As I walked along the Edgware Road, I felt as though the world was closing in on me. All the sounds I take for granted, had gone. I had entered a world of silence. This unsettling experience occurred a few weeks ago when I agreed to go deaf for the day to support the work of the charity Hearing Dogs for Deaf People, for which I am an ambassador.

    When I managed to take a cab to the office of my manager, Gavin, I couldn't hear what the taxi driver was saying to me. Conversation was impossible. Then, when I reached the office, I had to ring the intercom five times as I couldn't hear a response.

    Everybody said I was shouting at them—I simply wasn't aware of how loudly I was speaking as I couldn't hear my own voice. Gavin kept telling me my phone was ringing, but I didn't realize. I was too busy trying to concentrate on reading his lips. And when he tried to tell me a code to put into my phone, I had to keep asking him to repeat it, more slowly. Eventually he lost his patience and snapped at me: “Just give me the phone!” I was shocked.

    People couldn't be bothered to repeat themselves, so they kept trying to do things for me that I was perfectly capable of doing myself. I felt I'd lost control.

    Being deaf for the day was extraordinarily tiring. I had to work so hard to “listen” with my eyes, get people's attention and use my other senses to make up for my lack of hearing. It was a huge, exhausting effort.

    Until that experience I didn't realize how much I took my own hearing for granted, or the sorts of emotions and experiences deaf people go through. If a deaf person asks you to repeat something, never think: “It doesn't matter.” It does matter.

    Last week I took a journey deep into space, to the end of the solar system, and was pulled into a black hole. Then I took a trip to Brazil and experienced surviving an airplane crash in the jungle. After that, I joined some divers and went to the bottom of the ocean to see strange blind creatures that have never seen sunlight. For a break, I took part in some car racing and then skied down some of the most difficult mountains in the world. I ended my travels by meeting face to face with a dinosaur, the terrible T-Rex, and survived the experience!

    I did all this in one great day at Futuroscope. Opened in 1987, Futuroscope is one of the largest space age parks in the world. This science and technology-based theme park in France uses the most advanced technology. Its 3-D cinemas and giant movie screens provide brand new experiences of the earth and beyond. Visitors can get close to parts of the world they have never experienced, going to the bottom of the ocean, flying through the jungle or visiting the edges of the solar system. The amazing, up-to-date information together with many opportunities for hands-on learning makes the world come to life in a completely new way for visitors. Learning centers throughout the park let visitors try their own scientific experiments, as well as learn more about space travel, the undersea world and much more.

    I bought tickets for myself and my friends at the park's entrance, but tickets are also available online. Futuroscope is not only for indiviudals, but is also the perfect mix of fun and learning for class outings. Classes or other large groups that let Futuroscope know their plans in advance can get the group admission rate. For anyone coming from out of town, Futuroscope has many excellent hotels, most of which provide a shuttle service to the park. If driving, Futuroscope is within easy reach of the freeway. Plan your trip well before starting, since Futuroscope has so many shows, activities and great souvenir shops that it is difficult to see them all. Come ready to walk a lot—be sure to wear some comfortable sneakers or other walking shoes!

    One day, when I was working as a psychologist（心理学家）in England, an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me. “This boy has lost his family,” he wrote. “He is understandably very sad and refuses to talk to others, and I'm very worried about him. Can you help?”

    I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn't have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically（同情）

The first two times we met, David didn't say a word. He sat there, only looking up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon—in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.

    Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company（陪伴）. But why did he never look at me?

    “Perhaps he simply needs someone to share his pain with,” I thought. “Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.

    “It's your turn,” he said.

    After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times, about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.

Maybe I gave David something. But I also learned that one…without any words—can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.

    Life often requires people to join in unpleasant situations. Rather often, these unpleasant situations do not happen on their own, but happen because of other people's actions and words. Fortunately, there are useful ways to deal with conflicts(冲突).

    The best way to solve a conflict is not to let it happen. Nothing useful comes out of a conflict. It is a total waste of time and energy for both sides and thus everyone should try his best to prevent conflict. To do this, you will need to learn the points of view your potential opponents (对手) share and the benefits of understanding people around you.

    If the conflict has already arisen, one of the best methods to settle disagreements is to treat the situation with humor. It does not mean, however, that you must ignore（忽视） your opponent's arguments and make jokes about them; it means that you should be in a friendly atmosphere, saying difficult-to-express things with a bit of humor. Humor will help you reduce anger and re-think problems to make them look easier to settle, and set your opponent's mind to working on a problem with you, not against you. This way, a conflict can become an opportunity for building a greater connection between you and your opponent.

    If the situation turns verbally abusive (恶语中伤), put a stop to it. Firmly but calmly state: "You're very angry right now and you're saying things you don't mean. I'm going to excuse myself. We can talk again after you calm down." Then leave the room or ask them to leave.

    Right in front of the Minneapolis Central Library, a row of green hikes sits parked in a special stand. Each hike is designed with the logo "Nice Ride" the name of the city's bike-share program.

    Nice Ride bikes are a lot like the library books that people come here to borrow. To rent a bike, you simply use your membership card at a Nice Ride bike station. Members can rent one of 1, 200 bikes from 138 stations throughout Minnesota's largest city. People use the Nice Ridebikes to go to work, to go out on business, or just to enjoy the city's many bike paths.

    The rise of bike-share programs like Nice Ride is encouraging more people than ever to choose biking over driving. Skyrocketing gas prices and concerns about the environment have also gotten people to dust off their bike helmets, pump air into flat tires, and hit the road.

    Why ride? Not only is biking good exercise, but switching from a car to a bike also reduces the amount of pollution in the air. Carbon dioxide, a greenhouse gas linked to climate change, is one of the many polluting substances that come out of a car's tailpipe.

    Bike-share systems are found around the world in cities like London, Paris, Barcelona, and Melbourne, Australia. The largest program—with 70, 000 bikes—is in Wuhan, China.

    To make roads friendlier to non-motorists, the U. S. Department of Transportation has invested more than a billion dollars in cycling and pedestrian projects in recent years. The money went toward building thousands of miles of on-street bike lanes and bike-and pedestrian-only passages called greenways.

As a young girl growing up in France, Sarah Toumi dreamed of becoming a leader who could make the world a better place. Her passion to help others was awakened when, from the age of nine, she accompanied her Tunisian father to his birthplace in the east of the country during holidays. There she organized homework clubs and activities for children. Toumi witnessed first-hand the destructive effect of desertification. "Within 10 years rich farmers became worse off, and in 10 years from now they will be poor. I wanted to stop the Sahara Desert in its tracks." A decrease in average rainfall and an increase in the severity of droughts ( 干 旱 ) have led to an estimated 75 percent of Tunisia's agricultural lands being threatened by desertification. 

Toumi recognized that farming practices needed to change. She is confident that small land areas can bring large returns if farmers are able to adapt by planting sustainable crops, using new technologies for water treatment and focusing on natural products and fertilizers (肥料) rather than chemicals. 

In 2012, Toumi consolidated her dream to fight the desert. She moved to Tunisia, and set up a programme named Acacias for All to put her sustainable farming philosophy into action. "I want to show young people in rural areas that they can create opportunities where they are. Nobody is better able to understand the impact of desertification and climate change than somebody who is living with no access to water." 

By September 2016, more than 130, 000 acacia trees had been planted on 20 pilot farms, with farmers recording a 60 percent survival rate. Toumi estimates that some 3 million acacia trees are needed to protect Tunisia's farmland. She expects to plant 1 million trees by 2018. In the next couple of years, Toumi hopes to extend the programme to Algeria and Morocco.
