Then one day I read the following article from a magazine. A woman went to live with her husband in camp on the Mojave Desert during the war. She hated the place very much. The wind blew strongly, and there was sand everywhere. She could hardly breathe due to the heat. Finally, she wrote to her parents in Ohio. She told them that she couldnt stand it another minute and was coming home. Quickly the reply from her father came, but just two lines. “Two men looked out from prison (监狱). One saw the mud(泥土), the other saw stars.”The daughter did some real thinking with her heart. She decided to stay there. She made friends with the natives, learned to love the country.

In fact, lightning is electricity(电) formed high above the earth. A single flash of lightning which is 1.6 kilometers long has enough electricity to light one million lamps. Today, most tall buildings are protected by lightning rods(避雷针). These are metal rods which are placed on top of the highest, most exposed part of the building. A wire leads from the rod and is buried(埋) underground away from the building. This attracts the lightning and passes the lightning into the ground. In 1752, the American scientist, Benjamin Franklin, was the first to suggest that lightning is in fact electricity formed between the earth and clouds high above. In the same year, he also built the first lightning rod to protect buildings from being struck by lightning. Modern science has discovered that lightning is very strong and powerful. A lightning between a cloud and the earth may be as long as 13 kilometers, and travels at a speed of 30 million meters per second. Scientists have the opinion that there are about 2000 million flashes of lightning per year. In the United States alone, almost every day, it kills almost one person. Since lightning can be very dangerous and it has killed and hurt many people, it is important for us to follow safety measures and protect ourselves .The safest place to be in during an electrical storm is a closed car. Outside , one should go close to low ground for cover and not stop under a tree. Also one should stay out of water and away from metal fences. Inside a house people should keep away from open doorways and windows and not touch wires(电线) or metal things. Avoid using any electrical equipment such as hair driers, microwave ovens, or washers and so on.根据短文内容选择最佳答案。( )46. The underlined word “ mysteries” in the passage means “_”in Chinese.
