have has 主语 beendone 二 用法 1 表示一个被动的动作在说话之前已完成 强调过去的动作对现在造成的影响或结果 通常与already yet just never recently等副词连用 2 表示一个被动的动作或状态从过去开始一直持续到现在 常与for或since引导的时间状语连用 或用于howlong引出的句子中 3 用在时间或条件状语从句中 表示将来已完成的被动动作 即用现在完成时的被动语态代替将来完成时的被动语态 学法点拨常与现在完成时连用的时间状语 already已经yet已经recently lately最近sincethen从那时起eversince自那以来ever曾经sofar迄今为止foralongtime很长一段时间bynow到现在为止inrecentyears在最近几年里in during overthepast lastfewyears在过去的几年里 三 注意事项 1 与一般过去时的被动语态的区别 2 borrow begin start buy marry open join等非延续性动词的现在完成时的被动语态不能与表示一段时间的状语连用 若要表达相应的意思 需要改变动词或时态 这本书借了一周了 thebookhasbeenborrowedforaweek thebookhasbeenkeptforaweek 这个工程已经开始多久了 howlonghasthisprojectbeenstarted howlongagowasthisprojectstarted 学法点拨非延续性动词的否定式可表示动作的持续过程 具有持续性 因而可与since或for引出的时间状语连用 3 带有双宾语的动词 如give send bring take teach show tell make sing write sell buy lend offer hand pass get等 变为被动语态时 一般是把指人的间接宾语变为主语 如果将直接宾语变为被动句的主语 间接宾语前要加to或for 4 带有复合宾语 宾语 宾语补足语 的动词变为被动语态时 只能将宾语变为主语 原来的宾语补足语保持不动 主动语态中不带to的不定式作宾补 在被动语态中要加上to 5 短语动词变为被动语态时 要注意保持短语动词的完整性 不可漏掉动词后面原有的介词或副词 此类短语动词有 动词 介词referto lookafter callon relyon lookfor lookat listento dreamof meetwith laughat resultin waitfor dealwith operateon 动词 名词 介词payattentionto
