a cliffhanger

I did.There were several cliffhangers at the race.

Martha : Especially when the Number 6 racer took a sudden turn.

Sandra : Yeah. My heart almost missed a beating .It was indeed breathtaking.

Note:

cliff的意思是"悬崖"．hanger指"悬挂着东西"．我们知道，挂在悬崖上的东西总使人有一种提心吊胆的感觉，所以，a cliffhanger就常用来喻指"扣人心弦的东西"．

e.g.

The NBA final of 1998 was a cliffhanger.Michael Jordan saved Chicago Bull at the last minute and helped the team win the sixth championship.

1998的NBA是一场扣人心弦的比赛．迈克儿．乔丹在最后一分钟拯救了芝加哥公牛队，并帮助次队获得了第六次冠军．
