521　What kind of helicopter? 哪一种直升飞机？

After years of practice, I learned to identify the different helicopters by their sound alone. Early one morning, I was awakened when one buzzed my barracks. I ran through the possibilities, but couldn't identify it. Intrigued by what kind of helicopter it could be, I sprinted to the window just in time to see the single engine, twin-bladed main rotor lawn mower come into view.

经过多年的练习，我能够光听声音就说出是哪一种直升机。一天清早，我被低空掠过的轰隆声吵醒。我把所有的可能性都排查一遍，仍然不能说出这是哪一种直升机。这激起我极大的好奇心，想看看这到底是哪一种。我全速冲到窗口，正好看到一部单引擎双刀主旋转割草机。
