2. more than 与less than：前者“(指数量)多于”、“不只是”、“非常”等，后者表示“少于”、“比……少”。如：
I’ve known him for more than 10 years. 我已认识他10多年了。
He is more than a father to her. 他待她胜过父亲。
She was more than kind to us. 她对我们很友好。
It cost me less than 10 pounds. 我买它没要上10英镑。

3. more …than 与 less…than：前者表示“比……多，比……更”，后者表示“比……少，不如……”。如：
He has more books than me. 他的书比我多。
He is more careful than the others. 他比其他人更仔细。
I got less money than the others did. 我比别人得到的钱少。
注：两者均可表示“与其……不如”，但词序不同。如：(from http://yingyu.chazidian.com)
He is less a teacher than an expert. / He is more an expert than a teacher. / He is not so much a teacher as an expert. 与其说他是老师，不如说他是专家。
4. “no+比较级+than”结构：这类结构的实际意思是对待比较的两个对象进行否定，相当于该原级形容词或副词使用as…as结构的意思。如no better than = as bad as，意为“与……一样不好”，no faster than = as slow as，意为“与……一样不快”，no taller than = as short as，意为“与……一样不高”等。
5. no more than与not more than：两者均可表示数量，前者表示“仅仅”、“只有”(= only)，强调少；而后者表示“不多于”、“至多”(= at most)。如：
It is no more than five miles to the station. 去车站只有5英里。
It is not more than five miles to the station. 去车站最多5英里。(from http://yingyu.chazidian.com)
6. no more…than与not more…than：前者用于否定两者，意为“同……一样不”(=neither ... nor)；而后者只强调两者的程度不同，意为“不如”、“不及”(= not so ... as)。如：
He’s no more able to read Spanish than I am. 他和我都读不懂西班牙语。（=Neither he nor I am not read Spanish.）
She is not more clever than he is.  她不如他聪明。（= She is not so clever as he is.）
