新概念英语第一册：被动语态2被动语态英语动词有主动语态和被动语态之分。
在主动句中，动词的主语是执行动作的人或物。
在被动句中，主语是动作的承受者。
在英语中被动词态用得很普遍，这样做能够避免用不明确的词作主语，或是将说话的重点放在事件而不是造成该事件的人或物上。
被动语态的构成： be +过去分词。
过去分词不一定指过去。
请看例句：(1)一般现在时形式： am/are/is +过去分词：The room is aired regularly.这个房间定期通风。
The knives are sharpened regularly.刀定期磨。
(2)一般过去时形式： was/were +过去分词：She was dressed in red.她身穿红色衣服。
The windows were opened this morning.窗户今早是开着的/被打开了。
(3)英语中表达感情的动词通常可用于被动式，这些动词如amuse, embarrass, worry, surprise, interest, upset等：She is embarrassed.她感到尴尬。
They were worried.他们感到担忧。

被动语态是英语中一种重要的语法现象，它表示动作的接受者。
在这一课中，我们将学习被动语态的构成、用法以及优势与局限性。
被动语态的构成主要包括两个部分：助动词（如 be, become, get 等）和过去分词。
在英语中，被动语态主要用于强调动作的接受者，而不是动作的执行者。
此外，被动语态还可以用于避免直接指责，使语气更加委婉。
被动语态的用法主要分为以下几种情况：1.当动作的接受者比动作的执行者更重要时，可以使用被动语态强调接受者。
例如：The cake was eaten by the dog.（蛋糕被狗吃了。
）2.当不知道动作的执行者是谁时，可以使用被动语态。
例如：The window was broken.（窗户被打破了。
）3.为了避免直接指责，可以使用被动语态。
例如：The mistake was made by him.（错误是他犯的。
）被动语态的优势在于可以强调动作的接受者，使句子更加客观、委婉。
然而，被动语态也有局限性，它不能表示所有的动作，例如一些不及物动词和动词短语不能用于被动语态。
在学习被动语态后，我们需要进行大量的练习和应用，以巩固所学知识。
可以通过阅读、写作和口语练习，不断提高自己的英语水平。
总之，新概念英语第一册第 49 课让我们了解了被动语态的构成、用法和优势与局限性。
新概念英语一总结练习七被动语态【复习】一、总述:英语动词有两种语态,即主动语态(The Active Voice)和被动语态(The Passive Voice).主动语态表示主语是动作的执行者。
被动语态表示主语是动作的承受者。
They will build a new bridge over the river. (主动)A new bridge will be built over the river. (被动)汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,而英语用:助动词be + 及物动词的过去分词构成。

以give 为例,列表如下:一般现在时:am / is / are + given一般过去时:was / were +given一般将来时:shall / will +be+ given过去进行时:was / were + being + given现在进行时:am / is / are + being + given过去完成时:had + been + given现在完成时:have / has + been + given将来完成时:shall / will + have been + given过去将来时:should / would +be+ given现在完成进行时:have/has been being done含情态动词的被动语态:情态动词+be done[注]被动语态没有将来进行时和过去将来进行时。
2)被动语态的否定式:在第一个助动词后加not构成。
