①no more than的意思是“仅仅”“只有”“最多不超过”,强调少。如:
This test takes no more than five minutes.这项测验只要5分钟。。
②not more than为more than(多于)的否定式,其意为“不多于,不超过如:Not more than10guests came to her party.来参加她派对的客人不超过十人。
比较:She has no more than three cats.她只有3只猫。(强调少)
She has not more than three cats.她至多有3只猫。(也许不到3顶帽子)
③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)。
简单来说,not more…than表示“前不如后”,而no more than如:
This book is not more interesting than that one.
这本书不如那本有趣。
This book is no more interesting than that one.
两本书都不有趣。
3,less than与no less than
