Proper Adjective 問題

第一句錯，第二句正確。

如果簡單現在式或過去式句子中有動詞，轉做問題時要在主詞 (subject) 前加上 Do, Does, 或 Did，而動詞則無須再加 s 或 過去式。
例句：
He swims every day.
Does he swim every day?

She visited her uncle yesterday.
Did she visit her uncle yesterday?

如果句中動詞是 verb to be (is, are, am, was, were)，轉做問題時將 verb to be 放於主詞前便可。
例句：
His father is a fireman.
Is his father a fireman?

如果句中有助動詞 (can, could, may, might, will, would, shall, should)，轉做問題時將便將助動詞置於主詞前。
例句：
John can swim 50 metres.
Can John swim 50 metres?

你句子的動詞 is 是 linking verb一種, be, 不是 action verb. 無須再加 Do, Does 或Did
例如: He is a teacher. Is he a teacher?
He is kind. Is he kind?

He speaks English. Does he speak English? (action verb)
小心: He has a car. Does he have a car?

小心 continuous tense
He is playing. Is he playing?

兩句哪句好? WHY?
只有 B 好，因為 A 是錯的句子。

B
`.`A double左句子的verb, &B is less complicated
