I grew up in New Hampshire, a small town in South Canada, where in my father's words for the seasons were “Spring, Summer, Fairtime and Winter!”At that time, a week-long fair was held in the town every autumn. Thousands of people from other towns came to sell and buy things. It was the busiest time of the year.

    When “Fairtime” came, my grandma became the busiest person of the family. Grandma was a kind old lady. She was good at cooking. All her relatives liked the food she cooked. During “Fair time”, they would come to live in her house and have meals there. Grandma was always happy to look after them.

    Year after year, many people moved to big cities. There was no longer “Fairtime”. Grandma became very old and was gradually going blind. My parents and I moved to live with Grandma. We did our best to make her life comfortable. I was at high school then. What I often did at home was to help Grandma with the daily newspaper's crossword puzzle. However, she didn't look happy. She often sat in her room for hours, without saying a word.

    To attract（吸引） people to move back, the Town Hall decided to reopen the fair. One day, when I came back from school, I saw Grandma wearing her glasses, washing the dishes in the kitchen. With a big smile on her face, she looked much younger. She told me that her two nieces(侄女) would come. “They said the food I cooked was very delicious and they wanted to stay in my house again,” Grandma said happily. “They will stay here for one week and we can have a big party. That must be the busiest week I've had in years!”

    I suddenly realized that Grandma didn't want to be looked after. She wanted to be “useful” and helpful.

    Michael Perham (born on 16^th March, 2000 in Hertfordshire, England) is a boy who, at the age of 17, became the youngest person to sail around the world in the 50 feet racing boat, completing his journey on 7^th August, 2017. He started the world trip on the 15^th of November 2016 from Portsmouth, England.

    Just six days after Michael Perham set sail from Portsmouth, he started having serious problems with the boat, which he was unable to fix himself on the sea. He had to stop in Portugal. Just one day later, he set sail once again, with the hope of breaking David Dick's world record for the youngest person to sail around the world.

    Michael met many challenges along the way, including rough seas and knock-downs in the Southern Ocean, terrible loneliness and fighting storms, but the largest difficulty Michael faced was the boat itself. It caused one problem after another. He celebrated his birthday in March last year among the dolphins in Indian Ocean.

    Michael Perham has entered the record books after becoming the youngest person to sail around the world. The teenager already holds the record for being the youngest people to sail across the Atlantic, aged just 14.

    Michael Perham plans to create the Sail Michael Fund to encourage young people to take to the water. He is also aiming to take part in the 2020 Olympics.

    This is Tom. He is a student. He is in Class Four, Grade Seven. There are 25 girls and 20 boys in his class. His English teacher is Mr. Zheng. He is about 31. He is a good teacher. The students all like him.

    Tom has a good friend. His name is Jim. He is from Canada. He is in Class Four, Grade Seven, too. Tom and Jim live in China now.

    They say that "travel is the best teacher" and there is no better example of this idea than the Ming dynasty travel writer and geographer Xu Xiake (1587-1641). His book The Travel Notes of Xu Xiake, not only encouraged a love of travelling among Chinese people but provided important scientific information about the country's land and geography.

    Born into a wealthy Jiangyin family, Xu became interested in books about different places at anearly age and wanted to travel. When he was 18, however. Xu's father died and so, it seemed, did his travelling dreams. He now was responsible for the family farm and taking care of his 60-year-old mother as tradition required.

    But his mother had different ideas. Understanding her son, slove of travel and valuing the knowledge he could get from such experiences, this modern-thinking woman refused to keep her son at home. She agreed that Xu could travel for three months every year, when there was less farm work.

    So at the age of twenty and with his mother's support, Xu set off for the first time, leaving behind not only his mother but his new wife as well. He would repeat this goodbye each year for most of the next 30 years. During this time, he travelled throughout the Ming kingdom, carefully studying the lands he passed through and recording his experiences and many discoveries in a diary. This diary, which once had over 500,000 words, would eventually become The Travel Notes of Xu Xiake.

    Although rich, Xu avoided comfortable travel, preferring to go almost everywhere on foot. This way he could research the environment in detail and get a true picture of the natural world. Many of his trips were to hard-to-reach mountain areas, and through wild forests where few people lived. His willingness to face hardships came at a cost however. Progress was slow and tiring and he was frequently sick, robbed and beaten during his journeys

    Sadly Xu became seriously ill during his last and longest journey, a 4-year trip through the Southwest of China. He died in 1641, soon after returning to his hometown for the last time. When his diary was finally printed years after his death, much of it had been destroyed or lost. Although incomplete, it still made Xu a travelling legend around the world.
