英文更多被动句

例如：Many people speak English. 谓语：speak的动作是由主语many people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：English is spoken by many people.主语English是动词speak的承受者. 所谓主动句就是由主动态动词(词组)作谓语动词的句子,而被动句则是由被动态动词(词组)作谓语动词的句子. 例如：He opened the door.他开了门.(主动句) The door was opened.门被开了.(被动句) 二、被动语态的构成 被动语态由“助动词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.现以teach为例说明被动语态在各种时态中的构成. 一般现在时：am／is／are＋taught 一般过去时：was／were＋taught 一般将来时：will／shall(be going to) be＋taught 现在进行时：am／is／are being＋taught 过去进行时：was/were being＋taught 现在完成时：have／has been＋taught 过去完成时：had been +taught 过去将来时：would(was/were going to) be+taught 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. 例如： Some more interesting novels were stolen last year. 一些新小说去年被写了.(没说小说是谁写的) This book was published in 1981.这本书出版于1981年. (2)强调动作的承受者,而不强调动作的执行者. 例如：the window was broken by Mike.窗户是迈克打破的. This book was written by him.这本书是他写的. Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保证. 四、主动语态变被动语态的方法 (1)把主动语态的宾语变为被动语态的主语. (2)把谓语变成被动结构(be＋过去分词) (根据被动语态句子里的主语的人称和数,以及原来主动语态句子中动词的时态来决定be的形式). (3)把主动语态中的主语放在介词by之后作宾语,将主格改为宾格.例如： All the people laughed at him. He was laughed at by all people. They make the bikes in the factory. The bikes are made?by them?in the factory. 五、含有情态动词的被动语态 含有情态动词的主动句变成被动句时,由“情态动词＋be＋过去分词”构成,原来带to的情态动词变成被动语态后“to”仍要保留. 例如： We can repair this watch in two days. This watch can be repaired in two days. You ought to take it away. It ought to be taken away. They should do it at once. It should be done at once.

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。

被动语态基本式：be+v-ed后者为及物动词过去分词，be动词在不同时态下有不同变化。由于动词过去分词确定，因此这个语态的变化就体现在be动词上。以下分别不同时态给出不同的be动词变化：1、一般现在时：am/is/are2、一般过去时：was/were3、现在进行时：am/is/arebeing4、过去进行时：was/werebeing5、一般将来时：willbe6、现在完成时：have/hasbeen7、过去完成时：hadbeen初中阶段应该主要就这几个，其中以前5个更为常见，当然还有情态动词的被动语态，如canbev-ed也常用的。希望对楼主有用。
