There will eventually come a day whenThe New York Timesceases to publish stories on newsprint. Exactly when that day will be is a matter of debate. "Sometime in the future," the paper"s publisher said back in 2010.Nostalgia for ink on paper and the rustle of pages aside, there"s plenty of incentive to ditch print. The infrastructure required to make a physical newspaper—printing presses, delivery trucks—isn"t just expen sive; it"s excessive at a time when online-only competitors don"t have the same set of financial constraints. Readers are migrating away from print anyway. And though print ad sales still dwarf their online and mobile counterparts, revenue from print is still declining.Overhead may be high and circulation lower, but rushing to eliminate its print edition would be a mis take, says BuzzFeed CEO Jonah Peretti.Peretti says the Times shouldn"t waste time getting out of the print business, but only if they go about doing it the right way. "Figuring out a way to accelerate that transition would make sense for them," he said, "but if you discontinue it, you"re going to have your most loyal customers really upset with you."Sometimes that"s worth making a change anyway. Peretti gives the example of Netflix discontinuing its DVD-mailing service to focus on streaming. "It was seen as a blunder," he said. The move turned out to be foresighted. And if Peretti were in charge at the Times "I wouldn"t pick a year to end print," he said. "I would raise prices and make it into more of a legacy product."The most loyal customers would still get the product they favor, the idea goes, and they"d feel like they were helping sustain the quality of something they believe in. "So if you"re overpaying for print, you could feel like you were helping," Peretti said. "Then increase it at a higher rate each year and essentially try to generate additional revenue." In other words, if you"re going to print product, make it for the people who are already obsessed with it. Which may be what theTimesis doing already. Getting the print edition seven days a week costs nearly $500 a year—more than twice as much as a digital-only subscription."It"s a really hard thing to do and it"s a tremendous luxury that BuzzFeed doesn"t have a legacy business," Peretti remarked. "But we"re going to have questions like that where we have things we"re doing that don"t make sense when the market changes and the world changes. In those situations, it"s better to be more aggressive than less aggressive." The New York Times is considering ending its print edition partly due to ______.
A. the high cost of operation
B. the pressure from its investors
C. the complaints from its readers
D. the increasing online ad sales
根据下面资料,回答题: 某市一炼油厂生产液态油料,原料为煤焦油。煤焦油是一种黏稠状的黑褐色液体,比水重,主要含有苯、甲苯、二甲苯、萘、茵、菲等芳烃及芳香族氧化合物,含氮、硫的杂环化合物等。 2013年5月8 日 13时30分,工人在清理4号炼油炉内的油渣时,致使油渣飞溅遇明火而发生燃烧。起火后,5名工人急忙取来一些被水润湿的麻袋,盖压起火的锅炉,效果不好,于是又找来4只灭火器,其中2只小灭火器没有喷出泡沫。待用大灭火器进行灭火时,上窜的火焰已经有10余米高。起火的4号炼油炉旁堆放有50桶每桶200 kg的煤焦油。在4号炉内有经过第一次加工留存的4 t混合油,与4号炉相邻的2号炉内有2 t左右油料,搅拌机中还有5 t煤焦油。13时50分,4号炉及其相邻的2号炉内油料燃烧,发生爆炸。 14时5分消防人员赶到现场,将4号炉包围。消防人员用了5 t泡沫灭火剂、25 t水才将火势控制住。15时35分,炼油厂大火全部扑灭。此次事故造成10名工人死亡,30名工人重伤。事故损失包括:医药费50万元,丧葬费15万元,抚恤赔偿金300万元,罚款100万元,补充新员工培训8.5万元,现场抢险费300万元,停工损失1000万元。 根据上述场景。回答下列问题(共16分,每小题2分,1~3题为单选题,4~8题为多选题): 危险化学品的主要危险特性有( )。
