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。

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。

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。
