一个 超难 的英语句子结构的分析

（1）Several weeks ago, our headmaster, Mr. Gaudi, told usthat our school had been chosen to compete on Smart Aleck—a game show which my best friend C arla and I both love. Carla has a good imagination, and I know a lot of history, so we thought we’d be good choice for the team.
（2）A few days later, Mr. Gaudi held a meeting with everyone interested in the show. He told us that Smart Aleck uses a five member team. He also said that three more people would be needed as backup（替补）. Unluckily four times that many students were at the meeting. So Mr. Gaudi said we would have a competition and the top eight scorers would become the team and the back up. Everybody agreed that this was a fair way to decide.
（3）Yesterday, all of the hopefuls went to the dining hall after school. We would have to decide the starting line-up（阵容）. Mr. Gaudi acted as the host. After a couple of hours, all the places on the team were set except one. Carla and I tied for that last position. We had to hold a one-on-one competition between the two of us. The winner would be on the team and the loser would be the backup.
（4）Midway through our two-person competition, I was starting to pull ahead. Then I saw the look on Carla’s face. I waited for a second and knew what I had to do. As much as I wanted to be on Smart Aleck, Carla wanted it even more. So, starting with my next question, I held back and let Carla win, just by a little bit. 【Her expression as she realized she would be on the show made up for my not being on the team.】 And since I will go as backup, I’ll still have the fun of seeing the show up close.
请分析【】里的句子结构，并解释as引导的是什么从句，做什么句子成分，如何翻译？详细点，谢谢

Answer 1

Her expression 【that Carla showed】 as she realized she would be on the show made up for my not being on the team.
请注意我加上去的【that Carla showed】，原句将这些省略了，这样的话，这句话就容易理解了。
主语：Her expression；
谓语：made up for；
宾语：my not being on the team；
【that Carla showed】 as she realized she would be on the show 是修饰Her expression的定粗宴语从句，而这个从句也是一个复合句，主句是Carla showed，而as she realized she would be on the show 是时间状语从句，所以，意思就是，当Carla意识到自己将能参赛时，所露出的（高兴的）神情。
整句话的意思是：当Carla意识到自己将能参赛掘毕时，脸上洋溢着兴奋的神情，看她这么高兴，也多少弥补了我自己落选的遗憾。岩散银

Answer 2

Her expression as she realized she would be on the show made up for my not being on the team.
照这样看，"as she realized she would be on the show made up for my not being on the team."作为“Her expression”的定语。
翻译：“她的表现就像她意识亏侍滚到她的参与演出销余（资格）是建立在我不予录入队伍之上的。”
但是这句话就不完整谈皮了，我感觉有问题，这样的话这句话就只有主语了，应该是缺少一个动词。
