One evening Rutherford entered the laboratory. It was late, but he found one of his students working with some apparatus. «What are you doing here so late?» Rutherford asked. «I'm working, sir,» was the answer. «And what do you do in the day time?» «Oh, I work, of course, sir,» answered the student. «Do you work early in the morning, too?»

«Yes, professor, I work early in the morning, too,» said the stu­dent, quite sure that the famous scientist would praise (хвалить) him.

Rutherford looked at him gloomily (мрачно).

«Tell me,» he asked with irritation (раздражение), «when do you think?»

Pollution

The British, like many other Europeans, are becoming more and more worried (беспокоиться) about their environment. Here are some of the environmental problems that they face.

As the population of large cities like London, Birmingham and Manchester continues to grow, pollution problems become worse.

The air in many towns and cities is being polluted by traffic (транспорт, движение) and industry. The number of cars and lor­ries is growing all the time. On the one hand, they bring mobility to millions of people, but on the other hand, they need bigger, better and more expensive roads, which often ruin the countryside (сельская местность). Traffic in cities is getting worse and worse. Water pollution has become a serious problem in many British rivers. People living near airports suffer from the noise of increas­ingly larger and more powerful jet airliners taking off and landing.

Ecological Problems of Big Cities

There are over 150 supercities in the world with population from one to 15 million and more. Tokyo, New York, London, Mexico City, Rio de Janeiro and Moscow are just a few of the cities which have become supercities.

People in the supercities suffer from polluted environment: bad water, bad air and noise. A new term, urban (городской) climate, is used now for such cities. It means high temperature, oppressive atmosphere and intensive smog.

Some experts consider that it is practically impossible to pro­tect the big cities from pollution. The World Health Organization (WHO) studied air pollution around the world for over eight years.

It measured two things: the level of sulphur dioxide (S0₂) in the air and the level of smoke. Sulphur dioxide and smoke pollute water and have serious effect on forest, buildings and health of people.

In the WHO report it is shown that the cities with the most con­siderable level of C0₂ in the air are Milan, Teheran, Prague, Santi­ago and Sao Paulo. However, some cities with clean air get worse in winter. Helsinki, for example, becomes one of the cities with the largest proportion of it in the air in winter. This must be connected with the heating of houses. One can also mention (упоминать) Glasgow and Warsaw which suffer in the same way.
