    Heroes of Our Time

    A good heart

    Dikembe Mutombo grew up in Africa among great poverty and disease. He came to Georgetown University on a scholarship to study medicine — but Coach (教练) John Thompson got a look at Dikembe and had a different idea. Dikembe became a star in the NBA, and a citizen of the United States. But he never forgot the land of his birth, or the duty to share his fortune with others. He built a new hospital in his old hometown in the Congo. A friend has said of this good-hearted man: “Mutombo believes that God has given him this chance to do great things.”

    Success and kindness

    After her daughter was born, Julie Aigner-Clark searched for ways to share her love of music and art with her child. So she borrowed some equipment, and began filming children's videos in her own house. The Baby Einstein Company was born, and in just five years her business grew to more than $20 million in sales. And she is using her success to help others — producing child safety videos with John Walsh of the National Center for Missing and Exploited Children. Julie says of her new program: “I believe it's the most important thing that I have ever done. I believe that children have the right to live in a world that is safe.”

    Bravery and courage

    A few weeks ago, Wesley Autrey was waiting at a Harlem subway station with his two little girls when he saw a man fall into the path of a train. With seconds to act, Wesley jumped onto the tracks, pulled the man into the space between the rails, and held him as the train passed right above their heads. He insists he's not a hero. He says: “We have got to show each other some love.”

How Important Is Fashion?

    Is looking fashionable more important than being comfortable? Many people seem to think so, judging by the things they wear. But fashion is not everything. It is more important to be a healthy and good person.

    People go to great lengths to be fashionable. Some people think they have to have a certain body type, so they go on extreme, unhealthy diets in order to change their bodies. In addition, many women wear uncomfortable fashions, such as high-heeled shoes that create blisters（水泡）, tight body shapers that limit blood flow, and sticky false eyelashes. Men and women alike spend time and money on products that change their natural hair color and use hot irons and blow dryers to curl or straighten their hair. Some people spend several hours a day in front of a mirror. Is fashion important enough to spend so much time and effort on changing how you look like?

    If the purpose of fashion is to make a person feel good, it does not make sense that he or she would go through so much discomfort to be fashionable. Fashion should not come first. People should prioritize（优先考虑）being healthy and positive. What people wear does not indicate anything about their personalities. Instead of spending hours choosing a suit, perhaps you should call your friends and do something together! Instead of going on strict diets and starving, why not eat some healthy foods and then exercise? By doing these things, you can keep a healthy lifestyle and truly grow as a person.

    Phil White has just returned from an 18,000-mile, around-the-world bicycle trip. White had two reasons for making this epic journey. First of all, he wanted to use the trip to raise money for charity, which he did. He raised ＄70,000 for the British charity, Oxfam. White's second reason for making the trip was to break the world record and become the fastest person to cycle around the world. He is still waiting to find out if he has broken the record or not.

    White set off from Trafalgar Square, in London, on 19th June 2004 and was back 299 days later. He spent more than l,300 hours in the saddle(车座)and destroyed four sets of tyres and three bike chains. He had the adventure of his life crossing Europe, the Middle East, India, Asia, Australia, New Zealand and the Americas. Amazingly, he did all of this with absolutely no support team. No jeep carrying food, water and medicine. No doctor. Nothing! Just a bike and a very, very long road.

    The journey was lonely and desperate at times. He also had to fight his way across deserts, through jungles and over mountains. He cycled through heavy rains and temperatures of up to 45 degrees, all to help people in need. There were other dangers along the road. In Iran, he was chased by armed robbers and was lucky to escape with his life and the little money he had. The worst thing that happened to him was having to cycle into a headwind on a road that crosses the south of Australia. For 1, 000 kilometres he battled against the wind that was constantly pushing him. This part of the trip was slow, hard work and depressing, but he made it in the end. Now Mr. White is back and intends to write a book about his adventures.

    Some parts of the garden are for the rest of the world to admire. Others are for you to disappear to when you don't want to be found. Of course, that's easy enough to arrange when you have lots of land with space for the kids to run round and cosy "garden rooms" for the adults to enjoy. But when your garden is on the small side, you might think it's a tall order. Well, you're wrong.

    To create a secret garden, people tend to take the routine: surrounding a small garden with high fences and then placing a lawn(草坪) in the middle and borders round the edge. Far from making the most of the area, that just makes it look a lot smaller and more boring. Dividing it up makes much more use of your space and means you can have your practical family area plus a secret garden.

    When you're searching for the perfect secret site within your existing set-up, consider your present favourite spot. A secret garden needs to be special—a complete contrast to the more practical family parts of the garden. Perhaps you take a folding chair down to a quiet corner that gets evening sun; maybe you sit and watch the pond or simply slip out to the patio(露台)with a glass of wine.

    It's quite easy to change an existing favourite feature into a secret place. You could top the patio with a pergola(棚架) pole and plant a grapevine for shade, or position a bench overlooking the pond and plant bamboos to screen it from the rest of the garden.

    The areas you create needn't all to be the same size—or even the same style—but if you're planning a major redesign, take your time and work it out on paper before committing time and money. Then when it's done, you'll really be able to relax and enjoy it.

    The Hong Kong-Zhuhai-Macau Bridge, the world's longest sea-based project, comprises four parts: a 22.9-kilometer steel bridge, two artificial islands, a submerged sea tunnel extending for 6.7 kilometers, as well as leading bridges that connect the bridge to the cities.

    For a bridge project, designers prefer to build all the structure on the ground, and only choose the tunnel when there is no alternative. However, for the HZMB, the most practical design is to integrate bridge, island and tunnel to form a complete cross-sea channel.

    "The Pearl River Estuary （河口）holds a world-level shipping channel. Smooth traffic should be guaranteed. And the location is near the Hong Kong International Airport. With about 2,000 flights taking off and landing at the airport, the bridge cannot be built too high for safety reasons, said Meng Fanchao, chief designer of the project. ^"But you cannot have a submerged sea tunnel without any support. That forced us to build the artificial islands."

    Chinese engineers declared a trail in installing deep-immersed tunnel tubes. There is no model for us to refer to as all the cases are shallow-buried tubes, said Meng.

    "For lack of experience, the installation of the first tube lasted for 96 hours," said Yin Haiqing, deputy manager of the Project Management Department. "Everyone was exhausted when we made it."

    The 6.7-kilometer tunnel is the world's longest submerged sea tunnel.

    Two artificial islands, covering an area of 200,000 square meters, help create a smooth transition between bridge sections and tunnels. Different from traditional island, the engineers put 120 steel cylinders （圆柱）with a 22-meter diameter （直径）into the seabed, make out the shape of an island, and fill the island with soil. It is an innovative way they adopted to build the artificial island, making it firmer, more efficient and friendly to the marine ecology.

    The HZMB provides a fixed link between the two Chinese economic centres Hong Kong and Macau and the mainland of China at Zhuhai.
