On Dec. 9, 2021, three Chinese astronauts gave a science lecture 400 kilometers above Earth. Zhai Zhigang, Wang Yaping and Ye Guangfu, who are working abroad the Tiangong space station, showed millions of students their life there. They also did some fun science experiments. Let’s take a look at some of them.
Use it or lose it
The human body grows with the pull of Earth’s gravity. But in space, our bones and muscles don’t need to sustain our body’s weight. This will cause bone and muscle loss. NASA says that astronauts can lose up to 20 percent of their muscles after just a couple of weeks. That is dangerous because they will be too weak to work.
Astronauts have different ways to prevent this. During the lecture, Zhai introduced a special uniform Ye was wearing. It’s called a “penguin suit”. There are many elastic bands inside the suit. Wearing it, astronauts use their muscles to stretch the bands. This keeps their muscles strong.

During another experiment, Wang made a water film. Then she added more water drops onto the film to make it a water ball. This can never happen on Earth. Why?
We need to first understand the surface tension of water. It is like a “skin” of water. The “skin” is there because water molecules are drawn to each other. Most of the time, gravity is too strong and it breaks the “skin”. But with zero gravity in space, the “skin” stays strong and the water ball will not break.
Water in space acts differently from water on Earth in other ways. For example, water will not flow downward if you try to pour it into a cup. That’s why astronauts usually drink water through straws in sealed bags.

Fathers who value (重视) education have children who do better in school than those children whose fathers don’t value education. What’s more, fathers who spend quality time with their children may give their children happy memories which may last a lifetime.
While each father is a unique person who educates children in his own style, good fathers have something in common.
Good fathers attend their children’s school activities. They also involve the children in their lives and the adult world by taking them to see the workplace, or by taking them when the car needs to be repaired, etc.
Good fathers expect a great deal from their children, but also accept and support the unique individuals (个体) that their children are becoming.
Good fathers prefer explanations and reasoning to force.
Good fathers know their time with children is really an investment (投资) in them.
Being an involved father is good for children and good for fathers. Both children and fathers have the chance for growth and development. Today’s lifestyles are changing. More and more fathers are keeping a balance between their personal life, work, and family time.

Learning in the Field
A fun farming class took place in the fields! On Sept 15, Grade 7 students from Jinan No.34 Middle School, Shandong, went on a field trip. They learned about farming, reported Qilu News. At the grain base (粮食基地), teachers talked about grains with students and answered their questions. The students saw millet and soybeans (小米和大豆). They touched the wheat (小麦) and learned that people usually harvest (收获) the wheat at the end of September.
Young Reporters Put on a Show at School
Students at Johnson Middle School in US, are reporting their school’s news in their own news program. The students take turns to make the program. They set up a green screen, sit down and give their classmates the headlines (新闻提要) of the day. They include (包括) what’s going on in the school and news about future events. They share the lunch menu of the day. “The kids come in excitement. They love being on the news and sharing the news with other kids. They are eager (渴望) to know what’s happening around them.” said B.J. Burke, the school teacher.

On Nov 8, students from Nanjing Foreign Language School have a special class. During the class, they have a hands-on experience of making folk clothes. The students took on the challenge (挑战) making their own bags through tie-dyeing (扎染). It is a dyeing skill to make blue calico (印花布). The dye and the cotton material (材料) used to make blue calico all come from nature. “Tie-dyeing is a magical art. Everyone does it a bit differently, and you never know exactly how it will look in the end.” said Ma Qianyu, a grade 8 student, happy with her work. The students will later go to Nanjing Museum to get more knowledge about life in Jiangsu and the folk customs there.

【推荐1】Something happens to many children when they are out of school over the summer months. It is called the “summer slide.” This may sound like a ride at a water park. But it’s not. Summer slide is that the children can’t remember much of what they learned during the latest school year. To fight against the effects（影响）of summer slide, some parents send children to camp or find other activities to keep them learning. As the new school year begins, most children are soon very busy with new classes and school-related activities. However, experts say keeping children busy all the time is not good for them.
What should parents do instead? Nothing.
Lea Waters is a psychologist, who has been working on helping children succeed for over 20 years. Waters says slowing down actually helps children become the best they can be. “It’s a little bit like, if you have too many programs running on your computer, your computer starts to slow down. And when you close down those programs, your computer runs faster. It’s very much like that for a child’s brain.” Machines need to be reset, while kids need to goof off. “What I mean by goofing off is really allowing kids to have some downtime. They don’t need to do a specific task. They can do something that they choose to do like shooting baskets, or doing a creative project, cooking. It’s a project they’re interested in doing that they can do.”
She adds that goofing off does not mean the brain isn’t working. “It uses that time to make a kind of decision about what information I should keep and put into my memory, what information I do not need and I give up. It’s also an important network for helping us to remember better, to develop emotional intelligence（情商）and a sense of identity…”
Lea Waters says she hopes parents will accept the fact that children don’t have to be busy all the time. Children and adults need time to goof off now and then.

