Unit 8：The phone was kept in a drawer.（过去时被动）；Digital skills should be taught at school.（情态被动）。
为什么科技话题必考描述产品（手机哪造的、消息几秒发出、技能该被教），被动最客观。
情态被动 = modal + be + p.p.It can be done in five minutes.（不是 can done）。
从 KET 到 PET 的进阶提醒KET（A2）要求"能认出、能填对"；PET（B1）要求"会用、会说、会写"。同一个知识点，A2 只考单选，B1 还要你在 email 和口语里主动输出。所以这一课别停留在"看懂"，一定要把第 ⑧ΣA; 部分的句子大声说出来、写一遍。评分也更严：语法错一个、漏一个要点，写作分就往下掉一档。

⑤ 五类用法场景（配图记忆）
场景
例句
类型
1 不知道谁做的
My bike was stolen last week.
过去时被动
2 产品产地
This laptop was made in China.
过去时被动
3 该被做
Digital skills should be taught at school.
情态被动
4 能被做
It can be done in five minutes.
情态被动
5 流程步骤
The code is sent by text.
现在时被动
不及物动词无被动happen/arrive/sleep 没有宾语，不能变被动。
by 短语可省略只关心动作本身、不知道或不必说"谁做的"时，by 短语直接省略：My phone was made in China.（不必说 by someone）。这正是 B1 被动最常用的场景。
三步把主动句变被动① 宾语变主语；② 主动词变 be + 过去分词（be 随新主语和时态变）；③ 原主语放进 by...（可省）。例：Someone stole my bike. → My bike was stolen (by someone).
⑥ 中国学生 5 大高频错误诊断
错误 1：情态被动漏 be ✗ It can done. → ✓ It can be done.
错误 2：过去分词写成过去式 ✗ The email was send. → ✓ was sent.
错误 3：be 与主语不一致 ✗ The emails was sent. → ✓ The emails were sent.
错误 4：不及物动词变被动 ✗ The accident was happened. → ✓ The accident happened.
错误 5：buy 的分词错 ✗ The phone was buy by my dad. → ✓ was bought.（buy-bought-bought）

真题风格演练（PET 出题方式）
真题风格 · PET Reading Part 5 完形My phone (1) ______ (make) in China. It (2) ______ (give) to me by my grandma last year. Now it (3) ______ (use) every day. It can (4) ______ (repair) at any shop.
(1) is made；(2) was given；(3) is used；(4) be repaired（can be repaired）。
真题风格 · PET 选词My bike (steal) last week. → 正确形式
was stolen。last week 过去时，steal 的过去分词 stolen。
真题风格 · PET Writing Part 6 email写 2 句：你的手机哪造的、谁给你的。
参考：My phone was made in China. It was given to me by my parents for my birthday.
考场提分提醒完形三步：定时态（now→is/are，yesterday→was/were）、定 be 单复、写对过去分词。情态被动别忘了 be + 过去分词。
