One legacy of Madison Avenue's recent campaign to appeal to people fifty years old and over is the realization that as a person ages, their concerns change as well.
OG10th 84 One legacy of Madison Avenue's recent campaign to appeal to people fifty years old and over is the realization that as a person ages. their concerns change as well. (A) the realization that as a person ages, their (B) the realization that as people age, their (C) to realize that when a person ages, his or her (D) to realize that when people age, their (E) realizing that as people age, their 答案是B。。。为什么C不对啊。。。 那legacy xxxxx to xxxxxxx is to xxxxx也说得过去嘛。。。。感觉也很平行额~~~
我觉得还是要根据句子意思去判断吧 to realize是表示目的,表示One legacy of Madison Avenue's recent campaign is to realize... 但是我觉得这里关键是用了legacy, legacy是表示“遗产,馈赠”的意思,说明这件事情已经发生了,所以再用to realize有点不当
