1、-陈述句变一般疑问句的规则-第 3 页陈述句变一般疑问句的规则（个人总结的） 福山中学 李婉将陈述句变为一般疑问句应遵循：一看，二调（或二借），三改。一看：看句子当中有没有be动词（am, is, are,was,were）或情态动词can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would)。二调：如果句子中有be动词（am, is, are,was,were）或情态动词can (could), may (might), must, need, ought to, dare
2、 (dared), shall (should), will (would)，变一般疑问句时,将他们调到句子开头。如：She is a new student. (改为一般疑问句)改：Is she a new student?二借：如果没有be动词或情态动词，那就要“借”。借什么呢？借助动词do, does, did.具体借哪个看句中谓语动词来决定，如果谓语动词是动词原形，那就借do,如果谓语动词是第三人称单数形式那就借 does, 如果谓语动词是一般过去式那就借did.借用来的这些词放在哪里呢？放在句子的开头。如： Tom sings well.(改为一般疑问句) 如： I went to
3、school by bus yesterday.改：Does Tom sing well? 改：Did you go to school by busyesterday？三改：改大小写，改人称，改回动词原形 I改为youmy-改为yoursome-改为 any we-改为you our-改为your ours改为yours. 借用了助动词 does, did后，原来的谓语动词要记得改回原形。因为是陈述句变为一般疑问句。句号自然要记得改为问号。如： She is my friend. (变为一般疑问句) 如：There are some apples in the desk. 改：Is she
4、your friend? 改：Are there any apples in the desk?备注：do 用于主语是第一人称或第三人称复数形式中。 does仅仅用于主语是第三人称单数形式中。 did 用于过去时态中。 其后的动词一律还原为原形练习：将下列句子变为一般疑问句1. She is my best friend.2. She lives in a small city.3. Tom is a good student.4. I can bounce the ball.5. They like apples very much.6. She studies English every night.7. The ruler is under the chair.8. That little girl can speak English.9.
