ответить на вопросы по данному тексту (1) Signaling technology has undergone the same revolution as telecommu-nications. Availability of powerful computer equipment and rapid information exchange techniques have led to more sophisticated signaling systems. These systems are not only able to drive the train, but decide when is the optimum time to brake, coast or accelerate for maximum energy efficiency. These abilities have allowed on-board computers to provide much more necessary information for a driver which was impossible some years ago.
(2) On the one hand, with the exception of some newly constructed lines, the cost of providing continuous data exchange between track and train can be high. On the other hand, up-to-date signaling systems help to save time which is of great importance for train operation. Secure coding of information has increased the effectiveness of in-termittent ATC and increased the quantity of data that can be handled.
(3) Although developed for metro lines, various components of ATC are in-creasingly being applied to main lines, because they provide automatic train protection, control and operation.
(4) Needless to say that safety has become a political question, forcing a reappraisal of what level of signaling technology is required. More and more practical railway engineers realize that ATC is essential for safe operation, even though statistics do not always support this view.
(5) Introduction of ATC is important from economic point of view. Thus, in metro driverless operation may help to save labour costs.
(6) It is quite clear that no modern railway can exist without ATC. Neverthe-less, introduction of this system is not such an easy task as it may seem at first sight. At present it’s a headache for many European railways. As we know many more high-speed railway lines are being constructed, more and more trains are being designed and produced specially for cross-border operation. All this makes operators’ work more re-sponsible and nervous. New up-to-date ATC facilities must be installed, and their de-sign, manufacture and installation require great expenses. But this work must be done, because to benefit from ATC system railways are to use it throughout their networks.
1. What was the result of introduction of powerful computer equipment?
Availability of powerful computer equipment and rapid information exchange tech-niques have led to more sophisticated signaling systems.
2. What are the main functions of sophisticated signaling systems?
These systems are not only able to drive the train, but decide when is the optimum time to brake, coast or accelerate for maximum energy efficiency.
3. Was it possible for a driver to receive all the necessary information some years ago?
These abilities have allowed on-board computers to provide much more necessary in-formation for a driver which was impossible some years ago.
4. Is it expensive to provide continuous data exchange between track and train?
With the exception of some newly constructed lines, the cost of providing continuous data exchange between track and train can be high.
5. Where are various components of ATC being applied?
Various components of ATC are increasingly being applied to main lines, because they provide automatic train protection, control and operation.
6. Do you think that safety is a political question? Can you give any reasons?
Safety has become a political question, forcing a reappraisal of what level of signaling technology is required. Because the safety of citiziens is the most problem of the author-ities
7. Why is introduction of ATC important from economic point of view?
Thus, in metro driverless operation may help to save labour costs.
8. Is introduction of ATC an easy task?
Introduction of this system is not such an easy task as it may seem at first sight.
9. Is an operator’s work responsible and nervous?
Yes, it is.
10. Why is it vital to introduce automatic train control?
As we know many more high-speed railway lines are being constructed, more and more trains are being designed and produced specially for cross-border operation.

Dragon, flying, approached the planet, fell and died. The skeleton of his deeply entered the ground and stone ... "That's what the old Mongolian tale." Parts of the skeleton dragon "bones zakamenevshie lizards had long since been known to the Mongols, roamed the great expanses of the Gobi Desert. Expanses of Central Asia became known European science known only after traveling NM Przewalski GEGrumm Grzhimailo, PK Kozlov, VA Obruchev. in 20's. this century Academician AA Borisyak made a bold hypothesis: Now barren, desolate and deserted lands were once the center of Eurasia, the cradle of the animal world of Eurasia and part of Africa. searches on dinosaurs in the Gobi Desert to send a large expedition of 150 camels and 8 cars. It was attended by 40 specialists, restorers, photographers from the United States. The route covered 3000 kilometers. were found abundant "deposits" bones dinosaurs and other prehistoric animals.

It was in the early 20's., When the young Soviet republic, as only that formed the Mongolian People's Republic, it was necessary to solve the problems are more pressing than the search for dinosaur fossils. However, from 1946 GV Gobi expedition of paleontologists of the Soviet Union, Poland, the Mongolian People's Republic - and every expedition makes sensational discoveries of fossilized creatures. Cemeteries dinosaurs discovered in a great desert - the Sahara. "Right in front of us, on top of the dunes, lay ten-snake. Just then came the full chain, folded, as seemed from afar, from simple stone. Blue, blue, sky-blue stones - in fact, part of the skeleton, bones. She was also a ten-snake skeleton. Behind her I could see the extraordinary dimensions of the head, buried in the sand and stones, in the neighborhood - dozens, hundreds of tusks and teeth.

Everything around produced a fantastic, magical, blinding common sense impression. Here is the tail of prehistoric monsters izvivshiysya in the last convulsive movements, that edge, seeming branch of a mighty tree, here are some strange at first sight of the skeleton - blue, frightening dimensions ... The cemetery stretches further than the eye can see. Here, to die, came prehistoric dinosaurs, then they were the last meters of its own debt, desperate marathon ... It should move the sand with his foot, as there are new light zakamenevshie the skeleton, there for a moment - and the wind then put them back. World of dinosaurs before us as a living, the impression that it was like then, many centuries ago. "It describes the cemetery dinosaurs on the southern outskirts Sahara Italian correspondent Sandro Ottolenghi.

Accumulations of dinosaurs bones found not only in deserts. Giant dinosaurs discovered in prehistoric strata of Western Europe and North America. America. In the Middle Volga region, in the fields of oil shale, in the last century found remains of oceanic dinosaurs. The fossilized skeletons of dinosaurs predecessors, their fathers and uncles, reptiles, animal teeth, and had kind of animals are found in the region of Perm, and Australia, on the island of Spitsbergen and Antarctica ice cap covered!

School is an integral part of any child's life! There you can make friends, learn new things and have fun. But still, in order not to cause chaos in the school, some rules are needed. Basic school rules - the usual snouts that are easy to implement. One of the elemantar rules is discipline, each student must come before the lesson begins. Also in the school there are many unspoken rules, for example, rudeness and rude vision has never been welcomed in schools. Although there are many rules in schools, but oam

Объяснение:

Школа є невід'ємною частиною життя будь-якої дитини! Там ви можете завести друзів, дізнатися нові речі і отримувати задоволення. Але все-таки, для того, щоб не було хаосу у школі, потрібні деякі правила. Основні правила школи - звичайні правила , яких легко дотримуватись . Одним з елемантарнмх правил є дисципліна, кожен учень повинен прийти до початку уроку. Також у школі є багато не офіційних правил, наприклад, грубіянство і агресія ніколи не вважвлись нормою в школах в школах. Хоча є багато правил в школах, але там весело!
