有one year ago这样的说法吗?

有one year ago这样的说法吗? One Year Ago 歌词 one year ago 和a year ago 没有任何区别吗?可否说明一下：one 和a 在任何情况下都可以互换的吗? a half of year有这样的说法吗?a half of year 是半年还是一年半? 歌曲one year ago 的歌词中文意思 one year ago和one year earlier区别?写文章的时候用哪个呢? one year ago和one year earlier区别?写文章的时候用那个好呢? 为什么是one year ago而不是ago one year?one year ago的话词性上来讲说不通啊 last year=one year ago 去年.一年前? he has kept a car since one year ago（对since one year ago 提问） 一句话,我钻牛角尖了,朋友们指点一下一年之前,一年之后a year ago,a year later,还是 one year ago, one year later若是都可以的话,在语法上,或者习惯上有什么不同呢谢谢哈~~~ 请问英文的Happy New Year.可以说成Happy a New year.有这种说法吗? 英语翻译琳恩-玛莲的one year ago 我要翻译成中文的 They _____ speak to each other one year ago.用could,can的相应形式填空 one year ago 是具体时间吗可以用 have been 吗 since one year ago 可与延续性动词连用吗应该是现在完成式 one year have four seasons的语法问题?one year have four seasons和 there are four seasons in a year.的意思有区别吗?
