Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.

Have you ever noticed advertisements which says “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. One’s mother language is easier to learn, but it also requires a lot of practice to be fluent. And think how much practice that gets! Before the Second World War, people usually learned a foreign language in order to read the literature of the country.

        Now speaking a foreign language is what most people want. Every year millions of people start learning one. How they do it? Some people try it at home, with books and records of tapes; some use radio or television programmes; some use computers and network; others go to evening classes. If they use the language only 2 or 3 times a week, it will take a long time, like learning a foreign language at school. A few people try to learn a the language fast 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 example, scientists and doctors chiefly 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.
