“局内”，用英语怎么表达

“局外人”用英语表达可以是 outsider，同样”局内人“用英语表达可以是”insider“，还有一个习语”in the loop“，它可以译为”局内“，表示知道内幕或消息灵通，因此想表达是“局外的或毫不知情”，可以说“out of the loop”，例如：

These activists don't want to feel out of the loop.

这些活跃分子不想做局外人。

I didn't know Jack was leaving. I was out of the loop on that one.

我不知道杰克要走的事情，我对此事毫不知情。

loop 本来就有“圈”的意思，不过是具体的“圈”，例如：

The road went in a huge loop around the lake.

那条路环湖绕了一个大圈。

He tied a loop of rope around his arm.

他在手臂上用绳子系了一个圈。

但在习语 in the loop 中，loop 也是指“圈”，只不过是抽象的圈，指的是一群共同知道某些信息或参与诸如流言蜚语或阴谋之类的事情的人，例如：

Katy was always happy that her friends kept her in the loop with the latest gossip.

凯蒂总是很高兴她的朋友们让她知道最新的流言蜚语。

那是一次很好的会议，老板确保我们都参与其中。
