用法
When constructions headed by one 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 sentence
One of every ten rotors was found defective.
Although the plural were is sometimes used in such sentences, an earlier survey found that the singular was preferred by 92 percent of the Usage Panel. · Constructions such as
one of those people who
pose a different problem. Most grammarians would argue that who should be followed by a plural verb in these sentences, as in He is one of those people who just don't take »noÆ for an answer. Their thinking is that the relative pronoun who refers to the plural noun people, not to one. They would extend the rule to constructions with inanimate nouns, as in
The sports car turned out to be one of the most successful products that were ever manufactured in this country.
However, constructions of this sort are often used with a singular verb even by the best writers. In an earlier survey, 42 percent of the Usage Panel accepted the use of the singular verb in such constructions. Note also that when the phrase containing one is introduced by the definite article, the verb in the relative clause must be singular: He is the only one of the students who has (not have ) already taken Latin. · Constructions using one or more or one or two always take a plural verb: One or more cars were parked in front of the house each day this week. One or two students from our department have won prizes. Note that when followed by a fraction, one ordinarily takes a plural verb: One and a half years have passed since I last saw her. The fraction rule has an exception in that amounts are sometimes treated as singular entities: One and a half cups is enough sugar. Note also that the plural rule does not apply to these one-plus-a-fraction constructions that are introduced by the indefinite article. These are always singular: A year and a half has passed since I last saw her.
