被动语态1.Kellycleansthehouseeveryday.(该句为主动语态，主语Kelly是动作clean的执行者，宾语thehouse是动作clean的承受者。)2.ThehouseiscleanedbyKellyeveryday.(该句为被动语态，主语thehouse是动作clean的承受者，动作的执行者Kelly由介词by引出。)

被动语态通常由“助动词be+及物动词的过去分词”构成。当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者，或者只需强调动作的承受者时，要用被动语态。如：Englishisspokeninmanycountries.Suchbookswerewrittenformiddleschoolstudents.Thecomputershouldbeturnedoffatonce.一般现在时被动语态的各种句式结构AstoryistoldbytheoldmanonTVonSunday.主语谓语宾语状语肯定式主语+am/is/are+过去分词（+by…)AstoryisnottoldbytheoldmanonTVonSunday.否定式主语+am/is/are+not+过去分词

Itsmellsterrible.2).下列动词(词组)没有被动式：happen,takeplace,breakout,belongto,cost,take

Anaccidenthappenedyesterday.注意3).不及物动词sell,wash,read,write,open,close,shut,lock,wear等，常用主动形式表示被动意义。
