"Hello，everyone！Welcome to Tiangong Class."A special lecture（講座）began on Tiangong space station about 400 kilometers above Earth on Dec.9，2021.Lasting for about an hour，the space lecture was given to millions of students.Three astronauts，Zhai Zhigang，Wang Yaping and Ye Guangfu showed how they live and work on the space station and did some interesting experiments.This space lecture was greatly different from the one 8 years before.The"classroom"was bigger.It was China's first extraterrestrial（地球外的）lecture series.
Plants in space — The lab of the space station has many conditions that the Earth lab does not have，such as the weightless environment.The important jobs for astronauts included cell（細(xì)胞） observation and"feeding"plant life.In the lecture，Ye showed experiments about cell growth in a weightless environment.As early as 2016，Chinese scientists tried to grow rice on the Tiangong II space lab to study how plants grow without an Earth-like environment.
Use it or lose it — The human body grows with the pull of Earth's gravity（重力）.But in space，our bones and muscles（肌肉）don't need to support our body's weight.This will cause bone and muscle loss.Astronauts can lose up to 20 percent of their muscles after a couple of weeks.That is dangerous for astronauts because they will be too weak to work.
Astronauts have different ways to present this.Zhai introduced a special uniform called"penguin suit".Wearing it，astronauts use their muscles to stretch the bands in it.This keeps their muscles strong.Wang also showed students how she walked on a machine，and rode a bicycle.Astronauts exercise like that every day to prevent muscle loss.
Young voices — Students were really interested in the lecture.A 13-year-old boy from Tian? jin said，"The most exciting thing I learned is that astronauts"fly"all the time because there is no gravity. "
Yin Peixin，an 11-year-old girl from Hubei said，"My favorite experiment is the one with the table tennis ball.Wang put the ball into a glass of water，but the ball didn't float（漂浮）.This was so magical！"
Look！It was an eye-opening experience that would light up students' interest in science，wasn't it？

1．During the two sessions（兩會），Lei Jun，who started China's tech company Xiaomi，called for more e-waste（電子垃圾） recycling plans in China.
"China should make plans to make full use of those unwanted phones and computers.It can reduce the country's carbon emissions（碳排放）， "Lei told CCTV News.
According to a 2020 UN report，the world's e-waste will reach 74.7 million tons by 2030.That means it will increase by 100% in 16 years.This makes e-waste the world's fastest-growing domestic（家用的）waste.
The report found that only 17.4% of the world's e-waste was collected and recycled in 2019.This means that gold，silver and other high-value materials were mostly burned or thrown away instead of being reused.It's a waste of 57 billion dollars.E-waste can also be bad for the environment and people's health.For example，one phone battery can pollute 600，000 liters of water.
China is now the world's largest producer of e-waste，followed by the US，India and Japan，according to the UN report.However，tech companies are looking for different ways to solve the problem.For example，US company Apple built a robot called Daisy.It can take 200 iPhones apart within an hour and took the useful materials out.With Daisy，valuable materials can be pulled out more easily.
Xiaomi is also setting up e-waste recycling platforms，where people can give away or sell their old electronics.
