狀態連接動詞(Be verbs);表達狀態、關係、屬性、身份
Be 動詞基本上屬於「連接」動詞(Linking verb)，連接形容詞或名詞屬性:
She is nice.
She is a teacher.
這類動詞用於「靜態的」的連結，不牽涉到動作，只是用來描述狀態或狀態變化:
狀態:be、seems、appears
狀態改變:become、get、turn into
後面可以接表達外在或內在特徵的形容詞，如:
He is / seems / appears tall. → 外觀狀態
He is / seems / appears sad. → 心情狀態
His face turned green. → 外觀變化
He got / became angry. → 心情變化
也可以接名詞性的身份、關係:
e is a vegetarian. → 常態事實
She became / turned into a vegetarian. → 狀態改變
