细节理解题。由倒数第三段的"It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the grins and drag her away from the edge. That was where Lisa briefly regained consciousness"（很难把她抬起来。她刚出去。但他设法把她抬到了四英尺高的平台上，这样旁观者就可以抓住她的笑容，把她从边缘拖走。丽萨就是在那里短暂地恢复了意识.）可知,丽萨是在上了站台后恢复意识的。故选C。
