Introduction Introductory Remarks The Bermuda Triangle. also called the Devils Triangle is an area of the atlantic Ocean off southeast Florida, where the disappearance of ships and airplanes on a number of occasions has led to considerable interest in unexplainable losses and other atmospheric disturbances. Violent storms and downward air currents frequently occur there, but studies have not produced any convincing answers to the mystery of the triangle. Nevertheless, there are still many theories about the area. Some people go so far as to suggest that the disappearances are caused by unknown magnetic forces from outer space or from the bottom of the sea.

四 川 建 筑 职 业 技 术 学 院 授 课 教 案 Unit 4 Text A The Bermuda Triangle I. Introduction 1. Introductory Remarks The Bermuda Triangle, also called the Devil's Triangle, is an area of the Atlantic Ocean off southeast Florida, where the disappearance of ships and airplanes on a number of occasions has led to considerable interest in unexplainable losses and other atmospheric disturbances. Violent storms and downward air currents frequently occur there, but studies have not produced any convincing answers to the mystery of the triangle. Nevertheless, there are still many theories about the area. Some people go so far as to suggest that the disappearances are caused by unknown magnetic forces from outer space or from the bottom of the sea. But there are still many people who don't recognize the triangle as a dangerous zone. They are convinced that "the majority of disappearances (in the triangle) can be attributed to the area's unique environmental features." Boundaries of the Bermuda Triangle are formed by drawing an imaginary line from Melbourne, Fla., to Bermuda, to Puerto Rico, and back to Florida. These boundaries vary, however, among many writers, if not all, who are trying to establish a Bermuda Triangle "mystery" by their mysterious accounts. Yet, so far, nobody is so certain. 2. Introductory Questions Exercise 1 Additional questions based on the Introductory Remarks: 1 ) Are there any studies which can clearly explain the mystery? 2) What is one of the interesting explanations given by some scientists and authors? 3) Why do some other people not regard the triangle as a dangerous place? 4) How do you look at this mysterious area? Exercise 3 after reading the passage II. Outline A. The Mysterious Disappearances (Paras. 1 - 3) l. 5 U.S. Navy bombers (Flight 19) (Dec. 5, 1945) 2.
