The most famous is Braj Kachru's three-circle paradigm where countries are labeled inner circle, outer circle, and expanding circle.

最著名的是 Braj Kachru 的三圈范式，其中国家被标记为内圈、外圈和扩展圈。

After many similar hair-breadth escapes, we at last swiftly glided into what had just been one of the outer circles, but now crossed by random whales, all violently making for one centre.

经过多次类似的九死一生的奔逃，我们最终飞快滑进了刚刚还是外层圈子的地方，那里现在却有一些鲸鱼胡乱地交叉游动，全都急于到中心去。

The outer circle contains countries where English is used as an official language or a second language, typically countries that were colonized by the inner circle.

外圈包含以英语为官方语言或第二语言的国家，通常是被内圈殖民的国家。

It's only as external observers that we actually see the outer circle travel a circular path back to its starting point, giving us the one extra rotation.

只有当外部观察者看到外圈沿着一条圆形路径回到它的起点时，我们才会多转一圈。
