模仿文本： But when did all this start? Did teenagers evolve or were they invented? And what role did film play? Next month, there's the chance to see a new film "Teenage", an imaginative documentary history, seamlessly blending archive, testimony and dramatisation from the early 20th century to the end of the war.

 

译文：但这一切的根源是什么？年轻人是慢慢转变成这样，还是生来如此？电影在其中又扮演怎样的角色？下个月，我们将有机会观看电影《少年》，一部融合了文件、口述和戏剧的虚构的纪录片，讲述了从20世纪初到二战结束时期的历史。
