将英语陈述句转换为一般疑问句的方法可分为以下三类,根据谓语动词的类型选择相应规则:
一、谓语动词为be动词(am/is/are/was/were)
规则:
直接将be动词提到句首,句末改为问号。
示例 - 陈述句:She is a teacher.
一般疑问句: Is she a teacher?
- 陈述句:They were playing basketball.
一般疑问句: Were they playing basketball?
二、谓语动词为情态动词(can/may/must/will/would/should)
规则: 将情态动词提前至句首,句末改为问号。示例
- 陈述句:He can swim.
一般疑问句: Can he swim?
- 陈述句:They will go to school tomorrow.
一般疑问句: Will they go to school tomorrow?
三、谓语动词为行为动词(非be/情态动词)
规则: 在句首添加助动词do/does/did,然后将谓语动词还原为原形,句末加问号。 - 现在时
- 过去时:无论主语是谁,均使用did
示例 - 陈述句:He likes reading books.
一般疑问句: Does he like reading books?
- 陈述句:We had a great time last night.
一般疑问句: Did we have a great time last night?
四、注意事项
人称变化:
- 第一人称(I/we)变为第二人称(you)
- 第三人称单数(he/she/it)保持不变
其他变化:
- 将some改为any(如:There is a book → Are there any books?)
- 短语需保持原样(如:in the morning → in the morning)
通过以上规则,可系统地将陈述句转换为一般疑问句。
