在一篇关于模特儿的文章中
Mr. Teller said that the only time he's porperly been star-struck
was meeting Will Ferrell. But for a man who regularly submits
himself to naked self-portraits in the most undignified positions,
Mr. Teller is unexpectedly prey to performance anxiety.
请问最后一行的 prey 在这里要怎么理解比较好呢？
另外
Recently Mr. Teller photographed the Bayern Munich football club.
He took his son on the trip to Germany so that he could meet his
sports heroes, and recalls them both lying in their respective beds
the night before unable to sleep: His son was wired with excitement,
he was anxious over whether he would get his shot.
倒数第二行的wire是什么意思呢？
