Today some students get together to talk about the future.1 will the future be like? The students make 2 about it. Listen to them: 3 New York City keeps going the way it is, it will be more crowded and4 , with worse air and more litter(垃圾). We need to learn to5the environment, and then we will have a good place to 6 in. People in New York need to love their city.

    I think the future will be7. When your house is 8, you just need to call your 9 to help you do the housework. 10 will be different: all the classrooms will have computers, and you11 have to take your schoolbags. When you want to12, a flying board(板) will take you anywhere. 13 will fly very fast, and it will only take you an hour to 14 to China from the US. —Dorian, aged 8.

    I think if we walk or ride bikes more, there will be 15 pollution in the world in the future. Then we will live in a better environment.

    Do you know the astronaut Chen Dong? He and another astronaut Jing Haipeng stayed in space for more than 30 days from October to November in 2016. During the days, they, did some experiments in space. For example, they tried to plant vegetables there.

    Chen Dong was born in Henan Province in 1978. When he was a child, he wasn't a good student. When he was in Grade 3, he made the vegetables at school dirty for fun. The vegetables were a gift to the teachers from the school, He was very afraid after that. However, his teacher wasn't angry with him. "You have to think about others when you do such things," the teacher only said.

    After that, Chen became a good student. He later became the class monitor, In 1997, he joined the PLA Air Force(中国人民解放军空军). With a safe flight record of 1,500 hours as a pilot, Chen became a member of the Shenzhou-11 mission(任务) in June, 2016.

    Before flying to space, Chen told his twin sons, "Dad is going out. When you look up at the sky and see a shining star, I am probably there, and say hi to me."

    One American university uses a robot as a teacher to help students with their problems. And none of the students knew that was a robot at the beginning!

    Jill Watson, a robot made in that university, helps the students a lot. When answering their questions, Jill seems to be an excellent teacher. She can give wonderful answers quickly. She sounds natural and usually says good words.

    When someone told the students that their "teacher" was a robot, they all got very surprised.

    "How was it possible? I was talking to a robot?" said Bailey, "She sounds like a common teacher." Another student Jennifer told the newspaper, "We are thinking about choosing Jill Watson to be our best teacher. She is really helpful,"

    Now many students like to ask questions on their school's website. It usually takes teachers too much time to answer them. So the university had such an idea of making Jill Watson. It's a faster way to help the students with their problems.

    Jill can quickly find possible answers in her own computer to the questions and make sure they are all right. After that, she tells the students in an electronic voice that sounds like a famous actress.
