with out-of-class matters in class, or sometimes just for fun. Some other students listen to MP3 players
when they are having a lesson that they are not interested in.

first class in which students were sleeping or talking to each other. It seemed that learning well   5   nothing
to do with them," she says. "At first, I got worried about this, but then I said to myself, 'You're teaching   6  ,
and you need to manage this … These students need to know more about manners. It's time to help them
develop some good   7  . They shouldn't waste time doing nothing when they are young. Sooner or later, they
might regret the time they have wasted.'"

her suggestions:

importance   9   giving some homework that students must turn in next time.
