Unit6SectionA1a-2c被动语态（ThePassiveVoice).主动语态与被动语态：英语动词有两种语态,即主动语态(TheActiveVoice)与被动语态（ThePassiveVoice)。主动语态表示主语是动作的执行者;被动语态表示主语是动作的承受者。

e.g.1.TheymaketrainsinZhuzhou.TrainsaremadeinZhuzhou.

2.Thefarmersgrowcottoneveryyear.Cottonisgrownbythefarmerseveryyear.

主动语态被动语态主动语态被动语态

主动语态变被动语态的步骤：1、主动语态的宾语变为被动语态的主语；2、主动句的谓语动词变为被动结构；3、主动句的主语变为被动句的宾语，由by引出，当不强调动作的执行者时，常省略。4.其它成分不变。主动语态变被动语态规则宾语提前变主语，原主变宾by后见，记住时态不要变，还有人称be关键。TheyplayfootballonSunday.Lucydoesthehomeworkintheevening.WemakethesemachinesinBeijing.FootballisplayedbythemonSunday.ThehomeworkisdonebyLucyintheevening.ThesemachinesaremadeinBeijing.Learningaims:2).Thekeysentences:
