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.

    Jack Ma, whose Chinese name is Ma Yun, became the richest man in China, when the company he founded floated on the stock market last year with a value of around ￡140 billion. Here are some interesting stories about him.

    ⒈"Beer" was the first word that Jack Ma searched for on the Internet

    In 1995 Ma made his first trip to the US and used the Internet for the first time. After searching for "beer" and then "China", he saw that no results came up relating to China. He decided to set up a Chinese website一the seed for Alibaba had been sown.

    ⒉Jack Ma applied to study at Harvard 10 times and was rejected (拒绝) each time

Ma failed the entry exams for colleges in China three times and was also rejected for many jobs in China, including one at KFC. He was turned down by the Harvard 10 times after applying.

    ⒊Jack Ma learnt English by giving tourists free guides一every day for nine years.

    Limited resources meant it was difficult to learn English when Ma was young. However, he found that he could learn the language by giving tourists free tours around his hometown of Hangzhou一something that he did during his teenage years every morning for nine years. He found everything they said and did was so different from what he had been taught at school and by his parents, which opened his mind.

    ⒋Jack Ma named his company Alibaba because it's a globally known story

Ma simply wanted his company to have a global and interesting name, and realised that Alibaba is a story known across the world and it begins with A, appearing top of lists.

    The company was founded in 1999 and since then has grown from 15 employees to more than 30,000. Ma hopes to keep expanding Alibaba outside of China.

    Google's new camera, called Clips, is a small, smart device. It comes with a case that has a clip (夹子)，but it's not designed to be worn on your clothing. Most interestingly, it uses artificial intelligence to take photography out of your hands so it can capture moments on its own.

    This roughly 2-inch by 2-inch camera, with a three-hour battery life and Gorilla Glass for toughness, is intended for candid moments, like when a child does something cute that may happen too quickly for you to pull out your smartphone.

On board the Clips device, it uses machine learning algorithms (计算程序) to help capture scenes. Those algorithms include face recognition. “Once it learns that there's a face you see frequently, it'll try to get nice photos of those faces,” said Juston Payne, the device's product manager. And they also want it to recognize facial expressions, which involved “training it to know what happiness looks like”. The Google team also trained it to recognize what not to shoot — like when a child's hand is over the lens, or if it is tossed in a dark purse.

    The only way to see the images is by connecting the camera with your phone, as it has no screen for viewing or editing.

    Were people concerned it could seem strange? Yes, Payne admitted. But they said they addressed that by making it obvious what it is. A green light on the front signals that it is on. Besides, unlike a camera meant to monitor your home, it is not connected to the Internet.

    “This product is only possible because of the way that silicon has advanced” Payne said, noting that it was only in the past year or so that they could squeeze the technology down into a device this size. Going forward, we're likely to get more assistance from the artificial intelligence packed into our apps and gadgets.

    I'll never forget the day when Mary came into my office and said, I am too old to learn how to use a computer. I shook my head. Here was a woman who had raised 6 children and who had made great progress in her career telling me that she was too old to learn something new. I told her that I always believed people were never too old to learn.

    Mary followed my advice and did learn how to use the computer. Now, she is retired and leading a very active life volunteering in her community( 社区 ),using her computer skills and helping anyone that needs help.

    When she was in her sixties, one day she called me and said she had played the piano for others all her life, and now she was going to make a CD of her own. My mind flashed back to the day when she told me she was too old to learn. You can imagine my surprise and delight.

    To produce the CD, she had a lot of things to learn. It was not just sitting at the piano and playing. She had to research the songs, learn about copyright(版权),and learn about marketing. It was pretty amazing for someone who once said she was too old to learn. And finally she made it. Now she has her own CD-Mixed Blessings.

    Most of you probably have heard about some people who have gone back to university in their seventies and have also graduated. They are on their way again to charging themselves with a new skill and a new attitude towards life. The point is you are unable to learn anything at any age if you believe you are too old. On the contrary, you can achieve anything at any age if you believe you can.

    There are two types of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.

    People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied. By their remarks, they sour the pleasure of society, offend (hurt) many people, and make themselves disagreeable everywhere. If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied. The intention of criticizing (批评) and being disliked is perhaps taken up by imitation (模仿). It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes. I hope this little warning may be of service to them, and help them change this habit.

    Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck. Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success. Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrongdoings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others. If they do not, it will be good for others to avoid any contact (接触) with them. Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels.

    A new study suggests that patients with breast cancer who take additional vitamins during chemotherapy(化疗) treatment may face increased risks.

    Researchers said the use of dietary supplements(补充剂) that increase levels of antioxidants, iron, vitamin B12 and omega-3 fatty acids appeared to lower the effectiveness of chemotherapy. Researchers reported their findings in the Journal of Clinical Oncology.

    Christine Ambrosone is the head of cancer prevention and control at the Roswell Park Comprehensive Cancer Center in Buffalo, New York. She said, "From this study and others in the literature, it seems that it may not be wise to take supplements during chemotherapy."

    "It's thought that antioxidants might interfere with the ability of chemotherapy to kill cancer cells," Ambrosone said.

    Some doctors have been advising patients for a number of years not to take antioxidants during chemotherapy. "But there was no strong empirical data for that recommendation," Ambrosone said.

    So, Ambrosone and other researchers decided to study whether supplement use might affect chemotherapy's effectiveness. They looked for evidence in an earlier study on diet, exercise, lifestyle and cancer results.

    In the earlier research, people who took part were asked about their use of supplements at the beginning of and during treatment, and about their lifestyle, diet and exercise. The researchers studied 1,134 patients who filled out the surveys and followed them for a median of six years.

    The researchers searched for possibilities that might increase the risk of the disease reappearing or of death. They found that patients who took any supplements at the beginning of and during chemotherapy were 41 percent more likely to have their breast cancer return than those who did not. In addition, the supplement takers were 40 percent more likely to die later on compared to patients using no supplements. The supplements included vitamin A, C and E. Those taking vitamin B12 and iron supplements were at greater risk of cancer returning, the researchers said.
