The seasons in Australia are not like ours. When it is winter in china, it is summer there. June, July and August are the winter months; September, October and November are spring, the summer is in January, February and December, and March, April and May are the autumn months.

    A very large part of this country has no rain at all. The east coast (海岸地区) has rain all year, and there are no dry months there. The southeast winds blows (吹) here all the year. They bring rain from the sea. There is not much rain on the west side. The southeastern part of Australia has summer rain from the southeast winds. They only blow here in summer.

    The southwestern part of Australia has winter rain. The west winds blow over the southwest in winter only. In the north of Australia, there is no rain in winter. The rain comes in summer. The northwest winds bring it.

    Once upon a time, a cat and a mouse were good friends. They lived a happy life in the same house. One day they went to the market and bought a big piece of cheese. They put it under a tree for winter.

    A few days later, the mouse wanted to eat the cheese. He told the cat that he had to join a baby's birthday party and then left. The mouse ate half of the cheese and returned home. When the cat asked him what the baby's name was, the mouse said" Half­gone".

    After a few days, the mouse wanted to eat some cheese again. He told the cat he had to join another baby's birthday party. He finished the other half and told the cat the baby was called "All­gone".

    When winter came, the cat went to the tree to get the cheese. But he found nothing. From then on, mice and cats were not friends any more.

    The Internet is shaping our lives. We already have online shopping services and mobile payment. However, this is just a start. The world's leading tech companies are planning to build smarter online communities. {#blank#}1{#/blank#} It was held in Wuzhen, Zhejiang last year. The development of artificial intelligence(AI,人工智能) was a hot topic at the conference(会议). If a machine can learn and solve problems as humans do, it can be called AI.

    The company Alibaba uses AI technology in its unmanned supermarket in Wuzhen. There is no salesperson in the supermarket, just an iPad on a desk that says "please smile". {#blank#}2{#/blank#} The bigger you smile, the more discounts(折扣) you get. Payment is done automatically through your Alipay account. When you first enter the supermarket, the supermarket's AI recognizes(辨认) your face and your account.

    There is also AI that can read lips. {#blank#}3{#/blank#} It recognizes your mouth's movements and turns them into voice or text messages. This could be very useful when you are trying to talk to someone on your phone in a noisy place. Police could also use the technology to help them find criminals by lip-reading recordings from video cameras.

    {#blank#}4{#/blank#} Microsoft's chatting robot XiaoIce can not only provide useful information, but also talk with people like a real friend. XiaoIce has a WeChat account(账户). After following the account, users can start talking with her. {#blank#}5{#/blank#} She keeps improving herself by talking with users.

    These technologies are being put into wider use. We may see a smarter world and better lives in the near future.

    Tom and Tim are twins(双胞胎) .They're four years old. It's difficult for people to tell who is Tom and who is Tim. {#blank#}1{#/blank#} The two boys like to jump, draw pictures and play ball games. {#blank#}2{#/blank#}. But they don't like to take a shower.

    Today, Tom and Tim come back from outside. {#blank#}3{#/blank#} After twenty minutes, Tom goes out. {#blank#}4{#/blank#}Their mother takes Tim into the bathroom. But the boy doesn't want to go in.

    "No ! No! Mom, I'm Tom. {#blank#}5{#/blank#}" "Shut up(闭嘴) ! I know you are Tim."

    At that time, the boy out of the bathroom(洗澡间) is so happy, because he doesn't need to take a shower today.

How do you study every day? You may answer it in one second: have classes at school, take notes and do homework. Feeling a little bored? There are other ways that can make learning interesting and varied(多样化). It's called digital learning. 

Digital learning is a way to help students learn by using the Internet. There are three main kinds of digital learning. Apps are software applications(应用). People can download them on their mobiles. The other two are social networking services, including Weibo and WeChat, and websites. Each one of them is like your teacher. They help you master what you learn at school. 

Compared with traditional learning ways, digital learning has its advantages. Digital learning is varied. It covers almost every school subject. More importantly, it always offers students the newest resources(资源) to learn from. 

Digital learning is also personalized. You can choose what you like to learn. If you don't master what you have learned at school, you can learn again through digital ways. 

However, digital learning also has disadvantages. When you use digital ways to learn, you've got little chance of talking with teachers and classmates. As digital learning uses computers or smartphones, watching the screen too long may be bad for your eyes. It is better to take a rest every 20 minutes.
