   the bermuda triangle(百慕大三角) is in the atlantic ocean, near florid in the usa. during the past 60 years more than 1,000 seamen in ships and pilots in the planes have lost their lives. it is known as the triangle of death for its strange sea water and sudden storm. what’s the strangest is the light of the sea water which looks
 so bright that it can be seen even from an outer spaceship.
   at 2:00 p.m. on december 5, 1945, five planes took off in fine weather from the airport of florida, on a training task. two hours later, the leader in the sky radioed that he was completely lost. then there was silence. another plane was sent to look for them and it also disappeared.
