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, companie
2、s 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: Should advertisers assume that people are happy to be tracked and sent behavioural ads? Or should they have explicit permission?In
3、December 2010 Americas Federal Trade Cornmission (FTC) proposed adding a “do not track “(DNT) option to internet browsers ,so that users could tell adwertisers that they did not want to be followed .Microsofts Internet Explorer and Apples Safari both offer DNT ;Googles Chrome is due to do so this ye
4、ar. In February the FTC and Digltal Adwertising Alliance (DAA) agreed that the industry would get cracking on responging 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 a
5、dvertisers will respond. Geting 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 Microsofts default, some may ignore a DNT signal and press on anywa
6、y.Also unclear is why Microsoft has gone it alone. Atter 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 s
7、elling point for windows 8-though the firm has compared some of its other products favourably with Googles on that count before. Brendon Lynch, Microsofts chief privacy officer, bloggde:“we believe consumers should have more control.“ Could it really be that simple?26. It is suggested in paragraph 1

11、ismText 3Up until a few decades ago, our visions of the future were largely - though by no means uniformly - glowingly positive. Science and technology would cure all the ills of humanity, leading to lives of fulfillment and opportunity for all.Now utopia has grown unfashionable, as we have gained a
12、 deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change. You might even be tempted to assume that humanity has little future to look forward to.But such gloominess is misplaced. The fossil record shows that many species have endured for mill
13、ions of years - so why shouldnt we? Take a broader look at our species place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years . Look up Homo sapiens in the “Red List“ of threatened species of the International Union
14、for the Conversation of Nature (IUCN) ,and you will read: “Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline.“So what does our deep future hold? A growing number of researchers
15、 and organisations are now thinking seriously about that question. For example, the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence .Perhaps willfully , it may be easier to think about such lengthy timescales than about the more immediate future. The potential evolution of todays technology, and its social consequences, is dazzlingly complicated, and its perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage. Thats one reason why we h
