单亲家庭的男孩婚姻观:fix X in one's mind

fix X in one's mind fix one`s eyes on什么意思? in one's quest是什么意思 in one's way是什么意思？ hold ceremony in one's honor in one's spare time=in one's free time? She's definitely one in a million, or one in a billion on one's behalf和in one's behalf有区别吗？ 在某人家应说in one's 还是at one's "in one's way to" or"on one's wayto"?
