1 . 5G technology would be widely used by 2020, causing some experts to say the “5G epoch” is coming. Yet, when reporting about 5G, many reporters only described it as a “much faster” technology than 4G. As a result, what people know about 5G is that they could “download a movie within one second”.
Actually, 5G technology has many more advantages than 4G besides the speed. It can be used for at least two purposes—for connecting everything and removing delays (消除网络延时).
Connecting everything is one of the strongest functions of 5G. It makes the Internet Things possible. Take driverless smart cars as an example. 5G technology can connect all parts of a transportation system including traffic lights, CCTV cameras and cars to build up perfect coordination (协调). In this way, these cars can avoid obstacles (障碍) and move on driving routes, which will help improve self-driving technology. And removing delays might be useful especially in online games. Factories can produce more macro base stations to allow more people to use. The more users, the lower cost. Therefore, 5G technology won’t cost as much as they thought.

2 . When spring is in the air, everyone looks forward to seeing the beautiful and eye-pleasing flowers and plants. The following flowers and plants might not be so eye-pleasing, but are certainly eye-catching!
Lady’s Slipper This flower is amazing. It looks like a shoe. To be more exact, it is like a lady’s slipper. That’s how it gets its name. Although it was once found across Europe and the UK, now Lancashire in England is the only place where this plant can be found. The flower was so unusual that people picked almost all of them. Besides, it is one of the most difficult plants to grow. Fortunately, strict rules have been made to protect this endangered plant. |
Hot Lips When you see a plant like this, don’t get shocked! No, they are not a woman’s lips! You can find these plants in countries with tropical (热带的) rain forests, such as Colombia, Costa Ricaand Panama. Because of the cutting down of trees, these unusual plants have become endangered. |
Black Bat Flower The black bat flower is an unusual flower that grows in the wild and tropical forests of Yunnan Province in China. It is famous for its bat-shaped black flowers. It needs special environmental conditions to grow. This is the reason why it is an endangered plant. You can consider yourself lucky if you actually see one of the plants mentioned above. After all, they are all endangered and disappearing from the earth. Hopefully, there are other unusual flowers that are left and undiscovered, because the world is full of surprising things! |

3 . The Internet has changed the world. People are able to get and share information in seconds. Nowadays, people begin to wonder: Is the Internet good or bad? “It’s impossible to answer that question because the Internet means so many things,” says psychologist (心理学家) Patricia Greenfield.
Some are truly wonderful. In many ways it makes life easier and simpler. It helps us get things done more quickly. It opens up the world to us. And if a friend lives far away, the Internet makes it easy to stay in touch.
However, the issue (话题) isn’t black and white. Some can become real problems if we don’t take care. Spending too much time online is harmful to people’s health. It may even cause them to be less social with family and friends. Apart from (除……之外) that, some people attack the web or use the Internet to steal others’ personal information, even banking information. Most of the young students think the Internet is simply an icon on the screen. Kids won’t realize that the Internet is a network of millions of computers until about 10 years old.
The Internet can be a useful tool, but don’t let it take up all of your time. Use the Internet properly (适当地) and carefully and it can make your life more colourful.

4 . People depend on plants. We use plants for food, cloth, and even the air we breathe (呼吸). Plants keep our air and water clean. Green plants give us oxygen. Oxygen is part of the air we breathe. Plants are also part of the water cycle (循环). Most of the water that a plant takes in goes back into the air. Plants give us a lot of the food on the earth. Fruits, vegetables and crops come from plants. Without plants, we would not have bread, rice, carrots, apples, oranges, or bananas!
Many people are growing plants to eat in their own gardens at home. Having your own garden helps the earth as well. When you grow your own fruits and vegetables, you help make less pollution (污染) because drivers don’t need to take your food to shops. You also help make less rubbish because you don’t need to use bags for packing your food. You can just pick it out of the soil or off a plant and put it into a basket!
Trees are important plants. Trees give us wood to build homes and other things. Trees are used to make lots of things around your home and at your school. And trees give us fruits that are good for health. Without trees, the earth would be a very different place.

5 . Do you know mukbang? It is about the eating shows in front of the camera on the Internet. In the shows, mukbangers eat food and sometimes talk to people who watch their videos.
The eating shows started in South Korea in around 2010 and there are many viewers (观看者) from all over the world. Why did mukbang start in this country? In fact, South Korea has the culture of eating together. But nowadays, eating alone is quite usual in the country. Watching mukbang can be a way to have someone to eat with. People can chat with others when they are at home alone.
However, mukbang has its dark sides. The way mukbangers eat food in some shows isn’t healthy. These bad eating habits can bring serious health problems. What’s worse, some mukbangers prepare a lot of food but throw away much food during the show or after the show. These mukbangers waste (浪费) a lot of food.
Now, many people criticize such shows. Food waste is a serious problem around the world, and there are lots of people who still don’t have enough food to eat. Our country does a lot of things to solve the problem and asks short video platforms (平台), such as Tiktok and Kuaishou, to take action.

6 . The Double Third Festival is an ancient Chinese festival. It comes on the third day of the third lunar (阴历) month, so it’s not on the same day every year. The day is said to be the birthday of Yellow Emperor (Huangdi). The date was fixed after the Wei and Jin dynasties.
In the Eastern Jin Dynasty, people often bath (沐浴) in the river on that day to wash away bad luck. Wang Xizhi wrote in his LantingjiXu about how people took a bath and wrote poems while drinking. In the Tang Dynasty, people enjoyed drinks and sightseeing. In the Ming and Qing dynasties, people did activities like throwing stones, hiking and listening to music.
In modern times, it is mainly celebrated by the people in the southern parts of China. For the Zhuang people in Guangxi, it is a festival for young people to sing songs and find their true love. Bamboo dancing is another important activity for them. For the Li and Miao people in Hainan, it is a day for remembering ancestor (祖先).

8 . Type in “A cat wants to go to space” and ask the robot to write a bedtime story. Just one second later, you’ll get the story of a cat called Max. He goes through many difficulties to sing among the stars.
This robot writer is real. It’s called ChatGPT. US company OpenAI made it. It can talk with people, write songs, poems and even jokes. It’s one of the most powerful (强大的) AI writers.
ChatGPT can write things really fast. We may spend hours researching, understanding and writing an article on the theory of evolution (进化论). But ChatGPT can write a good one in seconds. But if you ask harmful questions, such as how to make weapons (武器), it will not give you an answer.
ChatGPT comes along at a time when AI can do many creative (有创意的) tasks. The things they create are difficult to tell from those made by humans. This brings many problems, such as the definition (定义) of art. The robot is trained (训练) using words from the Internet, so it can also pick up on the Internet’s biases (偏见) about certain groups. These are all the things that humans need to solve.

9 . We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we will let others know soon. But do you know that a tree can talk and share news? It sounds strange, but it’s true that some trees can also communicate with each other. Of course, no tree moves lips and says words just as people do.
Willow trees (柳树) are the best-known of these trees. When insects (昆虫) begin eating a willow tree, the tree gives out a special smell at once. This smell tells the other willow trees that insects are coming near. All of them quickly make a chemical (化学物质) in their leaves. This chemical is bad for the insects. The insects do not like it and they fly away soon. In this way, the willow trees keep themselves away from the insect.
Next time when you take a walk near the trees, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees can “talk” to each other, too.

10 . Lots of kids have headaches from time to time. Most headaches will go away after you resting or sleeping. When you have headaches, the first thing you should do is asking mom or dad for help.
