An old saying has it that half of all advertising budgets are wasted-the trouble is,no one-|||-knows which half.In the internet age, at least in theory, this fraction can be much reduced.By-|||-watching what people search for,click on and say online,companies can aim "behavioural"ads at-|||-those most likely to buy.-|||-In the past couple of weeks a quarrel has illustrated the value to advertisers of such fine--|||-grained information: Shou advertisers assume that people are happy to be tracked and sent-|||-behavioural ads? Or should they have explicit permission?-|||-In December 2010 America`s Federal Trade Commission(FTC)proposed adding a "do not-|||-track"(DNT)option to internet browsers,so that users could tell advertisers that they did not-|||-want to be followed.Microsoft`s Inte Explorer and Apple `s Safari both offer DNT;Google`s-|||-Chrome is due to do so this year.In February the FTC and Digital Advertising Alliance (DAA)-|||-agreed that the industry would get cracking on responding to DNT requests.-|||-On May 31st Microsoft set off the row:It said that Internet Explorer 10,the version due to-|||-appear Windows 8,would have DNT as a default.-|||-It is not yet clear how advertisers will respond.Getting a DNT signal does not oblige anyone-|||-to stop tracking,although some companies have promised to do so. Unable to tell whether-|||-someone really objects to behavioural ads or whether they are sticking with Microsoft`s default,-|||-some may ignore a DNT signal and press on anyway.-|||-Also unclear is why Microsoft has gone it alone.After all, it has an ad business too,which-|||-it says will comply with DNT requests,though it is still working out how.If it is trying to upset-|||-Google,which relies almost wholly on default will become the norm.DNT does not seem an-|||-obviously huge selling point for Windows 8-though the firm has compared some of its other-|||-products favourably with Google`s on that count before.Brendon Lynch,Microsoft`s chief privacy-|||-officer,blogged:"We believe consumers should have more control "Could it really be that-|||-simple?-|||-(Retrieved from http:wwwhenglish.comkaoyanzhen-|||-(1)It is suggested in paragraph 1 that "behavioural"ads help advertisers to __ _。-|||-A.ease competition among themselves-|||-B.lower their operational costs-|||-C.avoid complaints from consumers-|||-D.provide better online services-|||-(2)"The industry"(Line 5,Para.3)refers to __ .-|||-A.online advertisers B.e-commerce conductors-|||-C.digital information analysis D.internet browser developers-|||-(3)Bob Liodice holds that setting DNT as a default __ ---|||-A.many cut the number of junk ads-|||-B.fails to affect the ad industry-|||-C.will not benefit consumers-|||-D.goes against human nature-|||-(4)Which of the following is true according to Para.6?-|||-A.DNT may not serve its intended purpose.-|||-B.Advertisers are willing to implement DNT.-|||-C.DNT is losing its popularity among consumers-|||-D.Advertisers are obliged to offer behavioural ads.-|||-(5)The author`s attitude towards what Brendon Lynch said in his blog is one of __ --|||-A.indulgence B.understanding-|||-C.appreciation D.skepticism
