Many of them have had to learn new ways of performing their jobswhile attempting to turn living spaces into work-friendly environments. While such change can be difficult for anyworker, it can be even harder for a scientist or engineer who cannot work intheir usual laboratory setting. The American space agency NASA employs a largenumber of these workers. Almost all of them have been working from home for thepast month. Recently, the NASA team that controls theCuriosity explorer on Mars showed that they were able to perform their dailyduties completely from their homes. NASA recently reported on the team’s latestactivities on itswebsite. Usually, the Curiosity control team operatesfrom NASA’s Jet Propulsion Laboratory, or JPL, in Pasadena, California. But forthe first time ever, all members of the team have had to do all of theirwork remotely. Alicia Allbaugh leads the Mars ExplorationProgram. She said the current situation is very different from the environmenther team is used to working in at JPL headquarters. "We're usually all inone room, sharing screens, images and data. People are talking in smallgroups and to each other from across the room," she said. The Curiosity team has attempted to recreatethe same cooperative work atmosphere by using video conferencing technology andmessaging apps. Effective communication is very important. So, team leadershave added extra planning time each day to help make sure all team members areconnected. Carrie Bridge is the chief of scienceoperations for the team. She said one of her main jobs is to be a bridgebetween the scientists and engineers to make sure they understand each other’swork. Bridge said she is also now looking at about 15different message chats at all times to keep effective communicationflowing. "You're juggling more than you normally would,"she said. The remote Curiosity team was lacking sometechnology and tools they usually use to perform their jobs. Some employeeswere able to pick up some computer and communications equipment. But otherequipment could not be sent home. For example, the team uses special goggles, oreyewear, to examine three-dimensional (3D) images sent from Mars. Theequipment helps scientists get a better look at the surface of the planet sothey know where to drive Curiosity and how far they can extend the explorer’sarm. The gogglesrequire high-powered computer systems to operate that team members could notset up at home. So, they were told to use simple red-blue 3Dglasses instead. While not nearly as sensitive as theusual goggles, the team reported that the low-tech 3D glasses worked just aswell for planning drives and arm movements for Curiosity. After a lot of planning and test runs, theremote team was excited to announce that the explorer had received its commandsfrom Earth and performed as expected. The first result: Curiosity successfullycompleted a rock drilling operation in an area called “Edinburgh.” While the effort required a lot of creativethinking and workflow changes, Carrie Bridge said the experiencedemonstrated what NASA has always been about. "We're presented with aproblem and we figure out how to make things work. Mars isn't standingstill for us - we're still exploring." Questions: 1. What did Alicia Allbaugh say is oneof the main differences for employees working at JPL headquarters and workersat home? 2. What does the article say is amongthe main tools used by Curiosity explorer team members working from home? 3. What is the purpose of the specialgoggles described in the story? 4. What was the first major operationperformed by Curiosity that was controlled by team members working fromhome?

   公众号【外教在线英语】 官网【www.ai-talk.com】 LEMON TREE April 27, 2020 US Supreme Court’s ‘Next Big Thing’: theTelephone Exercise 1- Vocabulary pandemic -n. an occurrence in which a disease spread quickly around the world brief -n. a document that states the facts a lawyer plans to use in a court case branch -n. a major part of a government excited -adj. very enthusiastic and eager about something Excercise2 - Article US Supreme Court’s ‘Next Big Thing’: theTelephone The Chief Justice of the United States, JohnRoberts, said in2014 that courts will always be careful when it comes to “the next big thing”in technology. And it took a worldwide pandemic for the U.S. SupremeCourt to finally agree to use, of all things, the telephone. In May, the court’s members will hear argumentsover the telephone for the first time. Public television service C-SPAN willbroadcast audio of the arguments “live.” Clare Cushman is director of publications atthe Supreme Court Historical Society. She called the decision to use telephonesa “giant leap forward” for a place that sticks to tradition. But she noted thathearing arguments on the phone is somewhat backward given how much of thecountry and other courts are now using video conferencing. Until 1971, the Supreme Court was still usingpneumatic tubes to send documents. They were popular in the late 1800s forshipping mail, papers, and other things between offices. The court was stillusing Linotype machines to print documents in the early 1980s while othersprinted from desktop computers. Just two years ago, the high court made itsdocuments available on the internet, well after other courts. Before the coronavirus crisis, Supreme Courtjustices were exchanging messages and opinions on paper. Yet most of the ninejustices — six of