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。

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。
如：- 主动语态：I cooked dinner.（我做了晚饭。
）- 被动语态：Dinner was cooked by me.（晚饭是我做的。
）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。

语法专练---被动语态一、语态概述我吃了一个苹果，那现在苹果怎样了？苹果被我吃了。
正如汉语中的被字句，英语中的“被字句”我们称之为被动语态。
英语中有两种语态：主动语态和被动语态。
英语的语态是通过动词形式的变化表现出来的。
主动语态表示主语是动作的执行者。
巧记为：主动、主动、主去动。
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。
巧记为：被动、被动、主被动。
例如：English is spokenby many people.主语English是动词speak的承受者。
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“be＋及物动词的过去分词”构成。
不及物动词本身没有被动语态。
及物动词---本身意义不完整，后必须带宾语，有些还可以带双宾。
不及物动词---本身意义完整，不需要带宾语，如带宾语必须通过介词。
人称、数和时态的变化是通过be的变化表现出来的。

一般现在时：am／is／are＋eaten一般过去时：was／were＋eaten一般将来时：will/shall/be going to be＋eaten过去将来时：would/should/be going to be＋eaten现在进行时：am／is／are being＋eaten过去进行时：was／were being＋eaten现在完成时：have／has been＋eaten过去完成时：had been＋eaten歌诀是：被动语态be字变，过去分词跟后面。

规则:被动语态由“助动词be+及物动词的过去分词”构成。
第一，助动词be 要随着人称和数的变化而变化，第二，助动词be要随着时态的变化而变化。

2. 被动语态的特殊结构形式1)带情态动词的被动结构其形式为情态动词＋be＋过去分词。
例The baby should be taken good care of by the baby-sitter. 婴儿应该受到保姆良好的照顾。
2) 有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一宾语仍然保留在谓语后面。
通常变为主语的是间接宾语。
His mother gave him a present for his birthday.→ He was given a present by his mother for his birthday.3) 当“动词+宾语+宾语补足语”结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。
例Someone caught the boy smoking a cigarette. →The boy was caught smoking a cigarette.4）在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为被动结构时，要加to。
例Someone saw a stranger walk into the building.→A stranger was seen to walk into the building.5) 有些相当于及物动词的动词词组，如“动词＋介词”，“动词＋副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。
其中的介词或副词也不能省略。
例The meeting is to be put off till Friday. 会议将推迟到星期五。
3. 非谓语动词的被动语态v.+ ing形式及不定式 to do 也有被动语态(一般时态和完成时态) 。
例I don't like being laughed at in the public.二、如何使用被动语态学习被动语态时，不仅要知道被动语态的各种语法结构，还要知道在哪些情况中使用被动语态。
1. 讲话者不知道动作的执行者或不必说出动作的执行者 (这时可省 by 短语)。
例 My bike was stolen last night.2. 借助被动的动作突出动作的执行者。
例 I was given ten minutes to decide whether I should accept the offer.3. 为了更好地安排句子。
例The well-known person got on the bus and was immediately recognized by people. （一个主语就够了）三、 It is said that+从句及其他类似句型一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“It＋be＋过去分词＋that从句”或“主语＋be＋过去分词＋to do sth.”。
有：It is said that…据说,It is reported that…据报道，It is believed that…大家相信，It is hoped that…大家希望，It is well known that…众所周知，It is thought that…大家认为，It is suggested that…据建议。
例It is said that the boy has passed the national exam（＝The boy is said to have passed the national exam. ）四、谓语动词的主动形式表示被动意义1.英语中有很多动词如 break，catch，clean，drive，lock，open，sell，read，write，wash等，当它们被用作不及物动词来描述主语特征时，常用其主动形式表达被动意义,主语通常是物。
