at all costs 不惜一切代价

at any rate 无论如何,至少
at best 充其量,至多
at first 最初,起先
at first sight 乍一看,初看起来
at hand 在手边,在附近
at heart 内心里,本质上
at home 在家,在国内
at intervals 不时,每隔...
at large 大多数,未被捕获的
at least 至少
at last 终于
at length 最终,终于
at most 至多,不超过
at no time 从不,决不
by accident 偶然
at one time 曾经,一度;同时
at present 目前,现在
at sb's disposal 任...处理
at the cost of 以...为代价
at the mercy of 任凭...摆布
at the moment 此刻,目前
at this rate 照此速度
