Galaxy saw a man and a woman who communicated with the sign language at the train station when she was on the way home one evening. She noticed that the woman asked the man for the direction. He told her that he did not know. Galaxy decided to help them. She had learned the sign language when she served as a volunteer in the deaf and mute（聋哑）school. Then she showed the woman the direction and left her email address to them in case they needed her help later.

    She received an email from that man the next day. Kazrim was his name. Galaxy replied his mail sincerely.

    They both started chatting online soon after and began seeing each other. Although they only communicated with the sign language, it never bothered her.

    Galaxy was fond of him gradually. Obviously, Kazrim was the same too. He presented Galaxy with a bunch of sunflowers and asked her sincerely, “Are you willing to be my girlfriend?” Galaxy was pleasantly surprised. She requested him to give her some time to persuade her parents.

    As she had expected, her parents were very angry after they had learned of their love story. Galaxy explained, “Kazrim is an excellent and a very optimistic person. He has a very positive attitude towards life and work. He cares for others always. He is 100％ better than the normal. Moreover, the mute is still a human. He should possess a perfect and wonderful love. ”

    Her parents asked to see him, then. The very worried Galaxy took Kazrim home a few days later. When they were on the train, Kazrim told her, "I'm going to tell your parents I'll be looking after you well with all my life!” Galaxy was deeply moved.

    As soon as they had entered the house, Galaxy introduced him to her parents. She said, "This is Kazrim.” Just right after her speech, an unbelievable thing happened. Kazrim threw the gift away and held her in his arms tightly.

    He said, “YOU CAN TALK?” It was the same question that Galaxy wanted to ask, too.

    The four people were shocked all of a sudden. As a matter of fact, Kazrim always believed that Galaxy was a mute and he still fell in love with her deeply.

    You get on an almost-empty bus, but the next passenger decides to ignore all the empty seats to sit right next to you. While you are waiting in line at the supermarket, the next customer stands just behind you shouting into his phone.

    These are attacks of the personal space invaders(侵略者). Though preferences for personal space differ from culture to culture, we Britons do love our independence and personal space.

    As the British customs website Debrett has said, as a British person, somebody standing too close may make you “focus less on what somebody is saying than on how close they are to you”. Simple acts like putting an arm around someone you don't know that well may seem friendly in China, but they can make us very uncomfortable. The ediplomat.com website explains: “The British are not back slappers (拍打者) or touchers and generally do not show affection (喜欢) in public.”

    Being a British person around people from other countries can therefore be full of problems. People from many European countries such as France and Spain kiss each other on the cheek when they meet, yet to us this seems too friendly and “touchy-feely”.

    Simple matters like how close others stand can be problems to Britons who want to keep their own personal space. Giving advice on how to behave around a British person, Debrett's says that “if you can feel the warmth of their worried breath upon your face, then you're standing too close”.

    So, are British people unfriendly? No. The ediplomat.com website explains that we are not as “indifferent” as we may seem, but “very friendly and helpful to foreigners”. However, we do have different ideas about our own space to many people from other countries. Just let us know if you're going to come any closer than arm's length, and you'll be fine!

    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.

    Why do you go to the library? For books, yes--but you like books because they tell stories. You hope to get lost in a story or be transported into someone else's life. At one type of library, you can do just that--even though there's not a single book.

    At a Human Library, instead of books, you can “borrow” people. Individuals volunteer as human “books” and participants in the event can “read” the book--meaning they would have a one-on-one conversation with the volunteer and share in a dialogue about that individual's experience. “Books” are volunteers from all walks of life who have experienced discrimination (歧视) based on race, religion, class, gender identity, age, lifestyle choices, disability and other aspects of their life

    For a certain amount of time, you can ask them questions and listen to their stories, which are as fascinating and as attractive as any you can find in a book. Many of the stories have to do with some kind of stereotype. You can speak with a refugee (难民), a soldier suffering from PTSD, a homeless person or a woman living with HIV. The Human Library encourages people to challenge their own long-held beliefs-to truly get to know, and learn from someone they might otherwise make a quick judgment about.

