1 . On September 2nd, BUAA (北京航空航天大学) welcomed its first 2021 student. His name is Xing Yifan, coming together with his parents ahead of time.
"Yifan is 18 years old, but he weighs only 18 kilograms. When 6 months old, he suffered from LAMA2 (渐冻症), a type of disease that no more than a hundred people have got in the country. However, with his strong will, he made one amazing achievement after another in learning. In this year's college entrance exam, he entered BUAA with a score of 645.
Because of the illness, Yifan can only sit alone for a while, unable to stand and walk like other children. In class, he could only put his head on the table and his eyes can only scan half the pages of the book. He couldn't turn over the book with one hand. And he could only sit and listen to a class for up to 30 minutes, with the remaining 15 minutes to lie down to listen to his teacher.
But these did not scare Yifan, with only a little muscle strength left in his hands, he finished one test paper after another, more than 20 a day, often till one or two o'clock in the morning. Finally, he successfully completed the 2021 college entrance examination.
To live is much more difficult than others. Why does he have to learn? The family said because of the serious disease, he was deprived (剥夺) of the right to walk, run, jump, but he can no longer be deprived of the right to education. Xing Yifan decided to let himself be Hawking of China, and change his life with knowledge.
He came to BUAA and stayed in the love dormitory on the first floor. Xing Yifan said he was feeling particularly warm with all the help. He was expecting new college life and hoped to know more students, and take part in lots of activities. Life kisses him with pain, but he sings.

2 . 72 Hours in Beijing
Traveling to China is no longer a luxury for many foreign passport holders. The Chinese government has permitted a 72-hour visa-free policy that offers access to visitors from 53 countries including the US, France and Austria. Let’s start with the capital of China, Beijing. Here’s a pick of the best in Beijing!
Mutianyu Great Wall
Your trip to Beijing isn’t really complete without seeing one of the “New Seven Wonders of the World”, the Great Wall of China. The Mutianyu section of the Great Wall is by far the most well-preserved of all. Taking a one-hour bus ride Mutianyu would be your ideal location for a half day of hiking away from the large crowds in the city. Also the authorities have allowed tourists to paint graffiti on a specific section of the Great Wall since 2014. The Great Wall was designated a UNESCO World Heritage site in 1987.
798 Art Zone
This would be on the top of my list! Named after the 798 factory that was built in the 1950s. The art zone is home to various galleries, design studios, art exhibition spaces, fashionable shops and bars. You could easily spend half your day wandering around the complex, feeling the contrast of the present and the past.
Summer Palace
Located in northwestern Beijing, the Summer Palace is by far the city’s most well-preserved royal park. With its huge lake and hilltop views, the palace offers you a pastoral escape into the landscape of traditional Chinese paintings. The Summer Palace was added to the UNESCO World Heritage List in 1998.
Sichuan Provincial Restaurant
While in Beijing, apart from trying the city’s best-known Peking duck the Sichuan provincial restaurant is one of the places where you can enjoy regional delicious food. It offers one of China’s eight great cuisines, Sichuan, which ranges from Mapo tofu to spicy chicken.
1. Which of the following is true about the Mutianyu Great Wall?| A．You can paint graffiti anywhere. |

4 . E-cigarettes can damage vital immune system cells and may be more harmful than previously thought, a study suggests. Researchers found e-cigarette vapour disabled important immune cells in the lung and boosted inflammation (炎症).
The researchers caution against the widely held opinion that e-cigarettes are safe. However, Public Health England advises they are much less harmful than smoking and people should not hesitate to use them as an aid to giving up cigarettes.
The small experimental study, led by Prof David Thickett, at the University of Birmingham, is published online in the journal Thorax. Previous studies have focused on the chemical elements of e-cigarette liquid before it is vaped.
In this study, the researchers designed a mechanical process to mimic (模拟) vaping in the laboratory, using lung tissue samples provided by eight non-smokers. They found vapour caused inflammation and impaired the activity of alveolar macrophages cells (肺泡世噬细胞) that removed potentially damaging dust particles, bacteria and allergens. They sail some of the effects were similar to those seen in regular smokers and people with chronic lung disease.
They caution that the results are only in laboratory conditions and they are planning to do more research to better understand the long-term health impact the changes recorded took place only 48 hours.
Prof Thicket said while e-cigarettes were safer than traditional cigarettes in terms of cancer risk, they may still be harmful in the long-term. If you vape for 20 or 30 years, you can suffer from COPD (chronic obstructive pulmonary disease), then that’s something we need to know about.

