You have a fever?改为一般疑问句

可以改为Do you have a fever?为什么？

Answer 1

改为一般疑问句是：Do you have a fever？

要将陈述句变成一般疑问句，可以遵循下列步骤：
1.看句中有没有be动词（am、is、 are、 was、 were）、助动词（do、does、did、 have、 had）或情态动词（can、must、will、may等），如果有，将其提到句首，句末打上问号即可。
例：It was rainy yesterday.
→Was it rainy yesterday?
Tom's father can play the piano.
→Can Tom's father play the piano?
I have finished my homework.
→Have you finished your homework?
2.如果句中没有be动词、助动词或情态动词，则根据谓语动词的形式借助do的相应形式放在句首。
具体方法是：
①如果谓语动词是原形，则借do；
②如果谓语动词是一般现在时第三人称单数形式，则借does；
③如果谓语动词是过去式，则借did.
需要注意的是，借does或did后，原句的谓语动词要变回原形。
例：They go to school by bike.
→Do they go to school by bike?
Bill gets up at 6:30 every day.
→Does bill gets up at 6:30 every day?
The students saw a film yesterday.
→Did the students see a film yesterday?
二、陈述句变一般疑问句应注意的事项
陈述句变成一般疑问句除了遵循上述规则以外，还应注意下列几点：
1.如果陈述句中有第一人称，则变问句时最好要变为第二人称。
例：I usually have lunch at school.
→Do you usually have lunch at school?
My father is playing soccer.
→Is your father playing soccer?
2.如果陈述句中有some, 则变问句时往往要变成any 。
例： There is some water on the playground.
→Is there any water on the playground?
3.复合句变一般疑问句通常只变主句，从句不变。
例：I know he comes from Canada.
→Do you know he comes from Canada?
4．如果句中含有实义动词have且表示“有”时,除借do外，也可将其直接提到句首。
例：I have some friends in America.
→Have you any friends in America?/Do you have any friends in America?

Answer 2

这里的have是实意助动词，改为一般疑问句时需要用助动词来提问
