a story told an American general（将军）who was a very important figure in the American army during the First World War. Everybody in the United States knew him and many people wished to have a picture or something of his in their homes.

    Soon after the war, the general returned to Washington. One day he went to a dentist（牙医）and had six teeth pulled out. A week later the general heard that his teeth were being sold in curiosity shops at $5 each. On catch of the teeth there was a label（标签）with the name of the general and words, "Buy these teeth and show them to your friends at home. "The general got angry. He rushed to his office and ordered six officers to go around the city and buy all his teeth.

    The officers went out and visited every curiosity shop in the capital. They were away from the office all day. In the evening they returned and put on the table in front of the general the teeth they had bought. They had collected 175 teeth.

    One day when some government officials were rebuilding a house, they found a mouse hole in a corner and used smoke to make the mice inside the hole come out. A while later they saw mice running out, one after another, but they saw two mice didn't run away immediately. It seemed that one was trying to bite the tail of the other.

    Everyone was puzzled, so they came nearer to take a look. They realized that one of the two mice was blind, and the other was trying to allow the blind mouse to bite his tail in order to pull the blind one with him to run away.

    During the meal time, they started to talk about the two mice. One serious American said, "I think the relationship between those two mice was that of king and guard."

    A smart Frenchman said, "I think the relationship between them was that of husband and wife."

    A Japanese said, "I think the relationship between them was that of mother and son."

    At that moment, one Chinese asked, "Why did those two mice have a certain relationship?"

    Suddenly, they looked back at the Chinese. The American, the Frenchman and the Japanese who had spoken earlier all lowered their heads in shame, and didn't answer.

    In fact, the great love is not built on friendship or blood relationship. Instead, it is based on no relationship.

How long would it take you to run 5,000 m? Li Yiben, 80 years old, ran 5,000 m in 28 minutes and 6 seconds（秒）. 

Li did it in a race in Huainan, Anhui Province on April 3rd. There were six runners in his group. The other five were three men in their 50s and 60s and two women in their mid-30s. Li was the oldest but he finished third. 

"This is tough. I have never worked so hard," said Li after the race. 

Li served in the military（部队）when he was young. In 1968, he left the military and found a new job. Li had to go over 20 km from home to work. That's when he got interested in running. Li ran to work every two or three days. That made him a great runner. After he left work in 1995, Li spent more time running. 

In 1998, Li ran a 100 km marathon（马拉松赛跑）. He ran in the National Masters Athletics Championships（全国大师田径锦标赛）in 1999. One year later, he went to the Asia Masters Athletics Championships in India. In 2001, Li went to Sydney to run in the World Masters Athletics Championships. He won many prizes. 

In the following years, Li kept running in many races. Running plays an important role in his life. "Running makes me feel younger," said Li. 

Taihang Grand Canyon National Forest Park is a natural wonder. It lies in the{#blank#}1{#/blank#} part of Huguan County. There are some sweet springs, silver waterfalls, clear {#blank#}2{#/blank#}and interesting caves there.
