共用题干Mobile Phones:Change Our LifeIn the case of mobile phones,change is everything. Recent research indicates that the mobile phone is changing not only our culture,but our very bodies as well.First,Let's talk about culture.The difference between the mobile phone and its parent一the fixed-line phone,is that a mobile phone corresponds to a person,while a landline goes to a place.If you call my mobile,you get me.If you call my fixed-line phone,you get whoever answers it.This has several implications.The most common one,however,and perhaps the thing that has changed our culture forever,is the"meeting"influence.People no longer need to make firm plans about when and where to meet.Twenty years ago,a Friday night would need to be arranged in advance.You needed enough time to allow everyone to get from their place of work to the first meeting place.Now,however,a night out can be arranged on the run.It is no longer"see you there at 8", but"text me around 8 and we'll see where we all are".Texting changes people as well.In their paper,"Insights into the Social and Psychological Effects of SMS Text Messaging",two British researchers distinguished between two types of mobile phone users:the"talkers"and the"texters”一those who prefer voice to text message and those who prefer text message to voice.They found that the mobile phone's individuality and privacy gave texters the ability to express a whole new outer personality.Texters were likely to report that their family would be surprised if they were to read their texts.This suggests that texting allowed texters to present a self-image that differed from the one familiar to those who knew them well.Another scientist wrote of the changes that mobiles have brought to body language.There are two kinds that people use while speaking on the phone.There is the"speakeasy":the head is held high,in a self-confident way,chatting away.And there is the"spacemaker":these people focus on themselves and keep out other people.Who can blame them?Phone meetings get cancelled or reformed and camera-phones intrude on people's privacy. So,it is understandable if your mobile makes you nervous.But perhaps you needn't worry so much.After all,it is good to talk.When arranging a night out,people may text each other.A:Right B:Wrong C:Not mentioned

资料：Virgin America helped Airbus pip Boeing at the post to retain its crown as the world’s largest commercial plane maker.Airbus trailed its arch-rival Boeing in number of orders for most of 2010 but moved ahead after a flurry of sales at the end of the year. At the end of December, Virgin America, Richard Branson’s upstart US airline, ordered 30 of the updated version of Airbus’s A320 model. Airbus has promised the A320 with the new engine option will cut fuel consumption and carbon emissions by 15% compared with the existing models, figures disputed by Boeing and some analysts. The $5.1nd（￡ 3.2nd） contract was the first order for the updated airplanes.The Virgin deal capped a year when Airbus took orders for 644 airplanes worth $84nd at list price. Boeing won 625 gross orders with a list price of $70nd. It was held back by delays to its 787 Dreamliner.Both Airbus and Boeing are recovering strongly from an industry recession that saw combined demand for their planes fall by more than two-thirds in 2009. White there were still dozens of plane cancellations in 2010, and both firms have struggled with delays, Airbus secured more than twice the number of airplane orders in 2010 that it had anticipated.Tom Enders, chief executive, said:”2010 has been better than we expected. We will look at 2011 more optimistically. Growth, especially in aviation, is back, and this is largely due to emerging markets. Asia, the Middle East, that’s certainly been the focus.”Last week Airbus announced a $16nd deal with Indigo for 180 airplanes, the largest single order for aircraft in commercial aviation history. The order includes 30 of Airbus’s original A320 single-aisle jets and 150 with Airbus’s new engine-option A320s.Airbus delivered more planes than its US rival for the eighth consecutive year. Its total of 510 deliveries, up from 498 in 2009, topped the 500 mark for the first time at Airbus. Last year the company sold its 10,000th plane in its 40-year history Boeing deliveries fell by 4% to 462 airplanes from 481.John Leahy, Airbus sales chief, said: “There figures show the economy is improving. We have dodged the bullet on a double-dip recession. Aviation is growing again because of Asia, low-cost carriers emerging markets. The only negative on the horizon is the fuel price.”Which of the following is TRUE according to the article?A.IndiGo’s order for Airbus’s new engine-option A320s was the first firm order for the updated airplanes.B.Airbus delivered more planes than Boeing in 2006.C.2009 saw demand for Boeing’s planes fall but not Airbus’s.D.Airbus was able to stay ahead of Boeing in number of orders throughout the year 2010.
