All of them are not here means some of them are not here.这句的ALL 和SOME为什么不可以是neither both
问题描述：
All of them are not here means some of them are not here.这句的ALL 和SOME为什么不可以是neither both
答
all， both， some后面接not都只能表示部分否定，而neither，nor， none都表示完全否定，改了意思就不对了
答
原句的意思也说不通啊，但是neither只能和nor连用。我觉得原句应该是
Not all of them are here means some of them are not here.
答
三者以上的否定用none,所以此句的全部否定用none.用all .not 只是部分否定.
both 只能指两者.而 “两个都不” 才用neither.
楼主的句子：All of them are not here means some of them are not here.正是解释all.not是部分否定的意思,即：All of them are not here 就是指some of them are not here
答
这是搭配问题，一般neither...nor...相搭配
