no-one
1.说“没有人”用no-one或no one都可以，如No-one knows about it和No one knows about it。说“没有一个单独的…”该用no one，不该用no-one，如No one man can do it里的no one不可改作no-one。
2.不可说no-one of us，no-one of these，no-one of the books等，该把no-one改作none。
3.用了no-one不可用one，one's等词代它，如不可说No-one has yet availed oneself of this offer，该把oneself改作himself。
4.no-one属于单数形式。例如：No-one has yet applied for it. 把no-one当作复数是英美人常有的错误。
5.不可说No-one does not like it，该改作Every one likes it。