资料：The business announced that revenues had grown by 10.2 percent year-on-year to RMB 18.264 billion （$2.748billion）. However, profit fell to RMB 2.866 billion （$431.3 billion）, a 17.4 percent decrease from the same period in 2015.Robbin li, Chairman and CEO of Baidu, said:"The challenges Baidu faced in the second quarter served as a healthy reminder to stay focused on the key drivers of growth, sustainability and leadership; delivering the best user experience and staying at the forefront of technology. As we enter the next chapter of the Internet, led by artificial intelligence, Baidu has never been better positioned to serve our users and work with our customers and partners, and change the world through technology." The business has been rocked by a series of high profits issues with its advertising business this year. Baidu was called out for its practices around selling access to forums early this year. Not long after it also agreed to overhaul the way it delivers its search ads, including the volume of ads served, after a huge public backlash saw Baidu taking some of the blame for the death of a student who died after taking experimental cancer treatment that be found from a search ad.The overhaul has been welcomed by the industry which believes will create a better experience, particularly on mobile.The business said the revenue from mobile was growing as it represented 63 percent of total revenues for the second quarter of 2016, compared to 50 percent in 2015. According to Baidu, mobile search monthly active users were 667 million for the month of June 2016, an increase of 6 per cent year-over-year. It said users of its mobile maps service grew by 13 percent and the number of activated Baidu Wallet accounts reached 80 million, representing a 131 percent year-on-year growth.What is the author's attitude towards Baidu?A.SubjectiveB.CriticalC.UnbiasedD.Supportive

资料：Singapore Airlines plans to introduce inflight mobile phone and internet access in May this year,beginning with its flagship Airbus A380 fleet.Several pricing models are believed to be under consideration,beginning with a low-cost package suitable for WE—service such as Google Gmail,Yahoo and Hotmail as well as a 30MB allowance for around SGD$25 （that's $20 Russia and US,and ￡20 and ￡ 14）.The airline is polling selected members of its KrisFlyer frequent flyer loyalty program to participate in an online survey about your attitudes towards inflight mobile and internet services,which we are planning to introduce from May 2011 according to the email invitation.The survey asks travellers for their opinions on pricing packages such as SGD$25 for 30MB,as well as if mobile phone cells and SMS messages should be permitted.Should passagers be allowed to make and take calls at 30000 feet they'll pay plenty for the privilege, with calls being charged at international roaming rates.As it's up to each country to decide what those rates are-and with Singapore Airlines effectively being its own country in terms of providing a fully controlled and self-contained telecoms system on board each plane-those rates could literally be sky high.SQ's inflight internet and mobile service, which may carry the KrisNet brand in keeping with the KrisWorld inflight entertainment system, is expected to debut on the Airbus A380 before being installed onto the airline's A340-500 and Boeing 777-300ER aircraft.Passagers will be able to access the internet on any device from a smart phone to a tablet or laptop, as Singapore Airlines will support connections through both Wifi wireless networking （using a series of low-hotpots located throughout the plane） and 3G（via tiny pico-cell stations）.It will employ the pepular OnAir technology, jointly developed by IT company SITA and Airbus,and currently used by over 20 airlines（including Air New Zealand's currenttrial of in-flight internet） which feeds the Wifi and 3G signals through to Inmarsat's SwiftBroadband satellite network.Which of the following may be the best title for the passage?A.Singapore Airlines to charge high international roaming ratesB.Singapore Airlines to offer different pricing models for inflight mobile and Internet servicesC.Singapore Airlines to unveil sky high netD.Singapore Airlines to conduct online survey

