Article: Bethany Meilani Hamilton was born on February 8, 1990 Kauai, Hawaii, where she grew up with two older brothers. Hamilton's parents were both surfers and they started teaching Bethany how to surf at a young age, and she learned quickly with the support of her brothers. By age 8, Bethany was winning first place in surfing contests for her age group. Hamilton began competing more seriously at the age of nine, winning several more competitions in her age group. On October 31, 2003, while surfing with friends near Tunnels Beach, a 14-foot tiger shark attacked her. Bethany said, "My arm was hanging in the water, and it just came and bit me. It kind of pulled me back and forth. But I just held onto my board and then the shark let go." The shark tore off Bethany's left arm just below her shoulder. Hamilton's friends rushed her to the hospital. Bethany made it through several surgeries without infection , and miraculously survived even though she had lost almost 60% of her blood. The doctor said that her athletic training helped her to survive the attack and blood loss. While she was healing, Bethany thought for a while that she might not surf again. She was concerned that it would be much harder to stand up on the board using only one hand and that her balance would be completely off. But with hard work and determination she returned to surfing. She says, "It's hard for me to describe the joy I felt after I stood up and rode a wave in for the first time after the attack. I was greatly thankful and happy inside. The tiny bit of doubt that would sometimes tell me 'you'll never surf again' was gone in one wave !" As for fear of another shark attack, Bethany says that sometimes her heart pounds when she sees a shadow under the water. But she believes that faith provides hope and a future for those who feel down and defeated in their lives. Bethany's popularity and hope for the future led her to partner with World Vision to create "Surfing for Children in Crisis". Bethany hopes that her involvement in the campaign will help provide disabled children from around the world with care, support, and hope.
Answer: Her parents.
Who taught Bethany surfing when she was very young?

Article: America is a mobile society.Friendships between Americans can be close and real, yet disappear soon if situations change.Neither side feels hurt by this.Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while --then no more.If the same two people meet again by chance, even years later, they pick up the friendship.This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending sometimes deeply into both families. Americans are ready to receive us foreigners at their homes, share their holidays, and their home life.They will enjoy welcoming us and be pleased if we accept their hospitality easily. Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time.This is usually the opposite of the practice in our country where we may be _ .Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend.We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine.They will probably expect us to get ourselves from the airport to our own hotel by bus.And they expect that we will phone them from there.Once we arrive at their homes, the welcome will be full, warm and real, We will find ourselves treated hospitably.For the Americans, it is often considered friendlier to invite a friend to their homes than to go to restaurants, except for purely business matters.So accept their hospitality at home!
Answer: Americans will continue their friendships again even after a long break.
Which of the following statements is TRUE according to the passage?

Article: London has become a cycle-friendly zone after the launch of a new bike hire scheme. It has been designed to encourage more people to cycle in and around central London. So how does it work?First you have to sign up to the scheme to be sent a key. The key will unlock one of the bikes, which are kept at docking stations in and around central London. You have to pay an access fee for the key and then you pay as you go, for the length of time you use the bike. Transport for London, which runs the scheme, are hoping to have 6,000 bikes and 400 docking stations in place by the end of the year. The new hire system is hoping to ease traffic jams in London and is expected to create up to 40,000 extra cycle trips a day into the city centre. London Mayor Boris Johnston launched the scheme and said London has been "filled with thousands of gleaming machines that will transform the look and feel of our street and become as commonplace on our roads as black cabs and red buses". However, there have been a few problems since the scheme was launched last Friday. On the first day some people found they couldn't dock their bike properly and their usage of the bike had not registered. Transport for London did admit they had been expecting a few "teething problems" and have said they would not charge for the first day as a "gesture of goodwill". Some other people have criticized the lack of docking stations and locks for the bikes as well as the price it costs to hire the bicycles. Despite the comments, the green-thinking London Mayor still says with certainty, "My crusade for the capital to become the greatest big cycling city in the world has taken a great pedal-powered push forwards."
Answer: To relieve the traffic problem in London.
