【考点一】一般过去时的特殊疑问句 【考点二】一般过去时的肯定句
【考点三】一般过去时的一般疑问句及回答 【考点四】to do 不定式表目的 & can/could 表能力
考点一:一般过去时的特殊疑问句
—What did you do during the winter holiday?
—I visited the Terracotta Army with my parents.
解析:这是一组询问过去行为的基础对话,核心考查一般过去时特殊疑问的句型结构与用法。
(一)对动作提问:特殊疑问词 + did + 主语 + 动词原形 + 其他?
1.助动词did:无单复数变化,用于一般过去时实义动词疑问句
2.动词必须用原形,不可使用过去式
(二)对状态提问:特殊疑问词 + was/were + 主语 + 其他?
3.单数主语用was,复数主语用were
4.无需加助动词 did
【大显身手】
一、单项选择题。

—I visited the old village.
A. What B. When C. Where D. Why

本句应用
关键规则

【大显身手】
一、判断题(判断句子是否符合规则,对打 “√”,错打 “×”)
1.People carry silk along the Silk Road in the past.( )
2.The old castle was built 500 years ago.( )
3.They were very tired after the long journey.( )
4.He find an ancient pot yesterday.( )
5.The sun rose in the east many years ago.( )
考点三:一般过去时的一般疑问句及回答
—Did you go to the ancient town last winter?
—Yes, I did.
解析:用于询问过去是否发生某动作、存在某状态,3 步变一般疑问句。
—Was the old tower famous before?
—Yes, it was.
1.找助动词 /be 动词:实义动词用 did,be 动词用 was/were
2.助动词 /be 动词提前:放句首,首字母大写
3.句末变问号:其他单词顺序不变
回答套路:Yes/No + 主语 + 助动词 /be 动词
疑问句例子
肯定回答
否定回答
Did you visit it?
Yes, I did.
No, I didn’t.
Was it old?
Yes, it was.
No, it wasn’t.
Were they busy?
Yes, they were.
No, they weren’t.
【易错点】
did 后必须接动词原形,不能用过去式;was/were 不与 did 混用。
【记忆口诀】
过去疑问分两类,实义动词 did 带头,
be 动提问提前走,Yes/No 回答跟着守。
( )1. —______ you visit the museum yesterday?
—Yes, I did.
A. Do B. Did C. Are D. Were
( )2. —______ the old bridge built 300 years ago?

考点四:to do 不定式表目的 & can/could 表能力
They worked hard to save the wallpaintings.
We can see old buildings. People could not take photos before.
解析:本考点包含两个核心语法,适配单元历史保护、过去能力描述场景。
1.to do 表目的:动词 + to + 动词原形,表 “为了做某事”
2.can/could 表能力:can 表现在能力,could 表过去能力,后接动词原形
语法类型
核心结构
本单元例子
关键规则

动词 + to + 动词原形
work hard to save
to 后接动词原形
can 表现在能力
主语 + can + 动词原形
We can see
现在能力用 can
could 表过去能力
主语 + could + 动词原形

【易错点】
to 后不加 ing/es;could 后接动词原形,否定式 couldn’t。
【记忆口诀】
目的状语 to 加原,现在能力 can 来连,
过去能力 could 换,否定直接 n’t 添。
