"Do you convert a declarative sentence to an interrogative sentence in English?"
把陈述句改为一般疑问句英语
例句：
1、I want to drive a bumper car. →Do you want to drive a bumper car? Yes, I do. No, I don’t.
2、He likes swimming.→Does he like swimming? Yes, he does. No, he doesn’t.
规则应遵循：一提，二改，三帮，四问号。
一提：
如果一个句子中含有be动词(am, is, are,)或情态动词can, must,的时候，变一般疑问句时，将他们提到句首。
例句：She is a new student. →Is she a new student?
二改：
改大小写，改人称
I—改为you，we---改为you，our---改为your，my----改为your，ours—改为yours.
例句：She is my friend. →Is she your friend?
肯定回答：Yes, she is. 否定回答：No, she isn’t.
三帮：
如果一个句子中没有be动词和情态动词，应该借助于三D来帮助。(do, does, did)且后面的动词用原形。
