am・is・are

be 動詞：am、is、are

The verb be: am, is, are — English grammar, junior high

接續

說明

be 動詞是「是、在」，跟著主詞變化：I am a student.（我是學生。）She is in the library.（她在圖書館。）否定在後面加 not，疑問句把 be 動詞移到句首：Are you OK?

be means “is / are” and changes with the subject: I am a student, She is in the library. Add not after it for the negative, and put it first for a question: Are you OK?

注意事項

• 複數主詞（包含 A and B）用 are：Tom and I are friends.
  Plural subjects, including A and B, take are: Tom and I are friends.
• 否定縮寫：isn't、aren't，但 am not 沒有縮寫成 amn't。
  Negative short forms: isn't, aren't — but there's no amn't.

常見錯誤

• ✗ My brother are tall.
  ✓ My brother is tall.
  my brother 是單數，用 is。
  my brother is singular: is.
• ✗ I tired.
  ✓ I am tired.
  形容詞前面不能少了 be 動詞。
  You can't leave out be before an adjective.
