把这一句，留给此刻的你
Their elegant shape, showy colours, and slow, sailing mode of flight, make them very attractive objects, and their numbers are so great that they form quite a feature in the physiognomy of the forest, compensating for the scarcity of flowers.
它们优雅的外形，艳丽的色彩，缓慢的航行方式，使它们成为非常有吸引力的对象，它们的数量是如此之多，它们形成了森林地貌的一个显著特征，弥补了花卉的稀少。
