1 . While most people were stuck at home last year due to the COVID-19 pandemic, feeling isolated, some young people were thinking outside the box and reached for the sky as they created an impressive work.
When Bilibili uploader Lin Xiao, had too many bags to carry, instead of asking someone for help, the then 18-year-old spent about nine months addressing the problem. He built a robot, which can follow him wherever he goes, and upon which he can ride. The robot’s name? Devil! The name comes from the background music Devil’s Swing (Remix) for the video game Bendy and the Ink Machine. It resembles a suitcase, which can follow Lin wherever he goes, day or night, and detect obstacles in its path. It can also be used for transport and even charges Lin’s electronic devices.
Lin did everything himself, from designing the robot with 3D modeling, manufacturing the physical parts and programming it, to assembling all the components and electronics. The robot has a steel structure, a 3D-printed plastic shell and two 2D laser and radar scanners. The brain of the robot is powered by Arduino, an open-source electronics platform, and computing and coding solutions from computer manufacturer Raspberry Pi.
Lin admits that Devil is not perfect, but he hopes that it can inspire his peers to believe “what you do matters” and that they can make a difference in people’s lives. He sees Devil as “a toddler who is learning to walk”.
Lin’s passion for robotics began in his first year at his high school, when a teacher, discovered his talent for working with computers. He provided full support to advance Lin’s skills and took him to various computer science competitions.

3 . When it comes to cooling the planet, forests have more than one trick upon their trees. A new study finds tropical (热带的) forests help cool the average global temperature by more than 1℃. “The effect is largely from forests’ ability to stockpile CO2. But around one third of that tropical cooling effect comes from several other processes, such as the letting-out of water vapor (水蒸气),” researchers reported on March 24 in Frontiers in Forests and Global Change.
“We tend to focus on CO2 and other greenhouse gases, but forests can not only keep CO2,” said Deborah Lawrence, an environmental scientist at the University of Virginia. “It’s time to think about what else forests are doing for us besides keeping CO2.”
“Researchers already know that forests influence their local climates through various chemical processes. Trees let out water vapor through their leaves and, like human sweating, this cools the trees and the things around them. But on a global scale, it isn’t clear how the other cooling works compared with the cooling provided by forests’ ability of keeping CO2,” Lawrence said.
So she and her colleagues studied how over-cutting would affect global temperatures, using data gathered from other studies. For example, the researchers used data to decide how much the letting-out of CO2 stored by those forests would warm the global temperature. They then compared those results with other studies’ results of how much the loss of other aspects of forests.
The researchers found that in forests at latitudes (纬度) from around 50°S of the equator to 50°N, the primary way that forests influenced the global average temperature was through CO2 store. But other cooling factors still played large roles.

5 . How to Handle an Argument with Your Family Members
We’ve all been there. A relaxed evening with our family members. A lot of laughing. And then, as if someone had sat on the TV remote and changed the channel, the mood shifts. No more warmth. Suddenly there’s shouting, a ping-pong of accusations(指责), deadly stares, and hostility(敌意) streaming from eyes like red laser pointers. Having a conflict with your family members is frustrating, and you may feel sad and depressed.
Do remember that as much as it might feel this way, you’re not in a court of law with your family members.
Do try to be an advocate of others’ feelings.
Don’t try to explain yourself. You often want to explain yourself when having conflicts with your family members, but you don’t have time. You’re being cut off and attacked again.
A.If you are looking for a new relationship |
B.Don’t attempt to prove yourself in the face of your loved ones |
C.The point of an argument isn’t to prove the others guilty or to win |
D.Rather than going in circles about what you think and how you feel |
E.Each accusation strikes deeper and deeper into your sense of justice |
F.Don’t talk about what happened as though you’re simply stating the facts |
G.Here are the do’s and don’ts when you are arguing with your family members |
6 . Like most tourists, I enjoy taking photographs on holiday and can’t wait to show them to my friends and family when I get back. But while for me they represent treasured memories, to others they are more often than not simply a collection of boring, badly composed, out-of-focus pictures. So this year I decided to do something about this by booking myself on a trip to Rome which included photography lessons.
The first time I went to Rome, I remember thinking that it was a fantastic place for photographers with a wonderful photo opportunity lying around every corner. Yet by myself I didn’t have a clue how to go about getting some good shots. Added to this was the fact that there were crowds of tourists everywhere, blocking all the best views. But this second time things were different. Antonio, my photography tutor, was on hand to give expert advice every step of the way. The first thing Antonio told our group was that the secret to creating a good photographic image rather than just a snapshot (快照) is to first take a long look at what you want to photograph. Our first port of call was Piazza Navona, where Antonio gave us advice about how to photograph the Fountain of Neptune. For the next couple of hours, we wandered around the historic center visiting many of Rome’s architectural highlights. I didn’t get at all tired, even though I was on my feet for such a long time. And I felt that I was really able to appreciate the sights as I had to look at each one so carefully in order to get good pictures. It felt like a whole new world had opened up to me.
I learnt an incredible amount over the next two days, as well as having a thoroughly enjoyable time in one of the world’s most beautiful cities. Maybe my friends and family will show a little more enthusiasm when I show them my holiday snaps from now on!

