no better than 和not better than 的区别

Question

如题所述

Answer 1

not +比较级+than 不比…好（或坏）,即两者在某方面不相上下.如：John is not better than Tom. 约翰并不比汤姆好.He is not healthier than his friend. 他并不比他的朋友更健康.
“no+比较级+than ”结构表示该形容词或副词的相反含义,意思是“与…一样不…”如：no better than意义上相当于as bad as, no wiser than意义上相当于as stupid as , no richer than相当于as poor as, no bigger than相当于as small as.
The machine is no better than his friends.这台机器和那台一样糟.
前者表示我没你好，但我们俩都是好人。后者表示我和你一样坏，意思是我俩都是坏人。

Answer 2

not better than 是客观的评价,比如：your car is not better than mine.意思是你的车没我的好.
no better than 是主观评价,比如：your car is no better than mine.意思是你的车还没我的好呢（指两个人的车都不好）
