来源:Hellokid在线英语2020-05-11 19:44:34

   英语是一名语言学科,它的学习在于平时的积累,如何能学好英语,提高我们的英语口语以及英语写作能力,小编为大家总结了一些高频的英语句型,赶紧记起来吧。1.何时运用被动语态:

  (1)强调动作的接受者:America was discovered by Columbus.

  (2)不知谁是动作的执行者:You are wanted on the phone.

  (3)作客观说明:It is said that the meeting has been put off.(经典句型)

  2.主动变被动的基本方法:(说起来容易,掌握起来需要用心!)

  (1)主动语态中的宾语变为被动语态的主语。

  (2)谓语动词变为由“be + 过去分词”的形式,配合时态作相应变化。

  (3)主动语态主语置于介词 by之后,如无必需,则省略。

  (4)不及物动词没有被动语态。
