正确答案: B

Airline apps have immensely transformed travelers' digital lives.

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：主旨题。文章主要讲述了航空公司的应用程序给人们带来的种种便捷，最后一段第一句“Clearly,mobile apps and social media have transformed our digital lives.”总结了前文内容，后面的话都是对这句话的展开说明。A.C两项文章均未提及。D项内容为文章中的细节信息，并不能概括全文意思。故本题选B。

[单选题]在原型内化阶段，对学生言语培养的重点应放在( )上。

考查言语的动作效应

解析：言语在原型内化阶段的作用在于巩固形成中的动作形象，并使动作表象得以进一步概括，从而向概念性动作映像转化。这时言语已转变成为动作的体现者，成为加工动作对象的工具。所以，这时培养的重点应放在考查言语的动作效应上。

[单选题]短时记忆保持的时间大约是2秒到5秒。( )A.正确B.错误

解析：短时记忆(short-termmemory)简称STM，也称工作记忆，是信息加工系统的核心。短时记忆的容量又称为记忆广度，指彼此无关事物短暂呈现后能记住的最大数量。人的短时记忆广度为7+2个组块。而短时记忆的保持时间在无复述的情况下只有5～20秒，最长也不超过1分钟。

[多选题]心理学实验和相关研究证明，对理解的知识有复习的学生较无复习的学生保持效果好。如果没有对所学内容进行巩固复习，则保持的较少，遗忘的较多。即使只有一次复习，其保持的效果也会提高。复习是防止知识遗忘、巩固知识的基本途径，是提高知识保持效果的重要条件。但复习并不等于机械重复，保持的效果也不取决于复习次数的多少或所花费时间的长短，而取决于复习活动的合理组织。为了促进知识的保持，避免知识的遗忘，必须注意合理地组织复习。那么，如何根据遗忘规律，正确地组织复习以促进知识的保持呢？
