he hasn't had breakfast yet.

he hasn't had breakfast yet. he hasn't had breakfast yet.句中的had能不能改用eat,如果可以的话有些什么区别? 改否定,例：he is still having breakfast.he hasn't had breakfast y Has he had his dinner yet?A.Yes,he hasn't B.No,he hasn't C.Y he hasn't decided it yet.请译出 he hasn't been caught yet he hasn't come yet是什么时态? Tim hasn't had breakfast .Jack hasn't had ,either.同义句 i don't know why he hasn't come yet. he hasn't had breakfast怎么理解?是根本没吃饭呢还是吃了但是还没吃完? We have been waiting____us,but he hasn't come yet. he hasn't moved to his new house yet.
