Ninety percent of the labor force in the United States is going to be white collar.
请问这里用 is 对吗？我认为应改为 are。
当单个词 per cent 或 percent of + 名词充当主语时, 谓语动词是采用单数还是采用复数, 完全取决于有关名词的单复数形式。ninety percent of the labor force 所涉及的名词 the labor force 是单数, 因此上句中的 is going to 是正确的。相反, 当涉及的名词是复数时, 则必须采用复数动词:
- Five(one) per cent of the samples were substandard. 百分之五(一)的样品不符合
标准。
