“hey mom”i said to my mother after telling he I had to have

“hey mom”i said to my mother after telling he I had to have my mom says i have to stop.这里有没有错?为什么 不是my mom said i had to I have to look after my mother 的同义句 "I have found my wallet."he said to me. 改为同义句：My mother was ill,so I had to look after my sister. I have to go to the hospital to look after my mother.(改为否定句) my mother was ill.i had to look after her at home(同义句) after i had had dinner ,i went to school 还是 after i have had A:Hey,Mom.Could I invite my friends to the party tomorrow ev I have to help my mother ()dinner "I have just heard from my mother,"Cathy said to Ben.怎么变为间接引 【改错】I (have to) (help) my mom (do) (dinner).
