there be no need的几个用法问题!
①是there is no need doing sth 还是it is no need doing sth还是两者都可以用
②there is no need doing sth还是there is no need to do sth二者有什么区别

Answer 1

一、
只有:there is no need doing sth.句型.
应该是it is no use/good doing sth.没有it is no need doing sth.的句型!
二、
There is no need doing sth.
表示“干……没必要”.如：
There is no need going there.
去那里没必要.
There is no need to do sth.
表示“（客观上）没有必要做某事”.如：
There is no need to complicate matters.
没有必要使问题复杂化.
通常后者用得比较多
