肯定句：主语 +have/ has + done (过去分词 )+其它

一般疑问句： Have/ Has +主语 + done (过去分词 )+其它

Has he lived in Shenzhen for 4 years?

否定句 : 主语 +have/ has+ not + done (过去分词 )+其它

过去分词的构成方法如下:

1.一般情况下，直接在动词原形后面加–ed.

work---worked answer---answered obey---obeyed want---wanted

2.以不发音的 -e 结尾的动词只加–d.

Move ---moved hope ---hoped divide ---divided

3.字尾是辅音 +y 的动词。则将 y 改 i 加 ed.

study--- studied tidy--- tidied satisfy--- satisfied

4.以重读闭音节结尾的词，这些词的末尾只有一个辅音字母时，双写这个辅音字母，再加–ed. stop---stopped regret--- regretted drop---dropped
