一般过去时和一般将来时的被动语态分别用 was/were + done 和 will be + done 表示。
要点讲解
- 一般过去时被动：was/were + 过去分词：The bridge was built in 1990. 这座桥建于1990年。
- 一般将来时被动：will be + 过去分词：The meeting will be held next week. 会议下周举行。
- 含情态动词的被动：情态动词 + be + 过去分词：The work must be finished today. 这项工作今天必须完成。
- be going to 的被动：be going to be + 过去分词：The plan is going to be changed. 这个计划将要改变。
- 被动语态疑问句：Was the window broken? / Will the work be done tomorrow?
- 含双宾语的句子变被动有两种：give sb. sth. → sb. be given sth. / sth. be given to sb.：I was given a book. = A book was given to me.
- 含复合宾语（宾语+宾补）的被动：宾语变主语，宾补保留：They call him Tom. → He is called Tom.
经典例句
- The 2026 World Cup was held in North America.
2026年世界杯在北美举行。 - The trees will be planted next spring.
这些树明年春天将种植。 - The letter was written by my mother.
这封信是我妈妈写的。
易错提醒
- 被动语态选择题先看主语与动词的关系（主动/被动），再确定时态，最后选 be 的形式。
