题目：请阅读 Passage 1,完成1~5小题。 Passage 1 When it comes to airline travel,perhaps nothing has revolutionized the passenger experience more than airline apps.IndeeD.they're becoming so ubiquitous that more than 50 percent of U.S travelers have at least one airline app installed on their smart device,according to travel industry research firm Phocuswright.Maybe that's because apps make travel easier,and often are more functional than a kiosk or even an airline'sown website.Passengers report that they're often more quickly informed of a flight cancellation or gate change than an airline employee.Not all airline apps are created equal, 　　but in general you can use an app to check in for a flight,change seats,and request and pay for an upgrade.Road warriors in particular appreciate mobile boarding passes and the ability to track their flights.Many airlines now offer free onboard streaming entertainment via apps.The Delta Air Lines app even allows users to track their bags,from check-in to carousel,while the Air France app lets passengers download magazines and newspapers from the airline's library 30 hours prior to departure. But what if you are traveling extensively on more than one airline? Global airline alliances have their own apps that allow you to view flights for all member airlines and their affiliates,including code share flights.In general,you can find flight schedules for all member airlines and track member airline flights.Airport information is available,as are details about local weather at the destination.Where's the nearest airport lounge? The app will locate it for you. The SkyTeam airline alliance app goes a step further by letting its SkyPriority members (SkyTeam Elite Plus members and customers with first and business-class tickets) find out exactly which SkyPriority services-including priority check in and baggage drop off,as well as access to priority security lanes and boarding lanes-are available at individual airports. You'll find that some alliance app features are available through multiple channels of communication.For example,SkyTeam members have formed their own online community by sharing traveler tricks and airport tips accessible through a variety of channels,including the app,SkyTeam's website,Facebook page and a dedicated tips site.SkyTeam's YouTube page features travel tips from regional celebrities. Just as airlines seem to have conquered social mediA.another method of communicating with travelers has just arrived.KLM Royal Dutch Airlines is the first carrier to sign up for Facebook's Messenger chat app.KLM flyers can automatically receive itineraries,flight updates,checkin notifications,boarding passes and rebook flights and communicate with customer service,all from Facebook Messenger.Messenger for Business was launched so that customers-in this case,passengers-can transact business over the messaging app in a single communication thread.Roughly 80 percent of passengers on planes traveling within the U.S.have the Messenger app installed on their smartphones,according to Facebook. 　　Clearly,mobile apps and social media have transformed our digital lives.Airlines favor apps and other technologies because they get customers out of airport lines and off phone lines.Through their smart devices,travelers now have <u>untethered</u> access to travel information.A few quick taps can supply individuals with information never dreamed possible even a decade ago.And with more people using smartphones as their primary computing device,and as more people own cell phones globally,people expect technology-driven methods of communication and convenience to accelerate.Whether you're high-tech or not,you must admit that having immediate access to the information you need sure beats getting a busy signal on a toll-free phone line.

解析：词汇题。画线单词所在句为“Airlines favor apps and other technologies because they get customers out of airport lines and off phone lines.Through their smart devices,travelers now have untethered access to travel information.”，这句话是说航空公司喜欢应用程序和其他技术是因为他们能够让客户摆脱机场线和电话线；通过他们的智能设备，旅客们现在可以_______获取旅行信息。前面作者强调的是应用程序及其他技术使人们摆脱了对机场线和电话线的依赖，也就是说打破了这种限制，因此这里的untethered应该是无限制的意思。故本题选A。

[单选题]请阅读 Passage 2,完成 1~5小题。 　　Passage 2 　　When American-bom actor Michael Pena was a year old.his parents were deported.They had illegally walked across the U.S.border from Mexico and when they were caught by immigration authorities,they sent Pena and his brother to stay with relatives in the U.S."It was quite a bit of a gamble for my parents," says Pena."but they came back a year later." Pena's father,who had been a farmer in Mexico,got a job at a button factory in Chicago anD.eventually,a green card.Pena stayed in Chicago until,at 19,he fled to Los Angeles to pursue his acting dreams. 　　This family history makes Pena's latest role especially personal.In Cesar Chavez,Pena plays the labor leader as he struggles to organize immigrant California farm workers in the 1960s.To pressure growers to improve working conditions and wages,Chavez led a national boycott of table grapes that lasted from 1965 to 1970 and is recorded in the film.Chavez,like Pena.was the American-born son of Mexican farmers who immigrated to the U.S."He understands this duality,the feeling of being born in a place but having a very big idea of where your heritage comes from," says the film director,Diego Luna."This thing of having to go to school and learn in English and then go home to speak Spanish with your parents." 　　As immigration policy is hotly debated on Capitol Hill this year,Luna and others who were involved with Cesar Chavez are hoping the movie will spark new support for reform and inspire American Latinos to get involved."The message Chavez left was that change couldn't happen without the masses being a part of their own change," says Ferrera.a first generation Honduran American who plays the union leader's wife Helen.Rosario Dawson,who co-founded the advocacy group Voto Latino,plays Chavez ally and labor leader Dolores Huerta. 　　Immigrant-rights issues in the U.S.have evolved substantially in the years since Chavez founded the United Farm Workers (UFW).Undocumented workers now make up a far larger share of the agricultural workforce in Califomia than they did in the 1960s,according to Miriam Pawel,author of The Crusades of Cesar Chavez,published the next month.Chavez was vehemently against illegal immigration,believing it made strikes difficult to execute and weakened the union.FIe initiated a program in the mid-1970s to locate undocumented farm workers and report them to immigration officials,Pawel writes.And despite his early victories,Chavez's UFW union represents just a small part ofthose working on California farms today. 　　"Chavez's legacy is not in the field.which is sad." says Pawel.Still,she says,his organizing strategies,featured extensively in Cesar Chavez,have been adopted by other activists,including those leading the modern immigrant-rights movement.Chavez's most important contribution may have been humanizing the Latino population for the American publiC.Farm laborers,many of whom barely spoke English,traveled across the country during the grape boycott,standing outside grocery stores to persuade housewives not to buy grapes and to spread the word about their plight."They gave the boycott this very human face," says Pawel. 　　"It was families talking to other families," says Luna."It's about the power we have just by being who we are."

What did the film-makers want to achieve through the movie Cesar Chavez?

To stir immigration debates with a biopic.
