What is inside Mars(火星)? Perhaps I may give you the answer in the near future. I am InSight(洞察号).I am a spacecraft. On Nov 27,I arrived on Mara. In fact, I am the eighth spacecraft in my family to successfully land on Mars. But I'm the first to study the things inside it.
What do I look like? I have an arm, It is 1.8 metres long. At work, if I need to move the things from my body to the ground, the arm helps me. On my arm, I have my single eye. You are right-it's a camera. I can use it to take pictures of Mars. As for navigation(导航),I will be led to the right place because scientists on the Earth keep telling me about directions. With three legs, I can stand well. And look at my two big “wings". Actually the get lots of power from the sun to make me work.
For the next 24 months-about one Martian year, I will stay on this red planet. Unlike brothers or sisters, I don't move a lot when I'm working on Mars. I will Just stay at one place use my heat probe(探热仪)to explore nearly 5 meters deep inside Mars. This way, I can get a lot of information about the inside without damaging the planet. Then I will send the information back to Earth. This may help scientists find out how Mars started.

【推荐1】What do black holes look like? Human beings have wanted to know about it for a long time. In 2019, we finally got the answer. They look like dark circles with a bright ring around the outside.
Scientists took the world’s first photo of a black hole. Scientists didn’t use a camera to take the picture. They used eight radio telescopes in different places around the world. Telescopes got signals (信号) from the black hole. Scientists used computers to process (处理) the signals. It took them two years to get the final picture.
The black hole is very far from Earth—about 55 million light years away. One light year is the journey that light travels in one year. One light year is about 9 trillion (万亿) kilometers.
This isn’t the only black hole in the universe. In fact, scientists believe every large galaxy (星系) has a big black hole at its center. The one in our galaxy is called Sagittarius A.
Black holes are some of the most mysterious (神秘的) things in the universe. This photo can help us learn more about them.

【推荐2】The idea of life in outer space has been talked about for a long time. Some scientists say that life development on Earth was far too unlikely for it to have happened anywhere else. Things had to be perfect for us to make it on this planet.
Other scientists say that space is too big. Stars and other planets are far too numerous for there to be no other life in the universe.
For many years, there have been reports of visitors from other planets. People all around the world have claimed to see alien spaceships or even aliens themselves.
There have been glimpses of these so-called UFOs (unidentified flying objects) flying through the air and they have even ben captured on video. Some Americans believe that the U.S. Army found an alien spaceship crashed in the desert and then lied to the press about it. Although these sightings may be true, scientists have not found significant evidence that aliens exist.
If you go out into the countryside on a clear night and look up, you can see thousands of stars. Those stars make up a tiny part of our universe. There are more stars, planets, and galaxies than we can count. Even the smartest scientists can’t even come close to defining how big space is. The number of possible stars and planets out there is bigger than our ability to count. If we are really on the only planet that can sustain life, then we are very special in a universe full of amazing things.

【推荐1】With the help of the Internet, robots have become good helpers in the fighting against COVID-19 in Shanghai.
Inside one hospital in Shanghai, the first 28 “disinfection（消毒）robots” have been put into use. Each of them can work for a whole day. At the same time, a group of “5G smart indoor cloud robots” can carry over 20 boxed meals at a time. It took about 20 minutes to carry meals in the past. With the help of these robots, they save much time and finish the work in just 5 minutes.
These robots help to cut down the risk of cross-infection（交叉感染）among sick people. What’s more they help workers get away from danger. It’s reported that more than 200 robots will serve at hospitals. More 5G smart robots are also ready to work. They can get different information to help experts make right decisions.
Outside hospitals, more and more smart robots and unmanned（无人操纵的）cars have been put into use to fight against COVID-19. Meituan has sent more than 10 unmanned cars to Shanghai to cut down the transport（运输） pressure on some neighborhoods in Pudong New Area.

【推荐2】OpenAI has created a new AI called Sora and it is getting a lot of attention. Unlike other AIs that make texts or pictures, Sora can turn sentences into videos! You can enjoy these videos on any screen, big or small. Sora knows how to make scenes with many people doing different things, paying attention to every little detail. It’s also getting better at showing things the way they really look.
Sora learns by watching lots of videos and breaking them down. At first, the videos it makes are gray and look messy. But through keeping learning, Sora improves them until they look good. ChatGPT helps too, by making it easier for Sora to understand what we ask for.
But Sora is still being tested and is not perfect yet. It sometimes has problems with complex (复杂的) actions. For example, there’s a video where a grandma blows out a birthday candle, but the candle’s flame (火焰) doesn’t move. Even though Sora has things to work on, it’s an exciting step forward in AI. It shows us something amazing in the future where AIs can make even more fantastic videos.

【推荐3】Bi Sheng was born in Song Dynasty. He lived in a small village which lies in Huanggang today. He was the world’s first inventor of the printing. It is about 400 years earlier than the printing in Germany.
The printing is also called the movable type printing(活字印刷). But how did it work in the past?
First of all, the clay was made into movable types. Then words were engraved carefully onto the types. After that the words were chosen and put in right order in a box according to the text. Next, the workers brushed ink onto the movable types. Finally the types could be used for printing. They could be used again and again for different books.
The movable type printing plays an important role in Chinese culture. With the help of it, Chinese culture spread around the world more quickly. At the same time, the movable type printing was widely used in the world at that time. As a result, more and more culture communication among countries took place.
The movable type printing, the compass (指南针), gunpowder and the paper—making are called four great inventions of China. They make China own an important and even top position in the history of human civilization(文明).

First， look at why you do it. In other words， what’s the result(结果) of doing this thing? If your bad habit is shouting at people when you are unhappy or under pressure(压力)， what do you get from it?

【推荐1】Being bored is no fun, especially at work. However, a recent study at the Australian National University suggests that boredom may have unexpected advantages.
In a study, 52 people were given a boring task of sorting (分类) red and green beans for 30 minutes, while another group of 49 people was asked to create art projects with paper, beans, and glue. Then both groups were instructed to spend five minutes on a creative task. Surprisingly, the group that had performed the boring task produced much more creative ideas than the group that had taken part in the art project.
“From the research, we can learn boredom is not necessarily terrible,” says the study’s lead researcher, Guihyun Park. “People want to get out of a boring condition, so they will look for novelty (新颖), which can lead to special thinking and bring out creativity.” Moreover, it’s also worth noting that studies have found that not everyone experiences the same level of creative advantage from boredom. Researchers have discovered in one experiment (实验) that people who are open to new experiences are more likely (可能的) to learn a lot from being bored.
For designers (设计师) and anyone in a creative field, boredom is not something to fear, but to gladly accept. J. K. Rowling, the writer of the Harry Potter series (系列), has shared how she would spend hours sitting on trains, letting her mind wander (漫游) and coming up with new ideas for her stories. This boredom allowed her to bring out her creativity and imagination, leading to one of the most beloved book series ever.
