I have just back from a h____ in America.

I have Just come back翻译成中文是什么哦? I have just came back from work.哪错了? I have just back from a h____ in America. I just come back from I just ccame back from i just come back form I have just come back from USA,这句为什么不用came? I have just come back from Tiawam ,the biggest of China.改为定语从句? I have just come back.是现在完成时吗?如果是,那come为什么不用过去分词? just用于现在完成时可以理解了,但是能不呢过用于过去式呢?我见有的答案说just用于完成时表示对现在的影响.但是还是没有根本说明到底just能不能用于过去式.比如：i have just received a letter fro I just came back from the airport i just want to be back是什么意思 I Just Got Back From Hell 歌词 我刚学完英语回来是不是 I have came back just learn English`~开玩笑用ENGLISH 怎么说呢? As long as we have love no matter how hard are worth!I just want you back to my world! just you want just i have Sorry i just have to go for a meetign back in about 30 minutes看下 这里的just是什么意思 和全句翻译 I would have just said
