6、态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。例如：ManypeoplespeakChinese.谓语：speak的动作是由主语manypeople来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chineseisspokenbymanypeople.主语English是动词speak的承受者。（二）被动语态的构成被动语态由“be＋及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。一般现在时：am／is／are＋动词的过去分词一般过去时：was／w

7、ere＋动词的过去分词一般将来时：will／shallbe＋动词的过去分词现在进行时:am/is/are+being+动词的过去分词含有情态动词的被动语态：情态动词+be+动词的过去分词(must/may/can/should)（三）被动语态的用法（1）不知道或没有必要说明动作的执行者是谁。Thisbridgewasfoundedin1981.这座桥竣工于1981年。（2）强调动作的承受者，而不强调动作的执行者。例如：TheglasswasbrokenbyMike.玻璃杯是迈克打破的。Thisbookwaswrittenbyhim.这本书是他写的
