SAT 难句分析.（简要的说就是几个句子不懂）
on the set,I met the two Asian American actors hired to play me:not only were they older than I,they were World Miss material.The available selection of Asian actors must have been as sparse as the roles available for them to play.（出自真题200801色section5）这几句话是什么意思?

答案

在拍摄现场,我见到了两位请来扮演我的美籍亚裔演员：她们不仅年纪比我大,而且简直是世界小姐的料儿.可供挑选的亚裔演员肯定比供他们出演的角色还要稀少.
