Hello, my name is Kate. I have studied in a nursing school for three years. During my second month of the school, our teacher gave us a small test. I answered the questions very quickly until I read the last one:“What is the first name of the woman who cleans the school?” I thought this was some kind of joke. I had seen the cleaning woman a few times. She was tall, dark-haired and in her 50s, but how could I know her name? I handed in my paper, leaving the last question blank. Before class ended, one student asked if the last question would count toward our grade. “Of course,” said the teacher, “As a nurse, you will meet many people. You should care all of them, even if al1 you do is just to smile and say ‘hello’.”  I've never forgotten that lesson. Later I learned her name was Dorothy.

    In recent years, a number of Chinese technological innovation(科技创新) have been making waves around the world. Among them, four stand out. They are known as "four new great inventions" of modern China. They have made our daily lives more convenient

High-speed trains

    China created its first high-speed railway line in 2008. Since then, the number of passenger trips has grown by over 30 percent every year. By 2016, more than 5 billion trips had been taken China's bullet trains(高铁), according to Xinhua News Agency.

    China is currently working on the next-generation bullet trains that will have a top speed of 400kilometers per hour. By 2020, one-fifth of the country's 150,000-km railway network will be used by high-speed trains. This network will link more than 80percent of major cities across China, said Xinhua.

Mobile payment

    Mobile payment is turning China into a "cashless society" led by third-party payment companies like Alipay. For example, instead of paying y cash, customers now pay for goods simply by typing a short password into Alipay app on their mobile devices.

    Users can also pay their bills through Alipay, such as their water and electricity bills. Alipay also supports cross-border(跨境的)online and in-store payment, which allows users to buy things on international websites and apps.

Shared bikes

    Shared bike services started in Western countries. But China has surprised the world with how quickly it has adopted dockless(无桩的)shared bikes.

    Unlike traditional bike-sharing method, dockless bikes allow users to simply pick up or park a bike on the street through GPS and smartphone To unlock a bike, you just need to scan a QR code on a shared bike with a smartphone app     After you finish riding, you can park it at available parking areas, lock it and pay for ride through mobile payment services.

Online shopping

    With around 751 million internet users, China has long been the world's largest and fastest-growing online shopping market.

    Online shopping now accounts for 15.5 percent of total retail sales in China, according to Xinhua. Thanks to lower costs and fewer licensing requirements(执照要求),it's easier for sellers to open an online shop in China than a brick-and-mortar shop(实体店)。

    It also helped to create jobs of rural areas. In 2016, online shopping created more than 20 million jobs in rural areas, with over 8.1 million running their own online shops, said Xinhua.

    Aron Ralston is an American man who is interested in mountain climbing. As a mountain climber, Aron is used to taking risks. This is one of the exciting things about doing dangerous sports. There were many times when Aron almost lost his life because of accidents. On April 26, 2003, he found himself in a very dangerous situation when climbing in Utah.

    On that day, Aron's arm was caught under a 360-kilo rock when he was climbing by himself in the mountains. Because he could not free his arm, he stayed there for five days and hoped that someone would find him. But when his water ran out, he knew that he would have to do something to save his own life. He was not ready to die that day. So he used his knife to cut off half his right arm. Then, with his left arm, he bandaged himself so that he would not lose too much blood. After that, he climbed down the mountain to find help.

    After losing his arm, he wrote a book called Between a Rock and a Hard Place. This means being in a difficult situation that you cannot seem to get out of. In this book, Aron tells of the importance of making good decisions, and of being in control of one's life. His love for mountain climbing is so great that he kept on climbing mountains even after this experience.

    Do we have the same spirit as Aron? Let's think about it before we find ourselves "between a rock and a hard place" and before we have to make a decision that could mean lire or death.

    At school：

    When students around you begin to push, try to hold onto something, or stay in a safer corner. {#blank#}2{#/blank#}

    On your way home or to school：

    Wait for the green traffic light. {#blank#}3{#/blank#} Wear clothes in bright colors, so the drivers can see you easily.

    {#blank#}4{#/blank#}：

    Stay calm and leave quickly. To keep clear of smoke (烟雾),use a piece of wet cloth to cover your mouth and nose.

    For riding on the escalator（自动扶梯）：

    {#blank#}5{#/blank#} You should hold onto handrails（扶手） and stand on the right side of the escalator, because right arms are stronger.

    Young children don't have the skills or knowledge to stay safe in heavy traffic. The following tips (忠告) will be helpful for you to keep your children safe in heavy traffic. Children learn about road safety by watching others. As parents, make sure that you always set good examples. Your children will follow you and think it's OK to do like you. Teach your children to pay attention to traffic lights when you cross the road together with them. This helps them understand when it's safe to cross. Make sure that you walk between your children and traffic, and hold their hands all the time.

    When your children are a little older, you can start to tell them the importance of traffic knowledge. Let them start to understand the reasons why they need to be so careful. Talk with them about road signs and traffic rules.

    Ask your children to play in a safe place. Never let them ride bikes on the road without an adult present at rush hours.

    The most important thing you can do is to keep your children from getting hurt, so parents encourage them to follow traffic rules. After knowing about traffic rules, they'll volunteer to obey them. In this way, they'll be careful enough to keep themselves away from danger.
