Conor Grennan was unwilling to be a volunteer(志愿者). The 29-year-old American was not sure if he had the skills or a strong feeling for it.However, he went to work at an orphanage(孤儿院) in Nepal. His first thought was to make people impressed.

    "I thought that if I volunteered just once. I could retell the story over and over," Grennan said in a Huffington Post article.However, his three-month stay it the orphanage turned into in unusual experience. It was 2004 and Grennan had given up his job to begin a year-long around-the-world trip, His first three months were spent in Nepal.

    When he arrived in the village, he knew nothing about the children or the local culture. When he opened the gate of the Little Princes Children's Home, he was faced by the excited children.

    The young American ended up caring for 18 children. He later discovered that they were trafficked(被拐卖的)children. So he walked through the mountains with great difficulty to find the kids' families, "I started walking with photos of the kids." he told the Reuters reporter. "I would show up in villages and show photographs around. I went with 24 photos, and I found 24 families." At the same time, he put his heart into Nepalese culture.

    Grennan said, “Volunteering is the single best way to see how the rest of the world lives.”

    He also encouraged others to do what he had done. He believes that volunteering needs only making decisions to show up.

    Grennan's fight against child-trafficking has changed him. His book, Little Prince, came out last week.

    The sharing economy has grown in recent years to include everything from apartment sharing to car sharing to community tool sharing. Since 2009, a new form of sharing economy has been appearing in neighborhoods throughout the US and around the world— Little Free Library. The libraries are boxes placed in neighborhoods from which residents can withdraw (取出) and deposit (存入) books. Little Free Libraries come in all shapes and sizes. Some libraries also have themes, focusing on books for children, adults, or tour guides.

    In 2009, Tod Bol built the first Little Free Library as a gift to his mother, who was a devoted reader. When he saw the people of his community gathering around it, exchanging conversation as well as books, he knew he wanted to take his simple idea further. “I think Little Free Libraries open the door to conversations we want to have with each other,” Bol said.

    Since then, his idea has become a movement, spreading from state to state and country to country. According to Little FreeLibrary.org, there are now 18,000 of the little structures around the world, located in each of the 50 US states and 70 countries in Europe, Africa and Asia.

    The Internet has helped to spread Little Free Libraries. But an Atlantic article says the little structures serve as a cure for a world of e-reader downloads. The little wooden boxes are refreshingly physical and human. For many people, the sense of discovery is Little Free Libraries' main appeal. “A girl walking home from school might pick up a graphic novel that gets her excited about reading; a man on his way to the bus stop might find a volume of poetry that changes his outlook on life,” says the Atlantic article. “Every book is a potential source of inspiration”.

    Charlotte Heffelmire was home in Vienna,Va.,for Thanksgiving break from the Air Force Academy when she saw that her father had gotten stuck under the pickup truck he'd been working on.

    "I was on my back,face up,and I was trying to get some brake lines when apparently the jack（千斤顶）slipped and fell down on me,"her dad,Eric Heffelmire,told WUSA9.Gasoline spilled（溢出）and caught fire,and he knew he was in trouble."I thought they 'd be pulling out a dead body later in the evening."

    After his struggling for 10 minutes,his barefoot teenage daughter came running into the garage."I felt the weight shift,and I said,'You almost got it.'and then it was just UGHHHRRR,and suddenly I'm pulled out,"Eric told NBC4.

    Even Charlotte,120 pounds and 5-foot-6,isn't sure where her power came from."It was some crazy strength, "she told WUSA9.

    Realizing the burning truck could set her house on fire at any moment,Charlotte jumped into the truck and drove it out of the garage."I didn't want the entire house to explode with the truck,so I started the truck,put it in four-wheel drive,and managed to drive it with three wheels,"she said.

    Then she went inside the house to grab her baby sister and got her grandmother out of the house too."I just did what I had to do,so I don't feel like a big hero or anything,"Charlotte said.Her local fire department,Fairfax County Fire and Rescue,felt differently,awarding her the Citizen Lifesaving Award.

    Here is some must-know information from a handbook on how people behave in doing business in some countries.

In Brazil

    Brazilians are warm and friendly. They often stand close when talking and it is common for them to touch the person on the shoulder. People often greet each other (particularly women) with light cheek kisses. Schedules tend to be flexible, with business meetings sometimes starting later than planned. But to be safe, be on time. Meals can stretch for hours—there's no such thing as rushing a meal in Brazil. Lunches also can start in the mid to late afternoon. Brazilians are social, preferring face-to-face communication over mails or phone calls.

    In Singapore

    Singaporeans shake hands when they meet and often also greet each other with a small, polite bow. Business cards should be offered and received with two hands. Arriving late is considered disrespectful. So be on time. Efficiency(效率) is the goal, so meetings and dealings often are fast-paced. Singaporeans are direct in their discussions, even when the subject is about money. Rank is important and authority is respected. This determines both people interact in meetings. For example, people avoid disagreeing outright with someone with a higher rank.

    In the United Arab Emirates

    In the UAE, status is important, so the most senior or oldest should be greeted first with their titles. The handshake seems to be longer than elsewhere. So, do not pull away the handshake. Women should cover themselves when it comes to dress. Men also tend to be covered from neck to elbows(肘部) and down to the knees. People do not avoid entertaining in their homes, but they also hold business meals at restaurants. Touching or passing food or eating with your left hand is to be avoided. When meetings are one-to-one, if your host offers you coffee, you should refuse. It might seem odd, but it is a cultural tradition. Coffee should only be accepted if it is always set out or presented.

    In Switzerland

    The Swiss tend to be formal and address each other by last name. They also are respectful of private lives. You should be careful not to ask about personal topics. Punctuality (守时) is vital, something that comes from a deep respect for others' time. Arrive at any meeting or event a few minutes early to be safe. They also have clear structure in their companies. Higher-ups make the final decisions, even if others might disagree. Neat, clean dress is expected. The Swiss follow formal table manners. They also keep their hands visible at the table and their elbows off the table. It is polite to finish the food on your plate.

    Have you ever heard of the Coral Sea? It is home to an amazing variety of turtles, sharks, whales, dolphins, large fish, birds, corals, plants, and many other species. Many of these species are endangered elsewhere in the world, but still survive in the healthy environment of the Coral Sea.

    The Coral Sea is a large series of coral reefs located off the northeast coast of Australia. This area is three times larger than Australia's famous Great Barrier Reef, which the Coral Sea borders.

    The Coral Sea is one of the few coral reef environments that have remained largely undamaged by over-fishing, oil and gas exploration and pollution. However, statistics show that coral reefs around the world are disappearing five times faster than rainforests. It is very likely that in the near future the Coral Sea will face the same threats to its existence.

    The Australian government is currently looking at options for protecting the Coral Sea but has made no decisions. Environmentalists are pushing for laws to declare the Coral Sea area a marine protected area, which will mean a large “no-take zone” for fishermen, a no-exploration zone for gas and oil companies and a no-dump zone for pollution, possibly making the Coral Sea a marine park larger than any other in the world.

    We can write letters to Australian leaders, Australian environmental protection agencies, and Australian friends, to let them know that people worldwide support this protection of the Coral Sea. To lose this last great marine wilderness world would be a loss for the whole world.

    The idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play has an important part in keeping you healthy.

    Use "the best medicine" to treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.

    Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it's for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.

    Anyway, adding humor, laughter, and play to our life will influence us mentally, physically and socially and bring us many advantages. So we should make full use of humor, laughter and play to make our life more active, interesting and happier.
