Part 2. Reading.
Read the text and do the tasks below.
Russia’s northern regions are on the Arctic Ocean, which is a sea that is frozen throughout the year. There is a sea travel from Russia’s shores into this frozen world, but it takes more than a normal ship to get through it. How do Russians manage to make their way through all the ice?
The Yamal is an icebreaker – it’s a ship that is specially designed to break through the layer of ice. It is powered by nuclear energy, and not traditional petrol or diesel engines. Because of this, the Yamal is the most powerful ships in the world, allowing it to smash through ice with ease. The ship is made of thick, strong metal that can break through the ice during its travels.
The Yamal is named after the region where it normally stays in harbour – the Yamal Peninsula, an area of land in north-western Siberia. Specifically, the term “Yamal” means the “End of the Land” in the language of the Nenets, a tribe that lives in the region.
The Yamal was originally designed to keep lanes of travel open for other ships to use in the icy waters. It has never really been used for this purpose, however. Instead, since it was launched in October 1992, it has been used mainly to carry passengers on trips into the Arctic region. One of its cruises was to celebrate the millennium in 2000, when it travelled all the way to the North Pole, making it only the 12th such ship ever to do so.
Another voyage of the Yamal, during August and September 2009, was to collect the staff and equipment from a number of manned ice stations positioned throughout the Arctic, because these stations were scheduled to close. Each station was manned by 18 Arctic explorers, who conducted research in the region. The explorers, their companion dogs and 150 tonnes of supplies and equipment were all placed on the Yamal.
The Yamal is impressive to look at. The lower part of the ship is painted black, the very bottom is red, and the upper part is an attractive shade of orange. On the very front of the ship is the outline of a mouth with sharp teeth, to “frighten” the ice it encounters.
