听力原文：M: Did you make a reservation on the 9:00 flight? W: I thought you wanted to take the 8:00 one．It's too late to change now. Q: What happened to the woman? (15) A. She made a reservation for the 9:00 flight. B. She changed the reservation. C. She found they were late for the 8:00 flight. D. She misunderstood the man.

从对话来看：
男士问：“你预订 9:00 的航班了吗？”
女士说：“我以为你想乘 8:00 的航班，现在改变（预订）太晚了。”
这说明女士之前理解男士要坐 8:00 的航班，所以很可能订的是 8:00 的航班，而不是 9:00 的。男士的话表明他本来想要 9:00 的航班，所以是女士之前误解了他的意愿。

正确选项：D. She misunderstood the man.（她误解了男士的意思。）
