beat one's head against a wall什么意思啊

beat one's head against a wall什么意思啊 请问是beat one's head 还是knock noe's head? beat one's head against the wall意为徒劳无益；求造句 shake one’s head beat over the head和get back 不是get one's back up,是get back up hold one's head up get one's head around 英语翻译：talk over one's head. shake one's head.英汉互译 to laugh one's head off shake one's head的缩写 cut off one's head翻译下 have one's head on the touch one’s head什么意思 It's hard for one to beat a computer.beat 这句话如何翻译? beat sb.out of one's boots 甚么意思 put back one’s head 第二次提问了.呜呜 have a been in one's head 翻译 急用!