资料：Virgin America helped Airbus pip Boeing at the post to retain its crown as the world’s largest commercial plane maker.Airbus trailed its arch-rival Boeing in number of orders for most of 2010 but moved ahead after a flurry of sales at the end of the year. At the end of December, Virgin America, Richard Branson’s upstart US airline, ordered 30 of the updated version of Airbus’s A320 model. Airbus has promised the A320 with the new engine option will cut fuel consumption and carbon emissions by 15% compared with the existing models, figures disputed by Boeing and some analysts. The $5.1nd（￡ 3.2nd） contract was the first order for the updated airplanes.The Virgin deal capped a year when Airbus took orders for 644 airplanes worth $84nd at list price. Boeing won 625 gross orders with a list price of $70nd. It was held back by delays to its 787 Dreamliner.Both Airbus and Boeing are recovering strongly from an industry recession that saw combined demand for their planes fall by more than two-thirds in 2009. White there were still dozens of plane cancellations in 2010, and both firms have struggled with delays, Airbus secured more than twice the number of airplane orders in 2010 that it had anticipated.Tom Enders, chief executive, said:”2010 has been better than we expected. We will look at 2011 more optimistically. Growth, especially in aviation, is back, and this is largely due to emerging markets. Asia, the Middle East, that’s certainly been the focus.”Last week Airbus announced a $16nd deal with Indigo for 180 airplanes, the largest single order for aircraft in commercial aviation history. The order includes 30 of Airbus’s original A320 single-aisle jets and 150 with Airbus’s new engine-option A320s.Airbus delivered more planes than its US rival for the eighth consecutive year. Its total of 510 deliveries, up from 498 in 2009, topped the 500 mark for the first time at Airbus. Last year the company sold its 10,000th plane in its 40-year history Boeing deliveries fell by 4% to 462 airplanes from 481.John Leahy, Airbus sales chief, said: “There figures show the economy is improving. We have dodged the bullet on a double-dip recession. Aviation is growing again because of Asia, low-cost carriers emerging markets. The only negative on the horizon is the fuel price.”According to Airbus, the updated version of its A320 model is different from the original model in that________.A.it has multiple options when it comes to its engineB.it is a single-aisle jetC.it is more fuel-efficient and environmental-friendlyD.it has a more powerful engine
资料：Singapore Airlines plans to introduce inflight mobile phone and internet access in May this year,beginning with its flagship Airbus A380 fleet.Several pricing models are believed to be under consideration,beginning with a low-cost package suitable for WE—service such as Google Gmail,Yahoo and Hotmail as well as a 30MB allowance for around SGD$25 （that's $20 Russia and US,and ￡20 and ￡ 14）.The airline is polling selected members of its KrisFlyer frequent flyer loyalty program to participate in an online survey about your attitudes towards inflight mobile and internet services,which we are planning to introduce from May 2011 according to the email invitation.The survey asks travellers for their opinions on pricing packages such as SGD$25 for 30MB,as well as if mobile phone cells and SMS messages should be permitted.Should passagers be allowed to make and take calls at 30000 feet they'll pay plenty for the privilege, with calls being charged at international roaming rates.As it's up to each country to decide what those rates are-and with Singapore Airlines effectively being its own country in terms of providing a fully controlled and self-contained telecoms system on board each plane-those rates could literally be sky high.SQ's inflight internet and mobile service, which may carry the KrisNet brand in keeping with the KrisWorld inflight entertainment system, is expected to debut on the Airbus A380 before being installed onto the airline's A340-500 and Boeing 777-300ER aircraft.Passagers will be able to access the internet on any device from a smart phone to a tablet or laptop, as Singapore Airlines will support connections through both Wifi wireless networking （using a series of low-hotpots located throughout the plane） and 3G（via tiny pico-cell stations）.It will employ the pepular OnAir technology, jointly developed by IT company SITA and Airbus,and currently used by over 20 airlines（including Air New Zealand's currenttrial of in-flight internet） which feeds the Wifi and 3G signals through to Inmarsat's SwiftBroadband satellite network.From the passage,we know that__.A.Singapore Airlines' online survey is to be carried out among its registered members.B.Airbus A380 will be the first aircraft to be equipped with inflight internet and mobile service.C.Singapore Airlines' inflight internet access will be limited to some specific devices.D.Singapore Airlines' will be the first to introduce inflight mobile phone and internet access.
