xxxii Sometimes,  students  feel  tired  and  bored  to  listen,  if  the  discourse  is  too  long.
They  also  feel  more  difficult  to  concentrate:  The  solution  of  this  problem  is similar with the third problem.
Similar to Penny Ur 1996: 113, Rost 1994: 119 has identified the listeners problems  as  follows:  acuity  of  hearing,  discrimination  and  auditory  perception,
attention  and  concentration,  comprehension  including  four  aspects,  namely:  factual or literal comprehension,  interpretation, critical  listening, and evolutional listening.
5.  Difficulties in   Listening
According  to    many  experts    among  others  Dunkel,  1991;  Richards,  1983; and Ur,  1984, there are  eight  factors  making listening  difficult  as  follows:
a  Clustering Because of  the limitation of memory and  predisposition for clustering, we need
to    break  down  speech    into  small  groups  of  words.  In  teaching  listening comprehension,  the  teacher  needs  to  help  students  to  pick  out  manageable
cluster of words. b  Redundancy
Spoken    language  is  different  from    written  language,    it  has  a  good  deal  of redundancy.  So,  the  learners    might    initially  get  confused  by  this,  they  need
some training to  take advantage of redundancies as  well as  other markers that provide more  processing time.
xxxiii c  Reduced form
Spoken language has also many reduced forms. Reduction can be morphological, phonological, syntactic , pragmatic and so on.  These reductions  pose significant
difficulties, especially for  classroom learners  who  have initially  been exposed to  the full  forms of  English language.
d  Performance  variables Everyday  casual  speech  by  native  speakers  also  commonly  contains
ungrammatical  forms,  they    might  be  understood  easily  to  native    speakers,  but
might not  be easy to  second language learners.
e  Colloquial  language English  learners  might  have  difficulties    to  deal  with  colloquial  language.
Colloquialisms  appear  in  both  monologues  and    dialogues,  they  make    learners have  difficulties    to  listen  to    them.    Colloquialisms    cover      idioms,  slang,
reduced forms and  so on. f  Rate of delivery
Virtually    every  language  learner    thinks  that  native  speakers    speak    very  fast. The speed of  speaking can influence  the understanding  of  the listeners.
g  Stress, rhythm, and intonation The  prosodic    features  of  the  English  language    are  very  important  for
comprehension.  Because  English  is  a  stress-timed  language,  English  can  be    a
xxxiv terror for learners as mouthfuls of syllables  come spilling out between stressed
points. h  Interaction
Conversation  is  especially subject to all the  rules  of interaction  : negotiation, clarification, attending signals,  turn-taking,  and so on.  So,  learning to listen is
also    to  learn  to  respond  and  to  continue    a  chain  and    responding.  Learners should be trained that  good listeners  are good  responders.
