过去分词

1 、规则动词:规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则:

(1)、一般动词,在词尾直接加“ ed ”。

work---worked---worked ,visit---visited---visited

(2)、以“ e ”结尾的动词,只在词尾加“ d ”。

live---lived---lived ,

(3)、以“辅音字母+ y ”结尾的动词,将 "y" 变为 "i" ,再加“ ed ”。

study---studied---studied ,cry---cried---cried

(4)、重读闭音节结尾,末尾只有一个辅音字母,先双写该辅音字母,再加“ ed ”。

stop---stopped---stopped , drop---dropped--dropped

2、不规则动词:

do---did---done go---went---gone come---came---come

have---had---had see---saw---seen be---was/were---been

句型转换:

1. He has already gone home.

___________________________________________ (否定句) ___________________________________________ (疑问句) ________________(肯定回答)________________(否定回答) 2. He has had lunch at home.
