Protesters strongly criticized a court ordertelling Apple to help unlock an encrypted iPhone. (APPhoto/Eric Risberg)The United States Justice Department says it has found a way to get information from an iPhoneused by a shooter inlast year’s mass shooting in San Bernardino, California.The Justice Department also said it no longer needs help from the iPhone’s manufac turer, Apple.The company had refused earlier demands by federal investigators for help in recovering data from the device.The government sought to require Apple to write new software programs to help investigators getthe data without knowing the iP hone’s password. The government believed the information wouldhelp it in its investigation of the San Bernardino shooting, in which 14 people were killed.Last month, a judge ordered Apple to help the government. But the Justice Departmentannounced this week it has beenable to collect data from the phone. It asked the judge to cancel her order. She did so on Monday.Last week, the government delayed another court hearingin the case. Officials said they neededtime to test a method that could help them gain access to the iPhone withoutApple’s assistance. That method was developed without the help of federal agents or Apple.Lawyers for Apple have said that the company wants to know how the device was unlocked.But the withdrawal of the court process could take away Apple’s ability to legally request details on the method the government used. It also is likely to raise questions among users of Apple productsand the technology industry about the strength of Apple’s security on its devices.Words in This Storydata – n. information such as texts, audio recordings, video recordings and picturespassword – n. a secret series of numbers or lettersthat allows you to use a computer system ordevicegain access – expression to enter a place or the storage area of an electronic deviceunlock – v. to make (something) available for use。

2019年12月大学英语四级听力VOA慢速英语(30)Medical Mistakes, Third-Leading Cause of Death in USA new report says medical errors are the third-leading cause of death in the United States.Researchers at Johns Hopkins University in Baltimore, Maryland, say medical errors cause more than 250,000 deaths every year.If the research is correct, it means deaths caused by doctors’ errors are greater in number than deaths by respiratory disease.That number also is higher than the 150,000 deaths yearly reported by the Centers for Disease Control and Prevention.The CDC keeps the official statistics about causes of death in the U.S. The Johns Hopkins researchers say the CDC's way of colle cting data “fails to classify medical errors separately on the death certificate.”Dr. Martin Makary is a professor of surgery at the Johns Hopkins University School of Medicine. He is also anauthority on health reform. He says there is no standardized method for collecting national statistics about such medical care problems.The CDC’s methods for following medical-error deaths were adopted in 1949, according to the researchers. They saythe record-keeping needs to be changed to account for medical mistakes.Dr. Makary said, "At that time, it was under-recognized that diagnostic errors, medical mistakes, and the absence of safety nets could result in someone's death."He added, "medical errors were unintentionally excluded from national healthstatistics" for that reason.The researchers studied death rate data from 2000 to 2008. They then took information about hospitalization rates from 2013. Using that data, they determined that medical errors caused 251,000 deaths each year out of more than 35 million hospitalizations.This, researchers say, represents 9.5 percent of all deaths in the U.S. each year.In 2013, the CDC said heart disease was the leading cause of death in the U.S., followed by cancer andrespiratory disease."Top-ranked causes of death as reported by the CDC inform our country's research funding and public health priorities," Dr. Makary said."Right now, cancer and heart disease get a ton of attention, but since medical errors don't appear on the list, the problem doesn't get the funding and attention it deserves," he said.The researchers warn that medical errors are not the same thing as the work of bad doctors. They say medicalmistakes are the result of problems in medical systems and the coordination of care and insurance coverage.The study says its findings should help raise awareness about the problem and support research to prevent medical errors.I’m Mario Ritter._____________________________________________________________ ___Words in This Storyrespiratory – adj. having to do with the system of breathingauthority – n. someone who is an expert in a subjectdiagnostic – adj. relating to identifying sickness or diseaseabsence – n. the lack of somethingunintentionally – adv. done without meaning to, not planned or intentionalstatistics – n. numerical information often about how many or how often something is donedata – n. information。

Our seafood with this special sauce is very good.M: Thank you, but I don’t eat shellfish. I’m allergic to it. Q: Where does this conversation most probably take place?15. W: now one more question if you don’t mind, what position in the company appeals to you most?M: Well, I’d like the position of sales manager if that position is still vacant.Q: What do we learn about the man?16. M: I don’t think I want to live in the dormitory next year.I need more privacy.W: I know what you mean. But check out the cost if renting an apartment first. I won’t be surprised if you change your mind. Q: What does the woman imply?17. M: You’re on the right track. I just think you need to narrow the topic down.W: Yeah, you’re right.

