For the【C1】______month, mysterious falls of large chunks of ice(冰雹)【C2】______rained down on Spain and Italy. Juana Sanchez, a 70-year-old woman in Almeria, southern Spain, was knocked 【C3】______when she was struck on the shoulder by a falling ice chunk【C4】______she walked in a street【C5】______her home. On January 12, just about 200 miles away in Seville, a man narrowly【C6】______serious injury when a 9-pound ball of ice【C7】______into his car.【C8】______the evening of January 27 priests at the Salesian monastery in L'Aquila, Italy were startled by a loud crash.【C9】______the noise, they discovered a large chunk of ice on their yard,【C10】______intact. Upon examination, the block of ice【C11】______in at 2 kilograms and no source【C12】______. On the same day, about 100 miles northeast in Ancona, Italy, the local officials were called to investigate the report of a man【C13】______was struck【C14】______the head by all kilogram chunk of ice that apparently fell from the sky. Spain and Italy aren't the only European【C15】______getting attacked by huge ice blocks in January. On January 2 in Surrey, England(southwest of London), an East Indian man was walking through Newton Athletic Park when he【C16】______a strange whistling sound overhead. Seconds【C17】______,a large hunk of ice fell out of the clear blue sky and pounded into the soft ground, shattering over a 50-foot-wide area. The ice dug a hole of a foot deep and a foot in diameter. Even the shattered remains of the mystery ice were as large as tennis balls and were described as opaque【C18】______no unusual color or smell. Although eyewitnesses to the phenomenon report that they did not see anything in the sky that could account【C19】______the ice, scientists had to come up with a rationalization. Professor Jesus Martinez Frias, the geologist investigating the ice falls in Spain, told BBC News that the ice pieces had probably been【C20】______through sudden temperature drops in the stratosphere. This was the most likely explanation, he said, for the 'very unusual' phenomenon. 【C1】
