英语翻译
You have probably heard the expression,“It’s raining cats and dogs outside．”That means that it's raining very hard I not that real cats and dogs are falling from the sky ．However,one day in June,1882,it really did rain frogs over Dubuque,Iowa．The frogs began falling along with hailstones(冰雹)during a terible storm．
Hail is formed when drops of rainwater are caught by heavy winds and are carried high up into the air．There the raindrops become frozen．Many drops may freeze together to form balls of ice；these ice balls,or hailstones,then lose to earth．
During the storm in Dubuque,the strong winds lifted small frogs from nearby ponds(池塘)by the air along with raindrops．When some of these frogs became covered with ice,both hailstones and“frog-stones”fell onto the ground．
