• 共用题干Smartphone Customers up for Grab
  About 10 years ago I met an advertising executive in New York who explained the difficulty of advertising a new brand of deodorant（除臭剂）to consumers."Most people never change their deodorant,"I remember him saying."They pick one brand when they are young,and stick with it for a long,long time.If it works,why switch?"
  The same theory can be applied_______(46)Once they have picked a type of phone,whether it's Apple iOS,Google Android or something else,it's difficult,and often expensive,to switch? Consumers become comfortable with the interface and design of the phone and the apps they have purchased on that platform._______(47)
  That is why the race to pull in smartphone buyers is going to be especially severe over the next 18 to 24 months._______(48)there are still hundreds of millions of mobile phone owners around the world who have yet to move from a standard mobile or feature phone to its smarter,more intelligent big brother:the smartphone.
  Yet the change is happening at a much quicker pace than technology analysts and companies originally theorized.A report issued this week by Nielsen,the market research firm,found that among Americans_______(49)55 percent opted for a smartphone.This is up from 34 percent a year ago.
  At this point,who will lead that market is not up for debate.Android has been growing at a pace no one could have imagined,even Google.The company said this week that it now activates more than 500,000 Android devices each day.
  Mr. llamas said Apple,which changed the smartphone game in 2007 when it introduced the iPhone,potentially has a ceiling with consumers as its mobile phone is often more expensive than those of its competitors.
  Although millions of customers flock to Apple products for their beauty,simplicity and powerful brand,many can't afford a new iPhone.This could change_______(50)as some analysts expect. "Right now the iPhone only comes in one flavor;it's not like other Apple products like the iPod where there are several different sizes,shapes and prices,"Mr. Llamas said. ________（50）A:Although it may seem that everyone owns a smartphone these days,B:if Apple offers a less expensive model of the iPhone later this year,C:to customers who are making the switch to smartphones today.D:who purchased a new mobile phone in the last three monthsE:The smartphone race is still raging.F:If it works,why switch?
