【推荐1】Here are some superheroes in the fight against COVID-19 (新冠肺炎). Let's come close to them and remember them.

	Zhong Nanshan(1936.10-) He is one of the famous medical scientists in the 21st century. Dr. Zhong Nanshan was the first to tell the public that the virus could be transmitted from person to person. He is a good doctor in the countrymen's eyes and respected by all Chinese people.
	Li Lanjuan (1947.09-) When COVID-19 broke out, she suggested that Wuhan should be locked down immediately to prevent the spread of the disease. She headed for Wuhan and took an active part in the battle. Now, she still receives patients every day.
	Wang Yong (1985.12-) As a delivery (快递) driver, he volunteered to support the medical staff in Wuhan during the epidemic (疫情). He tried his best to keep life going for the doctors and nurses. Time magazine has put on its cover, presenting the courage and hard work of common people.
	Li Wenliang (1985.10-2020.02) He is the first doctor to warn people how dangerous the virus could be at the end of last December, so people call him the "whistle-blower (吹哨人). Because of COVID-19, he lost his life on February 7 th, 2020. People across the country were sad to hear about his death.

“The surgical masks are cut into smaller squares that can be filled into the plastic mask to serve as a filter (过滤器) ,”said Dusty Richardson, a surgeon at the Billings Clinic. “The filter can be used for a day and you can substitute it the next day, but I do wash it for the next use,” Richardson added. The plastic mask and filter can be cleaned with soap, bleach (a chemical that is used to make something become white) and other cleaning chemicals. Richardson believes healthcare workers can get six to ten uses out of a single surgical mask.

Richardson came up with a prototype (原型) of the mask and worked with surgeon Spencer Zaugg and Spencer’s son Colton to make the design become a reality. They’re all really into 3D printing and Colton has design experience and was able to adapt a pattern he found online.

“Spencer and Colton have four 3D printers,” Richardson said. “They have created at least 15 masks so far.” Public schools in Billings are closed because of COVID-19, but some teachers went back into their classrooms on Monday to start printing out masks on their schools’ 3D printer. It takes a few hours to print a single mask.

Richardson said the files and instructions are posted online so anyone can make the masks on their own 3D printer. “I got a text from someone who printed one out in Scotland and is even working on it overseas,” Richardson said.

They’ve already made one huge improvement to their design. A company called HiTech Filters heard about the project and said that they could mass-produce filters using hospital-grade high-efficiency material quickly without wasting precious surgical masks.

“We’re just trying to help people here,” Richardson said. “We want healthcare providers and patients to be safe.”

To help stop the spread of coronavirus, health officials recommend avoiding large gatherings and maintaining a distance of 1-2 meters from other people. Social distancing places no such location constraints; rather, it is a behavioral practice to lower the risk in most circumstances.

A number of companies asked their employees to work from home, with some of them having carried out remote work policies. This unexpected experiment has been so well-received that employers are considering adopting it as a more fixed measure. For some digital-based sectors, working from home has instead been surprisingly effective.

Everybody has been trying to recover from the impact of COVID-19 in 2020 by remote working, online education, social distancing and more. Countries suffering from the coronavirus are trying to recover. Many of them have promoted tax and fee reductions, improved the business environment, and inspired the enthusiasm of market players.

The World Health Organization declared in March that the spread of COVID-19 had become a pandemic. More than 200 countries and territories around the world have reported confirmed cases of the coronavirus. Global health authorities and vaccine developers are currently partnering to support the technology needed to produce vaccines(疫苗).

It was a year when the whole world had to collaborate and work together in unity to overcome challenges faced by all of mankind. Some of these major events include severe natural disasters, economic recession（衰退）and COVID-19. These events have brought the world closer, allowing billions of people across the world to experience the true power of a united mankind.
