at (the) best充其量,至多
at all costs不惜任何代价
at the cost of… 以…为代价
at all events无论如何
at heart在内心,实质上
at intervals不时,时时
at length终于,最后,详细地
at a loss困惑,不知所措
at present目前,现在
at random随意地,任意地
at any rate无论如何,至少
at a loss 茫然,不知所措
at a time 一次,每次
at all costs 不惜一切代价
at all events 不管怎样,无论如何
at all times 随时,总是
at all 丝毫(不),一点也不
at any rate 无论如何,至少
at first sight 乍一看,初看起来
at first 最初,起先
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 last 终于
at least 至少
at length 最终,终于
at most 至多,不超过
at no time 从不,决不
at one time 曾经,一度;同时
at present 目前,现在
at someone's disposal 任……处理
at the mercy of 任凭……摆布
at the moment 此刻,目前
at this rate 照此速度
at times 有时,间或
at first sight乍一看,初看起来
at a loss 不知所措,困惑;亏本地
at all costs 不惜任何代价,无论如何
at all events 无论如何,不管怎样
at any rate 无论如何;至少
