结论】从上面的例句我们可以看出，英语动词的语态有两种；主动语态和被动语态。被动语态中的动词必须是及物动词或相当于一个及物动词的短语动词。
1. 当主语是动作的发出者时，动词用主动语态/被动语态)，如例句1；当主语是动作的承受者时，动词用主动语态/被动语态)，如例句。
2. 被动语态的基本结构为：主语+be+过去分词+by+动作发出者，如例句。
3. 被动语态的时态是通过be动词/过去分词)体现。具体用法如下：
1）一般现在时的被动语态的结构为：主语+am/is/are+过去分词，如例句。
2）一般过去时的被动语态的结构为：主语+was/were+过去分词，如例句。
3）一般将来时的被动语态的结构为：主语+will be+过去分词，如例句6。
4）没有明确的动作发出者，“by+动词发出者”可以忽略。如例句。
注意：不及物动词、部分短语动词，如happen, take place, break out等没有被动语态。例如：
the accident took place last night.
这场车祸是昨晚发生的。
