It depends on where you are in English learning and what materials you are listening to?If you are familiar with what you are listening to,of course you can do other things while listening .but if the materials are a little bit difficult for you to hear clearly,I thinks you had better listen to them with your heart.
Could i practise listening like this:
i am doing other things with listening english .i could not listen clearly.
It can do use for listening ??or pay all my attetion to listenning not doing other things??
now I am practising listening,and I think you must pay all your attention to listening when you are practising. Of course more listening is good, but I thinks listening with your heart is more important.
