prep30

30. The Sports Medicine Programs of the Olympic Training Center, a complex where final try outs are held for athletes representing the US in the Olympics, is geared toward enhancing athletes' performance and toward their preparation for international competition. C  E

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

正确答案为E，我选C，请教高手。总感觉prepare them 是非常别扭的

为什么不合理呢？不明白

从语法上理解比从逻辑意思上能容易一些。

C中的their preparation与athletes performance并列，成为enhance的宾语，这是错误的，因为原文要表达的是prepare与enhance并列。

C.) are geared to enhance
            athletes performance
            and
            their preparation
E.) are geared toward enhancing the performance of athletes and
            preparing them
