Do I really improve my listening if I often listen to English program?
If you have English-language DVDs and there's an English subtitles option (sometimes available for the hard of hearing), a great way to learn is to have the subtitles on, sellotape a flap over the subtitles, listen and then lift the flap to see how closely your understanding matches the subtitles. It's a great way to focus on the spoken word and you'll soon be seeing your success rate shooting up.
(I myself watch English-language films with subtitles on but that's because my TV is ancient and the sound is awful!)
That's right. I also think the rythm of language is important and it is one of things I must improve. Watching English-language DVD is a good idea. I will try it. Thanks. :D
