    Most people have map apps on their phones that can show their locations and guide them to where they want to go. But how do these app systems know your 1 at any time or place? They find you by using satellite navigation (satnav) systems (卫星导航系统).

    A satnav system uses groups of satellites to find the users locations. This location information is then sent to a 2, such as a smart phone.

    The first satnav system is the Global Positioning System (GPS) (全球定位系统), which belongs to the United States. The system is the world's 3 satnav system. But China's satellites are important 4 improving the satnav system. Beidou, has overtake (超过) GPS in size, Japan's Nikkei Asian Review reported.

China5 Beidou's first navigation satellite into space in 2000. China also became the  6 country to build a satnav system after the United States and Russia, People's Daily reported. Over 30 7 in Africa and the Middle East are 8 Beidou system right now.

    With its world-leading technology, Beidou is leading Chinese people to a better life9 playing important 10 in different areas, according to Xinhua News.

    For example, over 6.2 million vehicles in China are using Beidou for navigation, according to a report on the Beidou system's construction (建造) and development.

    At the newly-built Beijing Daxing International Airport, Beidou has been used to keep track of (追踪) loading and unloading vehicles 11 and outdoors. When the 12 opens, each baggage cart has Beidou navigation equipment to help passengers get their luggage 13.

    For a satnav system, the 14 of satellites is important for improving the system's positioning accuracy(定位精度). The more satellites, the15 accurate the positioning is. The satellite navigation system is useful in many ways.

    My people, My country, a 158-mintue film celebrating the 70^th anniversary of the founding of the People's Republic of China, is set to hit Chinese theaters on September 30.

    Edward rose early on the New-Year morning. He looked in every room and wished a Happy New Year to his family. Then he ran into the street to repeat that to those he might meet.

When he came back, his father gave him two bright, new silver dollars.

    His face lighted up as he took them. He had wished for a long time to buy some pretty books that he had seen at the bookstore.

    He left the house with a light heart, expecting to buy the books. As he ran down the street, he saw a poor family.

    "I wish you a Happy New Year," said Edward, as he was happily passing on. The man shook his head.

    "You are not from this country?" said Edward. The man again shook his head, for he could not understand or speak Edward's language. But he pointed to his mouth, and to the children shaking with cold, as if to say, "These little ones have had nothing to eat for a long time."

    Edward quickly understood that these poor people were in trouble. He took out his dollars, and gave one to the man and the other to his wife.

    They were excited and said something in their language, which doubtless meant, "We thank you so much that we will remember you all the time."

    When Edward came home, his father asked what books he had bought. He hung his head a moment, but quickly looked up.

    "I have bought no books," said he. "I gave my money to some poor people, who seemed to be very hungry then." He went on, "I think I can wait for my books till next New Year."

    "My dear boy," said his father, "here are some books for you, more as a reward for your goodness of heart than as a New-Year gift."

    "I saw you give the money cheerfully to the poor German family. It was nice for a little boy to do so. Be always ready to help others and every year of your life will be to you a Happy New Year."

    Do you know 5G? It is the fifth generation (代) of mobile network technology. These new networks are coming.

    China just issued commercial licenses (发放商用牌照) for 5G on June 6. This means that China's telecom companies were soon able to offer 5G networks for mobile phone users.

    Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What's special about 5G?

    5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data. But 5G will get it down to 1 millisecond or less—this is almost real-time.

    This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.

    5G+entertainment (娱乐）

    5G networks are about 100 times faster than 4G. This means you can dowload a movie in seconds using 5G.

    Also, virtual reality (VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

    5G+transportation

    5G will also bring us safer self-driving cars. These cars can send signals(信号）to each other. They also talk to traffic lights and road sensors(传感器). 5G will allow cars to react even faster than human drivers.

    5G+smart homes

    5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.

    For example, your toaster can automatically (自动地) start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.

    One evening, Zhang Luyang was working on her math homework. The 12-year-old girl from Sichuan opened the Tik Tok, known as Douyin, to watch some short videos. She just wanted to take a short break, but half an hour later, she was still watching short videos.

    Zhang is one of many teenagers who enjoy watching short videos on apps like Douyin. The videos typically last from 15 seconds to 5 minutes. According to a survey by the Central Committee of the Communist Youth League of China, 20 percent of teenagers watch short videos during whatever free time they have. About 10 percent check short video apps several times a day.

    Sun Zhenyao, a 14-year-old boy from Anhui, says he likes short videos because they are interesting. "It's the perfect thing to do when I want to kill small amounts of time," he said.

    Zhang says she learns a lot by watching short videos. She follows a Chinese vlogger living in the US on Douyin. The vlogger does funny things, like selling pancakes on the street and inviting foreigners to watch The Wandering Earth, she said, "His videos teach me about cultural differences."

    However, Zhang and Sun also say they sometimes waste too much time watching short videos. Apps like Douyin and Kuaishou have features that prevent users from watching videos for too long. Users can use "teen mode", which sets 40 minutes a day for watching short videos. Sun says this has helped him cut down the amount of time he spends watching videos.

    The Adventures of Tom Sawyer is a story full of fun. Tom, the m       character of the book, is a lively and clever boy. He doesn't like people telling him what to do, so he a       gets into trouble. He and his best friend, Huck Finn, run away to an island in the middle of the Mississippi River. Tom has more t      , because a bad man named Injun Joe is looking for him. Later, Tom g       away from a cave successfully with another friend, Bechy. He also finds Injun Joe's treasure box and takes it away.

    My favourite part of the book is when Tom and Huck start their adventures on the island. At first, they are h      . But they feel very sorry when they hear that everyone thinks they are d       , so they come back home. They suddenly appear at their own funeral(葬礼）in the church. Everyone is s       to see them at first, but very pleased to find that they are alive.

    The great book is m       than an adventure story. It d       people's lives in the southern part of America at that time. It tells how young people grow up, how people love each other and how bad people pay for their actions. It is written in e       English, and the dialogues sound especially real. Today, it is still read and loved by people all over the world.
