Unit four : I. Read the passage below and choose one correct answer for each question: Have you ever noticed advertisements 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 one’s mother language. 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 many millions of people start learning one. How do they do it? Some people try at home, with books and records of tapes; some use radio or television programs; 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 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 student’s work for him. 1. According to some advertisements, you ………………..
