An American spacecraft is moving closer to a dwarf planet(矮行星)called Ceres(谷神星). The American space agency's Dawn spacecraft is set to reach the planet-like object in March.
Space agency scientists will then place Dawn in an orbit(轨道) around the dwarf planet. Agency scientists want to know more about ice on Ceres. The spacecraft will gather clues about whether Ceres may have once had conditions to support life as we know it.
Dawn left Earth more than seven years ago on a trip to explore Ceres and another dwarf planet, called Vesta(灶神星). Both dwarf planets are in the main belt of asteroids(小行星), a group of large objects, between the planets Mars and Jupiter.
Marc Rayman is the chief engineer and director of the Dawn mission.
Scientists call Vesta and Ceres "protoplanets(行星) ". Mr. Rayman says they were in the process of becoming full-size planets when, in his words, "their growth was terminated(终止)."
Scientists believe Ceres is made of rock, and covered with ice.
The Dawn mission is based in Los Angeles, California. Scientists there send second-by-second commands to the spacecraft. They direct its every move, including telling it what pictures to take. Dawn will make a map of the dwarf planet. It will also try to discover how Ceres' surface has changed.
Carol Raymond is the deputy principal investigator(副首席研究员) of the project. He says Dawn made an unexpected discovery while orbiting Vesta.
"Instead of being bone dry, which we expected, there were patches on the surface of Vesta that showed significant amounts of water bound in the rocks and possibly even free water that could have flowed on the surface in the past."
She says that if Earth's water came from wet worlds like Vesta and Ceres, then life could have developed there, too.
If Dawn finds that the environment of Ceres could have supported life, scientists may seek to explore the dwarf planet with other scientific instruments.
Dawn will gather information about Ceres until the middle of 2016. It will then continue to orbit the small planet.

O. Henry was a pen name used by an American writer of short stories. His real name was William Sydney Porter. He was born on September 11, 1862, in Greensboro, North Carolina.
As a young boy he lived an exciting life. He did not go to school for very long, but he managed to teach himself everything he needed to know. When he was about 20 years old, O. Henry went to Texas, where he tried different jobs. He first worked on a newspaper, and then had a job in a bank, when some money went missing from the bank, O. Henry was believed to have stolen it. Because of that, he was sent to prison. During the three years in prison, he learned to write short stories.
After he got out of prison, he went to New York in 1902 when Porter's most prolific(多产的)writing period started. While there, he wrote 381 short stories. He wrote a story a week for over a year for the New York World Sunday Magazine. He wrote mostly about New York and the life of the poor there.

Porter traveled with Richard to Austin in 1884, where he met Athol Estes, then seventeen years old and from a wealthy family. On July 1, 1887, Porter married Athol.

Porter married again in 1907, to childhood sweetheart Sarah (Sallie) Lindsey Coleman, whom he met again after revisiting his native state of North Carolina.

Every year on April 1, April Fools’ Day is celebrated in many countries around the world. In France, it’s called Poisson d’Avril or “Fish of April.” In Scotland, the holiday is often called “Gowkie Day.” In Iraq, the holiday is called Kithbet Neesan or “April Lie.”
History experts say people have celebrated April Fools’ Day for a long time. Some believe the tradition comes from the ancient Romans more than two thousand years ago. It was a day of playing games and pretending to be someone else.
Others say the day for fooling began in France in 1564, when King Charles changed the yearly calendar（日历）. He moved New Year’s Day from April 1 to January 1. Many people did not know about the change because of communication problems back then. Some people continued to celebrate New Year’s Day on April 1. Other people called them April Fools and played jokes on them.
In the United States, April Fools’ Day is just a day of joking and playing tricks on friends. These kinds of jokes are also called pranks. These jokes typically end in the prankster shouting “April Fools’!”
Simple pranks, like telling a friend a funny lie or making prank phone calls, are still common. But, major companies also get in on April Fools’ Day fun in a much bigger way. A few years ago, on April 1, Starbucks announced it was introducing new coffee cup sizes -- Plenta and Micra. The very large cups, bigger than a human head, remained useful for customers even after finishing all that coffee. According to Starbucks, the cups could be used as a rain hat, a pot for plants, or a lampshade（灯罩）.
It did not take long for customers to catch on to the prank!

Union is strength. Whenever you’re faced with difficulties, and cooperation plays an important part in getting you out of trouble.
There was a time that I was so proud that I overlooked my classmate, refusing to work together with them.Therefore, it was no doubt that I was left alone,suffering from loneliness and failure. Unluckily, a teacher impressed on me the value of cooperation.From then on, I learned to help others and turn to my friends for the help whenever I had difficulty finish a task on my own. Surely cooperation makes a great difference. Now I am getting on well with his friends.
My experience has teach me that only if we place great stress cooperation can we go beyond ourselves. As the saying go, “United we stand; divided we fall.”
