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1】Is your TV connected to the Internet? What about your chair, or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called “Internet of things”.
The Internet of things may be coming sooner than you think. Earlier this year, Samsung CEO spent a lot of time talking about the Internet things. He said that four years from now, every Samsung product will be part of the Internet of things, no matter whether it’s a remote control or a washing machine.
So, how do household（家用）objects that are part of the Internet of things work? Well, think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold.
An Interet-connected camera could help people feel safer in their homes. It can know people’s faces and has an infrared sensor（红外传感器）, so even if it’s dark it can see when someone passes by and send you a message on your smart phone to let you know who’s there. If the person is someone you don’t know, it can tell you that, too.
But according to MIT Technology Review, whether companies are connecting dog food bowls or security （安全）systems to the Internet, there may be some problems. For example, many early connected-home objects don’t have much built-in security, which means they could be hacked（被黑客攻击）. Moreover, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2015.
So, picture this: you enter your home. The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think.

At the moment of 9:43 a.m., on Tuesday, June 23rd, 2020, at the Xichang Satellite Launch Center (卫星发射中心) in Sichuan Province, the last satellite of the third-generation network (第三代导航系统) was sent into space. It is the 55th member in the family of BeiDou. It belongs to China’s Beidou Narigation Satellite System (BDS北斗卫星导航系统). So far, 59 satellites, including the first four test ones, have been launched from Xichang. With the development of China, we have already owned three other famous satellite launch centers-Jiuquan, Taiyuan and Wenchang.
After a period of tests in space, this new satellite has started to work with other Beidou satellites together. It is designed to work for at least 12 years. So far, China has completed the third-generation network of China’s BDS. It was a new milestone in the nation’s space research work. The launch showed our country has completed our largest space-based system. It’s one of four global navigation networks; including the United States’GPS, Russia’s GLONASS and the European Union’s Galileo.
BDS has been widely used as public resources in our daily life. It has been shared by the whole world. It will offer more services around the world. BDS is the common wealth of the development of human beings.

Imagine having an ear made out of an apple. It seems like a crazy idea from a horror movie. But it could happen in the near future.
Canadian biophysicist Andrew Pelling used an apple to grow a human ear. He thinks fruit and vegetables can be used to cheaply repair human body parts in the future.
Scientists have been trying to grow organs in labs to replace our old ones. But it is a hard job. For example, liver cells can grow in a lab, but the cells still need things like blood vessels to actually work. These things have to grow inside a scaffold called the extracellular matrix.
In the past, scientists have used man-made materials, animal parts and even dead people as scaffolds. But that has proved to be complicated and expensive.
Pelling and his team, however, found the apple to be a cheap and easy-to-use scaffold.
They first cut an apple into the shape of an ear. Then they used a special way to take out the apple’s cells and make it a scaffold. The team then added human cells to the apple, and watched it grow.
“You can implant these scaffolds into the body, and the body will send in cells and a blood supply and actually keep these things alive,” Pelling said during a Ted Talk speech.
The team put the apple scaffold inside a living mouse and the mouse’s cells slowly took over the pieces of apple.
Now Pelling is thinking of other fruit, plants or vegetables to use.
He says that the shape of flower petals could be perfect for repairing skin. And asparagus could fix a broken spine.

【推荐3】An underground garbage station at Changling Village in Luchu District was put into use on 30th, June, becoming the first one of its kind in Guangdong Province. It is developed by a Shenzhen-based company, Sagncity Environment. It only covers an area of three hundred square meters, while the traditional station covers around 500 square meters.
When garbage bins arrive at the station, workers at the site will first connect them to an above-ground container, about the size of a washing machine. The garbage bins will then be turned over automatically a the waste is being sent into an underground container.
During the process,water and liquid deodorant(除臭剂) will be used to control dust and to avoid bad smells. Dirty water produced from the garbage is collected in a special container and then is poured into the city’s pipes of the dirty water to further control smells. During the COVID-19 epidemic, a disinfection(消毒) system was launched to disinfect garbage and avoid the spread of the virus.
One underground container can hold 10 tons of garbage. The station which has two sets of the garbage transit equipment can store 20 tons of garbage at a time and it is able to serve 30,000 citizens. The whole machine is smart. When the underground container reaches 85 to 95 percent of its capacity(容量) a signal will be sent to tell that it is time to send the container to a final waste site. Additionally, when the smoke detector(检测器) is triggered(触发) or the monitored temperature is too high, the fire equipment will automatically work to make sure of safety. Noise is also well controlled at the station. The noise is little when the machine is working.
When the whole system stops working, there are only two washing-machine-sized containers seen in the area, surrounded by flowers and plant. At present, only one person is needed to manage the whole station.

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. |
| B．But it’s also known that vaccinated people can still spread it. |
| C．That’s why this chewing gum is special. |
| D．Before bringing their chewing gum to market, researchers have to decide how much of it should be used each day. |
| E．This gum could be used as another tool to win this fight. |
