TRAMS MAY BE ON THE WAY BACK

1. The tram, discarded by many British cities before and after the war, may be heading for comeback.

2. Newcastle Passenger Transport Executive has commissioned a study of the feasibility of Converting the 20-mile north Tyneside loop railway into an electric light train оr tramway system.

3. The advantages of the tram are the following: it is considerably cheaper than the conventional railway, quieter, free from exhaust fumes, and able to provide a more frequent service with more stops. Renewed interest is being shown in both Europe and America, where existing systems are being extended and new up-to-date vehicles are coming into service.

4. Dr. Tony Ridley, director-general of the transport executive, said: "we are aware of the considerable amount of work that is being done in the development of such systems in various parts of the world, particularly in Western Europe.

5. "It is envisaged that such a railway would offer advantages not easily attainable with other transport systems. Having relatively small electrically powered stock, it would be silent in operation and devoid of fumes. It would therefore be more acceptable environmentally than the present railway.

6. By offering additional stops and a more frequent service, coupled with high performance, it could combine the attractiveness of a semi-express bus service with the operational advantages of a guided railway system."

MOLECULES FOUND IN SPACE

l. An unidentified radio signal that may be a clue to the chemical processes that are taking place in space has been discovered by the National Radio Astronomy Observatory, Kitt Peak, Arizona.

2. 0ne of the scientists, Dr. L. E. Snyder, reported to the International Astronomical Union meeting in Brighton that there is every reason to believe that the signals are coming from a chemical compound being formed in the clouds of dust in space.

3. Six different types of chemical have been detected in space by their radio emission.

4. In some cases the molecules are present to the extent of only one molecule in a cubic meter, but the clouds are so large that the total number of molecules is significant.

5. Astronomers have been surprised at the range of molecules that have turned up in these observations. Molecules of water, ammonia, carbon monoxide and formaldehyde, for example, have been found, recognized by their characteristic radio emissions. One question of course, is how these comparatively complex molecules are formed in the dark clouds.

6. Оnе possibility discussed at the meeting is that individual atoms come together to make molecules on the surfaces of the grain of dust composing the clouds. The dust grains are suspected to consist of graphite or, possibly, a silicate material.

7. The new radio signal has been detected in four regions of space. The signal was being recorded at the Kitt Peak Observatory. Dr. Snyder said he is fairly convinced that the signal is due to radio emission from a molecule, but so far nobody knows what type of molecule is responsible.

8. But the consensus at the meeting seems to be that a molecule made up of some combination of hydrogen, carbon, oxygen, and nitrogen atoms is probably responsible. These are the atoms making up the other types of molecule that have been detected in dark clouds.

9.0ne reason why astronomers believe it is important to discover what is happening in the clouds is that they are suspected to be made up of the kind of material from which the solar system was formed. It has also turned out that some indication of the way the clouds are moving can be found by measuring how the wavelengths of the signals are slightly shifted from what is expected for molecules at rest.

Слова и пояснения к текстy

grain – крупица (пыли)

consensus – согласие, единодушие

11. Ответьте на вопрос:

Why is it important to discover what is happening in the dark clouds?
