What message does the speaker try to convey in this passage?

Watching movies is a good way to improve your listening: I would stress the usefulness of repetition. So watch a DVD of an English-language film with Chinese subtitles.Then,a week or so later,watch the film again with the subtitles covered up.This time,you will know broadly what the characters are trying to say, which will help your brain link the English words with their meanings.Of course,you can pause and rewind the film if there are certain bits that really puzzle you.
    The next step would be to find a way to listen to the soundtrack of the film without watching it.You should know the scenes and the story well by now,so by removing the pictures your brain will really focus on the language spoken.
    Before you do any of this,think carefully about what film you want to use to practice your listening.If you want to learn American English,be sure to watch a film set in the USA.If you choose a really well-regarded film,one that has won lots of Academy Awards,for example,you will probably be able to buy the screenplay of the film,which will be very useful to you.
    Lastly, choose a film that you are not going to get tired of if you watch it three times!
    This is a very satisfying way to practice your listening.You will really feel that you are improving.
