gnat

When you write for a blog, your audience consists of internet users who have the attention span of a gnat.

当你写博客时，你的读者是网络用户组成的，他们的注意力范围就像一个小昆虫。

They, and we, and the smallest gnat in the grass are linked in the web of biodiversity - and the demise of one is a warning to all.

它们、我们、以及草丛中的小昆虫都联结在生物多样性这张网上，其中一种的消亡就是对全体的警告。
