1、Not better than 与 no better than 的区别在形容词比较级前面可以加上 not 或 no ，但两者表示的意义不同。“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 st
2、upid 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。Jim is no more careful than you are.吉姆和你一样不仔细。not better than 与 no better than 所表达的意思是完全不同的。A is not better than B 只是简单地进行程度上的比较，一般可以为“A 不比 B 好（强）”。至于 B 本身是好（强）还是不好（差），这样的句子本身
3、是反映不出来的。A is no better than B 与 A is not better than B 不同，它并不对 A 和 B 进行程度上的比较，而是用来着重表达 A 和 B 都很坏（差）这样一种口气的。这是 no +形容词比较级+than 的用法.表示的含义是:和.和一样不.(两者都表示否定);如:This one is bad ; the other one is no better than it .翻译一下就是:这个不好,另一个也不比它强.类似的还有 no more than 等;eg:Jack is no more deligent than Tom:Jack 不勤奋 To
4、m 也不勤奋例题一-did badly in the examination . How about you ?- I did you .A . not as well as B . no better than C. no worse than D . not better than 思路分析选 B.这是个比较典型的比较级的否定用法。我这次考得很差。你呢？我不见得比你好。前面一个人说他考得很差，badly，所以根据语境，第二个人会说自己考得不会比第一个好。no better than 不会比你好，至少和你一样差。例题二-Does Tom do his new job well? -_ his
5、 old job. How stupid! I think there is no hope for him. A. No better than. B. Not better than. C. Not so well as. D. No as well as 思路分析A。no better than：表示“和一样；实际等于”，如：He is no better than a beggar. 他实际上等于一个乞丐。The invalid is no better than he was yesterday. 病人的情况和昨天一样。He has no better a say in the matter than I have.他和我一样在这件事上没有发言权。
