Spring is here, and it is time to enjoy West Lake Longjing tea. Usually, we think of workers picking tea leaves by hand. But now, some Longjing tea is being picked by smart tea-picking robots!
In a Hangzhou tea garden, a smart tea-picking robot developed by Zhejiang SciTech University begin to work for the first time. “We took thousands of pictures of new tea buds (芽) and put them into the robot for it to learn. The robot uses an AI model to recognize (识别) the buds it needs to pick,”said Professor Chen Jianneng, Party branch secretary (党支部书记) of the research team. This lets the robot find the right tea buds about 90% of the time.
The robot’s arm pulls and sucks (吸) up the tea buds. These buds are quickly moved into a special box. After the robot collects all the buds from the area it’s working at, it moves the buds from the box to a main box.
The robot was made because there are not enough people to pick tea leaves. In Zhejiang, about 400,000 more pickers are needed now. “Picking is the biggest challenge for the development of the tea industry,” said Professor Wu Chuanyu, who leads the research team.
“Tea-picking robots are a trend (趋势) of the future,” said Wu. About five years from now, the robots will do the job of picking West Lake Longjing tea instead of people, Wu added.

Researchers at an American university are working to create special chewing gum (口香糖) to help reduce the spread of COVID-19.
Experts agree that vaccinations (接种疫苗) are the best way to fight against COVID-19.
“This chewing gum is made from plant-grown ACE2 protein, a special material which can neutralize (使无效) the virus in the mouth. In other words, when the virus comes in the mouth, ACE2 protein stops it there,” Henry Daniell, the leader of the research, explained. “So, the virus does not reach inside the body and the infection stops there.”
The research is still in its early stages, and the researchers are planning to carry out a clinical trial (临床试验) in humans to decide whether the gum is safe and effective.
“We are already using masks and other things to reduce the chance of spread,” Daniell said.
| A．If it works, the gum could reportedly be used in many situations. |

【推荐3】Have you ever wondered what animals are thinking when you see them? Do you feel happy when you see a cute dog, but do they feel the same way? It’s hard to tell what animals are thinking because they have no ability to speak like us.
Humans have many different feelings, but it’s difficult to understand what animals are feeling. We might think we know our pets the best because we spend a lot of time with them. Some people have dogs as pets because they are friendly to us, even love us. But love could just be a human feeling. Professor Kim Bard did an experiment to test pets’ feelings. It turns out that some dogs show the same feeling when their owner pretends (假装) to cry, but not with strangers. However, it’s harder for cats to work out.
Other animals, like giraffes and whales, also experience great sadness when someone in their group dies. Nowadays, people are starting to consider their well-being more. In the UK, new legislation (立法) means all animals will be considered in law as sentient living things, even tiny insects. Research shows they can feel a degree of feelings, such as being happy, sad, angry, or frightened.
Dr Barbara J King says, “If we understand how deeply animals can feel feelings, do we really need zoos around the world? This is a question.” Understanding animal feelings is important because it helps us treat them in a proper way.

【推荐1】Susan Boyle was born as the ninth child in a Catholic family. She suffered from learning disabilities ever since her birth because of her mother's poor health.
School was difficult for Susan and she was bulled（凌辱） because of her different behaviour.Her siblings,who were much older,had life experiences that were unknown to their little sister.From the time of her birth,Susan was a screamer.The only really safe place that she would use as a repeat was her bedroom.There she would hang posters of her musical heroes on the walls and sing popular music into a hairbrush that she pretended was a microphone.
One by one her brother and sisters moved away from home and then Susan's father died.This left her alone with an old mother and a cat.She tried volunteer work.Her best state of mind,however,was found when she was singing and so she would regularly join others in karaoke or pubs where she could show her skills and receive appreciation（欣赏）from the crowd.

There is probably nothing scarier than fighting an enemy that you cannot see. The COVID-19 is one of these enemies, and it has done quite a bit of harm.
But even if we cannot see the virus, we know how it acts and spreads around, which is just like most other viruses. “The number one thing you can do to prevent any respiratory (呼吸的) illness is to practice good personal hygiene (卫生).” Tom Moorcroft, expert in Origins of Health, told CNET.
It’s important to wear a mask and wash hands. By wearing a mask, you keep yourself away from the droplets (飞沫) coughed and sneezed by infected people. These droplets can spread the virus -- as far as two metres! But these droplets don’t stay in the air for long before falling and landing on surfaces, like tables and smartphones. They can also be transferred to elevator buttons and door knobs by our hands. So it’s important to wash hands.
It’s reported in People’s Daily that the virus might be contagious (接触传染的) even before patients start feeling sick. “The result is that there are no ways in public health to find out or to identify people at risk of transmitting (传染), because they don’t even know if they’re ill yet,” Gerard Krause, head of the Department for Epidemiology at the Helmholtz Centre for Infection in Germany, told Al Jazeera.
Indeed, infectious diseases can be scary. But if there is anything right that we can learn from this epidemic, it’s that we’ve developed better hygienic habits. After all, washing our hands is actually what we should do every day.
1. What is TRUE about droplets?| A．Healthy people’s droplets can spread the virus. |
| B．Droplets can spread the virus as far as two metres. |
| C．Droplets can’t be transferred to elevator buttons. |
| D．Droplets can really stay in the air for a long time. |
| A．they can’t see a doctor | B．there are not enough hospitals |
| C．they don’t feel sick at all | D．they aren’t afraid of the disease |
| A．The COVID-19 | B．An expert in Origins of Health |
| C．Infectious diseases are scary | D．Practice good personal hygiene |