After that, I did careers work in secondary schools like the careers guidance people. Here is in the university. Then I went into local government because I found I was more interested in the administrative side. Then progressed on to universities. So there wasn’t any plan and there was no specific training. There are plenty of training courses in management techniques and committee work which you can attend now. W: But in the first place, you did a French degree.M: In my time, there wasn’t a degree you could do for administration.I think most of the administrators I’ve come across have degrees and all sorts of things.W: Well, I know in my case, I did an English literature degree and I didn’t really expect to end up doing what I am doing now.M: Quite.W: But you are local to Nottingham, actually?

Overnight,Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colderthan Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zeroin Park Rapids, Minnesota, and 45 degrees below zero in Buffalo, North Dakota,according to the National Weather Service. Schools, restaurants, and businessesclosed, and more than l ,000 flights have been canceled.[B] Even the United States Postal Service (USPS) suspended mail deliverytemporarily. "Due to this arctic outbreak and concerns for the safety of USPSemployees," USPS announced Wednesday morning, the Postal Service is suspendingdelivery Jan. 30 in the following 3-digit ZIP Code locations." Twelve regions werelisted as unsafe on Wednesday; on Thursday, eight remained.[C] As global surface temperatures increase, so does the likelihood of extremeweather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and othernatural disasters cost at least $49 billion in the United States. As my colleague VannNewkirk reported, Puerto Rico is still confronting economic and structural destructionand resource scarcity from 2017's Hurricane Maria. Natural disasters can wreck acommunity's infrastructure, disrupting systems for months or years. Some services,however, remind us that life will eventually return, in some form, to normal,[D] Days after the deadly 2017 wildfires in Santa Rosa, California, a dronecaught footage of a USPS worker, Trevor Smith, driving through burned homes in thatfamiliar white van, collecting mail in an affected area. The video is striking: The operation is familiar, but the scene looks like the end of the world. According to RaeAnn Haight, the program manager for the national-preparedness office at USPS,Smith was fulfilling a request made by some of the home owners to pick up any mailthat was left untouched. For Smith, this was just another day on the job. I followedmy route like I normally do," Smith told a reporter. As I'd come across a box thatwas up but with no house, I checked, and there was mail--outgoing mail--in it. Andso we picked those up and carried on.'[E] USPS has sophisticated emergency plans for natural disasters. Across thcountry, 285 emergency-management teams are devoted to crisis control. These teamsare trained annually using a framework known as the three Ps: people, property,product. After mail service stops due to weather, the agency 's top priority is ensuringthat employees are safe. Then it evaluates the health of infrastructure, such as theroads that mail carriers drive on. Finally, it decides when and how tore-openoperations. If the destruction is extreme, mail addressed to the area will get sentelsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming NewOrleans mail to existing mail facilities in Houston. Mail that was already processed inNew Orleans facilities was moved to an upper floor so it would be protected fromwater damage.[F] As soon as it's safe enough to be outside,' couriers start distributingaccumulated mail on the still-accessible routes. USPS urges those without standingaddresses to file change-of- address forms with their new location. After HurricaneKatrina hit in 2005, mail facilities were set up in dozens of other locations across thecountry in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, 493.4 million pieces ofmail -anything from postcards to Social Security checks to medicine. Spokespeoplefrom both USPS and UPS told me all mail is important. But some mail can beextremely sensitive and timely. According to data released in January 2017, 56percent of bills are paid online, which means that just under half of payments still relyon delivery services to be completed.[H] It can be hard to identify which parcels are carrying crucial items such asSocial Security checks, but USPS and UPS try their best to prioritize sensitivematerial. They will coordinate with the Social Security Administration to make surethat Social Security checks reach the right people in a timely fashion. After HurricaneFlorence and Hurricane Michael last fall, USPS worked with state and local electionboards to make sure that absentee ballots were available and received on time.[I] Mail companies are logistics companies, which puts them in a special positionto help when disaster strikes. In a 2011 USPS case study, the agency emphasized itsmassive infrastructure as a unique federal asset" to be called upon in a disaster orterrorist attack. I think we're unique as a federal agency," USPS official MikeSwigart told me, because we're in literally every community in this countryWe' re obligated to deliver to that point on a daily basis.'[J] Private courier companies, which have more dollars to spend, use theirexpertise in logistics to help revitalize damaged areas after a disaster. For more than adecade, FedEx has supported the American Red Cross in its effort to get emergencysupplies to areas affected by disasters, both domestically and internationally. In 2012,the company distributed more than 1,200 MedPacks to Medical Reserve Corps groupsin California, and donated space for 3.1 million pounds of charitable shipping st October, the company pledged $1 million in cash and transportation support forHurricanes Florence and Michael. UPS's charitable arm, the UPS Foundation, usesthe company 's logistics to help disaster-struck areas rebuild. We realize that as acompany with people, trucks, warehouses, we needed to play a larger role," saidEduardo Martinez, the president of the UPS Foundation. The company employs it:trucks and planes to deliver food, medicine, and water. The day before I spoke toMartinez in November, he had been touring the damage fromHurricane Michael inFlorida with the American Red Cross. We have an obligation to make sure ourcommunities are thriving, prosperous," he said.[K] Rebuilding can take a long time, and even then, impressions of the disastermay still remain. Returning to a sense of normalcy can be difficult, but some smallroutines--mail delivery being one of them--may help residents remember that theircommunities are still their communities. When they see that carrier back out on thestreet," Swigart said, that's the first sign to them that life is starting to return tonormal."36. The United States Postal Service has a system to ensure its employees' safety.37. One official says USPS is unique in that it has more direct reach tccommunities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half ofpayments.40. The sight of a mailman on the street is a reassuring sign of life becomingnormal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail servicepoints were set up.42. Postal service in some regions in the U.S. was suspended due to extreme coldweather.43. Private postal companies also support disaster relief efforts by distributingurgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite ofextreme conditions.45. Postal services work hard to identify items that require priority treatment. Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are fourchoices marked A), B), C) and D). You should decide on the best choiceand mark the corresponding letter on Answer Sheet 2 with a single line 'through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Professor Ashok Goel of Georgia Tech developed an artificially intelligentteaching assistant to help handle the enormous number of student questions in theonline class, Knowledge Based Artificial Intelligence. This online course is a corerequirement of Georgia Tech's online Master of Science in Computer Scienceprogram. Professor Goel already had 8 teaching assistants, but that wasn t enough todeal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching support.When students feel isolated or confused and reach out with questions that gounanswered, their motivation to continue begins to fade. Professor Goel decided to dosomething to remedy this situation and his solution was to create a virtual assistantnamed Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill W atson before releasing herto the online forums. At first, the virtual assistant wasnt too great. But Goel and histeam sourced the online discussion forum to find all 40,000 questions that had everbeen asked since the class was launched. Then they began to feed Jill the questionsand answers. After some adjustment and sufficient time, Jill was able to answer thestudents questions correctly 97% of the time. The L virtual assistant became soadvanced and realistic that the students didn t know she was a computer. The students,who were studying artificial intelligence, were interacting with artificial intelligenceand couldn't tell it apart from a real human being. Goel didn 't inform them about Jill'strue identity until April 26. The students were actually very positive about theexperience.The goal of Professor Goel's virtual assistant next year is to take over answering40% of all questions posed by students on the online forum. The name, Jill Watson,will of course, change to something else next semester. Professor Goel has a muchrosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gatesor Steve Wozniak.46.

