Have you heard of the sandstorm? It is a natural disaster (灾难). It often happens in the desert. A sandstorm is like a snowstorm. They both bring a lot of trouble to people. In sandstorms, the wind carries the sand. Sandstorms are different from other disasters. They come with a warning (前兆) but other disasters come without any warnings. So when you see that clouds have a dark colour, it means there is going to be a sandstorm.
If it doesn’t rain for a long time, sandstorms may happen. When there are sandstorms in cities, there will be no planes in the sky. It would be dangerous for the pilot (飞行员) to fly the plane because he cannot see clearly. There would also be more traffic accidents in the street. The sky is grey and people cannot see very far.
There are many deserts in Africa and Asia. Sandstorms often happen in these places. People can stop sandstorms by planting trees.

Tilly, a ten-year-old girl, saved about one hundred other visitors in 2004 in a tsunami, a huge ocean wave. She knew what was happening because she learnt about underwater earthquakes (地震) at school only a few weeks’ earlier, a newspaper reported.
“I was on the beach and the water started to go funny,” Tilly told the reporter from the newspaper. “There were bubbles (气泡) and the water went back suddenly. I knew there was going to be a tsunami (海啸). I told Mum,” she said.
Tilly’s mother and the hotel workers acted quickly. They cleared people from the beach just minutes before a huge wave reached the land. Luckily, no one died.
Tilly’s teacher was very proud of her. “She’s a very clever girl. It is very lucky that we learnt about this kind of tsunami in our science class just two weeks before Christmas,” he told the newspaper.

Mars, Robots, Higher Prices and More
What will the world look like in 2045? I recently spoke with four American students, Caden Sorensen, Chandler Stark, Fatima Abdi and Noelani Velasco Polley, to get their thoughts on this question.
In 2045, the kids think, humans will be able to live on Mars. They suggest that everyone should spend a few years on the red planet to give the Earth a “rest”. “And when we come back, we must try not to pollute as much,” says Stark.
But Mars is not yet ready for human habitation (居住). The kids agree that immediate action must be taken to clean up the Earth. “It’s time to fix it now,” says Sorensen. “It’s not going to fix itself.”
The kids do not just care about progress in space exploration. They are also interested in the future jobs.
Stark hopes to compose (创作) music for TV shows one day. Abdi wants to be a business owner. Sorensen dreams about becoming a lawyer. Polley wants to be a scientist.
“I don’ t think there will be a lot of fast-food jobs,” said Abdi. She also thinks that everything is going to get a lot more expensive. “People will have to look for higher-paying jobs.”
Many jobs, the kids predict (预测), will be replaced by robots. “There’ll be no more factory jobs because robots can just do everything,” says Stark. But they believe the power to shape the future is in human hands. The world will be a better place, but of course, “we need to work hard, and we all need to learn to be kind to others.”
1. In the kids’opinion, where will humans be able to live in 2045?2. What is Sorensen’s idea about the Earth?
3. Why does Stark say there will be no more factory jobs?
4. What do you think the world will look like in 2045? Write 30 words or more.
An exhibition (展出) on the great Chinese ancient encyclopedia (百科全书) Yongle Dadian opened at the Lanzhou Museum in Gansu Province. It collected more than 7,000 kinds of ancient Chinese classics and records, covering literature (文学), art, history and geography from the pre-Qin period to the early Ming Dynasty.
With a total of 11,095 volumes (卷) and about 370 million words, the Yongle Dadian was regarded as “the largest encyclopedia in the world”. To protect this world-famous classic, Emperor Jiajing of the Ming Dynasty ordered a rerecording of it. The copying work took five years to finish. But hand-copied books have been gradually lost over the long period of history. Today, only over 400 volumes and a few pieces of the Yongle Dadian remain in the world.
The Chinese government promised to put greater efforts into digitizing (数字化) ancient books and encouraged libraries to open their collections for the public. This action certainly made the Chinese culture in ancient books “alive”.
Similarly, the Siku Quanshu, a collection of Chinese classical works, is being digitized in Lanzhou, Gansu Province. Created in the Qing Dynasty, Siku Quanshu had seven copies. But now, only three and a half copies remain. To bring them closer to the public, digitization efforts began in 2021 and are expected to be completed by 2024.
Ancient books are important to China in carrying on its cultural traditions and improving its cultural power. At the same time, they can also be used for researching and the development of cultural products.
1. What fields does the Yongle Dadian include?2. How many words are there in the Yongle Dadian?
3. Where can we find digitized Siku Quanshu at the beginning?
4. What do you think of the idea of digitizing books? Why? Write 30 words or more.
【推荐3】Nano-robots (纳米机器人)
In 2050, a small cloud floats (漂浮) through the air in a hospital room. In the room, a patient experiencing great pain from cancer(癌症), lies on a table. The cloud covers the patient's body and fills her lungs (肺). The cloud is not smoke or steam. It is made of millions of microscopic robots called nano-robots. These tiny robots move from cell (细胞) to cell in the patient's body, killing the cancer cells.
Fighting cancer with nano-robots is only an idea today, but scientists say that it would be possible in the future. Using nano-robots for good purposes such as fighting with disease or repairing the environment may be the solution to many of today's problems.
However, nano-robots could be a dangerous risk as well. Since nano-robots are so tiny, they will have to work in large teams of many thousands to many millions. For this reason, nano-robots will have to be programmed to build themselves. Scientists will not have the ability to build millions of nano-robots one by one. This ability to reproduce is making some scientists worried. What if something goes wrong in the programming? Quite a lot of crazy nano-robots would be far worse than any disease. Some people think that if they get out of control, nano-robots could kill the world.
What should be done? Should we continue researching nano-robots or should we search for other methods? This is one of the many difficult decisions that we have to make in the future.
