有读者问： 有这样一句话：
(1)None but an exceptionally strong man could have survived the accident.
为什么这里不用no one but而用none but?
none指人时相当于no one或nobody，这三个词语皆可后接but。none but如上述例（1），现将no one but和nobody but的用法举例如下：
(2)No one but me saw him.
(3)It hurt nobody but himself.
较之于no one和nobody, none显得文气一些，所以上述书面语例（1）用none较好。
