Misha: Should they watch films in English?
Mr Grams: They can try, but they shouldn't get upset if they can't understand anything. They'll have to watch the same film again and again until they understand better. It is also a good idea to get a copy of the same film in Russian.
Misha: Is that all?
Mr Grams: Oh, no. They should listen to English cassettes and repeat things after the speakers. That will improve their pronunciation and their ability to understand.
Misha: But they are always listening to our teacher. Her English is very good. Isn't that enough?
Mr Grams: Unfortunately, it isn't. They have to listen to different accents. If they always listen to the same person, they won't be able to understand other people. So if they aren't able to talk to native speakers, they'll have to use the cassettes!
Misha: And what about grammar? They learn a lot of grammar rules by heart.
Mr Grams: You don't have to do that. Grammar is very important, of course, but they have to use it, not simply learn the rules. However, they should learn texts and songs by heart. Then they will have longer phrases, not only words in their memory.
Misha: Thank you very much, Mr Grams. You're my favourite teacher.
Mr Grams: That's very kind of you, Misha.
