be动词引导的一般疑问句的书写规则如下:
一、基本结构
基本句型 - 将be动词(am/is/are)提前至句首,主语置于第二位,其余部分保持不变。 - 例如:
- I am a teacher. → Is he a teacher?
- She is lovely. → Are they lovely?
缩写形式
- 在一般现在时中,be动词后接主语时通常省略be动词,使用缩写形式:
- I am → I'm
- He is → He's
- They are → They're
二、人称变化规则
第一人称(I/we)→ 第二人称(you)
第二人称/第三人称(he/she/it)→ 保持不变
三、否定句的构成
在be动词后直接加 not,注意 am不可缩写:
I am → I'm not
He is → He's not
They are → They're not
四、示例应用
肯定回答
- Is this your book? → Yes, it is.
- She is a doctor. → Yes, she is.
否定回答
- Is he a student? → No, he isn't.
- The cat is sleeping. → No, the cat isn't.
五、注意事项
时态一致: be动词需与主语在人称和数上保持一致,例如: The children are playing → The child is not playing 缩写使用
通过以上规则,可灵活构建be动词引导的一般疑问句。