7 . From 7 to 4,400, the protection of the crested ibis(朱鹮)is successful.
The crested ibis is an elegant bird with a red face and claws. During the breeding(繁殖)season, you may notice its white feather turning grey. The color change is due to a kind of black powdery substance(物质)the bird gives out at this special time.
However, its population around the world dropped rapidly in the 1960s due to the loss of living areas and the use of pesticides and fertilizers. Their low breeding ability and weak ability against natural enemies further pushed them to the brink of dying out.
Back in the 1960s and 1970s, scientists thought the chances of bringing back the bird were not great. In 1963, Russia announced the bird’s dying out in the country and it hasn’t been seen on the Korean Peninsula since 1979.
There were only five wild crested ibises left in Japan in 1980. A captive(圈养的)breeding program was set up to increase the number of the group, but in 2003, Kin, Japan’s last crested ibis born in the wild, died. The only hope of saving the bird was left to China.
The crested ibis hadn’t been recorded in China since 1964. A group of five scientists still decided to find the bird’s historical living areas in 1978. Finally, in May 1981, a farmer in Yangxian County, Shaanxi said he had seen the bird and led the group to find the last seven crested ibises in the county.
Shortly after this exciting discovery, a special group was set up to protect the bird. The local government also stopped hunting, the use of fertilizers and pesticides, and land clearing near their living areas, which enabled the family of the crested ibis to enlarge. According to the incomplete data, its number in China in 2020 increased to about 4,400, with 4,100 located in Shaanxi, one of their biggest living areas. Its home range also increased from less than five square kilometers to 15,000. The crested ibis is among several species successfully saved from dying out.

8 . There’s no end to the work to do with improving diversity in children’s media, especially for storybooks. Children need to be able to see themselves in the characters of the stories they hear and read, at a stage where they’re building their understanding of the world around them.
Shachi Kaushik’s new book, Diwali in My New Home, brings the festival of lights to life for an immigrant community.
This picture book is for children aged 5 to 8. It speaks to Indian children’s experiences living abroad when they’ve experienced life in India. The story is about a girl, Priya, who loves being with family and friends to celebrate Diwali. But Priya and her parents began living in the United States this year, and no one seems to know about the holiday. Priya misses the traditions in India. As she joins the lights together and creates rangoli art(地画艺术), Priya introduces the festival of lights to her neighbors. And even though the celebration is different this year, it’s still Diwali.
Kaushik was a lawyer before she discovered the joy of telling stories to young children. Storytelling began when she volunteered in Texas, where she hosted a monthly storytime for children. Seeing the joy on the children’s faces inspired her to write children’s books.
When asked “What’s the secret to making children pay attention to stories?”, she said, “I would say the secret is to be present and not to be shy from acting, singing or dancing. Be a performer. While reading, use facial expressions and voice to add excitement to the story. Also try asking questions like ‘What do you think will happen?’. Let the little ones’ imagination flow. Lastly, try adding a finger play song and some dance moves to get those little ones into the mood.”
