1、被动语态语态：表示主语和谓语动词之间的关系。英语有两种语态，即主动语态和被动语态。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。如：ManystudentsstudyEnglish.(主动语态)Englishisstudiedbymanystudents.(被动语态)语态什么时候可以使用被动语态呢？一、行为主体不明确，不必说出或者无法说出动作的执行者时。例如：Suchbooksarewrittenforchildren.这些书是为儿童写的。Footballisplayedallovertheworld．二、不易找到或根本就不可能

2、找到动作的执行者时。例如：Mybikewasstolen．我的自行车被盗了。三、汉语中含有“据说”、“据悉”、“有人说”、“大家说”等时。例如：Itissaidthatonedayheclimbedtothetopofahouseand……ItwasreportedthathermotherdiedofSARS.众所周知……Itiswellknownthat…据推测说……Itissupposedthat…四、汉语中含有“被”、“由”等词时。例如：TinaisaskedtocomebyPaul．Tina是被Paul叫来的。五、某些句子习惯上用被动语态。
