              We asked thirty young people between 14 and 18 several questions. All the children had computers at home. The average (平均) time spent on a computer in a week was about 12 hours, with the highest about 32 hours, and the lowest only 5 hours. Most children said they usually used computers to play games. Fourteen children told us they did some word-processing (文字处理) at times. Eight people told us they kept addresses and phone numbers on their computers or used them as diaries. Only three people said they were learning to write computer programs and nobodyused databases (数据库). Only two of them said computers helped with their lessons. The diagram (表格) gives all the results one by one.

              The results show that computer use is quite common among 14 to 18-year-old children. They also show quite clearly that computers are seen by most young people as little more than game machines. It means to us that, though computers are common (普遍) in the home of young people, they have not yet become popular in everyday life.

              On the night of the Mid-Autumn Festival in 2016, Tiangong-2, China’s second space lab (空间实验室) flew to the sky. It flies around the Earth and will run for at least two years.

              On October 17th, the Shenzhou 11 manned spacecraft (载人飞船) sent two astronauts to the lab. They worked in the lab for thirty days. They did important experiments(实验) in physics and medicine.

              On November 20th. , the two astronauts appeared in the TV show Challenge(挑战) the impossible. They gave us a wonderful show from the space lab Tiangong-2.They successfully challenged what seemed impossible in space. Before the game, Chen Dong and Jing Haipeng, an astronaut on his third space trip, showed the bat they were given to play pingpong in space. Then the astronaut Chen Dong sent a ball on one side, ran after it to the other side to catch up with it, then beat it back. He did like this many times. According to an expert, playing pingpong in space is really impossible. In space, when the ball is hit, it goes only straight forward and cannot spin(旋转) in the air. But Chen Dong made it. After that, they showed us some young plants of lettuce (a kind of vegetable)and rice that they grow in space. This is the first time the Chinese plant vegetables in space. At last, Chen Dong stood on his head to drink some pu-erh tea. He finished this special challenge successfully.

              After the space lab task comes to an end, China will start building our own space station. The plan is to have the first space station working around 2022.
