一般现在时的被动语态被动语态是英语中的一个重要语法结构,用来描述动作的承受者或受事者。
在一般现在时中,被动语态的构造是由“be”动词(am/is/are)和动词的过去分词组成。
一般现在时的被动语态用来表达一种普遍性的动作,即在现在时发生的动作。
在一般现在时的被动语态中,动作的执行者通常是不明确的或不重要的。
一般现在时的被动语态由以下结构构成:主语 + am/is/are + 过去分词 + 其他成分例如:The book is read by me.(这本书被我读了。
)The car is washed by him.(这辆车被他洗了。
)在一般现在时的被动语态中,变化的部分是“am/is/are”,其实际形式取决于主语的人称和数。
过去分词保持不变。
例如:I am invited to the party.(我被邀请参加派对。
)You are chosen as the winner.(你被选为获胜者。
)He is praised for his achievements.(他因其成就而受到赞扬。
)We are called by our parents.(我们被父母叫了。

例如:English is spoken all over the world.(英语在全球范围内被使用。
)Water is composed of hydrogen and oxygen.(水由氢和氧组成。
