On the night of May, 7,1942, a plane took off from an Air Force base in England to stop German fighters over the English Channel. The pilot of the plane was Captain Thomas Nash. Looking eastward, Nash saw twelve orange lights in a row, moving at an extremely high speed. As an experienced flyer, he had never seen anything like them. Thinking that they might be a new German weapon, he decided to follow them. But when he swung the plane around and headed directly for the lights, they disappeared.
Captain Nash may have been the first to see such orange lights but he wasn’t the last. His experience was repeated several times by pilots during World War Ⅱ in Europe and the Far East. What were they? No one knows for sure, but there is an interesting theory to explain them. According to this theory, the orange lights are space animals – animals specially adapted to life in the upper atmosphere just as some creatures are adapted to life at the bottom of the sea. These space animals, the theory says, live so far up in the atmosphere that they are invisible from the earth. They feed in part on the air and partly on energy from sunlight. Being almost pure energy themselves, they can give light at night. During the day they become invisible.
Before World WarⅡ, continues the theory, there was little radiated (辐射) energy available on the earth’s surface. Then came the development of rockets, atomic reactor (核反应堆), and hydroelectric (水力发电的) plants. The space creatures are attracted by these sources of energy. At night when no energy is sent from sunlight, they go down into the lower levels to search a meal. They may even come into the scope of human eyesight. This explains the fact that they have been sighted now and then from the earth since 1942.
54．Which of the following best states the main idea of the passage?
A．The secret of nature can be completely explained.
B．Captain Nash may have been the first to see the lights in space.
C．Captain Nash saw twelve orange lights moving at a high speed.

　　On the night of July 6, 1943, a plane took off from an Air Force base in England to intercept(中途拦截) German fighters over the English Channel. Piloting the plane was Captain Thomas Nash. Looking westward, Nash saw twelve orange lights in a row, moving at a fantastic rate of speed. An experienced flyer, he had never seen anything like that. Thinking they might be a new German weapon, he decided to chase(追赶) it. But when he swung the plane around and headed directly for the lights, they vanished(消失).

　　Captain Nash may have been the first to see such orange lights but he wasn't the last. His experience was repeated many times by pilots during World War Ⅱ, both in Europe and the Far East.

　　What were they? No one knows for sure, but there is an interesting theory to account for them. According to this theory, the orange lights are space animals－animals specially adapted to lie in the upper atmosphere just as some creatures are adapted to life at the bottom of the sea.

　　These space animals, the theory says, live so far up in the atmosphere that they are not visible from earth. They feed partly on the air and partly on energy from sunlight. Being almost pure energy themselves, they can regulate their bodies to glow at night. During the day they become invisible.

　　Prior to World War Ⅱ, the theory continues, there was little radiated energy available on the earth's surface. Then came the development of rockets, atomic reactors, and hydroelectric plants. The space creatures are attracted to these sources of energy or food. At night when there is no energy from sunlight, they come down into the lower levels in search of a meal. They may even drift into the range of human eyesight. This explains the fact that they have been sighted periodically from the earth since 1943．

    On the night of July 6,1943, a plane took off from an Air Force base in England to intercept (截击) German fighters over the English Channel. Piloting the plane was Captain Thomas Nash. Looking westward, Nash saw twelve orange lights in a row, moving at a fantastic rate of speed. An old experienced flyer, he had never seen anything like them. Thinking they might be a new German weapon, he decided to give chase. But when he swung the plane around and headed directly for the lights, they disappeared.

Captain Nash may have been the first to see such orange lights but he wasn't the last. His experience was repeated many times by pilots during World WarⅡboth in Europe and the Far East. Pilots in the Korean War also reported seeing the strange lights.

What were they? No one knows for sure, but there is an interesting theory to account for them. According to this theory, the orange lights are space animals - animals specially adapted to life in the upper atmosphere just as some creatures are adapted to life at the bottom of the sea.

These space animals, the theory says, live so far up in the atmosphere that they are not visible from earth. They feed partly on the air and partly on energy from sunlight. Being almost pure energy themselves, they can adjust their bodies to glow (发光) at night. During the day they become invisible.

Before World War II, continues the theory, there was little radiated (发射的) energy available on the earth's surface. Then came the development of rockets, atomic reactors (核反应堆), and hydroelectric plants (水力发电厂). The space creatures are attracted to these sources of energy of food. At night when there is no energy from sunlight, they go down into the lower levels in search of a meal. They may even drift into the range of human eyesight. This explains the fact that they have been sighted regularly from the earth since 1943.
