3.疑问式结构：Have/Has+主语+动词的过去分词(+其他)?▶Have//youworked?我/你工作了吗?▶Hashe/she/itworked?他/她工作了吗?/它奏效了吗?▶Havewe/you/theyworked?我们/你们/他们工作了吗?ThinkandsharePresentation现在完成时的构成

4.简略回答结构：肯定回答:Yes，主语+have/has.

否定回答:No，主语+haven't/hasn't.▶Havewe/you/theyworked?我们/你们/他们工作了吗?

肯定:Yes,you/have.是的,你/我工作了。

否定:No,you/haven't.不，你/我没有。没有。ThinkandsharePresentation动词的过去分词的构成原则

1.规则动词的变化规则（1）大部分动词在词尾直接加-edclean→cleaned打扫help→helped帮助play→played玩耍（2）动词以不发音的字母e结尾时，直接加-dlike→liked喜欢live→lived居住love→loved喜爱（3）动词以“辅音字母+y”结尾时,变y为i再加-edtry→tried尝试study→studied学习marry→married结婚（4）动词为重读闭音节且词尾只有一个辅音字母时,须双写这个辅音字母再加-edplan→planned计划stop→stopped停止prefer→preferred更喜欢ThinkandsharePresentation动词的过去分词的构成原则

2.不规则动词的变化规则须根据不规则动词变化表专门记忆see-seen看到hearheard听到go-gone去fnd-found发现eat-eatenl吃beat-beat打败ThinkandsharePresentation现在完成时的标志
