1：英语语态有主动语态和被动语态两种。主动是动作的执行者，叫做主动语态；主语是动作的承受者，叫做被动语态。
Many people use computers. 许多人使用电脑。
Computers are used by many people. 电脑被许多人使用。
2：被动语态的基本结构是“be+及物动词的过去分词”（be + done）。Be有人称，数和时态的变化。一般现在时的被动语态结构：主语+am/is/are+及物动词的过去分词。
3：一般现在时的被动语态的句式变化：
（1）肯定句：主语+am/is/are+及物动词的过去分词。
如：Cars are made by them. 汽车是由他们制造的。
（2）否定句：主语+am/is/are+not+及物动词的过去分词。
如：Cars are not made by them. 汽车不是由他们制造的。
（3）一般疑问句：Am/Is/Are+not+主语+及物动词的过去分词？
如：Are cars made by them? 汽车是由他们制造的吗？
4：主动语态变成被动语态的三步曲：
（1）将主动结构的宾语变成被动结构的主语（宾语若为人称代词，宾格变成主格）。
（2）将主动结构的谓语动词变成“be+及物动词的过去分词”形式（注意人称，时态和数的变化）。
（3）在动词的过去分词之后加介词by，再将主动结构中的主语放在by之后（若为人称代词，主格变成宾格）。
