初中中的被动语态用法详解
初中中的被动语态用法详解被动语态是英语中一个常用的语法结构,包含了及物动词的被动形式。
初中阶段,学生们需要逐渐掌握被动语态的用法。
本文将详细介绍初中中的被动语态用法。
一、被动语态的基本构成被动语态的基本构成由be动词的适当形式+过去分词构成。
be动词的形式根据句子的时态和主语的人称而定。
过去分词则根据动词的一般过去时的变化规则。
例如:- The car is repaired.(句子时态:一般现在时)- The car was repaired.(句子时态:一般过去时)- The car will be repaired.(句子时态:一般将来时)二、被动语态的用法1. 没有明确的执行者在被动语态中,我们强调动作的接受者而非执行者。
有时,在句子中并没有明确指出执行动作的人或事物。
例如:- The window was broken.(窗户被打破了。
)- The book will be published next month.(这本书将在下个月出版。
)2. 隐藏执行者在某些情况下,句子中刻意隐藏了动作的执行者。
例如:- The cake was eaten.(蛋糕被吃了。
)3. 顺序执行之动作被动语态常用于描述一系列按照一定顺序执行的动作。
例如:- The eggs are washed, peeled, and then boiled.(鸡蛋洗净、剥皮,然后煮熟。
)4. 惯用表达被动语态在某些固定的表达方式中也得到了广泛使用。
例如:- The decision was made.(决定已经做出。
)- The question was answered.(问题已经回答。
)三、主动语态与被动语态的转换在主动语态与被动语态之间进行转换时,需注意以下几点:1. 意义的改变:动作的焦点转移到了接受者身上,原主语成为了新的宾语;2. 动词形式的变化:be动词的形式和动词的过去分词形式相关;3. 语态的时态保持一致:主动语态的时态与被动语态的时态保持一致。

初中英语语法——被动语态用法总结归纳被动语态是英语语法中的重要部分,学好被动语态的用法可以帮助学生更准确地理解和使用英语。
下面是被动语态用法的详细总结归纳。
1.被动语态的构成:被动语态由“助动词be+过去分词”构成,根据时态的不同,助动词be的形式也会发生变化。
如:- 一般现在时:am/is/are + 过去分词- 一般过去时:was/were + 过去分词- 一般将来时:will be + 过去分词- 现在进行时:am/is/are being + 过去分词- 过去进行时:was/were being + 过去分词- 现在完成时:have/has been + 过去分词- 过去完成时:had been + 过去分词2.被动语态的用法:被动语态用来强调动作的承受者(主语)而不是执行者,并且常用于以下情景:2.1当我们不知道或不关心动作的执行者时。
例如:The cake was eaten.(蛋糕被吃了。
)2.2当动作的执行者已知,但我们要强调动作的承受者时。
例如:The house was built by my grandfather.(这座房子是我爷爷建的。
)2.3当我们要避免使用第一人称或第二人称时。
例如:Mistakes were made.(犯了错误。
)3.被动语态的注意事项:在使用被动语态时,需要注意以下几点:3.1表示动作的动词要用过去分词形式。
过去分词的形式有规律变化和不规律变化两种。
如:- 规律变化:原形 + ed,例如:played, watched, called- 不规律变化:需要记忆,例如:born, written, eaten3.2被动句的主语是动作的承受者,通常出现在句子的前面。

)3.3 不及物动词不能构成被动语态。
不及物动词没有宾语,因此不能强调动作的承受者。

本文将详细介绍初中英语中被动语态的用法。
一、被动语态的基本构成被动语态的构成由“be”动词的不同形式加上动词的过去分词组成。
其中,“be”动词的形式根据主语的不同而变化,包括is、am、are(现在时态)以及was、were(过去时态);过去分词则是动词的过去式形式。
例如:1. 现在时态的被动语态:The book is written by Peter.(这本书是彼得写的。
)2. 过去时态的被动语态:The house was built last year.(这所房子是去年建的。
)二、被动语态的用法被动语态在英语中广泛应用于多种语境,下面将介绍几种常见的用法。
1. 表示动作的承受者或受事者被动语态常用于强调动作的承受者或受事者,而不强调动作的执行者。
例如:The cake was made by my mom.(这个蛋糕是我妈妈制作的。
)The car was repaired by a mechanic.(这辆车是由一个机修工修理的。
)2. 不知道或没有必要提及动作的执行者有时候,我们并不知道或者没有必要提及动作的执行者,这时被动语态可以很好地解决这个问题。
例如:The window was broken.(窗户被打破了。
)The letter has been sent.(信已经寄出了。
)3. 形容词的被动用法有些形容词可以用于被动语态,表示事物属性或状态的变化。
例如:He is interested in science.(他对科学感兴趣。
)I am impressed by his performance.(他的表演给我留下了深刻印象。
)4. 与情态动词连用被动语态可以与情态动词连用,表示对某种可能性或许诺的推测。