them over the age of 65 — appear to use modern technology intheir own lives. Justice Elena Kagan has said she is on thesocial media website Twitter. Justice Samuel Alito has described readinglegal briefs on an Apple iPad. Justice Sonia Sotomayor wears anelectronic sensor that keeps watch over her health. And Justices Neil Gorsuchand Brett Kavanaugh have young children who might be expected to send textmessages to their fathers. This month, 81-year-old Justice Stephen Breyerused the videoconference service Zoom to talk to students at a New York school.Justice Ruth Bader Ginsburg is the oldest member of the court at the age of 87.She reads emails on an iPhone and once told people that she uses another Appledevice as a sound machine to help her sleep. Still, the decision to hear arguments viatelephone during six days in May was unimaginable two months ago. The change isan effort to limit large gatherings of people to slow the spread of the diseaseCOVID-19. This year, the cases before the Supreme Courtinclude President Donald Trump’s effort to keep his tax and financial recordssecret. The court also will hear whether Electoral College members must votefor the candidate who won their state in presidential elections. The court’s willingness to use telephones mightlast only a short time. But those who want more openness on the court hope itwill continue after the pandemic. Melissa Murray is a law professor at the NewYork University School of Law. She said live audio gives Americans the abilityto observe the third branch of the U.S. government at work. Sheadded, “I don’t know why you wouldn’t want that.” Stephen Dillard serves on the Georgia Court ofAppeals. He supports openness in the courts. He told The Associated Press,“This is a great first step, and I’m excited about it, but I hopethey will go further in years to come and allow live video streaming.” Questions: 1. Who was the The Chief Justice of theUnited States in 2014 who mentioned about the next big thing in technology? 2. How will it be helpful? 3. How is technology very helpful whenthe pandemic, coronovirus, paralyzed education and business operations?

The girls - ages 14 to 17 - are members of aprize-winning robotics team. They say they are on a life-saving mission.Somaya Farooqi is among them. “If we even save one life with our device, wewill be proud,” she said. On most mornings, Farooqi’s father drives thegirls to a workspace outside the western Afghan city of Herat, where they live.The trip takes careful planning to avoid police roadblocks set up to enforcestay-at-home orders for people in Herat. There are a limited number of special permitsto avoid the police stops, but Farooqi’s father has not been able to get one.The girls say they have to work fast so they are willing to take risks totravel outside the city. “We are concerned about security driving out of thecity,” Farooqi said. But there is no other way, she said, adding,“we have to try to save people’s lives.” The team’sefforts would have been unthinkable in Afghanistan just a generation ago. UnderTaliban rule in the late 1990s, girls were not permitted to even go to school.Farooqi’s mother was forced to leave school in the third grade. After the United States invaded Afghanistan in2001, girls were permitted to return to schools. The struggle to gain equalrights for females continues and the young engineers push forward with theirwork. “We are the new generation,” Farooqi said. “We fight and work for people.Girl and boy, it does not matter anymore.” Afghanistan is facing the coronavirus crisiswith limited supplies of medical equipment. The country has just 400ventilators for its population of more than 36 million. So far, the country hasreported more than 1,000 cases of the virus, and about 30 deaths. But expertssay the number of cases are likely much higher since virus testing remains verylimited in the country. More coronavirus cases have been reported inHerat province because it sits close to the border with Iran, which hasexperienced a severe spread. The local spread of the virus led Farooqi andher team to try to come up with a medical solution. At their workspace, theteam has experimented with two different designs. One of them is based on plansdeveloped by engineers at America’s Massachusetts Institute of Technology(MIT). Parts usedto build the ventilators include the motor of a small car device,car batteries and sets of oxygen pumps. A group of auto repair expertshelps the team build the ventilator structure. DanielaRus, a professor at MIT, welcomed the team’s quick development efforts. “Itwill be excellent to see it tested and locally produced,” she said. Afghan businesswoman Roya Mahboob founded therobotics team and raises money to empower girls in technology. She says shehopes Farooqi’s group will finish building a working model by May or June. Themodel will then be tested by the country’s health ministry, at first onanimals, a government spokesman said. Somaya Farooqi says her team felt the need toseek a solution to help people at home. “Afghans should be helping Afghanistanin this pandemic,” she said. “We should not wait for others.” Questions: 1. What breakthrough did the youngfemale engineers make in Afghanistan? 2. What parts did they use in makingsuch discovery? 3. What are the age brackets of theyoung female engineers? 4. Why is their invention beneficial? 5. How do their parents support them?
