你能说出这些漂亮的花的名字吗?(Can you name these pretty flowers?)
野生羽扇豆,有时被称为蓝帽豆,是最美丽的多年生开花植物之一。它们在早春或初夏开花,通常为蓝色、粉红色或紫色。当它们散布在草地和路边时,即使是最平凡的风景也能栩栩如生。野生羽扇豆也是卡纳蓝蝶用来保护其卵的唯一植物;当幼虫孵化时,它们爬上羽扇豆的台阶来吃新叶子。随着工业革命的到来,羽扇豆的数量急剧下降,这种花现在被认为是濒危的。
原文:
Wild lupine, sometimes called bluebonnet, is one of the most beautiful perennial flowering plants. They bloom in early spring or early summer, and are usually blue, pink, or purple. When spread across meadows and along roadsides, they can bring even the most mundane landscapes to life. Wild lupine is also the only plant used by the Karner blue butterfly to protect its eggs; when the larvae hatch, they crawl up the lupine steps to eat the new leaves. With the advent of the Industrial Revolution, lupine numbers declined drastically, and the flower is now considered endangered.
