Diamonds are considered the most famous and valuable jewel in the world. The precious stone for its great value is believed to be the symbol of wealth. Diamonds were made as a result of great volcanic beat and pressure. When a volcano is active, it sometimes explodes and causes great damage to the nearby towns.

    However, at the same time of such a disaster, diamonds were pushed towards the surface of the earth by a number of great volcanic explosions millions of years ago. Thus, it may be very likely to find a diamond after a volcanic eruption. Besides, diamonds are also found among the sand and stones of certain river beds, and in a few places on the floor of the sea, for they were washed down the mountain sides by the rain.

    Diamonds are very rare. There are not many places that produce such precious things in the world. During the last century adventurers from Europe went to Brazil, because they had heard that there were diamonds in the River Amazon. Many of these early diamond miners died of illness or were lost forever in the great forests. But some returned home rich.

    The earliest known diamonds were found in India many centuries ago. The most recent and exciting discoveries have been made in eastern Russia. But most of the world's diamonds now come from the Congo, from Tanzania-which has the largest diamond mine in the world and also from South Africa.

    Have you ever heard of a great Chilean poet? He was once referred to as the Picasso of poetry. Beloved by Chileans of all classes, he is one of the most widely read and respected poets in history. And this year is the 114th birthday of Pablo Neruda(1904—1973).

    Born with the name Neftali Ricardo Reyes Basolto, he was a tall, shy and lonely boy. He loved to read and started to write poetry when he, was ten. The American poet Walt Whitman, whose framed picture Neruda later kept on his table, became a major influence on his work.

    However, his father did not like the idea of having a poet for a son and tried to discourage him from writing. To cover up the publication of his first poem, he took the pen name Pablo Neruda.

    In 1924 Neruda gained fame with his most widely read work “Twenty Love Poems and a Song of Despair”. Yet his rich experience as a diplomat and exile made him go beyond the theme of love. His work also reflected the political struggle of the left and development of South America. He was awarded the Nobel Prize for Literature in 1971.

    Neruda loved the sea which he saw as creative, destructive and forever moving. He found inspiration in the power and freedom of the waves and the seabirds on the coast. “I need the sea because it teaches me,” he wrote. “I move in the university of the waves.” He loved how the sea forever renewed itself, a renewal echoed（共鸣）in his work.

    Thomas Edison received a patent(专利) for his kinetoscope(电影放映机) on August31, 1887. It was a machine for viewing moving pictures. Edison had hoped to combine his no invention with the phonograph(留声机), which he had invented 10 years earlier. He thought that people would like to watch moving pictures that went along with the sound. He was not able to make them work together. The kinetoscope, however, was a popular attraction by itself. A person looked through small holes in a box-like machine and saw pictures in action. One of the first films made showed a man sneezing.

    A problem with this invention was that only one person could view the moving pictures at a time. By 1891, Edison had invented a projector that showed the film on a screen. Many people could watch together.

    In 1893, Edison built a motion-picture studio. He made over 300 silent films. Most of them were short. That was because the pictures flashed, or shook a lot. It was hard for people to watch more than 10 minutes at a time.

    The first films were mostly of real events. They would show famous people walking somewhere, cars on a street, burning houses, and other news stories. Then comedies and short dramas were made.

    Edison's movie studio closed in 1918. By then other companies were also making films. Better cameras were made. Sound was added. Then color came along. Today, movies are among the most popular forms of entertainment.

    February 14th is Valentine's Day! In China, it is only a day for boyfriends and girlfriends. But my teacher and my friends in America told me that Valentine's Day is a public day.

    This was my first Valentine's Day in America. I didn't understand the customs clearly. Maybe I didn't need to send any gifts. I watched others to see what they did, so next time I can understand.

    On that day, when we began the reading class, Mr. Peters gave every student some chocolates and said, “Happy Valentine's Day!” I was very happy. The teacher gave his students gifts and blessings! I never saw that in China. Maybe American teachers are very different. I didn't buy a gift for the teacher, so I owed a gift to the teacher. Anyway, I want to say, “Thank you teacher, and I'm sorry.”

When we had a break, one of my classmates gave me a Pokemon card. It was very funny. I felt we were children. I thought I owed a gift again, but I felt thankful. It was another gift, but it was from my new classmate.

    When we were moving to our grammar class, suddenly I heard someone calling me, “Shelly!” I stopped. Another classmate who had only been in our class one day gave me some chocolates. She said, “These for you and your friends. Have a good day!” I was looking at her leaving and thinking she spoke Arabic. We were in the same class only one day, but now we are friends. That's very good, but I owed a gift again.

    When I came home, my Chinese friend sent some roses and chocolates. I was surprised and happy because I had never received roses in my past life, but I hoped it was the last gift. I didn't want to owe more gifts.

    Some international languages are widely used for many purposes. Some minority languages will die out and some nations tend to keep minority languages. I reckon that most common used international languages ease our life quality and communication with different nationalities. On the other hand, we need to help improve minority languages.

    There are many languages in the entire world but two or three minority languages die out each year. Some countries try to save dying languages. For instance, Australian Government created a project to save the language and culture of Maori who are Australian aborigines. And there are other projects to keep minority languages such as American Indian language.

    However, the worldwide job market usually requires candidates who can speak English or other international languages. People who cannot speak lingua franca (共通语) could hardly be promoted at work. For example, some companies need an employee who can deal with foreign companies. So most people tend to learn at least one international language that helps them to find a better job.

    Therefore, world needs one common lingua franca that should be spoken in any country. Consequently, one common language should be a required subject in every school. So anyone speaking one common language can travel without worries to any point of the world and trade their products. People will not be forced to learn many languages.

    In conclusion, we should help minority nations to keep their languages for the cultural diversity. To ease the worldwide communication among nations, we should create a common language and provide courses of it. As a result, no one will face a language issue.

    It all started in 2007 when James Bowen, a thirty­something drug addict who survived by playing guitar on the street, found an orange cat sitting in front of the door of his apartment.

    Bowen noticed the cat was wounded. Without hesitation, the young man took him to the Humane Society and spent the little money he had on medicine to heal him.

    Shortly thereafter, the cat, who was healing and feeling much better, began to follow the musician when he left the house. Then one day the cat got on the bus that Bowen took to the place where he worked.

    That's how the cat, who had recently been named Bob, began to accompany his human friend to his musical performances. Bob's mere presence attracted the attention of passers­by. He and Bowen would finish off each song with a high five. Pretty soon, the images of Bob wearing a scarf while sitting on the musician's shoulder, or keeping him company while he played the guitar, began to go viral all over the world.

    Eventually, the news found out about the pair and did a story for the magazine Islington Tribune. It was not long after that when a book agent appeared in their lives and gave them a chance to tell their story.

    By then, Bowen, who had managed to get away from drugs, wrote a novel called A Street Cat Named Bob. He related in great detail how meeting the cat changed him.

    The book soon sold more than six million copies and even spread beyond the borders of the United Kingdom. In fact, it was translated into thirty languages.

    Through all of these changing circumstances, Bob has always been with Bowen—on his shoulder.

    You can't make up a story like this. But life always gives opportunities to those who know how to get hold of them. So if you are ever in a position where a cat has chosen you, don't ignore it. You can't imagine all the good that life may have in store if you decide to accept the proposal.
