How do plants grow in space? An experiment (实验) on the Tiangong space station can provide the answer. Chinese astronauts have successfully grown rice in space. This makes it possible for astronauts to grow food to support long-term space stays.
“The rice plants are growing very well,” Zheng Huiqiong, a scientist at the Chinese Academy of Sciences, told China Daily. Since the rice experiment began on July 29, the plants of the tall shoot rice have reached a height of about 30 cm. They’re much taller than the box, which is about 14 cm. Plus, the plants of the dwarf rice (短杆水稻) have grown to around 5 cm.
Although there have been other rice experiments in space, the one on Tiangong is different. For the first time in history, the experiment aims to produce the whole life cycle (周期) of the rice. It begins with a seed (种子) and ends with new seeds produced.
The astronauts will keep watching the plants. If the experiment is successful, they will collect the newly produced seeds and bring them back to Earth for further studies, Zheng added.
Since the 1980s, China has been taking the seeds of crops to space. But growing rice in space is a different challenge because of the bad conditions of space. Micro-gravity, no enough air and high-energy space rays may make the plants difficult to grow.
Rice has been a main food for astronauts for a long time. US astronauts on the Apollo 11-the first humans to land on the moon in July 1969-ate cold dried chicken and rice during their trip to space.
If such an experiment goes well, astronauts will be able to plant their food in space. They don’t need to take a large number of food with them for their space travels.

【推荐1】The new and publicly-available ChatGPT is a type of AI that has been “trained” by looking at over 8 million web pages. When asked a question, ChatGPT uses this training to produce detailed (详尽的) answers as if they were written by a human. You can ask it anything and it will give you answers to not only follow-up questions but also professional questions (although it does sometimes make mistakes). You can also ask it to write text, such as short stories or essays. The technology is so promising (有前途的) that some people believe it will overtake Google in the near future.
For many years it has been expected that AI will become an important part of our lives, and for just as long there has been concern (担心) of the trouble that AI could cause. In the 20th century, scientists, philosophers and writers sometimes worried that AI would become too powerful. In the short story I Have No Mouth, and I Must Scream, a very large supercomputer has killed every human on earth except five people it keeps to torture (折磨). And in the 1984 film The Terminator, a powerful AI called Skynet used time travel to send a robot into the past to try to kill the mother of a brave and strong fighter against AI. On the other hand, some people were optimistic (乐观的) about advanced technologies’ potential (潜力) to build a better world. In the 1960s TV show Lost in Space, a family of humans were helped by a friendly robot named Robby.
Nowadays, there is less concern of an all-powerful AI trying to destroy the world, and we are not expecting friendly robots just yet. That doesn’t mean there is not a lot of excitement and concern being felt towards new technologies like AI, though. ChatGPT is a great example of a modern technology that is causing mixed feelings.
It’s too soon to say what kind of influence ChatGPT will have on our lives. Let’s hope that, if ChatGPT does become bigger and more popular, its effects are mostly positive (积极的). So, what do you think? Will ChatGPT be good, bad, or somewhere in between for humans?

Along the River During the Qingming Festival
Walking into the China Pavilion at Expo 2010 in Shanghai, people were amazed by seeing a huge digital(数码的) painting. Scientists digitised(数码化) the famous painting Along the River During the Qingming Festival by Chinese artist Zhang Zeduan.
The original(原先的) painting shows life during the Northern Song period and it includes many details of ancient Chinese customs, lifestyle sand technology.
▲ Farmers work in the fields, sailors move around their boats and people eat and do business in restaurants. Parts of the background are also animated(做成动画). You can see the wind blowing through the trees and across the water. These animations perfectly combine modern technology and ancient art.
Digital technology allows today’s artists to express their ideas in ways that ancient artists would not believe possible. Techniques such as animation, and 3D digital projection(投影) make art come alive.
Dunhuang Cave Paintings
Dunhuang Caves, which are protected ancient treasures in the Gobi desert in Northwest China, are filled with paintings and sculptures with lasting value. This artwork was created over a period of around 1,000 years.
The good news is for art lovers who cannot travel and for the caves. Scientists have created a 360-degree, 3D digital projection of the caves, which makes the artwork come alive. There is also a function(功能) that lets viewers zoom in and enjoy the paintings and sculptures in greater detail.
Digitising ancient art allows us to explore the ancient practices. It also makes the whole world understand the art while protecting the original artworks for the future.

【推荐3】With the development of science, more and more people are confused whether it is good or not to make robots. Are robots going to take place of human beings?
Every coin has two sides. Robots can be good to our society and life. At the same time, they also have some bad effects on our daily life. In my opinion, the advantages of robots are more than the disadvantages.
First, robots make our life more convenient. We can do many things that we didn’t have the ability to do in the past by using robots. That makes our daily life more effective.
Second, robots can be used in industry. Factories can reduce the cost of production by using robots. Robots do not need to eat and they will not be ill. That’s very good for producing goods.
Third, robots can save more people when a disaster happens. Because they can’t feel pain and they can save more people without feeling tired.
In a word, the world is changing. We should also change our thought to accept robots to become part of our lives. That can make our lives more colorful.
1. In the writer’s opinion, how many advantages do robots have?A.Two. | B.Three. | C.Four. |

The Healthy Food Pyramid(金字塔) is a simple guide to the types and proportion(比例) of foods that we should eat every day for good health. It contains the four main food groups, according to how much they contribute to a balanced diet based on the Australian Dietary Guidelines.
The bottom layers make up the largest part of the Pyramid because plant foods should make up the largest part of our diet—around 70% of what we eat! Plant foods contain a lot of nutrients(营养物) like vitamins and minerals(矿物质). Older children, teens and adults should aim to have at least 2 serves of fruit and 5 serves of vegetables each day. The middle layer includes the milk, yoghurt, cheese, meat, fish, eggs, nuts, and legumes(豆类) food groups. Foods in the milk, yoghurt, cheese primarily provide us with calcium and protein(钙和蛋白质), plus other vitamins and minerals. These foods are our main sources of protein. But each food also provides a unique mix of nutrients, including iron, zinc, B12 vitamins and healthy fats. We should aim to have a variety of animal and plant-based choices from this food group. The top layer refers to healthy fats. We need small amounts of healthy fats every day to support heart health and brain function.
Two more healthy suggestions. Water is the best drink and cooking your own meals at home and choosing minimally processed foods will help limit added salt and sugar.
