求解一下
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.
(C) are geared to enhance athletes' performance and their preparation
(E) are geared toward enhancing the performance of athletes and preparing them
答案是E,C的解释是to enhance和their preparation不平行,这个可以理解,想问的是为什么不能把athletes' performance和their preparation看作平行结构呢 |
