for ten years是什么时态？
如果没有上下文，时间状语是for ten years那么应该使用现在完成时态。
for加一段时间表示一个动作延续了一段时间，通常情况是现在完成时态。如：They have lived in this city for ten years.他们在这座城市居住了十年。
当然英语的时态不能只看时间状语，还要根据具体的句意来定。
it was before用什么时态？
句型
It was 时间段 before….“过了多久才(怎么样)……”
It was not long before….“不久，就……”
It will (not) be 时间段 before….“要过多久(不久)……才……”(before从句谓语动词要用一般时态)
例句：

It was five days before he came back. 五天后他才回来。
It will be half a year before you graduate from the school. 再过半年你才能毕业。
