M:I know I promise to drive you to the airport next Thursday,but I’m afraid something has come up.They’ve called a special meeting at work.
W:No big deal.Karen said she 【was】 available as a back-up.
为何是was...他们是不是说下个周四的事吗...那不是应该是will be吗...如果说是因为karen在过去说了 那么said不就是过去式吗.

这里就要结合它的意思来理解了.后面有个back-up,它的意思是“备份”.
她说她可以是备份 (当时她确实可以这么说,i'm available as a back-up),和,她说她将是备份,意思不一样.所以,也可以是was.

我也不知道为什么是was，我觉得would be比较好。
