A small cloud moves slowly through the air in a hospital operating room(手术室). In the room a patient with cancer lies on a table. The cloud is all around the patient, covering her body and filling her lungs. The cloud is not smoke. It is made of million of nano-robots(纳米机器人). These tiny robots move from cell(细胞)to cell in the patients’ body, killing the cancer.
Fighting cancer with nano-robots is only an idea today but scientists say that it could be possible in the the future. Using nano-robots for good purpose such as fighting the illness or repairing the environment may be the way to many of today’s problems. In the future, scientists at Rutgers University believe that nano-robots will help operation because it is the transporter of biological elements such as DNA and proteins.
However, nano-robots cloud be a dangerous risk as well. Because 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 re-produce is making some scientists worried. What will happen if something goes wrong in the programming? Quite a lot of crazy nano-robots would be far worse than any illness. Some people think that if they get out of control, nano-robots could make the Earth gone.
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.

Have you ever thought about what astronauts eat when they’re in space? What would they eat if they had to travel all the way to Mars (火星) ? A lot of the food astronauts eat is processed (加工过的) because it’s simple to eat and easy to take into space. However, some vitamins (维生素) can break down if the food is stored for a long time. People may have health problems if they eat processed food every day.
Growing fresh food in space might help astronauts stay healthy. It would also give them more food choices. Fresh vegetables grown on Earth have many nutrients (营养物质) that processed food do not have. However, we don’t know if vegetables grown in space are the same. Another worry is making sure that these vegetables don’t have the bacteria or fungi (细菌或真菌) that could make people sick.
Luckily, we have a plant growth room called Veggie on ISS (the International Space Station). We used Veggie to find out if it’s possible to grow nutritious and safe food in space.
We used Veggie to grow red lettuce (红生菜) over three years. We compared these (ISS-grown) vegetables to those grown at the same time on Earth. They were grown under the same conditions as on the ISS. We did research on the leaves and roots of all the lettuce plants. And we did not find any differences in nutrients between ISS-grown lettuce and Earth-grown produce. This means that it is possible to grow nutritious and safe food on ISS and astronauts should be able to eat vegetables grown in Veggie without worrying about getting sick.
Even though our lettuce is safe to eat, we still need to work out two problems. Firstly, there are more bacteria and fungi on ISS-grown lettuce. The wet environment in Veggie is probably the reason. Secondly, there are some differences in nutrients between the vegetables we grew in different years. Plants can change with too much or too little water, but it is hard to water plants in zero gravity (零重力) . Therefore, we need to make sure that growing environments are consistent in Veggie. Then astronauts can be confident about the nutrients in their food during their long stay in space.

【推荐2】“This year, COVID-19 broke out again in many places in China. Shanghai is one of the worst cities among them.” To fight against COVID-19, Shanghai built many makeshift(临时的)hospitals in the city.
Inside a makeshift hospital, a group of 28 disinfection(消毒)robots were working busily. Each of them could work 24 hours a day without any rest.
At the same time, a group of 5G indoor multifunctional(多功能的)cloud robots were busy delivering food in the hospital. Each robot could send about 20 boxed meals at a time. They usually went to patients’ areas and waited for them to collect their food. “In the past, it usually took a worker about 20 minutes to send 20 boxed meals. Now the work can be completed in just 5 minutes with the help of these robots,” a patient said.
“The robots not only make our work much easier, but also help protect us from catching the disease(疾病),” said a worker in the hospital.
To win the fight quickly, the local government also put more than 200 robots into use at a makeshift hospital. Outside those makeshift hospitals, more and more unmanned cars appeared on the streets to help people.

【推荐3】To write a great news story, you have to make sure it is correct, relevant (相关的) and fresh.
For a start, all the information in a story must be correct. Not only the spelling and grammar, but also the facts.
Any mistakes that appear (出现) in a story can get a newspaper into big trouble.
For example, if a newspaper said that Yang Liwei was the first man to go into space, it would be wrong. He wasn’t the first. The newspaper would probably lose lots of readers because of that mistake.
A news story is not only correct, but also relevant to its readers. People are mostly interested in news that happens near to them. That is why you care more about what happens at your school than at American schools. It is also why newspapers in Beijing don’t talk about much news in Shanghai or Hong Kong.
Finally, news must always be fresh. When you pick up your evening newspaper, you want to read about news that happens that day. You don’t want to read about news from last week!
So, now you know what makes a good news story. Have a good look at our newspaper and see if it is full of good news. You can try writing a news story for our newspaper like a real reporter.
