主动句变为被动句所遵循的4个步骤：
1. 把原主动句中的宾语变为被
动句的主语。
2. 把动词变为被动形式，即be+
过去分词，并注意其人称和
数随主语的变化，而动词的
时态则保持不变。
3. 原主动句的主语如需要则放
在by后面以它的宾格形式出
现（注意代词的宾格），如
不需要则可省略。
4. 其它的成分（定语、状语）
不变。
口诀：
主宾互换格要变
谓语变化时态定
by加被动宾语前
其他一律都不变
Grammar
①含有双宾语的主动句变为被动语态时，通常把
指 “人”的间接宾语变为主语，而指“物”
的直接宾语则不变。
He gave me a book yesterday.
→I was given a book (by him) yesterday.
②如果要把指“物”的直接宾语变为主语，则在
间接宾语前加to或for。
I brought him some food.
→Some food was brought to him (by me).
Grammar
③含有复合宾语的主动句变为被动语态时，要将
其中的宾语变成主语，宾语补足语不变。
