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: Should 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 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 .Microsoft's Internet Explorer and Apple's Safari both offer DNT ;Google's Chrome is due to do so this year. 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 advertisers 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 Microsoft’s default, some may ignore a DNT signal and press on anyway.
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 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, bloggde:"we believe consumers should have more control." Could it really be that simple?

Up 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 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 millions of years - so why shouldn't 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 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 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 today's technology, and its social consequences, is dazzlingly complicated, and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage. That's one reason why we have launched Arc, a new publication dedicated to the near future.
But take a longer view and there is a surprising amount that we can say with considerable assurance. As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves.
This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad. To be sure, the future is not all rosy. But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come.
31. Our vision of the future used to be inspired by
[A] our desire for lives of fulfillment
[B] our faith in science and technology
[C] our awareness of potential risks
[D] our belief in equal opportunity

On a five to three vote,the Supreme Court knocked out much of Arizona's immigration law Monday-a modest policy victory for the Obama Aministration.But on the more important matter of the Constitution,the decision was an 8-0 defeat for the federal government and the states.
An arizona.United States,the majority overturned three of the four contested provisions of Arizona's controversial plan to have state and local police enfour federal immigrations law.The Constitutional principles that Washington alone has the power to "establish a uniform Rule of Anturalization" and that federal laws precede state laws are noncontroversial.Arizona had attempted to fashion state police that ran to the existing federal ones.
Justice Anthony Kennedy,joined by Chief Justice John Roberts and the Court's liberals,ruled that the state flew too close to the federal sun .On the overturned provisions the majority held the congress had deliberately "occupied the field " and Arizona had thus intruded on the federal's privileged powers
However,the Justices said that Arizona police would be allowed to verify the legal status of people who come in contact with law enforcement.That’s because Congress has always envisioned joint federal-state immigration enforcement and explicitly encourages state officers to share information and cooperate with federal colleagues.
Two of the three objecting Justice-Samuel Alito and Clarence Thomas-agreed with this Constitutional logic but disagreed about which Arizona rules conflicted with the federal statute. The only major objection came from Justice Antonin Scalia,who offered an even more robust defense of state privileges going back to the alien and Sedition Acts.
The 8-0 objection to President Obama tures on what Justice Samuel Alito describes in his objection as “a shocking assertion assertion of federal executive power”. The White House argued tha Arizona’s laws conflicted with its enforcement priorities, even if state laws complied with federal statutes to the letter. In effect, the White House claimed that it could invalidate any otherwise legitimate state law that it disagrees with.
Some powers do belong exclusively to the federal government,and control of citizenship and the borders is among them. But if Congress wanted to prevent states from using their own resources to check immigration status,it could.It could.It never did so.The administration was in essence asserting that because it didn't want to carry out Congress's immigration wishes,no state should be allowed to do so either.Every Justice rightly rejected this remarkable claim.
36. Three provisions of Arizona’s plan were overturned because they
[A] deprived the federal police of Constitutional powers.
[B] disturbed the power balance between different states.
[C] overstepped the authority of federal immigration law.
[D] contradicted both the federal and state policies.
37. On which of the following did the Justices agree,according to Paragraph4?
[A] Federal officers’ duty to withhold immigrants’information.
[B] States’ independence from federal immigration law.
[C] States’ legitimate role in immigration enforcement.
[D] Congress’s intervention in immigration enforcement.
38. It can be inferred from Paragraph 5 that the Alien and Sedition Acts
[A] violated the Constitution.
[B] undermined the states’ interests.
[C] supported the federal statute.
[D] stood in favor of the states.
39. The White House claims that its power of enforcement
[A] outweighs that held by the states.
[B] is dependent on the states’ support.
[C] is established by federal statutes.
[D] rarely goes against state laws.
40. What can be learned from the last paragraph?

[B] Justices intended to check the power of the Administrstion.
[C] Justices wanted to strengthen its coordination with Congress.
[D] The Administration is dominant over immigration issues.