Thoseare a few of the traits of successful science crowdfunding efforts that emerge from arecent study that examined nearly 400 campaigns. But having a large network andsome promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken offin recent years for everything from making movies to building water-saving gadgets.Scientists have tried to tap Internet donors, too, with mixed success. Some raisedmore than twice their goal, but others have fallen short of reaching more modesttargets.To determine what separates science crowdfunding triumphs from failures, ateam led by science communications scholar Mike Schäfer of the University of Zurichin Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report inPublic Understanding of Science. For one, they use a crowdfunding platform thatspecializes in raising money for science, and not just any kind of project. Althoughsites like Kickstarter take all comers, platforms such as Experiment.com,, and Petridish. org only present scientific projects. For another, theypresent the project with a funny video because good visuals and a sense of humorimproved success. Most of them engage with potential donors since projects thatanswered questions from interested donors and posted lab notes fared better. And theytarget a small amount of money. The projects included in the study raised $4000 onaverage, with 30% of projects receiving less than $ 1000. The more money a projectsought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project's success, most notably,the size of a scientist's personal and professional networks, and how muchresearcher promotes a project on his or her own. Those two factors are by far morecritical than the content on the page. Crowdfunding can be part of researchers effortsto reach the public, and people give because they feel a connection to the person"who is doing the fundraising--not necessarily to the science.11/3151. What do we learn about the scientists trying to raise money online for theirprojects?A) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schafer's research of recent crowdfundingcampaigns?A) To create attractive content for science websites.B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaign?A) The potential benefit to future generations.为B) Its interaction with prospective donors.C) Its originality in addressing financial issues.D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfundingprojects?A) They should be small to be successful.B) They should be based on actual needs.C) They should be assessed with great care.D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaign?A) The ease of access to the content of the webpage.B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part IV Translation (30 minutes) Directions: For this part, you cre allowed 30 minutes to translate a passage from ( 'hinese into English.

