摘　　要：本研究分析了视频的语速、类型以及受试的特定词汇知识对其视听难易度感知和实际理解情况的影响。71名正在国内某高校修读大学英语课程的一年级学生观看了以不同语速播放的三段新闻和三段演讲,并完成相应的视听理解练习和问卷调查。结果表明,语速变化(140wpm,166-170wpm,195wpm)会影响难易度感知,但不会显著影响视听理解;视频类型(新闻vs.演讲)会对视听理解和难易度感知产生显著效应;生词率与视听理解、难易度感知都显著相关。笔者分析讨论了上述研究结果,并对外语教学中视频材料的选择提出了相关建议。This study reports an investigation of the impact of speech rate,video genre and knowledge of specific vocabulary on perceived and actual viewing comprehension. 71 Chinese first-year college students,who are taking a College English course,watch three news reports and three lectures,delivered at different speech rates,and complete comprehension tasks and a questionnaire. It is shown that speech rate（ 140 wpm,166-170 wpm,195wpm） produces main effect on perceived task difficulty,but not on actual comprehension; video genre（ news reports vs. lectures） produces main effect on both perceived difficulty and actual comprehension; knowledge of specific vocabulary is significantly correlated with perception and comprehension. These results are analyzed and suggestions are offered with regard to the selection of videos used in EFL class.
