less和more的区别
more： 顾名思义显⽰更多
less： 由于more不能后退，就取more的反义词less加上后退功能
所以Linux⾥流传着这样⼀句话："less is more".
总结下more 和 less的区别:1. less可以按键盘上下⽅向键显⽰上下内容,more不能通过上下⽅向键控制显⽰，但是可以通过ctrl+B返回上⼀页。
2. less不必读整个⽂件，加载速度会⽐more更快
3. less退出后shell不会留下刚显⽰的内容,⽽more退出后会在shell上留下刚显⽰的内容
not...any more 和 not ...any longer有什么区别
not...any more表示次数不再继续；如：他哭了好几次,他不再哭了.He didn't cry any more.
而 not ...any longe表示时间不再继续.如：他等了很久,不能再等了.He couldn't wait any longer.
no longer / no more / not any longer / not any more 不再,再也不
--- no more / no longer 放在 be 动词、助动词、情态动词之后,行为动词之前.no more 多用来修饰具体动词；no longer多用来修饰某种具体状态动词．例如：
He no longer lived here.
He has no more trouble.
Bruce works in a company.He is no more a student.
--- 表示时间“一度,曾经”,强调以前的情况不再继续下去,once but not now.用no longer ,not any longer, not
any more.但no longer,not any longer多与持续性动词连用；not any more 多与终止性动词连用.
She used to study English,but she doesn’t study it any longer/any more.

Does Tom live here?No he no longer lives here.
He is no longer happy.
He doesn't come here any more.( 不用any longer)
