Read the sentences frm the reading passage and summarise the grammar rules.
be + 动词过去分词
语态： 表示主语和谓语动词之间的关系。主动语态： 主语是动作的执行者。I clean the blackbard.我擦黑板。被动语态： 主语是动作的承受者。。）The blackbard is cleaned by me.黑板被我擦了。
1、不知道或没有必要指出谁是动作的执行者时。The bridge was built last year.这座桥是去年建造的。He was elected chairman.他被选为主席。2、 当更加强调动作的承受者时。此时动作的执行者由by引导置于谓语动词之后，不需要时可以省略。The rm hasn't been cleaned yet.房间还没有打扫。The tiger was killed by him.老虎被他杀死了。
3、当动作的执行者不是人时，多用被动语态。The windw was blwn by wind.窗户被风吹开了。The whle village has been washed away by the fld.整个村庄都被洪水冲走了。4、表示客观的说明常用"It is + 过去分词."句型。It is reprted that…据报道It is said that…据说It is believed that…大家相信It is suggested that…有人建议
(1)将主动句的宾语变为主语：注意：如果主动句的宾语是代词，需将其由宾格变为主格。Tm killed him. → He was killed by Tm.(2)将动词改为"be+过去分词"。They held a meeting yesterday. → A meeting was held by them yesterday.(3)将主动语态的主语改为be…放在谓语动词后。注意：如果原主语是代词，则应由主格变为宾格。He sang a sng. → A sng was sung by him.
(1)主动句中的主语如果是peple, we, yu, they, smebdy等含糊地表示"人们"、"大家"的单词，变为主动句时，通常删去"by…"，但原主语被强调者除外。如：They set up this hspital in 1975. → This hspital was set up in 1975.Only he can finish the jb. → The jb can be finished nly by him.
主动语态变为被动语态的注意事项
(2)含有双宾语，即直接宾语和间接宾语的句子，每个宾语都可变为被动语态的主语，即其被动语态有两种形式。但多以间接宾语作主语。Jack tld us the truth.杰克告诉了我们真相。We were tld the truth by Jack.The truth was tld (t) us by Jack.
肯定句： 主语 + am/is/are + 过去分词 + 其他。English is spken in many cuntries.否定句： 主语 + am/is/are + nt + 过去分词 + 其他。The rm is nt cleaned every day.一般疑问句： Am/Is/Are + 主语 + 过去分词 + 其他？Is this car made in China?
一般现在时的被动语态
肯定句： 主语 + will be + 过去分词 + 其他。A new schl will be built next year.否定句： 主语 + will nt (wn't) be + 过去分词 + 其他。The meeting wn't be held tmrrw.一般疑问句： Will + 主语 + be + 过去分词 + 其他？Will the wrk be finished tmrrw?
一般将来时的被动语态
‌一般情况：直接加 -edwrk → wrked play → played‌以不发音的 -e 结尾：加 -d‌live → lived hpe → hped‌以“辅音字母 + y”结尾：变 y 为 i，再加 -edstudy → studied try → tried‌重读闭音节结尾（辅元辅结构）：双写末尾辅音字母，再加 -ed‌stp → stpped plan → planned
动词过去分词的变化规则
ABC型（原形、过去式、过去分词均不同）see → saw → seen eat → ate → eaten‌AAA型‌（三者相同）hit → hit → hit put → put → put‌ABA型‌（原形 = 过去分词）becme → became → becme cme → came → cme

少数动词有两种过去分词形式（用法不同）：learn → learned/learntdream → dreamed/dreamtburn → burned/burntsmell → smelled/smeltlie（躺）和 lay（放置）容易混淆：lie（躺）：lie → lay → lain（不及物，不能用于被动语态）lay（放置）：lay → laid → laid（及物，可用于被动语态）
