(文中空格已用黑体标出,自己一个晚上敲出来的) 1A When Hitler decided to launch his invasion of Russia, he thought that nothing could stand in the way of his armies. Conquest, it seemed, was inevitable. He had surprise on his side, catching Stalin off his guard by launching his attack without a declaration of war. Hitler expected the campaign to last only a few months. In the event, it was to drag on for much longer. Like Napoleon before him, he had made a fatal mistake in failing to reckon with the severity of the Russian weather.

1B What flies without wings, hits without hands, and sees without eyes?The White Dragon, or avalanche. In Europe, this old riddle has been told since the Middle Ages, when the first mountain settlers braved cold winters and the dangerous waves of snow. The people also called it the White Death, sent by devils that rode on the white mass of snow.

Some of the earliest reports of avalanches come from Hannibal’s famous march across the Alps in 218 B.C. Crossing over the high mountains with troops and elephant trains to fight against the Roman armies, the general lost thousands of men and animals to disease, cold, and avalanches.

In 1800, Napoleon tried to crossed the Great St. Bernard Pass in the Alps with his army. Thousands of men were buried beneath 50 feet of snow. During World War I, men fighting in the Tyrolean Mountains lost more numbers to avalanches

than bullets - more than 40,000 passed away between 1915 and 1918.

The word "avalanche" comes from the French word for "descent," in reference to the descent of snow, ice, rocks, or earth that rushes down mountain slopes.