Do you know that there’s a possibility that you may live forever? You will have computers which are 1,000 times more intelligent than Albert Einstein, one of the smartest scientists ever in the world? Yes! All these may happen in 20 years or more. In the next 20 or 30 years, the world will change much faster than ever before because the technology change will be simply breath-taking.
Computers will acquire human personalities, as well as the ability to understand words and their meanings when you speak to them. Tomorrow’s computer will be so developed that it can have a face-to-face chat with you like an old friend. In fact, you don’t even have to speak to it. Just like a friend, the computer will also have the ability to understand your thoughts.
However, will computers take over the world? Probably not, for people will also acquire-superhuman abilities. They may never die. “Unless a person is unlucky enough to die early from an accident or a disease, he has a good chance of not dying at all. Genetics will make this possible.” says Pearson, a British futurologist as well as a trained physicist.
Recently there have been many reports about discovering the code of the human genome, which determines many aspects of heredity. This finding will make it possible to repair damage caused by age and disease, keeping people young forever. Besides, if people suddenly die, it would be possible to recreate them with the help of the genetics.
So we have the reason to believe, with the development of genetic engineering and computer science technology, human beings will have superhuman abilities and the possibility of being young and alive forever. While at the same time, computers will be much more intelligent than we can imagine. Then who will control the world?

Builders made special islands in the river to provide supports for the bridge. There is also a 6.7-kilometer underwater tunnel in the middle of the bridge. This is for ships to sail over. The new bridge is longer than 14 Golden Gate Bridges. The bridge will cut the time it takes to travel from mainland China to Hong Kong and Macau. The journey time to Macau has been cut from three hours to just 30 minutes by bus.
Chinese president attended the opening ceremony (开幕式) on Thursday. He hopes the bridge will connect 68 million people in 11 cities. Up to 29,000 cars will cross the sea link daily by 2030. A trade and tourism expert said, “This makes Hong Kong a lot more accessible for goods, passengers and trade.” Tourists will be able to drive across the bridge, but local car owners will have to buy a special permit. Most drivers will take a bus to make the journey.

【推荐3】China launched its Wentian space laboratory on Sunday, July 24, 2022,sending the country’s largest-ever spacecraft to Earth’s orbit to become part of the Tiangong space station.
Appearance
Wentian laboratory module (问天实验舱) has three parts: working cabin, airlock cabin and service module. With a length of 17.9 meters and a takeoff weight of 23 tonnes, the diameter is 4.2m. The height is almost like a six-story building and the weight of ten cars.
External working equipment
The lab will carry a set of 5-meter-long auxiliary robotic arms (辅助机械臂) outside the airlock, they are small but precise, making it easy for small and medium-sized devices to be caught for more delicate operations.
The “small arms” can also be connected with the core module’s “big arm” to form a 15 meters long composite arm (组合臂) for more work outside the module. By then, the arm will climb between the three modules of Tianhe. Tianwen and Mengtian, and the “mech warrior” (机甲战士) can control an even greater area.
Energy supply
Working together, the two giant solar panels (太阳能板) will collect more solar energy, generating electricity of more than 430 kwh on average per day, which can provide enough energy for space station operations.
Noise treatment
There are three sleeping areas and one sanitation area (卫生区). The module has got many equipments (设备). To provide a quiet environment, the engineers found out the nosiest equipment and they used stricter noise control methods. Different types of the noise, we can take different methods to control. For example, the noise caused by acoustic radiation (声辐射) are placed in the boxes. As a result, the noise level in the working area can be kept between 10-60 decibels (分贝), 10 being the lowest setting for the sleeping area, allowing the astronauts to sleep quietly.
Outside the module, cameras are set up to record Earth and outer space. Ground controller will see the site situation and provide real-time protection.
