发布时间：2025-12-08 | 来源：互联网转载和整理

一般疑问句主要分为三类，第一，be动词类型；第二，情态动词can、may、should、must；第三，行为动词类型。

1.be动词类型（am/is/are）I am a student.（陈述句）I am not a student.（否定句）Are you a student？（一般疑问句）Yes，I am.（肯定回答）No，I am not.（否定回答）总结：含有be动词的句子，直接在be动词后加not变成否定句，is not=isn't，are not=aren't。将be动词直接提到句子主语前，注意将第一人称换成第二人称，即I换成you，we换成you。

2.情态动词类型（can/may/should/must）He can play basketball.（陈述句）He can not play basketball.（否定句）Can he play basketball？（一般疑问句）Yes，he can.（肯定回答）No，he can not.（否定回答）总结：含有情态动词的句子，变否定直接在情态动词后加not，变一般疑问句直接将情态动词提前。

3.行为动词类型I go to school by bike.（陈述句）I do not go to school by bike.（否定句）Do you go to school by bike？（一般疑问句）Yes，I do.（肯定回答）No，I do not.（否定回答）She goes to school by bike.（陈述句）She does not go to school by bike.（否定句）Does she go to school by bike？（一般疑问句）Yes，she does.（肯定回答）No，she does not.（否定回答）总结：行为动词变否定和一般疑问需要借助助动词do或者does，当主语是第三人称单数时，助动词用does。其他人称助动词用do。do not=don't，does not=doesn't。还有就是要记得把动词变为动词原型。
