将陈述句改为一般疑问句的基本步骤如下:
一、根据动词类型调整语序
含be动词(am/is/are/was/were) 将be动词提前至句首,主语随后移动,句号改为问号。 例:
- 陈述句:She is a student.
- 一般疑问句: Is she a student?
含情态动词(can/may/must等)
将情态动词提前至句首,主语后移,句号改为问号。 例:
- 陈述句:He can drive a car.
- 一般疑问句: Can he drive a car?
含实意动词(如do/does)
在句首添加助动词do/does(第三人称单数用does),然后将主语后移,句号改为问号。 例:
- 陈述句:They learn English every day.
- 一般疑问句: Do they learn English every day?
二、人称和数的变化
主谓一致: 第一人称(I)变为第二人称(you),第二人称变为第一人称,第三人称单数(he/she/it)保持不变,复数主语(they)无需变化。 代词替换
I → you
we → you
my → your
our → your
三、特殊注意事项
过去时态:若动词为过去式(如bought),需先使用助动词did将其还原为原形,再调整语序。 例:
陈述句:She bought me a phone.
一般疑问句: Did she buy me a phone?
缩写形式:
否定回答中,can't可缩写为can't,mustn't保持原形。
四、示例汇总
| 陈述句 | 一般疑问句 | 回答示例 |
|--------|--------------|----------|
| This is a book. | Is this a book? | Yes, it is. / No, it isn't. |
| He can swim. | Can he swim? | Yes, he can. / No, he can't. |
| They have finished the task. | Have they finished the task? | Yes, they have. / No, they haven't. |
通过以上步骤,可系统地将陈述句转换为一般疑问句。若需进一步强调,可加入否定词(如don't)或使用疑问代词(如what, where)优化表达。
