【简答题】
It was on April 10, 1912, when the Titanic (泰坦尼克号) sailed for New York. She was carrying more than 2200 people. At that time she was not only he biggest but also the finest of all ships, for she had six compartments( 密封舱 ) with her. If four of them were broken, she would still be able to stay on the water. Four days after setting out, while the Titanic was sailing across the ocean, the man on watch suddenly saw a very large iceberg (冰山) , 100 feet tall. The great ship turned in time, but before long there was a sudden sound from below. The noise was so low that no one knew what had happened. The captain went down and was greatly surprised to see that five of her compartments had been broken. The Titanic was going down fast. The captain (船长) gave the order to give up the ship and hundreds of people jumped out into the water. At least over 1500 people lost their lives because there were not enough lifeboats.
