    The great ship, Titanic, set off for America in April 1912 on its first trip. It carried more than 1 000

people. 

    The Titanic was the largest and finest ship at that time and it had 16 compartments (密封舱). Even if

(即使) four of those compartments were broken, it would still be able to stay on the sea.

     Four days later, when the Titanic was crossing the sea, the man on watch suddenly saw a very large

iceberg ahead. The great ship turned in time, but soon there was a great noise from below. The captain

went down to see what the matter was. To his surprise, he found the ship was sinking fast because 5

compartments were broken! Hundreds of people jumped into the water. As there were not enough lifeboats,

about 1 500 lives were lost.
