     Many language learners think their pronunciation is good enough because their teacher doesn't correct
them too often or because other students can _1_ them.
     Pronunciation is the area which is _2_ the least attention to in language learning. Most teachers _3_
just let their students speak and stop them   4   they say something completely wrong. Working on each
student's pronunciation in class is just  5  . Also, the students who are    6   at pronunciation may be afraid
that it will embarrass their classmates if they help    7   their mistakes.
     If you believe your pronunciation is good enough to    8   because it is good enough for your teacher
and other students, you may be   9   when you actually go to a foreign country. One of my friends was
the best student in his   10   class in Poland. When he went to America, he found Americans didn't
understand   11    of what he said.
     Your pronunciation may still be quite    12   that of a native speaker. If this is the  13  ,  other people
will find it    14   to understand what you're saying and will not be comfortable with you. 
         15  ,  don't think you can communicate in a foreign language   16   you've tested your skills on real
native speakers.    17   for native or nearnative pronunciation so that people you talk to can communicate with you  18  . In order to achieve this goal, there's   19    that you will need to start thinking about
pronunciation and   20   time on it.
