Question

not less than和no less than的区别是什么

Answer 1

not less than和no less than属于比较结构，区别如下：
not less than中间放形容词和副词的原级，表示“不比……更”，即从程度上前者不差于后者的意思，如：
This singer doesn't sing less beautifully as that one.
这位歌手唱得好，不亚于那个歌手（至少一样好听，也许更好）。
He isn't less quick at figures than I.
他对数字反应快，不亚于我。（至少与我一样快）

no less than
中间放形容词和副词的原级，表示“与……一样”，如：
This singer sings no less beautifully as that one.
这位歌手和那个歌手唱得一样好听。
He is no less quick at figures than I.
他对数字的反应与我一样快。

no fewer than ,no less than,not fewer than,not less than 有什么区别

fewer是修饰可数名词的，less是修饰不可数名词的。
no fewer than、no less than的意思都是不少于。。。多达。。。不亚于。。。一般no fewer than只能修饰可数名词，而no less than 即能修饰可数也能修饰不可数的词。
例如：
Fresh air, no less than pure water and clean food, is essential to one's health.
新鲜空气不亚于纯净的水和干净的食物，对人们的健康是必不可少的。
In war no less han peace, food was an important influence .
在战时，粮食的影响重大，不亚于和平的时候。

No fewer than 40 missions divided between the two characters.
在两个角色之间不得少于40次任务。
Sports wears, no less than suits, are very much saleable.
运动服和西服套一样，非常畅销。

He owned no fewer than four handlooms and employed apprentices.
他有四台之多的手工织布机，还雇了几个学徒。

而not fewer than 不是固定用法，只是fewer than的否定形式~即为不少于的意思~~在句中根据意思灵活运用~

not less than
意思是：至少，不少于~ 例如：
It's not less than a mile to the station.
到火车站至少有一英里路。

执行董事会的法定人数，应不少于四个有投票权的成员。
