一、现在完成时的构成

肯定句：主语+have/ has + done (过去分词)+其它

He has lived in Shenzhen for 4 years.

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

He has not finished his homework.

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
