when do one have to use, HAVE DONE WITH , thanks
First, you never have to use it, but you may often choose to use it. There are at least two ways:
1. Have done with it is an idiom. It's about completing an unpleasant task. Other idioms meaning the same thing are:
Get it over with.
Be finished with it.
Wash my my/his/her/their hands of it.
Get it done and behind you/her/him/them.
Digging the grave is a big job, so let's have done with it.
I'm not looking forward to firing her, so I might as well have done with it.
2. It's also part of an idiomatic verb form:
What have you done with it? = Where did you put it?
What has she done with her hair? = Her new hair-do is alarming.
Again, if you're having trouble with this, ask again later. This might be higher level English than you're ready for now.
