    蒼蠅幾乎可以停在任何地方,豎直的玻璃,天花板……我們認為這是理所當然。可是,為什么蒼蠅能毫不費力地倒站在天花板上呢?想知道答案?那就趕緊來看下面這篇文章吧。

    Flies nearly can land on every place. When they land on the ceiling, they're upside down. We take it for granted, but think about this one...When the fly is heading for the ceiling, it's flying right side up. When it lands on the ceiling it is upside down. At some point along the way it has to flip over. But when? And Where? And How?

    Scientists dispelled the prevalent theory, that the fly performed a fighter pilot-like barrel roll just prior to landing, by capturing this momentous event on film.

    Freeze frames, from the high-speed cameras scientists used, proved that flies don't flip, but flop, as they land upon the ceiling. Prior to impact, the fly extends its forward legs over its head, makes contact, and uses the momentum it has gathered in flight to hoist the remainder of its body to the ceiling. Thus, the fly proves to be more of an acrobat, than of a fighter pilot practicing his maneuvers.

    Once the fly reunites all six feet on the ceiling, it keeps things dazzlingly exciting, by gracefully tiptoeing across the ceiling, securing itself by using sticky pads found under the two claws attached to each of its feet. It is because of these sticky pads and the hairs on the legs that the fly is such a carrier of disease germs.

    Did you know? The entire life of a housefly is spent within a few hundred feet of the area where it was born.

    hoist 提升,升起

    acrobat 雜技演員

    maneuvers 技術

    tiptoe 用腳尖走
