10. It is widely asserted that none is equivalent to no one, and hence requires a singular verb and singular pronoun:
较普遍的认为是none 相当于 no one， 因此要求一个单数动词和单数代词与之相对应：
None of the prisoners was given his soup.
11. It is true that none is etymologically derived from the Old English word 3n, “one,” but the word has been used as both a singular and a plural noun from Old English onward. The plural use can be found in reputable sources such as the King James Bible, Dryden, and Burke; and H.W. Fowler described the traditional rule as “a mistake.” Either a singular or a plural verb is acceptably used in a sentence such as None of the conspirators has (or have ) been brought to trial. When none is modified by almost, however, it is difficult to avoid treating the word as a plural:
事实是这样的：none 根据词源学来自于古英语词汇 an “一，” 但是此词从古英语开始既被用作单数名词，又被用作复数名词形式。复数用法可以在规范的原始资料如詹姆士圣经、德莱顿以及伯克的作品中发现。H·W·福勒把传统的规则描述为“一个错误”。 无论是单数还是复数动词均可以被接受用于句子中，如所有的同谋者都未 （或者 have ) 被送审。 然而当none 被 almost 修饰时， 很难避免将此词当作复数：
Almost none of the officials were (not was ) interviewed by the committee.
几乎所有的官员都未（不是 was ) 被委员会接见。
12. None can only be plural in its use in sentences such as None but his most loyal supporters believe (not believes ) his story. See Usage Note at every, neither
None 在句中只能用复数形式， 如除了他的最忠实的支持者外，没有人相信 （不是 believes ) 他的故事 参见 every， neither
