A group of boys were playing basketball in the park. The playground was great, there was no fence(栅栏) around it. If one boy missed the ball, someone had to catch it at once, so it wouldn't go too far away.

    One boy threw the ball too hard and it flew like a rocket over the (head) of all the other boys, and kept on flying. Anna was sitting nearby and watching the ducks swim in the river. Suddenly, she (hear) some shouting and turned to see a big, orange object coming towards (she). "Stop the ball," one of them shouted. The ball landed close to the river. The ducks flew away quickly. Anna opened her arms, just in time (stop) the ball as it was going to fall into the river. "Could you please bring it over here?" asked one boy (polite). Anna walked to them with the ball. She was nervous because the boys were (old) than her. However, they were very nice and thanked her saving the ball.

    "Can I join you?" Anna asked. The boys agreed, but they were not sure she could throw the ball even close to the basket. Anna took the ball and then had try. The boys watched in surprise as the ball went straight into the basket. Anna smiled as the boys cheered loudly for her.

    China Post issued(发行) a set of special zodiac(生肖) stamps in honor of 2019 Chinese Lunar New Year, or the Year of the Pig. Famous Chinese 1 Han Meilin designed(设计) the set of stamps2 is most known for his Fuwa dolls made for the 2008 Summer Olympics in Beijing.

    If you, like me, were born in the Year of the Pig. then you are 3, thoughtful and loyal(忠诚的). The Year of the Pig is filled with good wealth.

    Now, let's 4 a closer look at this interesting animal. Pigs were first kept by man about 9, 000 years ago, and are still a very common5 animal in many parts of the world. We don't just use pigs for their meat—almost every part of the animal is used. The hair is used for artists' brushes. The fat is used 6 floor wax(蜡), rubber(橡胶) and plastics.

    Pigs have also been important in the world of entertainment. In 1995 the film Babe starred(使主演)a loveable talking pig as its main character. The film 7 an Oscar Award. In England you can even go to watch pig racing. A farmer, Rob Shepherd, has been raising money 8 charity by holding pig races an his farm, 9 seems that people don't just want to eat pigs!

    Pigs also play an important role in the English language. For example, if someone say that he 10 to the sun one day, you can say "Pies might fly!" to him. Hungry? Well then, you can say "pig out" and eat lots of food.

    5G networks have been considered as one big thing for this century. They allow people to get faster services. Downloading information takes only seconds, instead of minutes.

    But no true 5G phones are able to be used now. It won't work with 5G until such services are built. Users will need an adapter to bring in 5G signals. There's completely no need for users to worry about the safety of 5G signals.

    Where will we probably see 5G first? The answer is in our living rooms. The speeds, about 20 times faster than the standard home Internet connection, are very likely to do wonders in our living rooms. Many users are tired of spending $100 or more monthly in booking cable(有线的) TV. They no more choose cable TV and begin to use streaming(在线播放) services connected to their broadband(宽带) service instead.

    Besides faster access, connectivity might get a little cheaper in future for users only if a complete 5G network is set up. However, the cost of programs and apps will go up. Meanwhile, users are in great need of ordering more monthly services. Comparatively speaking, users are likely to pay more for 5G services.

So far now, it's mainly used at home.…

— Usually, I read for a while in the morning and then went to meet friends or did other things I like.

    If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" of your mobile network. But these symbols will become things of the past after 5G fully arrives.

    On March 30^th, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.

    Now, 4G takes about 100 to 200 milliseconds（毫秒）to send and receive data（数据）. But 5G will get it down to 1 millisecond or less. This big change will not only make our mobile Internet faster. It can be used in many other ways as well.

    For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem-lag. When the car "sees" an obstacle（障碍物）, it sends this information to a data center and receives instructions. However, it takes time to send and receive this information. With this kind of lag，the cars might crash（撞击）because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer, according to CNN.

    5G could also be used to power the Internet of Things（IOT）. This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your refrigerator could automatically（自动地）place an order online for eggs when it finds that there are no eggs left inside.

    All in all, 5G will shape every type of technology that it touches. And you won't have to wait too long for that to happen.

    I loved everything about school except for one person: Mildred.

    Every day, as we walked home after school, she would step on the backs of my shoes. Then, when I stopped to put my shoes on, Mildred would hit me on the back quickly and run away. She scared（惊吓）me.

    Soon, my mother found something was wrong. I told her the whole story. My mum told me not to worry and said she had a plan.

    The next morning, my mum walked up the hill with me. Just as we got to the top of the hill, we saw Mildred.

    "Hello, Mildred," my mum said quietly. Mildred stopped, standing still. Her hands and face were bright red．Her oversized coat hung open. There were only two buttons（纽扣）on it.

    My mother didn't say anything at first. Instead, she buttoned up Mildred's coat and turned the collar（衣领）up around her neck.

    "I'm Amy's mother. I need your help, Mildred." My mother's hands held Mildred's as she spoke." Amy doesn't have any brothers or sisters. She needs a good friend at school, someone to walk up the hill with her after classes are over. Would you be Amy's friend, Mildred?"

    Mildred chewed（咬住）on her bottom lip（嘴唇）and nodded." Oh, thank you!" my mother said." I just know you are someone I can depend on." Then she hugged us and left as though nothing unusual had happened.

    Mildred and I walked on to school. As I looked over at her, I saw that Mildred was smiling! I'd never seen her smile before.

    We walked up the hill each day after school together and pretty soon we became good friends.

    I didn't understand my mum's plan at that time. But finally, I came to understand her message: Love never fails.
