Stepping into a pool of water is mon enough, but who could ever imagine stepping into a pool of fish? In February of 1974, Bill Tapp, an Australian farmer, saw a rain of fish that covered his farm. How surprised he must have been!
What caused this strange occurrence? This is a question that had long puzzled people who study fish. The answer turned out to be a bination of wind and storm.
When it is spring in the northern part of the world, it is fall in Australia. Throughout the autumn season, terrible storms arise and rains flood the land. The strong winds sweep over Australia like huge vacuum cleaners (吸尘器), collecting seaweed, pieces of wood, and even schools of fish. Strong winds may carry these bits of nature for many miles before vacuum dropping them on fields, houses, and astonished people.
Although they seem unusual, fish-falls occur frequently in Australia. When Bill Tapp was asked to describe the scene of fish, he remarked, “They look like millions of dead birds falling down.” His statement is not surprising. The wonders of the natural world are as mon as rain. Nature, with its infinite wonders, can create waterfalls that flow upward and fish that fall out of the sky.
