1、 在be动词后加not。如：is not ， are not ， am not
2、 在can，should， will等后加not。
如：can not， should not，will not；
3、 上述都没有的，在动词前加助动词否认形式don’t/doesn’t/didn’t。
如： i am a girl. → i am not a girl.
you are a student. →you are not a student.
this is tom’s bag， → this is not tom’s bag.→ this isn’t tom’s bag.
1、把be动词放在句首，剩下的照抄，(some 改成any，I改成you，my改成your)句点改成问号。
2、把can，shall， will等放到句首，剩下的照抄，(some 改成any，I改成you，my改成your)句点改成问号。
3、上述都没有的，在句首请助动词Do/Does/Did帮忙，剩下的照抄，(some 改成any，I改成you，my改成your)句点改成问号。
注意：句首的第一个字母要大写，句尾标点应为“？”。
I am in Class 6. →Are you in Class 6?
You are from America. →Are you from America?
It is an orange. →Is it an orange?
一般疑问句有两种回答，即：肯定回答和否定回答。其中，肯定回答用yes,否定回答用no。语句顺序为：Yes + 主语 + am /is/ are/was/were.|can.|do/does/did|; No + 主语+ am not/ isn’t/ aren’t
—Are you an English teacher?→Yes, I am. /No, I am not.
—Is that a bird? →Yes, it is./ No, it isn’t.
“就划线部分提问”是小学阶段英语学习的难点，但是一旦掌握了规律，就变得容易多了。小学英语对划线部分提问之答题口诀 ：
三倒：颠倒主谓语，但对主语或其定语提问时除外（some 改成any，I改成you，my改成your）
特殊疑问词的确定要根据划线内容而定,在小学阶段常出现的有以下几种：
如: This is a book.—What is this?
I often play football on Saturdays .—What do you often do on Saturdays ?
如:He is my brother. —Who is he ?
如:The box is on the desk.—Where is the box ?
④划线部分是“时间”，特殊疑问词用what time或when
如:It’s seven twenty . —What time is it ?
I usually get up at six . — When do you usually get up?
如:I am twelve . —How old are you?
My father is thirty-three . —How old is your father ?
如:Mike is a worker. —What is Mike ?
⑦划线部分是“颜色”，特殊疑问词用what colour
如: My hat is blue . —What colour is your hat？
⑧划线部分是“数量”，特殊疑问词用how many或how much
如:I can see five kites .—How many kites can you see ?
There is some milk in the glass. —How much milk is there in the glass ?
⑨划线部分是“多少钱”，特殊疑问词用how much
如:This pen is nine yuan . —How much is this pen ?
⑩划线部分是“形容词性物主代词或名词性物主代词”，特殊疑问词用whose
如:That is my book . —Whose book is that ?
The bag is yours. —Whose is the bag ?
17．问几点用What’s the time?或 What time is it?
