In today’s fast –paced(快步伐/节奏的)culture, many people may feel like they ‘re too busy to read a book. In fact, a recent survey found that reading rates (比率)are falling in the US. Young people in particular(特别的)are more likely to spend their free time watching TV or surfing the Internet than reading a novel or nonfiction(非小说类文学作品)book. According to the survey results, the average(平均) 15 to 24-year-old living in the US spends 2 hours per day watching TV, and only 7 minutes reading for pleasure. Considering all the high-tech forms of entertainment out there, from video games to cyberspace(赛博空间), maybe it’s not surprising that fewer people read these days. But is reading just an old-fashioned pastime, or is it a lost art? Marni,an office worker, said, ”I’m reading the most incredible(不可思议的) book right now, and I can’t even imagine not having that in my life, like not loving reading.” What ‘s your opinion?
