For the first time on record,the number of advertising-specific jobs in the U.S.is declining in the middle of an economic expansion,according to government data.What's going on?It's certainly not a case of fewer advertisements.The typical American has gone from seeing about 500 ads each day in the 1970s to about 5,000 today,according to a common industry statistic.That is one corporate message for roughly every 10 seconds of waking life.Instead,the mysterious decline can be explained by two developments.First,there are Facebook and Google.They are the largest advertising companies in the world-and,quite likely,the largest in the history of the world.Last year,90 percent of the growth of the digital-advertising business went to just these two firms.Facebook and Google are so profitable because they use their enormous scale and data to deliver targeted advertising at a low cost.This has forced the world's large advertising firms to preserve their profitability through a series of mergers,accompanied by jobs cut.s in the name of efficiency.The emergence of an advertising duopoly has coincided with the rise of"programmatic advertising,"a term that essentially means"companies using algorithms to buy and place ads in those little boxes all over the internet."As any Macl Men fan might intuit,advertising has long been a relationship-driven business,in which multimillion-dollar contracts are hammered out over one-on-one meetings,countless lunches,and even more-countless drinks.With programmatic technology,however,companies can buy access to specific audiences across several publishing platforms at once,bypassing the work of building relationships with each one.That process produces more ads and requires fewer people-or,at least,fewer traditional advertising jobs and more technical jobs.Second,there is the merging of the advertising and entertainment businesses.As smartphone screens have edged out TV as the most important real estate for media,companies have invested more in"branded content"-corporate-sponsored media,such as an article or video,that resembles traditional entertainment more than it does traditional advertising.Some of the most prominent names in journalism,such as The New York Times,BuzzFeed,Vice,and The Atlantic,are owned by companies that have launched their own branded-content shops,which operate as stand-alone divisions.As many media companies have tried to become more like advertising companies,the value of the average"creative-account win,"an ad-industry term for a new contract,has declined,falling by about 40 percent between 2016 and 2017.So there are two major themes of the decline of advertising jobs,one that has to do with the companies that now create them and one that has to do with the way brands prefer to market themselves nowadays.In short,the future of the advertising business is being moved to technology companies managing ad networks and media companies making branded content-that is,away from the ad agencies.With programmatic technology,Facebook and Google couldA.produce more ads and create more advertising jobs.B.merge a series of large advertising companies.C.deliver advertising to specific audiences at a low cost.D.build relationships with publishing platforms one by one.

共用题干第三篇Ways to Create Colors in a PhotographThere are two ways to create colors in a photograph.One method called additive,starts with three basic colors and adds them together to produce some other color. The second method,called subtractive,starts with white light(a mixture of all colors in the spectrum)and,by taking away some or all other colors,leaves the one desired.In the additive method,separate colored lights combine to produce various other colors.The three additive primary colors are green,red and blue(each providing about one-third of the wavelengths in the total spectrum).Mixed in varying proportions,they can produce all colors.Green and red light mix to produce yellow,red and blue light mix to produce magenta(a purplish pink);green and blue mix to produce cyan(a bluish green).When equal parts of all three of these primary-colored beams of light overlap（重叠）,the mixture appears white to the eye.In the subtractive process colors are produced when dye（染料）absorbs some wavelengths and so passes on only part of the spectrum.The subtractive primaries are cyan,magenta and yellow; these primaries or dyes absorb red,green and blue wavelengths respectively,thus subtracting them from white light. These dye colors are the complementary colors to the three additive primaries of red,green and blue.Properly combined,the subtractive primaries can absorb all colors of light, producing black.But,mixed in varying proportions,they too can produce any color in the spectrum.Whether a particular color is obtained by adding colored lights together or by subtracting some light from the total spectrum,the result looks the same to the eye.The additive process was employed for early color photography. But the subtractive method,while requiring complex chemical techniques,has turned out to be more practical and is the basis of all modern color films.What explanation is given for the use of the subtractive method in modern color films?A: The additive process is still being developed.B:The subtractive process is more efficient.C:Subtractive colors are more realistic.D:Additive chemical techniques are too complex.
Around the world more and more people are taking part in dangerous sports and activities．Of course，there have always been people who have looked for adventure--those who have climbed the highest mountains，explored（探险）unknown parts of the world or sailed in small boats across the greatest oceans．Now，however，there are people who seek（寻找）an immediate thrill（令人激动的事情）from a risky activity which may only last a few minutes or even seconds．I?would consider bungee（蹦极）jumping to be a good example of such an aetwity．You jump?from a high place（perhaps a bridge or a hot air balloon）200 metres above the ground with an elas-tic（弹性的）rope tied to your ankles．You fall at up to 150 kilometres an hour until the rope stops you from hitting the ground．It is estimated that 2 million people around the world have now tried bungee jumping．Other activities which most people would say are as risky as bungee jumping involve（包括）jumping from tall buildings and diving into the sea from the top of high cliffs．Why do people take part in such activities as these?Some psychologists（心理学家）suggestthat it is because life in modern societies has become safe and borin9．Not very long ago，people’s lives were constantly under threat．They had to go out and hunt for food，diseases could not easily be cured，and life was a continuous battle for survival．Nowadays，according to many people，life offers little excitement．They live and work in?comparatively safe environments;they buy food in shops;and there are doctors and hospitals to look?after them if they become ill.The answer for some of these people is to seek danger in activities such?as bungee jumping.In bungee jumping,you__________.A.jump as high as you canB.slide down a rope to the groundC.attach yourself to a rope and fall to the groundD.fall towards the ground without a rope
