If something is long-running, it has been going on for a long time — and quite often it is still going. A long-running television show is one that has been on year after year, not a series that lasted one season. News writers like the word for things that will not end: a long-running dispute, a long-running court case, a long-running investigation.

If something如果某個東西 is long-running， it它 for a long time已經很長一段時間 has been going on一直在進行—— and quite often而且常常 it is still going現在還在進行。 A long-running television show長年播出的電視節目 is one就是 year after year一年又一年 that has been on一直在播的那種， not不是 that lasted one season只演了一季的 a series影集。 News writers寫新聞的人 for things that will not end對那些一直結束不了的事 like喜歡用 the word這個字： a long-running dispute拖了很久的爭議、 a long-running court case纏訟多年的官司、 a long-running investigation進行多年的調查。

The picture is of something in motion that has kept moving across months or years, not of something that merely sat there. That is why we say a long-running programme or a long-running battle more readily than a long-running person. A person is not usually long-running; a show, a conflict, or a campaign is.

The picture這個字的畫面 is是 something in motion一個在動的東西， across months or years跨過幾個月、幾年 that has kept moving一直動個不停， not something不是 that merely sat there只是靜靜擺在那裡的東西。 That is why所以 we我們 say說 a long-running programme長年的節目 or a long-running battle或長年的纏鬥， than a long-running person比起說長年的「人」 more readily要順口得多。 A person人 is not usually通常不會是 long-running； a show節目、 a conflict衝突 or a campaign或一場長期行動 is才會是。

It sounds a little more formal than just very long, and you will meet it a lot in newspapers. A show that has already finished can still be called long-running if it ran for years while it was on.

It它 than just very long比起只說 very long sounds a little more formal聽起來正式一點， and而且 in newspapers在報紙上 you will meet it a lot你會常常遇到它。 that has already finished已經完結的 A show節目， if如果 while it was on它還在播的那些年 it ran for years一演就是好幾年， can still be called仍然可以稱作 long-running。
