【正确答案】 C

【答案解析】[听力原文] To many listeners, a speaker who uses disrespectful, obscene, or explicit language comes across as insensitive, unprofessional, and uneducated. And yet some presenters use crude language because (they say) it adds spice and 'most people don't mind'. While it may be true that most people aren't upset, it is a mistake to ignore the feelings of those who are genuinely offended. By the way, coarse language isn't an age-related issue, with the young unbothered and the old bothered. There are people of all ages who feel slapped in the face when they hear such words. Consider this: Advertising executive Ron Hoff tells of a business presentation in which the speaker was trying to sell his company's services to a public utility firm. The speaker liberally sprinkled his talk with four-letter words, plus some five-letter varieties not often heard in public. There were 17 people in the audience, including one man 'whose body actually shivered a little every time he heard one of those words,' says Hoff. 'I watched him carefully. It was like somebody grazed him every few minutes with an electric prod. His body language attempted to cover these jolts he was receiving (he'd cross his legs, cover his face, slouch in his chair—nothing worked). He physically recoiled from the language he was hearing.' That man, it turned out, was the highest-ranking representative of the firm, so it came as no surprise when the firm declined to buy the services of the speaker's company. Hoff later asked the speaker why he had used so much crude language. 'Oh, they love it,' he said. 'They talk just like that all the time.' 'Yeah,' Hoff said to himself. 'All of them except one.' Q: Why do some presenters use crude langrage?
