Passage Two

Questions 51 to 55 are based on the following passage.

 

  You probably know about the Titanic, but it was actually just one of three state-of-the art(最先进的) ocean ships back in the day. The Olympic class ships were built by the Harland & Wolff ship makers in Northern Ireland for the White Star Line company. The Olympic class included the Olympic,the Britannic and the Titanic. What you may not know is that the Titanic wasn’t even the flagship of this class.All in all, the Olympic class ships were marvels of sea engineering, but they seemed cursed to suffer disastrous fates.

  The Olympic launched first in 1910, followed by the Titanic in 1911, and lastly the Britannic in 1914. The ships had nine decks, and White Star Line decided to focus on making them the most luxurious ships on the water.

  Stretching 269.13 meters, the Olympic class ships were wonders of naval technology, and everyone thought that they would continue to be so for quite some time. However, all suffered terrible accidents on the open seas. The Olympic got wreaked before the Titanic did, but it was the only one to survive and maintain a successful career of 24 years. The Titanic was the first to sink after famously hitting a huge iceberg in 1912. Following this disaster, the Britannic hit a naval mine in 1916 and subsequently sank as well.

  Each ship was coal-powered by several boilers constantly kept running by exhausted crews below deck. Most recognizable of the ship designs are the ship’s smoke stacks, but the fourth stack was actually just artistic in nature and served no functional purpose. While two of these ships sank, they were all designed with doucle hulls（船体） believed to make them “unsinkable”, perhaps a mistaken idea that led to the Titanic’s and the Britannic’s tragic end.

  The Olympic suffered two crashes with other ships and went on to serve as a hospital ship and troop transport in World War I. Eventually, she was taken out of service od 1935, ending the era of the luxurious Olympic class ocean liners.
