1、Some people may think that a damselfly is a dragonfly.In fact,a damselfly is thinner than a dragonfly.Its colour is not as bright as that of a dragonfly.While the dragonfly can fly very fast,even backwards,a damselfly flies slowly.
Q:This passage mainly tells us .
答
This passage mainly tells us ——How to distinguish the damselflies and dragonflies.(怎么分辨豆娘与蜻蜓)豆娘？damselfly就是豆娘为什么会翻译成豆娘？很滑稽，匪夷所思啊！豆娘，蜻蛉
蜻蛉俗称豆娘。蜻蜓目(Odonata)束翅亚目(Zygoptera)昆虫的通称，种类多，眼向两侧突出，翅具柄。翅狭窄，膜质，翅脉网状，静止时翅沿身体纵轴垂直地立于背上，而不像差翅亚目(Anisoptera) 的蜻蜓那样平展。体纤细，飞行力弱。为何俗称豆娘？常用名是豆娘啊。这个不用追根究底的，毕竟你问过为何马铃薯俗称土豆吗？
要是想知道，可以查资料。
不好意思QAQ我也不知道为何俗称豆娘...
