she said to me "i came back an hour ago"变成间接引语是什么

He told me that he hadcomebackan hour before .为什么 不是 he told me that he had came back an hour before这里把came 过去时变为过去完成时， 过去完成时构成是 had+ 过去分词 。 come的过去分词是 come。 也就是说 come -came（过去式）- come （过去分词）.哦那 he didn't go to bed until he finished the homework 可是做完作业不应该是在去睡觉前边吗 那不应该是用过去完成时吗 he didn't go to bed until he had finished the homework这句话的意思是我做完作业才去睡觉的。做作业发生在睡觉之前所以 用过去完成时， 过去完成时表示发生在过去另一动作之前的动作。两种表达都是可以的。那 hewas upset at not being invited 为什么用not being invited呀介词at后 跟动名词， 由于 invite 和 he的关系是被动 doing的被动式 是beinginvited，这里 not being invited是动名词的否定式 。 没被邀请。
