There was a very rich man named John. He gave a great puzzle (谜语) to the people in the town.

    In his house, he had a very large room. "If anyone of you can fill my room in one day, I will give you 100,000 dollars." Everyone in the town wanted to try.

    The first man tried to fill the room with stones. At the end of the day, he was very tired, but the room was still empty.

    The second man tried to fill the room with wood. He worked all day, but the room was not full. "That room is too big," he said. "No one can do this."

    The third man said, "I can do it. It's easy." Everyone laughed. They thought he could not do it. Then, the man went to the park and played all day. His friend said, "Why are you playing? You should be working." The man said, "I can do it. Don't worry." At 8 o'clock at night, the man came to the room with a small bag. The rich man said, "Haha……that bag is too small. It doesn't fill the room." The man reached into the bag and took out a candle. He lit (点亮) the candle and said, "You see, the whole room is filled with light!"

    Are you trying to live a healthy life? The following tips may sound strange, but they can really help you.

    Exercise when you are tired

    After a long and tiring day of study, an offer to exercise might not sound like a good idea, but it should. In fact, physical activities can provide you with the missing energy. Research shows that exercising for just 30 minutes can make you feel good!

    Write by hand to help the brain be active

    Although writing something using a computer is faster, it is much better to remember the whole thing by writing it down by hand. When you read a handwritten text, naturally it's easier for your brains to remember the information.

    Spare more time for yourself

    By sparing the time for yourself and just being alone for a while, you can have a chance to think and get to know yourself better. And you won't behave impulsively (易冲动地).

    Drink hot drinks on a hot day

    What cools more on a hot summer morning, cold water or hot water? A study shows that the hot water does make people feel cooler. When you are drinking something hot, the body will feel the change in temperature and increase the perspiration (流汗), which helps you cool down!

Albert Einstein(1879-1955)

Early Life

    Albert Einstein was born on I4th March,1879 in Germany. He was an extraordinary (非凡的)person since he was born. Einstein wasn't able to speak a word until three. He was curious(好奇的)and imaginative. He loved watching things carefully and asked a lot of questions about them

His questions were often hard to answer for teachers.

Schooling

    Einstein started school in 1885. Though he did well in maths and science, he failed in many subjects like history geography and languages. He was not the teachers' favourite. He didn't enjoy going to school. Einstein finished high school in Switzerland and entered a university in Zurich. He graduated（大学毕业）as a teacher of maths and physics in1900.

Scientific Work

    After graduation. Einstein worked at the Patent Office. He spent much time studying physics. By 1909, Einstein had become a top scientist. Though he became successful in the field of science, he still put great effort in scientific research. Finally, he won the Nobel Prize for physics in 1921.

Later life

    Einstein kept at his research until he died in 1955. Scientists studied his brain(脑)after his death to see if there was anything special about it. However there was no conclusion(结论).

    Today, many famous scientists still think Einstein is the smartest man in the world.

    Like many high school graduates, Maggie Doyne didn't go straight to college. She decided to travel and arrived in western Nepal in 2006. A war had just ended there and left many children living on the streets. They were often forced to work at hard physical jobs for little money.

One day, while walking down a country road, Doyne saw a little girl breaking up rocks. She soon learned that 7-year-old Hima sold the rocks to support her family. With deep sadness, she decided to pay Hima's tuition(学费) for school. Encouraged by the changes in the child, Doyne thought, "If we can help one child, why not 10？"

    Doyne felt that the street children's greatest need was a home. She found a piece of land for sale and bought it with $5,000 she saved from years of babysitting (当临时保姆). In 2008 the Kopila Valley Children's Home was set up. With the help from the community, another goal was reached in 2010—the Kopila Valley School. Over 350 children now attend the school and over 50 live in the home.

    Today, Doyne lives in the home and is "mum" to the kids.

    O. Henry, a famous American writer of short stories, was born in North Carolina in 1862. O. Henry was a pen name. His real name was William Sydney Porter. When he was a young boy, he did not go to school for long because of being born in a poor family, but he tried to teach himself everything he needed to know.

   When he was about 20 years old, O. Henry went to Texas. There he tried different jobs. He first worked on a newspaper, and then had a job in a bank. But he got himself into some trouble. Some money went missing from the bank. O. Henry was believed to have stolen it, so he was sent to prison(监狱). During the three years in prison, he learned to write short stories. After he got out of prison, he went to New York and went on writing.

   He wrote mostly about New York and the life of the poor there. People liked his stories, because almost all of them finished with a sudden change. This made the readers surprised.
