辨析:no more than 与 not more than

1. no more than 表示“仅仅”、“只有”,强调少;而 not more than 表示“不多于”、“至多”。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。

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”;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”。如:

He is no morea writer than a painter. 他不是画家,也不是作家。

A whale is no more a fish than a horse is. 马不是鱼,鲸也不是鱼。

She is not more clever than he is. 她不如他聪明。
