Winters in the northern United States are cold and snowy. Sometimes, the snows come with extremely (极端地) strong winds. These snowstorms are called blizzards.

The dictionary Etymology Online says blizzard came to mean a heavy snow storm during the late 1800s. Before then, the word blizzard had nothing to do with snow. It had several other meanings. One was a sharp blow, like hitting a ball with a stick. Another meaning was a gun shot. And blizzard was also defined(下定义) as a most extreme statement or event.

These days, we do not use blizzard to mean any of those things. Blizzard is only used to mean an extreme snow storm. The first such use was in 1870. An especially heavy snowstorm hit the state of Iowa. This storm was the worst winter storm in a long time. A newspaper editor in a small Iowa town called the terrible storm a blizzard.

Much like a blizzard, the use of the word blew across the country over the next few years. Just as snow sticks to the ground, the word blizzard stuck as meaning any really bad winter storm.

Snow changes the world around us. When snow is falling, the world seems very soft, peaceful and quiet. But blizzards are different. They can be dangerous. Blizzards create white-out conditions. A white-out is when snow is falling fast and winds drive the snow so much that it is impossible to see.

29. Before the late 1800s, the word blizzard had these meanings EXCEPT .

A. a sharp blow B. an extreme snow storm C. a gun shot D. a most extreme statement or event
