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。

探究五：动词的主动形式表示被动之意
1). 系动词无被动语态：以主动形式表示被动之意。常见的系动词有： be动词, look, seem, appear, feel, sound, smell, taste等 It smells terrible. 2).下列动词(词组)没有被动式： happen, take place, break out, belong to, cost, take An accident happened yesterday.

4). 在英语口语中，有时可用“get+过去分词”构成被动语态。如： I got dressed as quickly as l could. 我尽快穿上衣服。这样结构比较常见的搭配有：get arrested, get caught, get dressed, get drowned, get drunk, get lost, get married等。
