isdividedintopieces

byher.1.将主动语态的宾语变为被动语态的主语；2.将主动语态的谓语动词变为“be＋过去分词”结构(be有人称、时态和数的变化)

；3.将主动语态的主语变为介词by后的宾语，放在谓语动词后面（此介词短语常可省略)；4.主动语态句子的时态、时间状语等变为被动语态时不需要变化。主动语态变为被动语态的方法：被动语态的基本结构：be+done（动词的过去分词）

一般现在时态的被动结构：am/is/are+done

一般过去时态的被动结构：was/were+done

一般将来时态的别动结构：willbe+done

情态动词的被动结构：情态动词+be+done

小贴士：

主动语态中的谓语动词是及物动词时才可变为被动语态。5.Heoftenswimsintheriver.
