被动语态：把重点换一换 · PET / B1
天天向上 · 原创语法学习讲义
把焦点放在接受动作的人或事物上：学习 B1 常用的一般现在、一般过去和情态动词被动句。
结构是 be + 过去分词
时态和单复数在 be 上变化，动作词使用过去分词。
The rooms are cleaned daily. The room was cleaned yesterday.
房间每天打扫。这个房间昨天打扫过。
不是 are clean 或 was cleaning；后者是进行时结构，意思不同。
从主动转换焦点
主动句的动作接受者可成为被动句主语，必要时用 by 引出动作执行者。
A local artist painted the mural. The mural was painted by a local artist.
一位本地艺术家画了壁画。壁画由一位本地艺术家绘制。
保留原句时间：painted 转成 was painted，不随意变成 is painted。
情态动词被动
can / must / should 等后使用 be + 过去分词，表达可能、规定和建议。
Old batteries should be taken to a collection point.
旧电池应送到回收点。
should be taken 不能写 should taken 或 should be took。
不是每个动词都能被动
需要有动作接受者。arrive、happen 等不及物动词通常不用被动。
The accident happened near the station.
事故发生在车站附近。
不写 was happened。by 表施事者；with 可表工具，如 cut with scissors。

答案与解释
1. A · are made
uniforms 是复数，通常生产用 are made。
2. A · was built
2018 年的建造，用 was + 过去分词 built。
3. A · be switched off
must 后用 be + 过去分词 switched。
4. A · The road was repaired last week.
原句一般过去时，被动保留为 was repaired。
5. B · by
动作执行者用 by 引出。
6. A · The accident happened yesterday.
happen 没有这里所需的宾语，不能机械变被动。
7. C · The window.
被动句主语 the window 是被打破的对象。
8. B · taken
take 的过去分词是 taken；should be taken。

参考表达
Used paper is collected in special boxes in every classroom. The boxes are emptied on Fridays, and the paper is taken to a recycling centre. Last year, new labels were added to help students sort their rubbish. Plastic wrappers must not be put in the paper boxes. Old batteries should be taken to the school office because they need special treatment. The system is checked by our environment club.
