When constructions headed byone appear as the subject of a sentence or relative clause, there may be a question as to whether the verb should be singular or plural.Such a construction is exemplified in the sentenceOne of every ten rotors was found defective. Although the pluralwere is sometimes used in such sentences, an earlier survey found that the singular was preferred by a large majority of the Usage Panel. ·Another problem is raised by constructions such asone of those people who or its variants. In the sentenceThe defeat turned out to be one of the most costly blows that were ever inflicted on our forces, most grammarians would hold that the pluralwere is correct, in as much as the subject of the verb is the plural nounblows. However, constructions of this sort are often used with a singular verb even by the best writers.Note also that when the phrase containingone is introduced by the definite article, the verb in the relative clause must be singular:
当以one 开头的结构作为一个句子或关系从句的主语出现时， 就出现动词用单数还是复数的问题，如用在句子每十个转子中有一个为次品 中的这种结构。 虽然复数were 有时用在这种句子中， 但在一次早期的调查发现用法专题使用小组的大部分成员更倾向于用单数。另一个问题是由象one of those people who 这样的结构及其变化引起的。 在句子The defeat turned out to be one of the most costly blows that were ever inflicted on our forces, 中, 大多数语法学家主张用复数were 是正确的， 以及主要是由于动词的主语是复数名词blow 所致。 然而，这种结构常与单数动词连用，甚至被很有声望的作家采用。也要注意当包含one 的短语被定冠词限制时， 相关的从句中的动词一定要用单数：
例句：
He is the only one of the students who has (not have ) already taken Latin. See Usage Note at he
他是这些学生中唯一一个（不用 have ) 曾学过拉丁语的人。 参见 he
