白話解釋
be 動詞常常用來表示「是」、「在」、「怎麼樣」。最常看到的是 am / is / are。
主詞配對
I am
He / She / It is
You / We / They are
例如：I am happy. / She is a student. / They are in the classroom.

常見錯誤
錯誤 1：I 配 is
I is tired.
I am tired.
I 只能配 am。
錯誤 2：they 配 is
They is my friends.
They are my friends.
They 是複數，要用 are。
錯誤 3：be 動詞和一般動詞一起亂用
She is likes music.
She likes music.
如果用一般動詞 likes，就不要再加 is。
