Перевод!!!Most British students choose to go to university a long way from their home town: university is seen as a time to be independent, to live away from home and develop new interests.
British students do not have to pay to go to university, but do need money to live away from home while they are studying. Some students whose parents do not earn a lot of money are given a grant (money) from the local education authority. If students do not get a grant, parents pay for their children. Some students borrow money from the bank which must be paid back after they leave university. In theory, the grant pays for rent, food, books, transport and socializing. In fact, the grant is not a lot of money.
Students used to work1 during the holidays to earn more money, but it is now difficult to find such jobs. The result is that more students are dropping out, failing to finish their courses.
Not all students study full-time2 at university or college. Many people combine their studies with work. Some companies release their staff for training one or two days a week or for two months a year. Large companies often have their own in-house training schemes.
The British government is very enthusiastic about such training schemes, in particular because so few people go to university.
If you are unemployed, there are two forms of training schemes: employment training for people who have been out of work for a long time and Youth Training Schemes for school leavers who cannot find a job.

Перевод!!!Many experts on different subjects believe that there are already too many people in the world. Unless there are great changes in the way people think about the number of children they should have, the world’s population will double in twenty-five years. There will be more than 20 cities with population greater than 20 million people. At present there are only three.
Some people who do not understand what ‘overpopulation’ means point to countries such as Australia and say ‘But there is plenty of room there. The country is almost empty’. It is true that most of Australia is unpopulated, and much of it is very thinly populated, but there are reasons for this. Firstly, much of the land is desert and it is waterless, and secondly, even the land that is not desert is not suitable for anything, not even growing grass. Even with its present population of 17 million, Australia has serious water problems. Furthermore, if it has to feed more people, it will have less food to sell to other countries which, in turn, as their population grows, will have to buy more food from outside.
Another major problem we will have to face as the world’s population grows is a shortage of energy. We are using up coal and oil and when they have been exhausted, we will have to find something instead of them. It is true that we can make electricity from the heat of the sun and moving water, but we do not yet have the technology to produce great amounts of this energy.
Perhaps, though, the most urgent problem when the world’s population doubles will be pollution. The earth and the air we breathe are already badly polluted. Twice the number of people will cause twice the amount of pollution.
The world’s leaders have to solve many problems. Population control is the greatest. It is probably the one that many countries are doing the least about. Sadly, it is the poorer nations, especially in Africa, which have the greatest population growth, and their peoples will suffer even more than they are suffering now.
