一般疑问句
含有 be 动词
主语＋be(am/is/are)＋其他.
主语＋
be(am/is/are) not
＋其他.
Be(Am/Is/Are)
＋主语＋其他?
含有行为动词
主语＋
行为动词的原形/第三人称单数形式等（根据时态和主语）
＋其他.
主语＋
don't/doesn't/didn't＋行为动词原形（根据时态和主语）
＋其他.
Do/Does/Did
＋主语＋动词原形＋其他?
答案：2. (1) be(am/is/are) not
(2) Be(Am/Is/Are)
(3) 行为动词的原形/第三人称单数形式等（根据时态和主语）
(4) don't/doesn't/didn't＋行为动词原形（根据时态和主语）
(5) Do/Does/Did
解析：含有be动词的否定句是在be动词后加not；一般疑问句是将be动词提到句首。含有行为动词的肯定句中，主语是第三人称单数时动词用第三人称单数形式，其他人称用原形；否定句是在主语后加don't/doesn't/didn't，动词用原形；一般疑问句是在句首加Do/Does/Did，动词用原形。
