(1)动词不规则变化是指动词的过去式和过去分词不按一定的规则变化。

1)现在式、过去式、过去分词同形。如

  被父母夸奖我感到很高兴。
3)现在式与过去分词同形。如
come→came→come,become→ became→become,run→ran→run.
例句:
  It was aware of having been found,then it ran away.
  它觉察到自己被发现了,于是逃跑了。
4)现在式、过去式、过去分词三种各不同形。如

  (3)另注:
  1)一些动词变化的英美不同。
  <1>burn,dream,learn,spell,smell,lean,spill,spoil在美语中为规则动词;在英语中可为规则动词,不过用作不规则动词较为普通。
  <2>在美语中wake的过去分词也可用waked.
  <3> fit,quit和wet在英语中是规则动词;但在美语中是不规则动词,三种形式相同。
  <4>dive在英语中是规则动词;在美语中则为不规则:dive→dove→dived.
  <5>get的过去分词在美语中也常是gotten.
  2)字典里有少数动词的过去分词有两个,其中的一个字尾为“en”,此类字尾为“en”的过去分词现在多用作形容词,而不用作时态之一部份(即不用作完成时态里的过去分词)。
    如:ill-gotten wealth不义之财。gotten是作形容词用的过去分词。
  He has got wealth by ill means.
  他以不正当的手段得到钱财。got是完成式里的过去分词。
  3)助动词只有现在式和过去式,没有过去分词。
  现在式 过去式 过去分词
  shall should 无
  can could 无
  will would 无
  may might 无
  must 无 无
ought 无 无
