There was once a captain who loved money so much that he cheated his sailors at the end of every voyage and took their wages.

    On the last day of one voyage, the ship was in a small port. It was winter time, and the sea was very cold, so the captain said to his sailors, "If one of you stays in the water during the whole night, I will give him my ship. But if he comes out before the sun appears, I shall get his wages."

    The sailors had heard about the captain's cheating, so they didn't trust him. But then one of them, who thought that he was cleverer than the captain, said that he would do it. He got into the water, and, though it was very cold, he stayed in it. When it was nearly morning, some fishermen lit a fire on the shore about half a mile away.

    "You are cheating," the captain said to the sailor. "The fire's warming you."

    "But it's half a mile away!" said the sailor.

    "A fire's fire," answered the captain. "I have won."

    The sailor came out of the water, and said, "Perhaps you think that you are clever because you have won my wages, but you can't cook a chicken."

    "I can," answered the captain.

    "If you cook this chicken," said the sailor, "I shall work for you without wages for seven years, but if you can't, you will give me your ship."

    The captain agreed, took the chicken and said, "Where's the fire?"

    "There it is," answered the sailor. "On the shore."

    "But it's half a mile away," said the captain angrily.

    " A fire's fire, you said," answered the sailor. "If it is enough to warm me in the water, it is enough to cook your chicken."

    When I found out I was moving to India, it was beyond a nightmare. It was something I couldn't even imagine. The impression I had of India were only based upon a few summer visits to my grandparents, filled with heat, pollution and dirt. Even though I was only six years old, I know this would be a complete change from my comfortable life in Maryland.

    During my first six months in India, my expectations were met almost exactly. I hated my new apartment; I missed my school and friends back in Maryland, and I was sick of all the dirty marketplaces that filled the streets of New Delhi.

    After those six months were over I finally realized that I was going to be in India for a while. I knew that I had to start making the most of my new life. It was then that I became completely involved in my school. My school, the American Embassy School, was filled with international students: Europeans, Australians, Chinese, and Americans just like me. But they all welcomed me with open arms. It was amazing to be among such diverse students, who had such incredible experiences to share.

    Now, when I look back at my time in India, all I can think about is how fortunate I am to have had such a wonderful experience. My move to India not only allowed me to see a completely different side of the world, but I was also able to establish unbreakable bonds with so many interesting and amazing people. Even now, after quite some years, I am still in contact with my closest friends from the American Embassy School. I cannot even imagine what I would be like without having lived in India. I would have missed out on meeting so many extraordinary people, and I would be a completely different person today.

    Baby girls make their way to dolls as soon as they can crawl, while boys will head for the toy cars,  a study has shown. The findings, the first to show consistent differences in very young babies, suggest there is a biological basis to their preferences.

    Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 babies aged nine months to 36 months. They were allowed to choose from seven toys. Some were boys' toys - a car, a digger, a ball and a blue teddy.  The rest were girls' toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded.

    Of the youngest children (nine to 14 months), girls spent much longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two-and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents' view on which toys were more appropriate for boys or girls, and the children's choice.

    Dr Brenda Todd said: “Children of this age are already exposed to much socialization. Boys may be given ‘toys that go' while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts（本能）, while girls prefer warmer colors such as pink, the color of a newborn baby.”

When I lived in Spain, some Spanish friends of mine decided to visit England by car. Before they left, they asked me for advice about how to find accommodation. I suggested that they should stay at "bed and breakfast" houses, because this kind of accommodation gives a foreign visitor a good chance to speak English with the family. My friends listened to my advice, but they came back with some funny stories.

"We didn't stay at bed and breakfast houses," they said, "because we found that most families were on holiday." I thought this was strange. Finally I understood what had happened. My friends spoke little English, and they thought "VACANCIES" meant "holidays", because the Spanish word for "holidays" is said "vacaciones". So they did not go to the house where the sign outside said "VACANCIES", which in English means there are free rooms. Then my friends went to the houses where the sign said "NO VACANCIES", because they thought this meant people who owned the house were not away on holiday. But they found that these houses were all full. As a result, they stayed at hotels.

We laughed about this and about mistakes my friends made in reading other signs. In Spanish, the word "DIVERSION" means "fun". In English, it means that workmen are repairing the road, and that you must take a different road. When my friends saw the word "DIVERSION" on a road sign, they thought they were going to have fun. Instead, the road ended in a large hole.

English people have problems too when they learn foreign languages. Once in Paris when someone offered me some more coffee, I said "Thank you" in French, I meant that I would like some more, however to my surprise the coffee pot was taken away! Later I found out that "Thank you" in French means "No, Thank you".

    More than 40 percent of the species that help with pollination (植物传粉) are under threat due to the polluted environment. So some researchers have been searching for ways to protect the bees and other crucial pollinators while some engineers have thought perhaps an army of robotic pollinators could keep humans well-supplied in these foods. A team of researchers has recently designed a small drone capable of pollinating flowers. They tested their device on the large, pink flowers of lilies. And it worked.

    Exciting as this success was, it is only the first step. The team has yet to figure out how to apply the concept on the massive scale. Could a fleet of robo-pollinators replace the bees?

    “Although the answer isn't a straightforward no, it would be a challenging leap to go from this one little drone pollinating one large flower to an army of drones spreading across fields of crops,” says Scott Swinton, an agricultural economist at Michigan State University.

    “The successful pollination was fascinating,” Scott Swinton says, “but the device itself might damage the flowers. I wonder how you make sure you're not doing more harm than good to flowers when you have a drone.”

    “Furthermore,” he points out, “a lily is a particularly easy flower for a drone to pollinate. To make this more broadly applicable for smaller and more complex flower structures, the drones would need to be particularly agile.”

    Still, Joshua Campbell, an expert at the University of Florida, says “Pollination systems are extremely complex and will always require insects. There is no substitute for bees.”

    “As for the technology itself, it is a promising new development in existing drone technology,” he added. Yet he still sees some hurdles ahead before drones can be applied on a large scale.

    MacArthur's love for sailing dates back to when she was just four years of age, when she first got the opportunity to have a try. "I'll never forget that feeling as a kid of setting foot on a boat for the first time," MacArthur said. "It's kind of struck me that this boat had everything we needed to take us anywhere in the world. And as a child, that opened up everything," she explained how it felt like the "greatest sense of freedom".

    This experience lighted a passion within MacArthur. She knew then that she wanted to sail around the world. She had no idea how to achieve it — growing up in the countryside, it wasn't the most obvious career path — but she knew that was what she wanted to do at some stage. So, she acquired knowledge and saved up for years to seek a career in sailing. She would have potato and beans every day for eight years so that she could save up to buy the right equipment. By reaching certain financial goals and asking technical questions about sailing, MacArthur felt as though she was getting closer to her ambitions.

    "When you know where you're going, you can actually get there — even if it seems impossible. The impossible could be possible and aiming high is not necessarily such a crazy thing to do." And it seems that MacArthur's drive to become a sailor went beyond her expectations. At the age of 24, she started to receive media attention after participating in the Vendee Globe, a single-handed non-stop yacht (游艇) race that goes around the world. She came in second place. Some three to four years later, MacArthur chose to sail for 71 days and 14 hours, covering more than 26,000 miles during the course of her journey. This led to MacArthur scoring a new world record in 2005, as the fastest person to sail around the globe single-handedly. While this record has since been surpassed, MacArthur is still considered as Britain's most successful off shore racer.
