Person 后面用 is 还是 are?

英语主谓一致规则详解

在英语学习中,很多初学者会疑惑:“person” 后面到底该用 “is” 还是 “are”? 其实,答案取决于主语是单数还是复数。

1. 单数主语:person → is

“Person” 是一个可数名词,表示“一个人”。当主语是单数(如 a person, this person, every person)时,动词要用第三人称单数形式 is

✅ A person is waiting outside.

✅ Every person is responsible for their actions.

✅ This person is my teacher.

2. 复数主语:people / persons → are

“Person” 的复数形式通常是 people(更常用),正式或法律语境中也可用 persons。此时动词用 are

✅ These people are from Canada.

✅ Several persons are under investigation. (正式用法)

✅ All the people in the room are smiling.

3. 常见误区提醒

❌ 错误:A person are here.
✅ 正确:A person is here.

记住:“person” 本身是单数,除非明确变为复数(people/persons),否则永远搭配 is

总结

Person → is(单数)
People / Persons → are(复数)

掌握这一点,就能避免主谓不一致的常见错误,让你的英语表达更准确、更地道!
