【探究】
语态是动词的一种形式，表示主语（动作的发出者或动作的承受者）和谓语之间的关系。
语态分两种形式：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，即行为动作的对象。
注意：不及物动词是没有被动语态的。
被动语态的构成
be动词+及物动词的过去分词
情态动词+be动词+及物动词的过去分词
be动词随着主语的人称、数、时态的变化而变化。
A baby’s first month birthday is a special event in China and ____ with a special party.( )
A. celebrates B. is celebrated
C. was celebrated D. will celebrate
B
被动语态的用法
1. 在没有必要指出动作的执行者时，“by+动作的执行者”可以省略。
eg: I won’t leave my office until my work is finished.
2. 不知道动作的执行者是谁时，使用被动语态比较合适。
eg: Some new computers were stolen last night.
The Hong Kong-Zhuhai-Macao Bridge _____ in 2018. We are proud of it.( )
A. is completed B. is completing
C. was completed D. completes
C
被动语态的用法
3. 动词短语是不可分割的整体，改为被动语态时要保持其完整性，介词或副词不可以遗漏。
eg: The young trees must be taken good care of.
2. 带双宾语的动词变为被动语态时，常有两种方法：把主动语态的直接宾语变为被动语态的主语，间接宾语前通常加介词to或for；或把主动语态的间接宾语变为被动语态的主语，直接宾语不变。
eg: A Christmas present was sent to me by my uncle last year.
I was sent a Christmas present by my uncle last year.
