语法一点通
现在完成时态
语法点拨:现在完成时态
基本用法
用法(一):谈论个人经历
  构成:have/has(助动词)+done(过去分词)
  例如:I have heard of the person. 我听说过这个人
  说明:常常与副词ever, never连用。 I have ever heard of the person.
  否定:主语 + have/has + not +
  疑问:Have/Has+主语+?
  注意:have/has been to 与have /has gone to
用法(二):表示“某动作从过去一直持续到现在”。
  (持续的时间用for 或since 短语表达)
  构成:have/has + done + for + 时间段; have/has + done + since + 时间点
  此时与现在完成进行时态的用法相同。
  如:He has watched TV for half an hour. = He has been watching TV for half an hour.
  说明:如果句中动词为非延续性动词,不能直接与for和since的短语连用。
  如:He has got to Chengdu for 2 days. (错)
  如果把句中got to 变为可持续性动词(be), 就可以与for和since的短语连用。
  He has been in Chengdu for 2 days. (对)他到达成都已经2天了。
用法(三):表示“过去发生的动作对现在造成的影响”。
  构成:与用法(一)相同。 常常与just, already, yet等副词连用。
  例子:I have already eaten supper. 我已经吃了晚餐了。(含义:我现在不吃了)
     Have you eaten supper yet? 你已经吃过晚餐了吗?(含义:你现在想吃晚餐吗?)
  说明:副词already常用于肯定句。而yet 则用于否定和疑问句。在否定句中常常翻译为“还”。
  I haven’t eaten supper yet. 我还没吃晚餐。(含义:我现在想吃晚餐)
动词过去分词变化规则与不规则变化
(一)变化规则:与过去式规则相同。
  1. 一般直接在词尾加上ed。look---looked----looked
  2. 以e结尾的动词,直接加d。move---moved----moved
  3. 以y结尾,y前面是辅音字母的动词,变y 为i,再加ed。carry---carried-----carried
  4. 部分动词需双写尾字母,加ed。stop----stopped----stopped
(二)不规则变化:
  不规则动词的变化因词而异。但如对不规则动词的过去式和过去分词做一分析,就可发现其中的“规则”。为方便同学们记忆,现将部分不规则动词的原形、过去式和过去分词列出并规为五种类型。以便准确记忆。

  【拓展】
  一、延续性动词和终止性动词的概念
  英语中,动词按其动作发生的方式、动作发生过程的长短,可分为延续性动词和终止性动词。
  延续性动词表示能够延续的动作,这种动作可以延续下去或产生持久影响。如:learn, work, stand, lie, know, walk, keep, have, wait, watch, sing, read, sleep, live, stay等。
  终止性动词也称非延续性动词、瞬间动词或短暂性动词,表示不能延续的动作,这种动作发生后立即结束。如open, close, finish, begin, come, go, arrive, reach, get to, leave, move, borrow, buy等。
  二、延续性动词的用法特征
  1. 延续性动词可以用于现在完成时,其完成时态可与表示“段时间”的状语连用。表示“段时间”的短语有:for two years, during the past three years, since last year, how long等。
  如:I have learned English since I came here.
    自从我来到这儿就学英语了。
  2. 延续性动词不能与表示短暂时间的"点时间"状语连用。
  如:It rained at eight yesterday morning. (误)
  rain为延续性动词,而at eight表示“点时间”,前后显然矛盾。如果用延续性动词表示一瞬间的动作,可以借助come, begin, get等终止性动词来表示。上句可改为:It began to rain at eight yesterday morning. (正)
  又如:---When did you get to know Jack?
     ---Two years ago.
     ---Then you've known each other for more than two years.
     ---That's right.
  三、终止性动词的用法特征
  1. 终止性动词可用来表示某一动作完成,因此可用于现在完成时。如:
    The train has arrived. 火车到了。
    Have you joined the computer group? 你加入电脑小组了吗?
  2. 终止性动词表示的动作极其短暂,不能持续。因此,不可与表示一段时间的状语连用(只限肯定式).
    如:(1) 他死了三年了。
        误:He has died for three years.
        正:He has been dead for three years.
