     In schools all over the world boys and girls are learning foreign languages.   1   knows his own language,
but   2   is very useful, especially when we travel to other countries. If we go to France, we ought to be able
to speak   3  , and in Germany people will   4   us to understand German.
     How many languages are there in the world? There are about fifteen hundred, but many of them are not
very   5 . English is one of the most important languages   6   so many people use it, not only in England and
the USA,   7   in other parts of the world. More than 200,000,000 speak it   8   their own language, and about
another 200,000,000 use it as a second language. It is   9   to say how many people are learning it. Many
millions of school boys and school girls are trying to do so.
     English children study French, which is also a very  10  language. An Englishman can  11  find someone
in almost all parts of the world who is able to talk to him in either English or  12 .
     Which is the best way to learn a language? We should remember that we all learnt our own language well
when we were children. If we could learn a second language in the same way, it would not seem so  13 .
Think of what a child  14 . It listens to what people say, and it tries to imitate (模仿) what it hears. When it
wants something, it  15  ask for it. It is  16  the language, talking in it, and thinking in it all the time. If people
had to use a second language all the time, they would learn it quickly. 
       17  is also important to remember that we learn our own language by hearing people speak it, not by
seeing  18  they write. We imitate (模仿) what we hear. In school,  19  you learn to read and write as well
as to hear and speak, it is  20  to learn all the new words first through the ear. You can read them, spell them,
and write them later.
