帮忙分析个英语句子Mother is ailways ready to give everything she has

Mother is always ready to give everything she has to her children.
这句话写的挺好的!
妈妈总是准备着把它拥有的所有东西给她的孩子们.
这里的“he has”定语从句是作为everything的定语存在的!不是has to!
Mother has to give everything ready for her children.
这句话语句就是不对的!翻译也不通!
Mother always gives her chiladren everything she has .
有问题再找我

mother has to get everything ready for her children
