九年级英语第三单元被动语态中的“省、补、变、加、留”

  被动语态中的“省、补、变、加、留”指学习被动语态时应注意的“省主语、补主语、变代词、加上to、保留by”这些关键内容。

  省主语,指主动语态变被动语态时,如果主动句中的主语为泛指情况的we, they, people时,被动句中将by短语省略。如:

  We speak English. →English is spoken.

  补主语,指将字面未出现行为者的被动句改为主动句时,应适当地补上主语,如we, they, people, someone等。如:

  A car is stolen. →Someone steals a car.

  变代词,指主动句中的宾语是宾格人称代词时,改为被动句要将其变为主格人称代词。如:

  We must send her to the hospital at once. →She must be sent to the hospital at once.

  加上to,如果主动句中含不带to的不定式(作宾语的补足语),变该句为被动句时,不定式前的to应恢复使用。如:

  We saw him leave the classroom. →He was seen to leave the classroom.

  保留by,指下列被动句中by短语不省略的情况:

  a. 当by短语不表示行为者,而表示使用的手段和方法时。如:

  Most of the work will be done by the computers.

  b. 强调by短语中的动作行为者时。如:

  Macao was forced by Portuguese more than four hundred years ago.

  特别提示:一般将来时的被动语态:shall / will be +p. p.

  现在完成时的被动语态:have / has been + p. p.

  现在进行时的被动语态:am / is / are + being + p. p.

  过去将来时的被动语态:should / would be + p. p.

  另外需特别注意的是英语中look, smell, feel, taste, sound等系动词和表示起止意义的动词begin, start, finish, stop等,主动形式可表被动意义。
