But it is also true that many children today are using computers at school before they can write. What does this mean for the future? Are these children lucky or not?Many people who do not know about computers thinks of them as machines that children play with it. They worry that children play with it. They worry that children do not learn from experience but just from pressing a button and that this is not good for them. They think that children are growing up not knowing about the real world.But people who understand more about computers see that computers can be very good for children. A computer can help them to learn and to think for themselves. And for the future, don t we need people who can think clearly. Who know how to get information quickly and use it well? What do you think?46.According to the passage, in which four places can you find computers?A. At home, in office, in factories and in schools.B. At home, in schools, in banks and in offices.C.

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 books and newspapers 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 records or 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 6 hours a day or even more. 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 learnt quickly or slowly , it is hard work. Machines and good books will help, but they can t do the students work for him.51.Now a foreign language is learnt_.A. in the same way as it was in the pastB. quite differently from the pastC. only in the country where it is spokenD. only with the help of machines52.
