Conversation 1 M： （1） Mr Brown‘s lectures are so boring。 W： Yes， he is not a very exciting speaker。 But the subject is interesting。 M： During every one of his lectures， I try to listen I really try。 But after about 10 minutes my mind begins to wander and I lose concentration。 But I see that you seem to be OK。 How do you stay focused through the entire hour？ W： Well，（2） what I do is keep my pen moving。 M： What do you mean？ W： It‘s a method of active concentration I read about。 One of the most effective ways to concentrate is to write things down。 But it has to be done by hand， not typing on a keyboard。
 You see writing by hand forces you to actually engage with what you’re learning in a more physical way。 M： Do you review your notes afterwards then？ W： Sometimes but that‘s not important。 My notes may or may not be useful but the point is that by writing down what Mr Brand says I can follow his line of thinking more easily。 In fact， sometimes I draw a little too。 M： （3）You draw in class and that helps me pay attention？ W： Yes， honestly it works for me。 I just draw little lines and nonsense really。 It was also in that article I read。 It can keep the mind active， prevent getting bored and help to concentrate。
 Again the point is to listen hard while keeping the pen moving。 If I‘m at home and I need to study what I do is read out loud。 It has a similar effect to writing by hand。 It helps memorize 
information in a physical way。
