There are times when you find yourself unable to work out a problem. It is at this   1   that the way in which you use your teacher is important. With a good teachers such times should be less frequent than with a bad one, so the  2  the teacher, the more responsibility you have for your success! Whatever your luck in this   3   , one thing is most significant and stays the same, whatever the quality of teaching you   4   : if there is something you don.t understand, you must ask, again and again if necessary, until you do understand it fully.  5  as this may seem, it is almost unbelievable how many people would rather sit in silent ignorance than admit not understanding. To behave in such a way is the only truly   6  thing a student can do: it.s a false form of pride, which is the most useless, damaging quality anyone can have, to say  7    of a student! Therefore, regard your teacher as a guide or even a friend and do not sit    8   wondering what he.s going on about. You may also ask a friend or classmate for help. Remember, there.s always someone who is better than you in your class. And many newspapers and magazines set the special    9  for students, you can write to them and get replied in time. Listen to the radio, watch good TV   10   more often, maybe at a certain moment you.ll find your question is being explained there and then.
