一、肯定句改一般疑问句的方法1.把be动词放在主语前（也就是句首），剩下的照抄，句号改成问号。
（I改成you，my改成your，some 改成any，）如：a:He is my father.改一般疑问句:Is he your father?b: I am fine.改一般疑问句:Are you fine?2.把情态单词can，shall， wil，must等放到句首，剩下的照抄，句号改成问号。（I改成you，my改成your，some 改成any）如：a:I can draw.改一般疑问句:Can you draw?b: I will come to the party.改一般疑问句:Will you come to the party?3.助动词Do/Does/Did放在句首，句号改成问号。其结构：助动词+ 主语 + 动词原形 + 其它？如：a:I like apples.改一般疑问句:Do you like apples?b: Amy reads books every evening.改一般疑问句:Does Amy read books every evening?c: Amy read books last night.改一般疑问句:Did Amy read books last night?注意：句首的第一个字母要大写，句尾标点应为“？”。
4、 就一般疑问句回答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。be动词或情态动词的一般疑问句的回答：肯定回答用Yes，主语+be\\情态动词.”，否定回答用“No，主语+be\\情态动词+not.”。be或情态动词和not可用缩写形式，主要有isn’t，aren’t，wasn’t，weren’t，can’t，mustn’t，needn’t等。如：Is he your father?肯定回答：Yes,he is.否定回No,he isn't.Can you speak English?肯定回答：Yes，I can.否定回答：No，I can’t.行为动词的一般疑问句的回答：肯定回答用“Yes, 主语+ do\\does.”，否定回答用“No, 主语+do\\does not.”。助动词也常用缩写形式，主要有don’t，doesn’t，didn’t等。如：Do you like apples?肯定回答：Yes,I do.否定回No,I don't.（二）肯定句改否定句的方法 ：
1. 在be动词后直接加not如：is not, are not,am notI am a girl. → I am not a girl.You are a student. →You are not a student.→You aren’t a student.2.在情态动词can，should， will等后加not如：can not, should not,will not；Li Lei can swim. → Li Lei cannot（ can't ）swim.He will go to the zoo if it rains tomorrow.→ He will not（won't）go to the zoo if itrains tomorrow.3.上述都没有的，在动词前加助动词否定形式don't/doesn't/didn'ta: 句中第一个动词是原形时，在其前加上don’t。如：I get up at six o'clock every day.→ I don't get up at six o'clock every day.b: 句中第一个动词是三单形式时，在其前加上doesn’t，原来的动词三单形式改为动词原形。如：Mr Wang works in a factory.→ Mr Wang doesn't work in a factory.C: 句中第一个动词是过去式时，在其前加上didn’t，原来的动词过去式改为动词原形。如：I watched TV last night.→I didn't watch TV last night.4、 some 改成any。（三）对划线部分提问对划线部分提问的程序：一找：找特殊疑问词二代：用特殊疑问词代替划线部分三移：把特殊疑问词移到句首四变：未划线部分变为一般疑问句★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：
1. 划线部分是“事或物”，特殊疑问词用what如: This is a book.---What is this?I often play football on Saturdays .---What do you often do on Saturdays ?2.划线部分是“人”，特殊疑问词用who如:He is my brother. ---Who is he ?３、划线部分是“地点”，特殊疑问词用where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?５、划线部分是“年龄”，特殊疑问词用how old如:I am twelve . ---How old are you?My father is thirty-three . ---How old is your father ?６、划线部分是“职业”，特殊疑问词用what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 ?11.划线部分是“交通方式”，特殊疑问词用how如 :I often go to school on foot.---How do you often go to school?12.划线部分是“原因”，特殊疑问词用"why"如：I like summer,because I like swimming.--Why do you like summer?
