there is no point和there is no sense有什么区别?

there is no point There is no point doing there is no way 和 there is no need 在用法上有什么区别? Because ,there is no sense of security . there is no sense in doing sth 请问:There is no book.与There are no books.有什么区别?换言之,No book和 N There is no water.和There is not water.有什么区别 there is no use/point/sense in doing sth.请问其中的in分别能不能省略? There is no point doing 啥意思? there is no point 嘛意思 造句 there is no doubt ,与there is no wonder 有什么区别 there is no和there are 有什么区别?后面加复数还是单数?
