介绍
一般现在时的被动语态用于描述动作的承受者,而不强调动作
的执行者。

在否定句中,我们使用助动词"be"的否定形式"am/are/is not"加上动词的过去分词形式来构成被动语态。

构成
否定句的一般现在时被动语态的构成形式如下:
主语 + 助动词 "am/are/is not" + 过去分词形式的动词
例子
以下是一些例子,展示了一般现在时被动语态在否定句中的使用:
1. The report is not written by me.(这份报告不是由我写的。


2. The cake is not made by her.(这个蛋糕不是她做的。


3. The document is not signed by the manager.(这份文件不是经
理签署的。


4. The problem is not solved by the team.(这个问题不是团队解决的。


注意事项
在一般现在时的被动语态中,动词的过去分词形式不随主语的单复数而变化。

助动词"be"的形式根据主语的单复数以及第三人称的情况而定。

总结
一般现在时的被动语态在否定句中的构成形式为主语 + 助动词"am/are/is not" + 过去分词形式的动词。

使用被动语态可以突出动作的承受者,而不是执行者。

在使用时要注意不同主语的单复数和第三人称的变化。

以上是对一般现在时的被动语态在否定句中的简要介绍。

一般现在时和一般将来时的被动语态结构

一般现在时和一般将来时的被动语态结构一、被动语态:含义:语态是动词的一种形式,用以说明主语与谓语动词之间的关系。

英语的语态共有两种:主动语态和被动语态。

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。

被动语态是动词的一种特殊形式,一般说来,只有需要动作对象的及物动词才有被动语态。

汉语往往用"被”、"受"、"给"等词来表示被动意义。

如: He openedthe door.他打开了这扇门。

(主动语态)The door was opened.这扇门被打开了。

(被动语态)Many people speak English.(主动语态,句子的主语many people是动作speak的执行者)English is spoken by many people.(被动语态,句子的主语English是动作speak的承受者)基本结构:主语+ be + done(及物动词的过去分词) +(by...).其中be 有时态、人称和数的变化,被动语态的时态是由be 的时态决定的,be 是什么时态,全句就是什么时态,be 动词后面的过去分过去分词部分不变。
