My sister and I grew up in a little village in England. Our father was a struggling lawyer, but I always knew he was special. He never criticized us, but used praise to bring out our best. He'd say, "If you pour water on flowers, they flourish (茂盛). If you don't give them water, they die." I remember as a child I said something unkind about somebody, and my father said, "Any time you say something unpleasant about somebody else, it's a reflection of you." He explained that if I looked for the best in people, I would get the best in return. From then on I've always tried to follow the principle in my life and later in running my company.

    Dad's also always been very understanding. At 15, I started a magazine. It was taking up a great deal of my time, and the headmaster of my school gave me a choice: stay in school or leave to work on my magazine.

    I decided to leave, and Dad tried to sway me from my decision at first, as any good father would. When he realized I had made up my mind, he said, "Richard, when I was 23, my dad persuaded me to go into law. And I've always regretted it. I wanted to be a biologist, but I didn't pursue my dream. You know what you want. Go fulfill it."

    As it turned out, my little publication went on to become Student, a national magazine for young people in the U.K. My wife and I have two children, and I'd like to think we are bringing them up in the same way Dad raised me.

    Many of the world's famous cities are known by some special names. Paris is known as the "City of Light". Hong Kong is the "Wall Street of Asia". One small city in Pennsylvania may be the sweetest place on Earth. That is town of Hershey, which is known as the "Chocolate Town". It is named after Milton Hershey, the founder of the largest chocolate factory in the world.

    Milton Hershey built his first candy factory in the early 1900s. At the time, Hershey was developing a technique for milk chocolate. Eventually he succeeded. Hershey was also the first to produce individually wrapped chocolate bars. His factory grew and produced more and more types of chocolate. To this day, Hershey's chocolate factory is the largest in the world. Hershey used his success to give back to the community. He built a town around the factory for his employees. He gave streets fun names like Chocolate Avenue. He built schools, parks and shops. This generous man gave millions of dollars to charity. He built an amusement park with rides, trains for children and a swimming pool. Over the years, the town grew. People from near and far came to visit this special town, whose beauty and fame continue to attract lots of tourists. Every year close to three million tourists visit the Chocolate Town.

    Today visitors to the city can enjoy a variety of attractions and activities. The Hershey chocolate factory offers tours. Visitors can learn all about chocolate and how it is made. A gift shop sells all kinds of chocolate and toys made to look like chocolate. Even if you don't buy a souvenir, there is one thing that is impossible to forget: the wonderful aroma of fresh chocolate everywhere. In this special place even the streetlights are shaped like chocolate.

    Another attraction is the Hershey Hotel. It has an unusual mineral spring where guests can enjoy a variety of special treatments. The treatments all have one thing in common: chocolate.

    Discovering Tasmania

    The island of Tasmania a place of natural beauty and has more than 2,000 km of walking tracks and 18 national parks. If you go on a tour, you'll discover a wild and beautiful place where the people are friendly and the food is delicious. If you don't like walking, there are other tours you can choose from including a river cruise(巡游) and cycling. You can also enjoy fishing, sailing or sunbathing on the beach.

    The Tarkine coast is located in the northwest of Tasmania. It's such a wild and remote(偏僻) area that you can easily complete your walk without seeing anyone apart from the members of your group and your two guides. The area contains the largest rainforest in Australia which is home to more than 50 endangered species. It is also home to many Aboriginal Heritage Sites. During your tour, you'll come across rivers, mountain ranges, waterfalls, wildlife and long wild beaches.

    Tour Itinerary：

    After breakfast, you continue deeper into the rainforest, passing some of the tallest trees in the world as you go, and stopping for lunch and then camp in the evening.

    Day 3：

    The exciting part of today's tour is the Tarkine Falls, a beautiful 15­metre waterfall.

    Day 4：

    You can stay at the camp and bathe in the Tarkine Falls, or you can go for a walk for more fantastic views of the forest.

    Day 5：

    After a last journey through the forest, you are picked up at about 4：00 p．m. and you arrive in Launceston at around 7：00 p．m.

    It is good to get in touch with your inner child from time to time, and obviously some people are willing to pay big money for the chance to do so in a proper environment. A Brooklyn-based adult preschool is charging customers between $333 and $999 for the chance to act like a kid again.

    At Preschool Mastermind in New York adults get to participate in show—and—tell, arts—and—crafts such as finger paint, games like musical chairs and even take naps. The month-long course also has class picture day where the adults are expected to have a field trip and a parent day.

    30-year-old Michelle Joni Lapidos, the brain behind the adult preschool, studied childhood education and has always wanted to be a preschool teacher. She's always on the lookout for new ways to get people in touch with the freedom of childhood. A friend encouraged her to start the mastermind course instead.

    According to Candice, her blogger friend, Preschool Mastermind gives adults a chance to relearn and master the things that they failed to understand as children. "I realized all the significances of what we learn in preschool," said founder Michelle Joni, "People come here and get in touch with their inner child. It's magical. We are bringing ourselves back to another place, another time with ourselves when we are more believing in ourselves, more confident and ready to take on the world."

    "One person's here because they want to learn not to be so serious." Michelle said. "Another's here to learn to be more confident." She explained that most of the classes were planned. However, Joni added that while the planned activities were fun, it was often the spontaneous(自发的)moments that attracted students. "It's the things you don't plan for, the sharing between friends and learning from each other."

    Dogs are our best friends. That's especially true after a disaster, such as an earthquake. When buildings fall down, search and rescue dogs help find trapped people. Dogs' amazing noses can pick up the smell of survivors. Now scientists have developed an electronic tool that does the same thing. It's taking smell detection(探测) to a whole new level.

    The new invention is a sort of electronic nose, which can detect extremely low levels of many compounds(化合物) from people's skin. This isn't the first time engineers have developed such an object. Earlier models, however, have been bulky and expensive. They could not detect low levels of target compounds either. The new one is inexpensive and small enough to fit inside hand-held equipment.

    The electronic nose can detect extremely slight smell of more than one compound at the same time. "Being able to do this, in such a small object, is the significant discovery," says Sotiris E. Pratsinis, Professor of Process Engineering&Materials Science at the Swiss Federal Institute of Technology in Zurich. His team tested it in special spaces. They were like the small spaces where people might be trapped. Chemicals given off by the volunteers built up inside. The electronic equipment detected those compounds at unbelievably low levels.

The results were good news for the research team. But they may be not for our four-legged friends, who could soon be out of a job. "Ideally, this technology could replace search and rescue dogs," Pratsinis says.

    Stephen Taylor, an electrical engineer, agrees that the new technology has some benefits over dogs. Still, he thinks it may be too soon to have our trusty friends retire. He suspects, "I foresee that such an object could add to the fine work done by the dogs." Taylor also pointed out some potential limitations of the new invention. "E-noses are useful, but can be very likely to be affected by unstable readings and interruption," he says.
