案件开场：The Missing Buddhist Scripture Scroll
Last Sunday morning, Master Tang and his disciples（徒弟）were resting at a temple. At 10 o'clock, when they were preparing to continue their journey, they found the precious Buddhist scripture scroll with a golden pattern on it was gone! There was a crumpled（弄皱的）note on the stone table: "I’ll return it after reading."
Four disciples weren't with Master Tang then. The detective（侦探）, a temple monk, knew: the key was what each was doing at 10 o'clock.
嫌疑人陈述：
嫌疑人1：Sun Wukong
(
At 10 o'clock, I
was tidying
my golden cudgel by the door. I heard a soft sound from the backyard, then saw a yellow thing pass by, with a golden spot. I also found a piece of brown paper
with "hide it"
on the ground.
)
嫌疑人2：Zhu Bajie
(
I
was cleaning
the stone table at 10 o'clock. I saw Sha Wujing. He
was holding
a yellow cloth bag and running to the backyard. His hands
were wiping
something off his robe（长袍）.
)
嫌疑人3：Sha Wujing
(
At 10 o'clock, I
was looking
for my water bucket. I
was standing
by the window and saw Zhu Bajie
was bending
over the scripture scroll
’
s original place. Then he walked to the kitchen.
)
嫌疑人4：White Dragon Horse
(
I
was getting
my saddle（马鞍）from the stable（马厩）at 10 o'clock. I saw a yellow cloth bag under the stone chair, but I didn
’
t touch it. I
was picking
up a piece of brown paper with words on it when Sha Wujing passed by.
)
Zhu Bajie’s Supplementary Statement 猪八戒补充陈述（因贪吃露破绽）
At 10 o'clock, I was getting steamed buns from the kitchen. I didn’t see the scripture scroll! I was carrying my small cloth bag, but it’s tiny and it can’t hold a scroll. And I didn’t go to the backyard!
侦探线索：找多层破绽 Finding Multiple Loopholes
Sun Wukong found brown paper, and Bai Longma said he was picking up brown paper. What was on it
Zhu Bajie saw Sha Wujing was holding a yellow cloth bag and running to the backyard, but Sha Wujing said he was looking for a water bucket.
Sha Wujing saw Zhu Bajie was bending over the scripture scroll’s place, but Zhu Bajie only mentioned getting steamed buns.
The scroll had a golden pattern. Sun Wukong saw a "yellow thing with a golden spot," which matched the scroll.
真相揭晓：还原合作作案过程
Zhu Bajie and Sha Wujing finally admitted（承认）what they were doing.
(
At 10 o'clock, Zhu Bajie
_________
just
________（get）
steamed buns
. H
e
________________（take）
the scripture scroll first, then put it under the stone chair (the yellow thing Sun Wukong saw). He
_________
(write)
the note and dropped the brown paper
with "hide it" on it.
Sha Wujing
__________________（look for）
a water bucket
. H
e was taking the scroll from under the chair, putting it into his big yellow cloth bag (not the small one), and
__________________（run）
to hide it in the backyard (Zhu Bajie saw him). He wiped his robe because he
_________（touch）
the scroll’s dust.
)
They lied to cover each other. Zhu Bajie didn’t mention（提到）the scroll and Sha Wujing denied（否认）going to the backyard.

过去进行时
语法课堂
)
一、核心定义：什么是过去进行时？
过去进行时表示 “过去____________________或__________内正在进行的动作”，强调动作在过去某一刻 “__________” 的状态（而非完成结果）。
案件中的对应场景：比如 “上午10点时，孙悟空正在整理金箍棒”，“10点” 是过去特定时间，“整理金箍棒” 是此时正在做的动作，需用过去进行时。
At 10 o'clock, Sun Wukong was tidying his golden cudgel.
二、基础结构：过去进行时怎么变？
过去进行时的结构:
肯定句：主语 + ______________________________.
否定句：主语 + ______________________________.
一般疑问句：____________________ + 主语 + doing
三、核心用法：什么时候用过去进行时？
用法1：描述“过去特定时间点/段”正在做的动作
标志：句中会出现明确的过去时间点/段，如 “at 10 o'clock last Sunday morning, at that time yesterday, from nine to ten yesterday morning ...”。
At 10 o'clock, Sha Wujing was standing by the window.
用法2：描述“过去时间段内持续进行的动作”
标志：句中会隐含 “过去某一段时间”，而非单一时间点。
Master Tang and his disciples were resting at the temple last Sunday morning, when they were preparing to continue their journey.
用法3：描述“过去两个同时进行的动作”
标志：常用 “__________” 或 “__________” 连接两个动作。
While Sha Wujing was looking for his bucket, he saw Zhu Bajie bending over.
when/while在过去进行时中的区别
① when： 可引导「________动作」（瞬间完成，如 ring 响、see 看见、arrive 到达）；
可引导「________动作」（持续一段时间，如 read 阅读、wait 等待）。
接短暂动作：When the bell rang, I was having class.
接持续动作：When I was waiting for the bus, it began to rain.
② while： 只能引导「________动作」，while 本身强调 “动作的持续过程”。
√ While my mom was cooking, I was doing homework.
√ While we were walking in the park, we met our primary school teacher.
× While the door opened, she was watching TV.
