单选题
Where Did All the Ships Go

The Bermuda Triangle is one of the greatest mysteries of the sea. In this triangle area between Florida, Puerto Rico and Bermuda in Atlantic, ships and airplanes seem to disappear more of ten than in other pans of the ocean. And they do so without leaving any sign of all accident or any dead bodies.
It is said that Christopher Columbus was the first person to record strange happenings in the area. His compass stopped working, a flame came down from the sky, and a wave 100 to 200 feet high carried his ship about a mile away.
The most famous disappearance in the Bermuda Triangle was the U. S. Naval Air Flight 19. On December 5, 1945, five bomber planes carrying 14 men took offon a training mission from the Florida coast. Later that day, all communications with Flight 19 were lost. They just disappeared without a trace.
The next morning, 242 planes and 19 ships took part in the largest air-sea search in history. But they found nothing.
Some people blame the disappearances on supernatural forces. It is suggested the missing ships and planes were either transported to other times and places, kidnapped by aliens or attacked by sea creatures.
There are also natural explanations, though. The U. S. Navy says that the Bermuda triangle is one of two places on earth where a magnetic compass points towards true north instead of magnetic north. Therefore, planes and ships can lose their way if they don't make adjustments.
The area also has changing weather and is known for its high waves. Storms can turn up suddenly and destroy a plane or ship. Fast currents could then sweep away any trace of an accident.

单选题 Why the Bermuda Triangle is regarded as one of the greatest mysteries of the sea according to the passage?
【正确答案】 B
【答案解析】根据题干定位到第一段：百慕大三角是海上最神秘的区域之一，在这一位于佛罗里达、波多黎各和大两洋百慕大之间的三角地区，船只和飞机消失的比在大洋上的其他地区更频繁，而且消失之后没有留下任何事故的迹象或者遇难者尸体。可见百慕大三角之所以让人觉得神秘是因为很多船只和飞机在这里消失却没有留下任何迹象，B选项与此相符，故为本题的正确答案。
单选题 Which of the following was not a possible happening when Columbus was crossing the Bermuda Triangle according to the passage?
【正确答案】 D
【答案解析】根据题干定位到第二段：It is said that Christopher Columbus was the first person to record strange happenings in the area. His compass stopped working, a flame came down from the sky, and a wave 100 to 200 feet high carried his ship about a mile away(据说是哥伦布第一个记录下了这一地区发生的奇怪事：他的罗盘失灵了，火焰从天而降，100—200英尺高的大浪把他的船带出了大概一英里)，对照此处的描述和选项后发现只有D选项与原文不符，因此本题的正确答案为D。
单选题 How many people disappeared on in this area on the day December 5, 19457
【正确答案】 A
【答案解析】根据题干定位到原文第三段第二至四句：1945年10月5日，5架轰炸机带着14个人从佛罗里达海岸起飞执行训练任务，当天晚些时候，与该机队的所有通讯均失去联系，飞机和机上人员均消失得不留痕迹。由此不难判断当天消失的人数是14，因此本题的正确答案为A。B是飞机数，而不是人数，排除；其他两个数字是下面一段中提到的出动的搜寻这个飞行队的飞机数和舰船数，也排除。
单选题 Which of the following is not all assumption about the reason for the mysterious disappearances in the Bermuda Triangle?
【正确答案】 D
【答案解析】根据题干定位到第五段：Some people blame the disappearances on supernatural forces. It is suggested the missing ships and planes were either transported to other times and places, kidnapped by aliens or attacked by sea creatures(一些人把这些失踪事件归因于超自然力量。他们认为这些船和飞机或者是被运到了其他时空，或者是被外星人绑架了，或者是遭到海洋生物袭击)，没有提到的只有D，因此本题的正确答案为D。
单选题 What will happen to the ship crossing the Bermuda Triangle according to the U. S. Navy?
【正确答案】 B
【答案解析】根据题干定位到原文倒数第二段：The U. S. Navy says that the Bermuda triangle is one of two places on earth where a magnetic compass points towards true north instead of magnetic north. Therefore, planes and ships can lose their way if they don't make adjustments(美国海军说百慕大三角是世界上仅有的两个罗盘指向地理北方而不是磁极北方的地方之一，在这里飞机和船只如果不作出正确判断的话就可能迷失方向)，因此一定会发生的是B，即本题的正确答案。C选项太绝对，并不是不可能找到正确的方向，而是需要做出正确的判断才能找到正确的方向，故排除C。D选项的相关内容出现在最后一段，但是原文说这个地区天气多变，暴风雨可能突然到来，摧毁任何飞机或船只，但这并不意味着每艘经过的船只都会遇到暴风雨，因此排除D。
