 himself as Profe, which means teacher in Spanish.  4  , his warm smile and   5   words eased(减轻) my fears.
That year, I   6   his classes a great deal because I learned   7   just Spanish.
      I admit I only speak a little Spanish.   8   I try to live out the life lessons I learned from Profe.
     Every day Profe stood   9   his classroom before and after class to give his"hand hug". After school his room was always filled with students and he would    10   to and chat with them----  11   those not in his class. He
taught me that every person is   12   your time.
      One time, I was rejected(排挤)by my friends, Profe told me,"Lindita, life gives you  13 . But learning its
lessons will turn those ashes to jewels." Therefore, I learned to look at my troubles   14   and not to fear any
difficulty.
     In my senior year, I   15   president of one of the school's clubs, so I was very   16  . Many times I didn't
even have time to buy lunch. He served me by giving me his food as well as advice. He   17   out what he taught
us to do:   18   others.
     The author William Arther Ward  19  : "The mediocre(平庸的) teacher tells. The good teacher explains. The
superior teacher demonstrates(示范). The great teacher   20  ." Thank you Profe, for inspiring me.