    According to its website, the Human Library is “a place where difficult questions are expected, appreciated and answered.” It provides the opportunity for the community to share and understand the experiences of others in their community.

    The Human Library Organization came to be in Copenhagen, Denmark in 2000. Ronni Abergel, his brother Dany, and some colleagues hosted a four-day event during a major Northern European festival, hoping to raise awareness about violence among youth. After the success of this event, Abergel founded the Human Library Organization, which has been growing ever since.

    Though there are a few permanent human libraries, most aren't places at all, but events. Though many do take place at physical libraries, you don't need a library card—anyone can come and be part of the experience. There have been human library events all over the globe, in universities and in pubs, from Chicago to Tunis to Edinburgh to San Antonio.

The stories these "books" tell range from fascinating to heartbreaking and everything in between. And that's the very point of the organization--to prove that no person can be summed up in just one word. It seeks to show people that you truly can't judge a book by its cover—or by its title or label.

    Audrey Hepburn won an Academy Award as Best Actress for her first major American movie，Roman Holiday，which was released in 1953．But she is remembered as much for her aid work as for her acting．

    Born in Belgium in 1929，Audrey's father was British and her mother was Dutch．Audrey was sent to live at a British school for part of her childhood．During World War II，she lived and studied in the Netherlands. Her mother thought it would be safe from German attacks．Audrey studied dance as a teenager and during college when she returned to London after the war．But she realized she wasn't going to be a ballerina （芭蕾舞女演员）．So she began taking acting parts in stage shows．Later she began to get small parts in movies．

    But it was Audrey Hepburn's move to America that brought her true fame．In 1951 she played the character"Gigi"in the Broadway play of the same name to great critical praise．Two years later，Roman Holiday made her a star at the age of 24．

    Audrey made more than 25movies．Among her most popular roles was Holly Golightly in Breakfast at Tifany's in 1961．Three years later she played Eliza Doolittle in My Fair Lady．

    She was married two times and had one son by each husband．In 1989，the UN Children's Fund named Audrey a goodwill ambassador．She travelled all over the world in support of UNICEF （联合国儿童基金会） projects．The UN agency said she was a tireless worker．She often gave 15interviews a day to gain money and support for UNICEF projects．

    Audrey Hepburn often said her loyalty to UNICEF was the result of her experiences as a child during World War II．She said she knew what it was like to be starving and to be saved by international aid．She was a goodwill ambassador until her death in 1993from colon cancer．

A kind of blue dye (颜料) called folium had been widely used to paint pictures on the pages of manuscripts (手稿) created in the Middle Ages. But long ago, this watercolor fell out of use.

"Manuscripts are an important part of the cultural works of art in the Middle Ages," said scientist Maria in an email to CNN. "Color is a basic feature of these manuscripts. To let ancient manuscripts. keep a good condition for future generations, we sometimes need to repaint their inside pictures through the ancient dye — like folium — that was once used in these manuscripts. But everyone who knew how to prepare folium had died long ago. So 'I led a team to study this dye."

Her team turned to books from the 1400s and found one that described the plant that was its source. It is a tiny plant with silvery-green leaves. Days later, the scientists reached a village in south Portugal, where nobody knew this little plant. However, after carefully going through a plenty of different plants growing there, the scientists finally raked out the plant they wanted and brought some back to their laboratory.

Back in the lab, the scientists produced the dye with the help of an ancient text on colors. The text has clearly described the ways to make it. "It's cool to have done that work of looking in the historical records and traveling back in time," says Casadio, who was not part of this study. It recreates an ancient process. By making the dye, the scientists could study its chemistry without experimenting on priceless delicate (易损的)  works of art, she points out.

Now, the researchers don't know the dye's stability(稳定性)and its ability against the environment that may wear and break it down over time. "To know such information is necessary if we desire to make these colors last long enough," Maria said. "So our study will continue."
