【答案】 1.no more than 表示“仅仅”、“只有”(= only),强调少；而 not more than 表示“不多于”、“至多”(= at most).如：
He is no more than an ordinary English teacher.他只不过是个普通的英文老师.
He has no more than three children.他只有 3 个孩子.
He has not more than three children.他最多 3 个孩子(有或许还不到 3 个之意).
2.用于比较两件事物时,no more ...than 表示对两者都否定,意为“同……一样不”(＝neither ...nor)；而 not more ...than 指两者虽都具有某种特征,但程度不同,意为“不如”、“不及”(= not so ...as).如：
He is no more a writer than a painter.他不是画家,也不是作家(= He is neither a painter nor a writer).
A whale is no more a fish than a horse is.马不是鱼,鲸也不是鱼(=Neither a horse nor a whale is a fish).
She is not more clever than he is.她不如他聪明(= She is not so clever as he is).
