(A) one’s own work, always one’s own work: not thinking about it, not assessing it, but simply doing it

(B) always work; because you don’t think about it or assess it, you just do it

(C) always one’s own work: not thinking about or assessing it, but simply to do it

(D) not to think or assess, but doing one’s own work（A）

(E) neither to think about one’s own work nor to assess it, it is always simply doing it

请问为什么是A而不是E? 求助

将 E 简化一下：

两个完整句子不能用逗号连接。
