Mr. Smith is our Chinese teacher. He always asks the same student to answer his questions because he doesn't look at the students at all. Yesterday he questioned Dick three times. Dick was very angry. After class Dick asked me, "What shall I do?" I told (告诉) him a good idea. Now we are having a Chinese class. Mr Smith wants one of us to read the text. "Dick, please read the text." "Dick isn't here today." Dick stands up and says. "Oh, I see, you read it, please."

    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."

I'm Bob. I work at night from Monday to Thursday. So in the daytime (白天), I often sleep for at least 7 hours. Then I get up, have some food and watch TV. I usually watch TV for more than two hours every day. At 7:00 p.m., I go to work by bike.

But on weekends, my life is different. I usually sleep at night and do different activities in the daytime. For example, last weekend was quite full for me. On Saturday morning, I went to learn dance. I have dance lessons once a week. In the afternoon, I went to play basketball with my friends. We played for three hours and felt excited. I thought it was good for my health. On Sunday morning, I drove to the dentist for teeth cleaning. In the afternoon, I went to the movies with my friend, Tom. I thought the movie was interesting, but Tom thought it was difficult to understand (理解).

Ding Chen, a teenager from Anhui Taihe No. 3 Middle School, invented (发明)a machine for the old to climb the stairs. And he1 the International Youth Gold Medal for his invention.

The Ding family lived in an old building,2 they had to climb stairs every day. His grandpa had difficulty climbing up the 3 . It became even 4 after he fell ill. When Ding Chen was a five-grader, he wanted to invent something for his grandpa to go up the stairs more5 .

Three years later, 13-year-old Ding 6 this problem. He invented a booster (助力器). People just need to set it on the stair railing (扶手) and hold it. Then it will pull people to go up. Ding's middle school teacher Zhang Gang helped him make his idea real.7 worked for about half a year to design the booster.

8 , Ding will try to make his invention perfect. If possible, he wants to find companies to9 it in the factories.

"I hope my invention can help all the people in 10 ," he said.

A group of American high school students built a bus stop shelter(遮蔽物) for a 5- year- old boy Ryder Killam.

There is something {#blank#}1{#/blank#} with Ryder's legs. Every morning, he has to wait for the school bus outside in his wheelchair(轮椅). {#blank#}2{#/blank#} it's only about 20 meters from his house to the bus stop, it is quite a long way for Ryder.

At first, Ryder's family {#blank#}3{#/blank#} up a big umbrella, so Ryder could sit under it when he waited. But it didn't {#blank#}4{#/blank#} when the weather was bad. They tried {#blank#}5{#/blank#} a few other ways but they hardly ever worked, either. They decided to ask the community for {#blank#}6{#/blank#}.

Some high school {#blank#}7{#/blank#} heard about the news and wanted to give the little boy a hand. They worked for weeks and built a nice shelter for Ryder. It is just like {#blank#}8{#/blank#} small house. Now, Ryder can stay in it when he waits for his school bus without (不用) worrying {#blank#}9{#/blank#} the bad weather.

" We are really happy to work for our community," one of the students said." And {#blank#}10{#/blank#} is pretty cool to help someone in need."
