You may know the English letters A, B and C. But do you know there are people called ABC? You may like eating bananas. But did you know there is such thing as a “banana person”? How strange! Are these people from “another earth”? No. They are just Chinese people like you and me.

    ABC means American-born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a “banana person”. A banana is yellow outside and white inside. So, when a person is a banana, he or she is white inside-thinking like a Westerner and yellow outside-looking like a Chinese.

    Do you know why? Usually, ABCs know little about China or the Chinese language. Some of them don't speak Chinese. Also, they are not interested in Chinese politics.

    But if ABCs cannot speak Chinese, can we still call them Chinese people? Yes, of course. They are Chinese. They are overseas (海外的) Chinese. These people may be citizens(公民) of another country like the US, Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents were from China. They all have black eyes and black hair. But they are not Chinese citizens. They are not people of the People's Republic of China. For example, we all know the famous scientist C. N. Yang (杨振宁). He got the Nobel Prize for Physics in 1957. Chinese people love him. But he is an American citizen.

The least-visited countries in the world

    It's every traveler's dream — a corner of the planet still undisturbed by tourists. And obviously, such places do exist. The United Nations World Tourism Organization lately reported the four least-visited countries globally.

    Liechtenstein (69,000)

    The sixth smallest country in the world is also one of the most undiscovered.

    Lying between Austria and Switzerland, Liechtenstein is an outdoor enthusiast's playground. It's the only country in the world to be totally in the Alps and a summer destination for hiking and cycling and snow-covered skiing perfection in winter, for those who can afford it.

    French Guiana (199,000)

    French Guiana is the least-visited country in South America, with some of the world's most diverse plant and animal life.

    While there is much to attract tourists to the area, not least its miles of jungle, the construction is in need of some attention.

    Montserrat (9,000)

    Once a popular holiday spot, this Lesser Antilles island has never quite recovered from a series of natural disasters. Hurricane Hugo in 1989 hit 90 per cent of the island and in 1995 the Soufriere Hills volcano erupted.

    These days, its volcano is now actually one of Montserra's main attractions, together with its beautiful beaches. Visitors can also go diving in its clear waters.

    Comoros (24,000)

    This collection of islands in the Indian Ocean near Madagascar serves as the perfect destination for those who want to get away from everyday city life.

Comoros offers beautiful volcanic scenery, fruitful forests, and remote sleepy towns. There are even some of the best undiscovered reefs(礁) just waiting to be explored by divers.

    Why can't some people even get an inch of what they dream of becoming? Blame it on pure dreaming and lack of surrounding goals for achieving their dreams.

    Setting goals is very significant part of accomplishing and positive actions. It is like scaling（攀爬）a 200 feet construction and marking in the early hours on what feet you would like to reach at this specific period.

    People who set goals literally generate a map of their goal settings in life, marking where they should start, where to study a bit, and where and when to end. Once this map coms into being, it allows the map drawer to check where he is in the scheme（安排）of things and whether or not he is making some planning that will take him closer to his goals.

    By surrounding goals, people will know how they are doing and what they should be doing to get their goals or dreams in life. They will know if they can relax or if they have to double their efforts when they are falling short of what is expected of them.

    Goal surroundings means a person's proactive in dealing with challenges that may affect his plans. Being proactive means one is able to outline possible difficulties that may occur as well as the solutions to these difficulties. By doing this, a person is not easily scared or defeated when challenges occur because he has already prepared for them. He knows they can happen and he has prepared a solution or strategy when that time comes.

    Setting goals will enable people to track their progress in whatever hard work they set out to do. It will help people become more confident in themselves and more motivated to get their plans.

    I graduated in 1941 and of course got caught in the war. In 1945 I was out, twenty-one years old, a soldier through 35 bombing missions, and at the University of Washington taking creative writing courses, something I'd looked forward to all through the Air Force.

    I'd started writing when I was nine and writing seemed to be the only thing I'd ever be able or want to do. My teacher was a new man named Grant Redford, a very good short story writing teacher and a sad man. He was from Montana and had been connected with the old Rocky Mountain Review. I think it became the Western Review but I'm not sure and I don't bother to look it up. I'm afraid I was never much of a student for Redford. My stories were hopelessly self-indulgent(任性的); on and on about my personal problems, without form, without development, and without even any good writing.

    However, I did write humor in those days and had no trouble getting it published in the campus magazine, though I'd hate to see it now. Mostly my writing was used to get myself attention, to satisfy a terrible personal interest in self-admiration, and it wasn't until I concentrated all my efforts on poems that I was to realize the only real reward of writing, that special way you feel just when you've done something you like. That's far more satisfying than seeing your name in print, good reviews, praise or applause after a reading. And more lasting.

    British children generally learn how to ride a bike at a young age. I am an exception to that rule. It's not my dad's fault—he tried to teach me. I remember cycling around the neighborhood. To be honest, though, I never saw the appeal. One of my earliest memories is falling from my bike and into some spiny(多刺的) plants. I definitely didn't want to repeat that.

    So I stopped learning. My dad wasn't going to waste his time teaching someone who didn't want to be taught. Time passed and I accepted that I couldn't ride a bike. It never affected my life in high school because I lived close enough to walk.

    I never felt like I was missing out until I couldn't go on a bike ride with friends in Byron Bay because I was only confident that I could go on a flat surface in a generally straight line. So when the opportunity came up to bike the wall of Xi'an, I wanted to prove to myself that I could do it and make up for missed time. So, with a friend who is very patient, I got on the bike. Instantly nothing came flooding back to me, I had absolutely no idea how to start! "Push off with one foot hard" was my instruction. It sounded simple enough but it just would not happen. Until something clicked and suddenly I was off, going in a straight line on a flat surface and managing to avoid the Chinese tourists who obviously found exaltation on my face.

    At 22 years old, I finally learnt how to ride a bike, and nothing can hold me back.

    Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean - energy competition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world.

    Engineers and governments have been toying with the idea since at least 1925. But none of the suggested projects has materialised. Price is one objection. A study thought that tidal energy might cost between ￡216 and ￡368 ($306 - 521) per MWh of electricity by 2025, compared with ￡58 - 75 for seagoing wind turbines (轮机) and ￡55 - 76 for solar panels. Environmentalists also worry that any plant would change the tides, making life harder for wildlife.

    An engineer called Rod Rainey thinks he has a way around both problems. He plans to replace the conventional turbines of previous plans with a much older technology. Specifically, he plans to span (横跨) the river mouth with a line of water wheels. This is a design that dates back to the early days of the Industrial Revolution. Examples can be found fixed to the sides of old watermills (水磨).

    But there would be nothing old - fashioned about Mr Rainey's wheels. Thirty metres high and sixty wide, they would be made from ordinary steel. Two hundred and fifty of them, along with the supporting structures, would be floated into place and secured to the seabed, creating a line 15km long. Together, they could supply power at an avenge ate of 4GW. That is about as much as two biggish nuclear power stations would manage. Substituting one of the wheels with a set of locks would provide a shipping channel about twice the width of Panama Canal, permitting upstream ports such as Avonmouth and Cardiff to continue operating.