2019年12月大学英语四级听力VOA慢速英语(5)The annual Washington Auto Show opened its doors to the general public Tuesday, after a three-day delay caused by a snowstorm that hit the U.S. East Coast. More than 30 world-class auto makers exhibited their latest models, placing special emphasis on connectivity.Coming on the heels of the larger shows in Los Angeles and Detroit, the Washington Auto Show has carved out a niche as the one that emphasizes new technologies, especially those that cause less damage to the environment.But with falling oil prices, the promotion of thriftier hybrid or all-electric vehicles was somewhat muted, shifting the auto show's focus to connectivity and automatization.Automotive engineering professor, Zoran Filipi, says the technology in this Mercedes S-class model shows that we are at the dawn of cars that almost drive themselves.“It has lane-keeping ability, it has advanced radar-based system to keep the vehicle’s speed also in sync with other vehicles and this can completely alleviate your effort, driving effort, in stop-and-go situations too, and finally the collision avoidance," said Filipi.Very soon we will see these technologies trickling-down to more affordable models as car makers work to develop fully autonomous-driving cars.In the meantime, says Filipi, fuel efficiency has improved 20 percent over the last 10 years.“This has mostly been achieved with advanced engine technologies – direct injection, turbo-charging, coupled to very modern transmissions, eight, nine, ten speeds that keep the engine running in the best possible region," he said.Almost all new models have built-in display screens that connect the vehicle to the driver’s smartphone and the Internet, helping in navigation, taking voice commands, and sending and receiving messages.“Therefore you can use all the applications you are used to, everything that is tailored to your needs in your car and it’s very seamless," said Filipi.Larger manufacturers, such as Toyota, say their all-electric fuel-cell cars are ready for the market and the only obstacle is the lack of charging stations.Others promote their hybrid gas-electric models, saying that the number of charging stations is constantly rising while the price of home chargers is dropping.South Korean carmaker Hyundai even offers a lifetime warranty for the battery in its top-of-the-line model, hoping to make the hybrid car more attractive to customers.。

LOS ANGELES—
After 25 years of marriage and five children, Maria Elena and Rene Burgos of Los Angeles have become a unified force on many things, including decisions on Election Day.
“Mostly we discuss and we agree and then we usually mark our ballots together, and we start marking together, and we decide together. We try to support each other,” said Maria Elena Burgos.
“We discuss it with the family, too, now that we have the gr ownup kids,” Rene Burgos said.
All born in the United States, four of the Burgoses' children are old enough to vote in the 2016 presidential election. It will be 18-year-old Monica Burgos’ first presidential election. She said it’s the issues, including immigration, that will help her pick the best candidate.
“Immigration is serious because people are always crossing the border. They’re always trying to come to America for a better life, and that’s what my parents did,” she said.
Maria Elena Burgos’ mother was American, which allowed her to get U.S. citizenship. Rene Burgos escaped the civil war in El Salvador and arrived in the U.S. as an undocumented immigrant. Under the Regan administration, he received amnesty and ultimately citizenship.
“So after I became a citizen and I was able to exercise [my right to vote], I said I have the duty to do it and I was really happy to be able to participate," he said. "I think coming from another country to the United States and seeing that you can participat e, it is a great opportunity.”
“When you come from a country where sometimes you do
not have the rights or the voice, having that opportunity
here makes a difference,” said Maria Elena Burgos.
That commitment was passed down to their children, including Stephen, 22.
“Our parents always encourage us to vote, to be able to be the voice for change,” he said.
Latino vote
The belief that a vote still matters is what motivates many naturalized immigrants and their children to try and be the most en gaged Latinos in American politics. They don’t
take the vote for granted, said Arturo Vargas, executive director of the National Association of Latino Elected and Appointed Officials' Educational Fund.
“The immigrant voter, the naturalized citizen and h is
or her children, the children of immigrants are the most engaged in American politics," Vargas said. "They are
following politics very, very closely. Those that we need to bring into the process are those that have been here for four, five, six generations: Mexican-Americans that speak English only because that’s the only language they know. [It’s] the same thing with Puerto Ricans and Latinos of other national
origin groups who, unfortunately, many of them have lost
faith in the American political syste m.”
For many Latinos, the issue of immigration has become a litmus test for a candidate.
“How a candidate talks about immigrants is symbolic of how that candidate then appears towards Latinos," Vargas said. "So if a candidate is bashing immigrants, Latinos hear that
as bashing Latinos. So how a candidate talks about
immigration is even more important than what the candidate
has to say about immigration policy.”
While a large number of Latinos identify themselves as Democrats, Vargas said the fastest-growing party affiliation
of Latinos is either “declined to state” or “independent.”
Choosing a candidate
Members of the Burgos family have not decided which presidential candidate they will vote for, but that person needs to share their values, said Martin Burgos, 20.
“Since we’re practicing Roman Catholics, we’ll talk about abortion especially. That’s one of the major topics,” he said.
Maria Elena Burgos said she knows there is no perfect candidate.
“We have to just balance and see which one is the least evil and which is the one that we would be more happy with, even though it’s not perfect. No person, no party, no
decision will be 100 percent perfect,” she said.。
