Kick-off

I see.

So kick-off can also be a noun.

Kick的意思就是踢,因此kick-off原本描述的是足球运动中比赛开始时一方球员首先把球踢出去开球的动作。 现在我们可以用kick-off来表示开始或启动一项活动、程序或事件,并且加上连字符的kick-off还可以做名词。 What about the phrase get underway?

Get underway is slightly more formal than kick-off and it specifically means something has officially started and is now in progress.

So, for example, the academic year usually gets underway in September.

我们通常会用这个短语来描述一项重要或正式的活动开始了、开启了。 就比如一个新学期的开始或者一项重要工程的开工建设。 I think I've heard similar expressions in news reports and official announcements.
