肯定 No one is born a failure.是对的.
语法规则如下:
No one is born是句子主要结构,a failure 属于主语补足语,和宾补的道理类似,主补和句子的主语存在逻辑主谓关系,
即,如果把主语的No one和a failure连成一句话肯定是成立的(No one [is] a failure.
类似的句子:
The stream water ran over my feet (cold).
Christian Anderson came back to his hometown (a prince of fairy tales)
The sun is burning (hot).
括号中的词都是主语补足语.
