Задание 1. Прочитайте и переведите текст (30 минут):
- Water and air pollution problems
Water and air pollution are the two main factors that destroy the environment in big cities. Paris has no industry, so the Seine is not polluted by industrial effluents but by sewer waters. However, this problem is being solved by building pollution control stations in a Paris suburb. The sewage is channeled into them and cleansed before it goes into the Seine. When visiting these installations, one can often see how pure water the processed water is – the engineers who work there drink it quite cheerfully.
Water is purified by mechanical and biological methods. The purified water is treated with chlorine and released into the rivers, whence it enters the water supply systems where it undergoes further and finer treatment.
Air is mainly polluted by heating systems and cars. When you look at a modern city from a hill top you get the impression of vapour (smog) lingering over the city especially when there are no winds which can air the city. However, when there is no wind they have smog. As regards heating, mazut and gas are used rather than coal for last years. The poisoned air is the most modern quarters of the city.
District heating is an effective method. Several heat-and-power plants generate steam, which is piped underground all round the city.
As for cars you know, of course, how heavy traffic is in big cities. The slower the traffic, the more exhaust fumes are. This problem will be solved in the near future.
The acuteness of the problem depends on how well the country is developed and on the number of the cars. Many of these problems are international in nature.

- Задание 3. Составьте правильные утверждения в соответствии с содержанием текста (15 минут):
| The higher the ratio between surface area and volume, The lower the ratio between surface are and volume, The smaller the size of the building, The larger the size of the building, The thicker the insulation of a building, The more compact the shape of a building, The less compact the shape of a building | the more quickly it gains or loses heat the more it retains heat the faster the rate of heat transfer the less it retains heat the more slowly it gains or loses heat the slower the rate of heat transfer |
Задание 4. Выскажитесь по одной из следующих тем в 10 предложениях, приводя аргументы (25 минут):
the ozone layer: a layer of gases. It stops harmful radiation from the sun reaching the earth; recent research shows that there is now a hole in parts of the ozone layer;
global warming: an increase in world temperature caused by an increase in carbon dioxide;
acid rain: rain that contains dangerous chemicals; this is caused by smoke from factories;
smoke from factories;
car exhaust fumes;
dumping (throwing away) industrial waste (unwanted material) in seas and rivers;
aerosol cans (usually called sprays); some of these contain CFCs (a chemical) which can damage the ozone layer;
cutting down tropical rainforests (e.g. The Amazon); this increases carbon dioxide in the atmosphere.
