                                                   How to practice spoken English?
      How can we practice our spoken English?
      The first and the most important thing is to believe   1  . You should always be full of confidence or you   2  
be able to improve your English. You should often encourage yourself. "Come on, don't be afraid!"
      You should never lose heart and never give up. 
      Maybe you are afraid of losing face, but you should think since we are students and we're   3  , there's no
need to worry   4   anything. You must always be active in practice. There's no problem that your pronunciation
and intonation (语调) can't be as good   5   the native people because we are Chinese, and we don't have
chances to live in foreign countries and talk with the people there   6  . But you must know that the main way to
study English is to make ourselves understood and   7   other people. You should believe that native speakers will
not laugh at you.   8   they will encourage you. So if you are brave enough you'll certainly make a rapid progress
in your   9   English. 
        10   be shy or afraid! Just have a try.
