    I had been in the city for some time and was coming home. I missed my boat and decided to travel on an old ship. I knew that it would not be a comfortable journey but I had no time to wait for another boat.

    Hardly had we left the port when I saw the dog Gulliver, the captain's favourite dog, for the first time. What a big dog it was! I had never seen one that could frighten me so much!

    On the third day the ship caught fire. Nobody tried to put it out. The ship began sinking and all the men rushed to the life-boats. I saw no chance of getting away in a boat. Suddenly I remembered there was a life-raft on the ship. I had no time to lose, so I immediately rushed towards the raft and pushed it overboard.

    In jumping down onto the raft I hurt myself badly and was unconscious for some time. When I came to, I found there was no sign of a life-boat. Every man who had been on board the ship must have gone down with her. I was the only one who was saved.

    The I saw Gulliver was coming fast towards the raft. He struggled a long time before he managed to get onto it. I wanted to push him back into the water but did not dare to move. The dog shook himself, went to the other end of the raft and lay down. I didn't dare to sleep that night. I must watch him. In the moonlight I could see his eyes were open. He was watching, too.

    Thomas Cheatham had planned to study Latin during his time at Hebron High School in Texas. But when he learned that the school district was going to offer a Mandarin(普通话) class, he quickly changed his mind.

    "I thought Mandarin would be more beneficial than Latin," said Cheatham, who is now in his second year of studying the language.

    He speaks Mandarin to order food at Chinese restaurants and can read social media posts from his Chinese-speaking friends. While it's a difficult language to master, the high school junior, who plans to study computer engineering, thinks it will be important for his career. "Chinese is a good language to know, especially with China becoming a growing power," he said.

    Many experts agree that proficiency(熟练) in a language spoken by a billion people worldwide will give American students an edge in the global economy.

    "People are looking at China as our next economic competitor, and interest in Mandarin is growing fast," said Marty Abbott, director of the American Council(议会) on the Teaching of Foreign Languages. "We're seeing it in all parts of the country."

    Abbott predicts that as many as 100,000 students are now studying Mandarin in public and private schools throughout the US. She said the US government has designated (指定) Mandarin as an "important needs" language and provides professional development programs for teachers. "Our government wants to increase our language ability for national security and economic competitiveness," Abbott added.

    At the same time, the Chinese government is spreading knowledge of the Chinese language and culture through Confucius Institutes set up in many US states. For example, the Confucius Institute at the University of Texas in Dallas has been the home of a Confucius Institute for 10 years. It sponsors Confucius Classrooms at 21 local public and private schools, where tens of thousands of students are learning Mandarin.

    Feeding a crowd of hundreds doesn't make Kenny Seals-Nutt nervous.

    In fact, he loves being in the kitchen.

    By the time Kenny, 16, reached his third year of high school in Charlotte, US, he had become vice president of his school's cooking club.

    Kenny said he developed his love of cooking by watching his grandmother, who owned a business.

    And at the age of 5, he cooked his first dish. Taking it to school for lunch, he warmed it up in the school's microwave, while the other kids ate their sandwiches.

    "I love to eat, and it started to become more fun to cook than to have food prepared for me," he said.

    Cooking came easy to Kenny, and he enjoyed adding new ingredients (原料) into common dishes. "It started with a passion (热情) and I wanted to know more," he said.

    Last summer, Kenny put his skills to the test by working with his grandmother to cater his uncle's wedding. Kenny added new changes to the traditional (传统的) dishes that his grandma had prepared.

    Chef Frederick Mookie Hicks, owner of a catering business, said Kenny's success comes from his ability (能力) to multitask (多任务) in the kitchen.

    "He's so enthusiastic (热情的) about cooking that he doesn't let anything stop him," Hicks said.

    You may have heard that humans only use ten percent of their brain, and that if you could unlock the rest of your brainpower, you could do so much more. You could become a super genius, or acquire psychic powers like mind reading.

    This "ten-percent myth" has inspired many references in the cultural imagination. In the 2014 movie Lucy, for example, a woman develops godlike powers thanks to drugs that release the previously inaccessible 90 percent of her brain.

    Contrary to the ten-percent myth, however, scientists have shown that humans use their entire brain throughout each day.

    Over the years, brain scientists have shown that different parts of the brain are responsible for specific functions, whether it's recognizing colors or problem solving. Contrary to the ten-percent myth, scientists have proven that every part of the brain is integral for our daily functioning.

    Research has yet to find a brain area that is completely inactive. Even studies that measure activity at the level of single neurons(神经元) have not revealed any inactive areas of the brain.

    Many brain imaging studies that measure brain activity when a person is doing a specific task show how different parts of the brain work together. For example, while you are reading this text on your smartphone, some parts of your brain, including those responsible for vision and reading comprehension, will be more active.

    A more direct counter to the ten-percent myth lies in individuals who have suffered brain damage – like through a stroke(中风)– and what they can no longer do, or do as well, as a result of that damage. If the ten percent myth is true, then damage too many parts of our brain shouldn't affect your daily functioning. Studies have shown that damaging a very small part of the brain may have devastating consequences.

    If someone experiences damage to Broca's area(布罗卡氏区), for example, they can understand language but can't speak fluently.

    In one highly publicized case, a woman in Florida permanently lost her" capacity for thoughts, perceptions, memories, and emotions that are the very essence of being human" when a lack of oxygen destroyed half of her brain.

    I can't remember the first time one of my children told me, "I hate you." I can, however, tell you that it still happens occasionally, but it doesn't bother me. As their father, I often say things that are unpopular. If they hate me once in a while, I know I'm doing a good job.

    There are three other words that I won't allow in my house, however. Last week, I was watching my older son play with a paper airplane. After he accidentally threw it into a wall and it came apart, his eyes welled up with tears.

    "I hate myself," he said. It wasn't the first time he'd said it, and I was concerned that he'd started to actually believe it.

    I knelt down next to him and made him look into my eyes. I told him that I never wanted to hear those words again, and that he needed to respect himself.

    The difference between your kid telling you they hate you and them saying they hate themselves is that, five minutes later, they've already forgotten they "hate you". Self-hate is much more potentially poisonous and for young people, it can linger into the rest of their life.

    Kids who start to believe they hate themselves sometimes struggle to form new friendships. As teenagers, they avoid the chance to connect with a potential love interest, because they assume they'll be rejected. And as adults, they might choose not to apply for the dream job because they assume it won't work out.

    I know this is true, because I didn't have a high opinion of myself as a child. I found myself struggling in many areas, and I'd hate to see my children suffer the same fate.

    Sometimes, words are just words. But some words can make the kind of impact I'd very much like to avoid for my children. I don't fear strong language; I fear language that makes us weak.
