2023暑假高二阅读专题练习：新型冠状病毒 一、阅读理解 In Billings, Montana, some healthcare experts are using 3D printers to make reusable plastic masks. What makes them special is that the masks are then fitted with pieces of surgical (外科的) masks which can be replaced when needed. “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.” 1．What is the biggest feature of the reusable plastic mask A．It is in the shape of a square.
