【be加done是什么时态】“be加done”是英语中一种常见的被动语态结构，常用于表达动作的承受者。在语法上，“be + 过去分词（done）”构成了被动语态的基本形式，它本身并不是一个独立的时态，而是不同动词时态下的被动形式。
一、总结
“be加done”是英语中被动语态的构成方式，表示“某人或某物被……”。它本身不是单独的时态，而是根据主语和动词的时态变化而变化。不同的时态下，“be”会变为相应的形式（如am/is/are/was/were/will be等），再加上“done”来构成完整的被动语态。

- 一般现在时：He is loved by everyone.（他被大家爱）
- 一般过去时：The book was read by me.（这本书被我读了）
- 一般将来时：The report will be written tomorrow.（报告将在明天被写）
