- Как вы считаете, могла ли Россия выиграть Первую Мировую войну, ведь Турция уже не представляла угрозы, Австро-Венгрия уже в 1916 году оказалась на гране катастрофы, оставалась только Германия, которая тоже уже еле держалась ( в плане экономики ). Есть мнения, что большевики победили только благодаря помощи из вне ( Англия, США,Германия ), так как после плодов победы, Россию уже точно было не остановить?

A.
The St. Petersburg Metro has been open since 1955 and carries almost 2.5 million passengers daily. Because of the river Neva and the city’s interesting relief, the Metro is one of the deepest subway systems in the world. The system’s deepest station, Admiralteyskaya, is 105 meters below ground because it is situated under the river.
B.
The London Underground is the world's oldest underground system. It has lots of dark tunnels and passages where you can get lost. They say that some stations are visited by ghosts. On the Piccadilly Line there appears a man dressed in an evening suit. Some staff members have refused to work at the station because of him. They’re just too afraid.
C.
In Paris no building is more than 500 meters away from a subway station. In the past the Paris metro offered a choice between 1st and 2nd class tickets. A 1st class ticket was more expensive. There were no other differences between the two classes. The result was that the first class trains were just less crowded. The difference existed till 1991.
D.
The Tokyo underground system is extremely clean and unusually modern. It’s also very punctual: trains are always on time. At rush hour the metro is always overcrowded. The Tokyo subway has about 8.7 million passengers every day. The carriages are always packed. There are even special platform assistants who push people inside so that the doors can close.
E.
The Metro in Washington DC has its own police. At each station police officers patrol to see if there is any trouble or danger around. Eating, drinking and smoking is not permitted in trains or stations. Anyone who enters the underground may be asked to open their bags for inspection. All this is done to protect the passengers as the metro is usually quite crowded.
F.
The Stockholm Metro is one of the most picturesque underground systems in the world. Artists, painters and sculptors have turned 90 subways into displays of their art. As a result the subways are decorated with pictures, frescos, and graffiti. For example, at one station there's a whole wall showing the history of different human civilizations.
G.
The Dubai Metro is a well-planned automatic metro system in the United Arab Emirates. All trains and stations have air conditioning and are extremely clean. Every station has links with bus stops, taxi stands and places to lock bicycles. What's more, stations are like mini shopping centres, because there are food shops, travel offices, and even banks there.-
