单项选择题

Have you ever noticed advertisements (广告) which say "Learn a foreign language in 6 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 learnt 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 hooks and records or tapes; some use radio or television programmes; others go to evening classes. If they use the language only 2 or 3 times a week, learning it will take a long time, like language learning at school. A few people try to learn a language more quickly by studying for 6 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 ex ample, scientists and doctors chiefly need to be able to read books and reports in the foreign language. Whether the language is learnt quickly or slowly, it is hard work. Machines and good books will help, but they cannot do the student’s work for him.
