less
1.严格地说，less指量（quantity）不指数（number），如可以说less money，less tea，less education，less traffic等，但不可说less yuan，less cups，less schools，less cars等，该把less改作fewer。说less than ten yuan是可以的，意思是“不满十元”，不作“不满十个一元”解。但事实上把less用作fewer解也有，如less people和less houses。
2.He is less clever than his brother和He is less clever than you think he is等句当然不错，但不及He is not so clever as his brother和He is not so clever as you think he is等普通。
3.注意I am not interested in her，still less（或much less）am I in love with her（我并不注意她，更不必说爱她了）里用am I，不用I am。
4.比较下面每组里的两句：
- It is not possible to finish the work in a week, still less(或much less) in three days.
It is impossible to finish the work in a week, still ore(或much more) in three days. - I was not allowed to see him,still less(或much less)to talk to him.
was forbidden to see him, still more(或much more)to talk to him.
上面四句是下面四句的省略式：
- It is not possible to finish the work in a week, still less (或 much less) is it possible to finish it in three days.
It is impossible to finish the work in a week, still more (或 much more) is it impossible to finish it in three days. - I was not allowed to see him,still less (或 much less) was Iallowed to talk to him.
I was forbidden to see him,still more (或 much more) was Iforbidden to talk to him.
在该用still more或much more的场合用still less或much less是英美人常有的错误。
5.关于more less，less more和less less，参见more 7
