"enhance preparation" is unidiomatic ba

39. (26509-!-item-!-188;#058&002648)

The Sports Medicine Programs of the Olympic Training Center, a complex where final tryouts are held for athletes representing the United States in the Olympics, is geared toward enhancing athletes' performance and toward their preparation for international competition.

(A) is geared toward enhancing athletes' performance and toward their preparation
(B) is geared to enhance the performance of athletes and to prepare them
(C) are geared to enhance athletes' performance and their preparation
(D) are geared toward the enhancement of athletes' performance and toward preparing them
(E) are geared toward enhancing the performance of athletes and preparing them  

答案E关于C和E的纠结
C的平行是performance & preparation.
E的平行是enhancing & preparing


就平行本身而言，二者都有平行结构，不同的只是逻辑意思的不同。
C：增强（表现水平）和（对比赛的准备）
E：（增强比赛）和（为比赛做准备）
我个人认为是C比较好，因为E中，如果把preparing和enhancing平行，句子变成：
programs are geared toward enhancing... and preparing them for international competition.
我的问题是，prepare的主语是谁？如果是指programs的话，可以说programs prepare them（athletes）to...吗？ 这句子不通吧？
