Explaining verb agreement in English

The user wants clarity on why "have" is singular in the first sentence and "be" is plural in the second. This happens because "none" can be either singular or plural depending on context. It agrees with meaning: singular when focusing on "not one" (e.g., no one), plural when referring to multiple people (like "friends"). The first sentence emphasizes no one coming, while the second refers to multiple people not being interested.

Understanding "none" agreement

The sentence "None of his friends has come" uses the singular "has" because it's emphasizing "not one friend." On the other hand, "None of his friends are interested" uses "are" because it focuses on the group. For countable nouns, you can choose singular or plural depending on emphasis, and both are accepted in informal contexts.

Considering subject-verb agreement

"None of his friends are interested" sounds more natural because "interest" as a subject complement usually pairs with plural. "None of his friends has come" uses singular because it's focusing on "not one," which is grammatically acceptable, though more formal. British English tends to prefer plural more often, while American English may favor singular in formal writing.

Clarifying subject-verb agreement

"None of the cake is left" (uncountable) vs. "None of the students were late" and "None of the students was late" (both acceptable). While plural is acceptable when referring to a group, singular sounds better when emphasizing "not one" (e.g., "None of his three friends has come"). Grammatical vs. notional agreement can add nuances depending on context.

Answer

因为主语 none 既可作单数,也可作复数。它后面接 “of + 复数可数名词” 时,动词的单复数取决于说话者侧重的含义:

  • 强调 “一个也没有”(= not one)→ 用单数
    None of his friends has come.
    Not one of his friends has come.(他一个朋友都没来。)

  • 强调 “没有任何人/不论谁都不……”(= not any)→ 用复数
    None of his friends are interested in the story.
    Not any of his friends are interested…(他的朋友们都不感兴趣。)

一些补充小规则:

  • 后面接不可数名词只用单数:None of the information is correct.
  • 口语里(尤其英式)复数更常见;较正式、或有具体数量限定时常用单数:
    None of his three friends has come.
  • 这两句换成另一种数也不算语法错,只是语气不同:
    None of his friends have come.(更口语自然)
    None of his friends is interested…(更书面,强调“一个也没有”)。
