过去某一点时间正在进行的动作或某段时间内一直进行的动作 构成 was were doing 现在分词 过去进行时的标志词有 at8o clocklastnight thistimeyesterday等 1 现在分词的构成1 一般动词在词尾加 ing 读 i 如go going 2 以不发音字母e结尾的动词 先去掉e 再加 ing come comingmake makingwrite writing 3 以重读闭音节结尾的动词 如果末尾以一个辅音字母结尾 应先双写这个字母 再加ing x和w结尾的除外 如 get gettingswim swimmingbox boxing4 以字母y结尾的单词 直接加ing 如 carrying playing studying 5 以字母ie结尾的动词 变ie为y 再加ing die dyinglie lying6 以元音字母加e结尾 或以e结尾 且e发音的动词 直接加 ing see seeingbe being 2 使用进行时态的注意事项 1 一些动词 如see hear love like know remember understand have等表示感情 知觉和状态的词 一般不用于进行时态 2 在there和here引起的句子中 常用一般现在时代替现在进行时 eg herecomesthebus theregoesthebell 过去进行时 含义 表示过去某个时刻正在进行的动作 结构 was were doing例句 iwashavinganenglishclassatthistimeyesterday 现在进行时 含义 表示现在正在进行的动作 结构 is am are doing例句 iamhavinganenglishclass 3 过去进行时和现在进行时的区别 4 过去进行时和一般过去时的区别 1 过去进行时表示过去正在进行的动作 而一般过去时则表示一个完整的动作 如 theywerewritingletterstotheirfriendslastnight 昨晚他们在写信给他们的朋友 没有说明信是否写完 theywroteletterstotheirfriendslastnight 他们昨晚写了信给他们的朋友 表达了他们已写好的意思 整个写的过程已完成 讲解 2 当动作延续较长时间时或表示厌烦 赞美等感情色彩时 常用过去进行时表示 如 hewasthinkingmoreofothersthanofhimself 他考虑别人的比考虑自己的多 表示说话者赞扬的口气 theboywasalwaysmakingtroublethen 那时 他总是惹麻烦 表示说话者厌烦的口气 when while用法区别 1 when指atorduringthetimethat 它既指时间点 也可指一段时间 while是duringthetimethat只表示一段时间 所以when引导的时间状语从句中的动词可以是瞬间性动词 也可以是延续性动词 而while从句中的动词必须是延续性动词 itwassnowingwhenwearrivedatthestation whileshewastyping someoneknockedatthedoor 2 由when引导的时间状语从句常用一般过去时 而主句用过去进行时 但是在并不强调哪一个动作持续时间更长或者哪一个动作是打断性的 interruptive 行为的情况下 when引导的状语从句也可以使用过去进行时 如果强调从句和主句的动作同时发生 两句都用过去进行时 则多用while引导从句 hefinallyfellasleepwhen
