时态是英语中非常重要的语法知识,它涉及到动词的形式变化和语态的转换。在英语中,时态分为现在时、过去时和未来时。而主动和被动语态则是时态中的一个重要概念。
在英语中,主动语态通常用于表达主语主动执行动作,而被动语态则用于表达主语被动地接受动作。例如,主动语态的句子“Tom writes a letter”,意为汤姆写一封信,而被动语态的句子“the letter is written by Tom”,意为这封信是被汤姆写的。
时态的主动和被动语态在形式上有所不同。例如,在现在时,主动语态的动词形式为“do/does + 动词原形”,而被动语态的动词形式为“am/is/are + 过去分词”。在过去时,则主动语态的动词形式为“did + 动词原形”,被动语态的动词形式为“was/were + 过去分词”。
下面是几个时态的主动和被动语态的表格:
| 现在时 | 主动语态 | 被动语态 | | --- | --- | --- | | 第一人称 | I write | I am written | | 第二人称 | You write | You are written | | 第三人称单数 | He/She/It writes | He/She/It is written | | 第三人称复数 | They write | They are written |
