there be句型总结there is no need to do是否是There is + no + Noun + in doing something 中的唯一特例

Question

there is no use(in)doing
there is no point(in)doing
there is no need to do
还有什么与there is no need to do一样的？那这些没规律可言，要硬记吗？什么规律，直接说！！

Answer 1

不是！

与 there is 句型无关。而是由于 need point 和use 所决定的。

当然有了，随便想起两个了
there is no reason to do sth
there is no enough time to do sth

一开始当然要硬记。但记多了后 就感觉出规律了。
呵呵，名词 use、point 后接动名词场合多。另外要凭 语感。

总之和theie be 结构没什么必然联系。
例如 I have no reason to do sth
It is useless in doing something
It is reasonable to do sth

Answer 2

there is no need to do 此处need名词，需要 to do不定式作后置定语
there is no use/point 中use point也是名字，不过是用的动词的现在分词作定语 修饰use point
