When TV news programmers report wars or diseases, the editors rarely use the most horrifying pictures of dead or wounded victims because they don’t want to upset their viewers. Even so, viewers are usually warned in advance that they“may find some of these scenes disturbing”, so they can look away if they choose. But the men and women whose job is to record those scenes, the TV cameramen, have no such choice. It is their duty to witness the horrors of the world and record them, no matter how unpleasant they may be. As a result, it is one of the most dangerous, exposed and emotionally taxing jobs the world has to offer. Today, the demand for their work is rising. The explosion of satellite broadcasting and 24hour news in recent years has created an almost insatiable（不能满足的）demand for TV information. But major broadcaster sand the TV news agencies（部）, such as Reuters and WTN, have never had enough staff（人员）to meet thje worldwide demand for up-to-date pictures, so increasingly they turn to freelance（自由职业的）TV cameramen. These freelance cameramen are independent operators tied to no particular organization. They will work for any company which hires them, for just a few hours or for several weeks in a war zone. But if the freelance cameraman is injured in the course of the job, the TV company is not responsible for him. The freelance must survive on his own. “TV will always need hard, vivid and moving pictures which are fresh, but these companies feel uncomfortable with large numbers of employees on their books.”Explains Nik Cowing, once a foreign editor for Britain’s Channel 4 news and now a BBC news presenter. “By hiring freelancers, they can buy in the skills they need only when they need them. It also enables them to reduce the risk.”He says. 小题1:In the last sentence of the first paragraph,“taxing”most probably means“ ”.
