Have you ever noticed an advertisement which says "Learn a foreign language in six weeks, or your
money back! From the first day your pronunciation will be excellent. Just send…" and so on? Of course,
it never happens quite like that. The only language that is easy to learn is the mother tongue. And think
how much practice that gets! Before the Second World War people usually learned a foreign language in
order to read the literature (文学) of the country. Now speaking the foreign language is what most people
want. Every year many millions of people start learning one. How do they do it? Some people try at home,
with books and tapes; some use radio or television programmes; others go to evening classes. If they use
the language only two or three times a week, learning it will take a long time, like language learning at school.
A few people try to learn a language fast by studying for six or more hours a day. It is clearly easier to learn
the language in the country where it is spoken. However, most people cannot afford this, and for many it is
not necessary. They need the language in order to do their work better. For example, scientists and doctors
mainly need to be able to read books and reports in the foreign language. Whether the language is learned
quickly or slowly, it is hard work. Machines and good books will help, but they cannot do the students work
for him.
