英语被动语态形式

这里提到的种类应该指的是时态。主动语态一共有16种时态。所以严格的说，也应该有16种被动语态。但是常见的也只有十来种。一般过去，一般现在，一般将来时的被动态。过去进行，现在进行，将来进行时态的被动语态。过去完成，现在完成，将来完成时态的被动语态。还有一般过去将来时的被动语态。

bdddc都需要用到被动语态，每一句的主语都是“被xxx”，所以要用be+过去分词，表被动

基本被动语态的格式是：be动词+及物动词的过去分词，但是“be＋及物动词的过去分词”结构不一定都是被动语态，有些动词（如be，feel，look，seem等）后面的过去分词已转化为形容词，用作表语表示状态。MyfathergavemeanMP4asapresent。被动语态：AnMP4wasgiventome（bymyfather）asapresent.IwasgivenanMP4asapresentbymyfather.AnMP4是主动语态的宾语，改被动语态要变成主语；介词要用by。

第一句dressed你肯定是把它当做东西了 所以是be+done其实这里的dressed是形容词性be dressed in是固定词组 穿着的意思她穿一身红第二句amused同理 都是形容词性不要把它当做动词来对待了

1.当句子的主语是动作的执行者时，谓语的形式是主动语态。当句子的主语是动作的承受者时，谓语要用被动语态。被动语态由助动词be+过去分词构成，时态通过be表现出来。例如：1）一般现在时：Youarerequiredtodothis.2）一般过去时：Thestorywastoldbyher.3）一般将来时：Theproblemwillbediscussedtomorrow.4）现在进行时：Thequestionisbeingdiscussedinthemeetingroom.5）过去进行时：Thenewroadwasbeingmade.6）现在完成时：Thenovelhasbeenread.7）过去完成时：Hesaidthattheworkhadbeenfinished.8)过去将来时：Hesaidthatthetreeswouldbeplantedsoon.2.一些特殊的被动结构1）带情态动词的被动结构：Theproblemmustbesolvedsoon.2）带不定式的被动结构：Thehomeworkneedstobedonewithcare.3）短语动词的被动结构：例1）Thebabyislookedaftercarefully.用于这类被动结构的短语动词要把它们作为整体看待。这类结构有以下几种：①（不及物）动词+介词：agreeto,askfor,callfor,laughat,listento,lookafter,operateon,sendfor,talkabout,thinkof等。②（及物）动词+副词：bringabout,carryout,findout,giveup,handin,makeout,passon,pointout,putaway,putoff,takeup,thinkover,turndown,turnout,wipeout,workout等。③动词+副词+介词：doawaywith,faceupto,giveinto,lookdownupon,makeupfor,putupwith等。例2)Attentionmustbepaidtoyourpronunciation.用于这类被动结构的短语动词最多见的是“动词+名词+介词”这一结构。如：catchsightof,keepaneyeon,makeuseof,makeafoolof,payattentionto,putanendto,setfire/lightto,takecareof,takeholdof,takenoticeof等。例2与例1的不同点在于，它们用于被动时态能有两种形式。第一种形式是把“动词+名词+介词”作为整体看待。第二种形式是把其中的“动词+名词”作为“动词+宾语”的结构处理。4）带复合宾语的动词在改为被动语态时，一般把主动结构中的宾语改成主语，宾语补足语保留在谓语后面。例如：Wealwayskeeptheclassroomclean.(比较：Theclassroomisalwayskeptclean.)
