Tales of the unexplained
人类科技发展到今天，早已能够上天下海。那么人类是否已无所不能了呢？还是让我们先去看一看百慕大三角再下结论吧！
We like to consider ourselves the superior race，and we are.It's true that we are getting to know more and more，and we actually live in “the information age”．Our human vanity (虚荣心) makes us believe that we really have to know everything！
Surprisingly，we do not have this ability.The question “What is happening in the Bermuda Triangle？”is the very proof (证据)．
Where is the Bermuda Triangle located？The mysterious
triangle is believed to be situated between Florida，Bermuda and Puerto Rico，where too many unusual events have happened.
On December the 5th 1945，five U．S. military planes took off from Florida on a clear day only to disappear over Bermuda.Furthermore，some other disappearances took place：in 1947，an American C54 plane simply disappeared at 100 miles from Bermuda；at 80 miles，a Star Tiger plane disappeared in 1948.
Even Columbus had trouble in Bermuda.Some of his journals were about the strange happenings there：“the waters are changing their color”and “compasses are going wild”．
Maybe it's why it is called the Devil's triangle or the Atlantic cemetery (公墓)． Many hypotheses were stated in order to explain the strange events.In spite of these attempts，the mystery of the Bermuda Triangle remains unsolved.
Some people get to say that maybe aliens are involved in it.Other imaginative scientists relate the happenings in Bermuda to Einstein's theory，saying that the missing ships and planes are translated to another dimension of space and time and taken into another world.
Maybe we will just have to wait to go to Heaven and ask the one who made it.The answer will surely be a satisfying one!
