7、i再加ed（此类动词较少）study studied carry carried worry worried （play、stay） 双写最后一个字母（此类动词较少）如stopped 、不规则动词（此类词并无规则，须熟记）小学阶段要记住以下动词的原形和过去式：sing sang , eat ate , see saw , have had , do did , go went , take took , buy bought , get got , read read ,fly flew , am/is was , are were , say said , leave left , swim

He does not (doesnt) work in a hospital. There are not (arent) four fans in our classroom. He will not (wont) eat lunch at 12:00. I d

11、id not (didnt) watch TV yesterday evening. 注意 小结：否定句主要是在肯定句的基础上加上了否定词 “not”。（1）有动词be的句子：:可缩写成“isnt，arent”， am not 。（2）没有动词be的句子：助动词do，does，did加not，可缩写为“dont , doesnt , didnt ）。这三个助动词要根据人称和时态来选择。 （三）、一般疑问句：是指询问事实的句子，此类句子必须用“yes”，或“no”来回答。如：Are you a student?

13、ill. / No, I will not(wont).Are they swimming? Yes, they are. / No, they arent.Did you watch TV yesterday evening? Yes, I did. / No, I didnt.注意 小结：一般疑问句是在肯定句的基础上，把动词be调到首位，其他照写，末尾标点符号变成问号即可。没有动词be的句子则要在句首加上一个助动词（do，does，did）再把紧跟在后面的动词变回原形，末尾标点符号变成问号即可。这三个助动词也要根据人称和时态来选择般。一般疑问句有个重要的原则就是问和答要一致，即怎么问就怎么

14、答。同时注意人称的变化。第一人称要变为第二人称，如：I am listening to music.(改为否定句)- Are you listening to music?（四）、特殊疑问句：以特殊疑问词（what , where , who , which , when , whose , why , how等）开头引导的句子。此类句子应该问什么就答什么，不能用“yes 、no”来回答。如：What is this?
