1 . Windy days are common during spring. Did you know that strong winds can even influence trains?
On May 1, 2021, strong winds in Baoding, Hebei Province, caused a foreign thing to get caught in power lines above the railway lines, stopping some trains. Some passengers were even stuck on their trains while traveling.
High-speed trains receive power from wires (电线) hung above the railway lines, according to Worldwide Rails, a rail news website. As an important power source for high-speed trains, why are these lines so easy to break in the face of wind.
The line itself is strong, but too many light things can still influence them. Kite wires are one of the biggest problems for railway workers. If one end of a kite wire touches a power line and the other end touches the ground, it will cause a short circuit (电路) on the line, causing a loss of power.
Other materials, such as tin foil (锡纸), can also cause problems. If they are blown onto train power lines, they can stop trains from getting power.
In many cases, train workers have to remove foreign things from power lines themselves. The bigger the foreign thing is, the harder it is to clean up. Bird nests are one of the most difficult.
Because of their height and strength, power lines have become a popular place for birds to make homes. Birds carefully make their homes with branches and other materials. “They keep us busy. One day we deal with one bird's nest and the next day they’ll build another,” a Xiamen train worker told Xiamen TV. How to solve? To make man-made nests and put them along the lines to fool birds into thinking the place is taken.

Chinese astronaut Wang Yaping made history on November 7 when she became the country's first woman to do a spacewalk, according to the national space agency.
At the moment, Wang and Zhai Zhigang, two of the three members at China's new Tiangong space station, successfully completed the 6.5-hour spacewalk in the early hours of the morning of November 8, according to the China Manned Space Agency. The third astronaut of the Shenzhou-13 members, Ye Guangfu, stayed on the space station to support the spacewalk.
It's the first time the astronauts have left the space station since their arrival on October 16. Shortly after stepping out of the spaceship, Wang waved to audiences on Earth and said she felt great. During the spacewalk, the team fixed a suspension（悬挂）device and connectors to the station's robotic arm. They also tested the safety of supporting equipment（设备）, including the spacesuit produced by China.
Wang is China's second woman in space, after Liu Yang made history by joining the Shenzhou-9 spacecraft in 2012. Before Wang, only 15 women around the world had done spacewalks since 1984, when Soviet astronaut Svetlana Savitskaya became the first to do so. So far, most women spacewalkers have been American NASA astronauts.
The Shenzhou-13 members will do one or two more spacewalks during their six-month stay at the space station. This is not the first time astronauts have worked at Tiangong space station. In September, three other Chinese astronauts successfully completed a three-month stay at the station. By December 2022, China plans to have the station ready to be used—a great target that seems to be possible.
1. The Shenzhou-13 members arrived at the Tiangong space station on October 16.2. During the 6.5-hour spacewalk, all the Shenzhou-13 members stepped out of the space station.

Every living thing needs to reproduce（繁殖）. Reproducing means creating more members of your group. In order for plants to reproduce, they have to spread their seeds（种子）to other areas. Plants have developed all kinds of ways to do this.
The simplest way is gravity（重力）. Many seeds are inside of fruit. When fruit gets too heavy, it falls from a tree to the ground. Sometimes animals will pick up the fruit and drop it in another area. That helps move the seed even farther away. Apples spread this way.
Other plants use wind to spread their seeds. Dandelions（蒲公英）are a good example of this. Dandelion seeds are so light that when wind blows, it carries dandelion seeds to new places. Maple（枫树）seeds also use wind. Their seeds are connected with long, thin leaves that look like wings. When the seed falls from the tree, its “wings” help it fly farther from the tree.
Some animals help plants spread their seeds. The animals eat the seeds. While the seed is in the animal’s body, it stays whole. When the seed leaves the animal, it’s in a new place.
Ants also help spread seeds. Some seeds have a special smell that appeals to ants. The ants bring the seeds back to their home, which of course is underground. They only eat part of the seed. They leave the rest of the seed underground. After that, the seed can start growing.
1. When fruit gets heavy enough, it will fall from a tree to the ground because of gravity.2. All plants can spread seeds by themselves.
3. Wind helps apple and dandelion seeds to fly farther to new places.
4. Some animals and ants eat seeds, and it is helpful for seeds to spread.

5 . It is well-known that silk was discovered in China. It is wonderfully strong, light and soft. As one of the best materials for clothes, silk has a perfect look and feel that no other materials can match.
There is a story about how silk was discovered. Lei Zu, the wife of Huang Di, was having tea under a mulberry tree when a silkworm cocoon (蚕茧) fell into her cup. As she tried to take the cocoon out, it started to unwind (展开) and the “line” seemed endless. She realized that the strong line could be used to make clothes. Then Lei Zu taught her people how to raise silkworms and how to get silk. In this way, the silk industry was born.
For hundreds of years after that, silk was only used by rich people. It was a symbol of identity and status (身份和地位). With the development of the silk industry, more silk was produced. It was no longer just for rich people. In the Han Dynasty, silk was transported as far away as Spain, Rome and many other countries. The trade road was famously known as the Silk Road, which connected China with the rest of the world.
Today, silk can be used for many kinds of things, not just for clothes but also for paintings, writing brushes, kites and even fishing nets. Wherever silk goes around the world, it is always warmly received.

8 . Nowadays we use apps (应用软件) to order food, learn English and shop online. But have you ever imagined that we could deal with garbage by using an app?
Dou Zheng, 15, a student in Beijing designed such an app. People can sell recyclable waste like bottles to garbage collectors. Just like ordering food, people can simply make an order on the app and enjoy door-to-door service. The idea for her app came from a real-life experience. On her way home, she always saw roads that were blocked because of garbage collectors. “There are lots of water bottles on the roads. It’s a complete mess.” she said. After doing research on surrounding communities, she found that the answer to the problem was to change the way people and garbage collectors trade.
Last summer holiday, she ordered a lot of food many times. That gave her the idea to design the app. To prove that it would work, she did surveys on Wechat and in the streets. The results showed that eight out of ten people thought the idea was good. However, she didn’t know how to program apps. She read many books and watched videos to learn about programming on her own. “It’s hard. I have to know what a number of codes (代码) mean and then write my own.” she said. Later, with the help of an app called AppMakr, she finished it! “This app made designing my app easier.” she said.
Her app may go online next year.
