问题描述:

That year's Olympic were special because the games were coming back to the country where they started.
在这句话中,为什么要用 were coming back 可否用came back?

用were coming back 是表示一种状态(过去进行时),不能用came back,came back表示这个动作已经完成。

奥运会是过去正在进行的,所以不能。

be coming back 用进行时表将来
对于当年来说 奥运会 将要回到发源地举行
也就是对于这句话中的情景奥运会还没举行

不能换的
按照语境,很可能是were coming back是当作过去将来时来用,不是当作过去时,强调将要回到起源地,只是前面用了过去式,后面也用过去进行时表示过去将来时,
你可以把过去式都换成将来时就清楚多了
