Unit 5 Revealing nature We like to consider ourselves the superior ① 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 ② 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. 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 colour” and “compasses are going wild”. Maybe it ’ s why it is called the Devil ’ s Triangle or the Atlantic Cemetery ③ .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 ④ 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! 词海拾贝 ① superior adj. 更好的 , 占优势的 ② vanity n . 虚荣心 ③ cemetery n . 公墓 ④ imaginative adj. 富有想象力的 典句欣赏 The mysterious triangle is believed to be situated between Florida,Bermuda and Puerto Rico,where too many unusual events have happened. 译文 : 人们都认为这个神秘的三角地带位于佛罗里达、百慕大和波多黎各之间 , 那里发生了太多不寻常的事件。 分析 : 在该句子中 be believed to do 表示 “ 被认为 ……”;where 引导定语从句 , 修饰先行词 the mysterious triangle 。 理解诱思 1 .What did the Columbus ’ journals tell us? 答案 : It told us there were some strange happenings in Bermuda Triangle. 2 .Why is the Bermuda Triangle called the Devil ’ s Triangle or the Atlantic Cemetery? 答案 : Because there have been many planes and ships disappearing over and in the Bermuda Triangle.