5 . While the start of a new school year is always exciting, this year was even more so for some elementary school students in Auckland, New Zealand. They became the world’s first kids to be “taught” by a digital teacher. Before you start imagining a human-like robot walking around the classroom, Will is just an avatar that appears on the student’s desktop, or smartphone screen, when ordered to come.
The autonomous animation platform has been modeled after the human brain and nervous system, allowing it to show human-like behavior. The digital teacher is assigned to teach Vector’s “Be sustainable with energy”— a free program for Auckland elementary schools.
Just like the humans it replaced, Will is able to instantly react to the students’ responses to the topic. Thanks to a webcam and microphone, the avatar not only responds to questions the kids may have, but also picks up non-verbal cues. For instance, if a student smiles at Will, he responds by smiling back. This two-way interaction not only helps attract the students’ attention, but also allows the program’s developers to monitor their engagement, and make changes if needed.
Nikhil Ravishankar believes that Will-like avatars could be a novel way to catch the attention of the next generation. He says, “I have a lot of hope in this technology as a means to deliver cost-effective, rich, educational experience in the future.”
The program, in place since August 2018, has been a great success thus far. Ravishankar says, “ What was fascinating to me was the reaction of the children to Will. The way they look at the world is so creative and different, and Will really captured their attention.” However, regardless of how popular it becomes, Will is unlikely to replace human educators any time soon.

7 . The flying fox is not a fox at all. It is an extra large bat that has got a fox’s head, and that feeds on fruit instead of insects (昆虫). Like all bats, flying foxes hang themselves by their toes when at rest, and travel in great crowds when out flying. A group will live in one place for years. Sometimes several hundred of them occupy (占据) a single tree. As they return to the tree toward sunrise in the morning, they quarrel among themselves and fight for the best places until long after daylight.
Flying foxes have babies once a year, giving birth to only one each time. At first the mother has to carry the baby on her breast wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls down to the ground and squeaks (尖叫) for help. Then the older ones swoop (俯冲) down and try to pick it up. If they fail to do so, it will die. Often hundreds of dead baby bats can be found lying on the ground at the foot of a tree.

10 . Until now, scientists haven’t been able to study the new rock on the moon.The new samples from Chang’e 5 will change this. They’re from near Mons Rümker, a volcanic mountain where the rock is thought to be much younger-- about 1 billion years old.
There are a lot of reasons scientists are eager to study this younger rock, one of which is that it could help us more precisely date not only the moon, but many rocky planets and other objects.
Here’s how that works: Scientists date lunar rock by using something called a chronology curve（年代学曲线）, says Jollliff, a scientists at Washington University in St. Louis. Basically, they estimate the age of the rock by counting the number of craters（火山口） in the area the rock comes from; those increase as objects strike the rock over time. To make this estimation, scientists need to match the number of craters to a precise age. Right now, they only have data points for lunar rock that is 3 to billion years old. Modern techniques can date the new sample extremely accurately, and once scientists know its precise age, they can add a valuable data point to their chronology curve. The dating system will also help us more accurately estimate the age of all sorts of objects in space, like rocky planets and other moons.
Another reason scientists are keen to study this young volcanic rock is to find out more about how volcanism works on the moon. Jollliff says that it’s unclear why there was volcanic activity on the moon for such a long period of time. Most of the moon; s volcanic activity, he says, is thought to have occurred 3 or 4 billion years ago, when the moon was still pretty young. But since the moon does not have plate structure, which drives volcanism on Earth, it’s unclear what could have caused much later volcanic activity. “That’s something that you can find out of the samples by studying them in the lab,” Jollliff says.
