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。

将下列句子变为被动语态
语态是动词的一种形式,表示句子中主语和谓语动词的关系,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。
只有及物动词才能用于被动语态。
一．被动语态的时态：1.一般现在时的被动语态：am /is/ are +动词的过去分词2.一般过去时的被动语态：was /were +动词的过去分词3.一般将来时的被动语态：will be +动词的过去分词4.现在进行时的被动语态：am /is /are +being +动词的过去分词5.现在完成时的被动语态：have /has +been +动词的过去分词6.情态动词的被动语态：情态动词+ be +动词的过去分词二．被动语态的基本用法:(1) 需要强调动作的承受者时The Great Wall is enjoyed by millions of people all over the worldEnglish is widely spoken in the world now.(2) 不知道或没必要指出动作的执行者时Mr. Wang is invited to the meeting today .The problem is dealt with now .(3) 当说话人需要强调客观时It is said that she was a beauty when she was young .三．主动主动语态变被动语态的变法：口诀：宾变主，主变宾，谓变be done ,时不变，数格必须随被变。
注：1.主动、被动的时态要一致。
2.主动、被动的句式要一致。
3.变成的被动语态的主语与谓语在单复数上保持一致。
语态转换不被动语态的步骤1, 把原主动句中的宾语转换为被动语态的主语2, 把动词改为被动语态形式即"be+过去分词"。
3, 原来主动语态句子中的主语,如果需要就放在by的后面以它的宾格形式出现(因为by是介词,后面需跟宾格作介词的宾语。
