maybe should consider some other ways~~~~i found American movies are more useful than BBC, or you can try DISCOVERY CHANNEL in NUSCAST.
visual and audio impact will give you deeper understanding, and easier for you to imitate.
another good point: some excuse to watch movies :D:D:D
个人认为有的电影的对白实在太难听懂了
,特别是那种有口音的,含糊不清的。。。。 相比下来,BBC这种比较正统严肃的电台要好懂的多,discovery channel的确是个不错的选择,有可以练听力,还可以开眼,还有两个频道,Animal Planet 和National Geographic Channel,也很好,三个台都有中文字幕,你看的时候能保证不看么?呵呵~~~~
