no more than和not more than
no more than的意思是"只不过"，not more than的意思是"不多于"。试比较：
There are no more than ten tickles left. 剩下不到十张票。 (有"票少"的含义)
The experiment was done by not more than 5 persons. 做这个试验的人不到五个。(没有"多"或"少"的含义，只是客观地说明数目)
This room is no bigger than that. 这个房间并不比那个大。 (有"两个房间都不大"的含义)
This room is not bigger than that one.这个房间不比那个大。 (没有"两个房间都不大或都不小"的含义)
[注]注意not …. Any more than或no more...than在下面句子中的用法。如：
They cannot do the impossible any more than we can.他们和我们同样不能做不可能的事情。
He is no more diligent than I am.他和我同样不勤奋
no less than和not 1ess than
no less than的意思是"不亚于"，not less than的意思是"不少于"。试比较：
There were no less than a thousand people at the meeting.
到会的有一千人之多。(有"到会人多"的含义)
There were not less than one thousand people at the meeting.
到会的至少有一千人。(没有"到会人多或人少"的含义)
This song is no less popular than that one.这首歌之受欢迎不亚于那首歌。(有"两首歌都受欢迎"的含义)
This song is not less popular than that one.这首歌受欢迎的程度不比那首差。(纯粹比较。不一定有"两首歌都受欢迎"的含义)
All the better和so much the better
这一类的说法都有"因此而更…"的含义。如：
If that is so，all the better.果真如此，那就更好。
If he will come，so much the better.如果他愿意来，那更好。
