【推荐3】Crew members of Shenzhou XII mission gave a science lecture（讲座）400 kilometers above Earth to millions of students on Thursday afternoon, December 9, 2021 in the Tiangong space station.

The three astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu greeted students, teachers and other viewers when the lecture started in the afternoon. They explained their life and work inside the space station.

The astronauts made scientific experiments to display interesting physical phenomena（现象）in space, for example a “water ball”. They also invited young viewers to do similar experiments along with them to see the differences between space and land environments to experience the fun of exploration. Besides, they answered questions from students during the lecture.

Tens of millions of teachers and students across China, including Hong Kong and Macao watched the hour-long televised event. They were excited to have such a chance to understand more about biology, physics and chemistry through the experiments in space.

The activity showed the nation’s technology development, and our students have learned some new things that we could not teach in a class. It was the first lecture of the Tiangong Class and more lectures will be held. Such activities will help spread knowledge about space and increase the love for science among young people.——Rinchen Drolkar, a teacher

The astronauts’ experiments really surprised me. I would like to take part in our country’s space exploration program in the future——Wang Yihan, from Tibet 5th-grade student

Audience Etiquette During Sports Games

Many people would like to watch sports games. First, you need to know about audience etiquette (观众礼仪) .

Most sports games have rules for the audience written on the back of the tickets. Read your ticket carefully before you arrive. Try to reach your seat half an hour before the start of the event and don’t leave when a game is in progress. When you leave, remember to take away your soft drink bottles and other rubbish.

During exciting games, try to control yourself. Don’t criticize (批评) the performance of players and coaches. Be careful with your words and behavior, since some may cause anger among other people in the audience.

Clapping (鼓掌) is a special form of body language you can use to communicate with players, but you should do it properly. When players first appear, clap your hands together to welcome them, but don’t go on for too long. After an excellent performance, clap warmly. If someone fails, your clapping will help encourage them. Clapping is not welcome, however, when players need to keep their attention.       

Different sports have different rules for the audience. Enjoy gymnastics (体操) silently. But lots of cheers can help basketball and football players. When you watch table tennis games, flash is not allowed. Mobile phones are not allowed in shooting centers.

To behave well, you should spend time learning the game rules and related culture of each event.

Water-splashing Festival（泼水节）It is the biggest festival in Thailand. It's in the middle of April every year. For three days, people sing, dance and splash water on each other.
