It is not necessary at all
It is unnecessary!
还是要看用在什么语境了。一般来说有这样两种：thereisnoneedto...这个表示没有必要干。。。后面一般接动词Itisnotnecessaryforsb.todosth.这个也是后面想到了补充
You don't have to...It is unnecessary...
necessary
There is no need to
It's unnecessary . It's not necessary .You don't have to (do that ).No need (to do that ).Don't bother.都可以表达没有必要。
最简练的其实就是its unnessary，老外也是这么说的
there is no need to (do sth) unnecessar都是
