●重点语法：被动语态
一．基本结构：be + 动词过去分词
肯定句：主语＋be + 过去分词＋（by ~） 否定句：主语＋be not ＋过去分词
一般疑问句：Be ＋主语＋过去分词＋（by ~）? 特殊疑问句：疑问词＋be＋主语＋过去分词＋（by ~）?
dbms
需注意：
进行否定句或疑问句句型转换时，如有助动词（have/has/had/will/would+been/be+过分），则在助动词上变；其余情况都直接在am/is/are/was/were上变化。
二．具体时态如下：
et是什么意思
一般现在时的被动语态：主＋am / is / are （not）＋过去分词
一般过去时的被动语态：主＋was / were ＋过去分词
现在进行时被动语态： 主语＋is / am / are + being ＋过去分词
现在完成时被动语态： 主语＋have / has ＋been ＋过去分词
一般将来时： 主语＋will ＋be ＋过去分词
过去将来时： 主语＋would + be ＋过去分词
过去进行时： 主语＋was / were + being ＋过去分词
过去完成时： 主语＋had + been +过去分词
现在完成进行时态： 主语+have/has +been+being+过去分词
含有情态动词的被动语态： 情态动词＋be＋过去分词
三．什么时候不用被动语态？
（1）look,sound,smell,taste等系动词，用主动形式表示被动含义。
The orange juice tastes nice. 橙汁尝起来很不错
（2）动词need,want,以及短语be worth后接动名词(doing)。 用主动形式表示被动含义hydrafresh
My flowers need watering. 我的花需要浇水
（3）某些表示主语内在“品质”或“性能”的不及物动词，如：write,wash,ll,read,clean,drive等。他们的主语为物时，用主语表示被动。cunnilingus
This kind of shirts lls well here 这种裙子在这里卖得很好。
（4）不及物动词或词组没有被动结构，如： take place(发生） happen （发生）appear（出现）disappear (消失）last(持续）
四. 主动语态变为被动语态. 方法是：
宾变主，主变宾，谓变be done ,时态不变，数格必须随主语变化
原来的主语，如果需要的话，放在by后面，如果没必要，可省略。
