Question

19．At 2：30 on December 5，1945，five US Navy training planes took off in clear weather from the base Lauderdale，Florida．The planes flew cast over the coast…and disappeared．The group was Flight 19，on a run between Florida and Bahamas．Tailor was the group leader．At about 3：40，Tailor reported that his compasses were not reading properly．The other planes followed their leaders aimlessly，first east，then west，then northeast over the ocean，as Tailor tried to make sure of the direction by radio．Then，suddenly Tailor was heard to give orders to dive…
Quickly，two giant Martin seaplanes were sent up to search for Flight 19．Several hours later，the wind became strong and visibility （能见度） dropped．A return to base was ordered．But only one of the Martin seaplanes landed．Four days later，the Navy and Coast Guard combed a 100，000 square miles area with more than 100planes and ships．No sign was ever shown of the missing planes．
Today，people have noted the disappearance of many ships and planes in the southwest part of the North Atlantic and began to call this area the Bermuda Triangle（百慕大三角区）．
The points of the triangle are Bermuda，Puerto Rico and a spot in the Gulf of Mexico，west of Florida．It is a two-faced water world of tiny islands，bright beaches and beautiful waters．Yet thick fogs，powerful currents（激流） and sudden storms are hidden behind this smiling surface．

12．Why did Flight 19 disappear？D
A．Because the wind became strong and visibility dropped．
B．Because Tailor was given wrong orders to dive．
C．Because Tailor couldn't read his compasses correctly．
D．Because something unknown made the compasses unable to work as usual．
13．In what position did Flight 19 disappear？A
A．In the southwest part of the North Atlantic Ocean．
B．In the northeast part of the North Atlantic Ocean．
C．To the southwest part of Bermuda in the Atlantic Ocean．
D．To the northeast part of Bermuda in the Atlantic Ocean．
14．How many planes disappeared altogether that day？B

Answer 1

分析 本文属于新闻类阅读，作者通过这篇文章向我们介绍了飞机在百慕大三角失踪的事情．

解答 12．D  细节理解题，根据第一段The group was Flight 19，on a run between Florida and Bahamas．Tailor was the group leader．At about 3：40，Tailor reported that his compasses were not reading properly．The other planes followed their leaders aimlessly，first east，then west，then northeast over the ocean，as Tailor tried to make sure of the direction by radio．可知19号航班消失是因为某种未知的东西使指南针不能正常工作，故选D．
13．A  推理判断题，根据第三段Today，people have noted the disappearance of many ships and planes in the southwest part of the North Atlantic and began to call this area the Bermuda Triangle可知19号航班是在北大西洋的西南部消失的，故选A．
14．B  推理判断题，根据第一段five US Navy training planes took off in clear weather from the base Lauderdale，Florida．The planes flew cast over the coast…and disappeared．The group was Flight 19，on a run between Florida and Bahamas可知一共有六个航班消失了，故选B．
15．D  词义猜测题，根据第二段Four days later，the Navy and Coast Guard combed a 100，000 square miles area with more than 100planes and ships可知海军和海岸警卫队找遍了十万平方英里的面积，故选D．

点评 考查学生的细节理解和推理判断能力．做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确选择．在做推理判断题时不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
