◆ 原句再现
◆ 一般过去时的含义：过去某个时间发生的动作或状态；过去习惯性/经常性的动作或行为
●过去某个时间发生的动作或状态，这时句中往往有具体的过去时间状语，请观察以下句子
a. Mr. Black sold his mountain bike yesterday.
b. The teacher was in the classroom just now.
c. Mary left school at nine this morning.
d. They went abroad last week.
a. They always went to work on foot last year．
b. He was often late for class last week.
c. The boy usually got up at six last month.
d. These students sometimes went to school by bus a year ago.
●过去习惯性/经常性的动作或行为,这时同样会出现表示过去的时间状语或以过去为背景，请观察以下句子
● used to do/to be 这一结构只表示过去经常做某事或存在的状态
，与现在已无关系，即现在已经不那样了，to为不定式，后接动词原形, 请观察以下句子
a. My family used to spend our vacation at the seaside.
(暗示现在不再去海边度假了)
b. His father used to smoke.
(暗示他父亲现在不抽烟了）
c. We used to swim in the river when we were children.
(暗示现在不在那条河里游泳了）
d. My mother used to stay up when I was a child.
(暗示现在母亲不再熬夜了）
e. His brother used to be a doctor.
(暗示现在他弟弟不再是医生了)
● would do sth. 也表示过去经常发生的动作，它与 used to do/to be 的区别是：这种行为或状态现在可能没有了也可能依然存在；would后的动词一般为动态动词，而非静态动词，请观察以下句子
a. The old man would talk and talk for several hours.
b. These children would come to my house at weekends.
◆ 一般过去时的句式变化
a. They often came to help us in those days.
b. She was tired all the time last year.
c. We were sent here three years ago.
● 肯定句:主语+动词过去式+其它，请观察以下句子
●否定句：主语 + didn‘t + 动词原形+其它, 请观察以下句子
a. I didn’t know you like coffee.
b. They were not doctors then.
c. She didn’t go to Paris with her husband ten years ago.
a. She did some cleaning last week.
→Did she do any cleaning last week
b. These workers were late for work yesterday.
→Were these workers late for work yesterday
●一般疑问句:
※ Did +主语 + 动词原形 + 其它 +
※ Was/Were +主语 + 表语 +
请观察以下句子
● 特殊疑问句:
※ 疑问词 + was/were +主语 + 其它 +
※ 疑问词 + did +主语 +动词原形 +其它 +

◆动词过去式的构成
● 规则动词过去式的构成：
※ 通常在动词末尾加 ed：talk→talked; work→worked
※ 以不发音字母的 e结尾的动词末尾只加d ：like→liked ; arrive→ arrived
※ “辅音字母+ y ”结尾的动词, 先将 y 变为 i, 再加 ed ： study→studied ; carry→carried
● 系动词 be 的过去式有两种形式：was 和 were, 其中was 是 am和 is的过去式，were 是 are的过去式
1. My father ______ ill yesterday.
A. isn't B. aren't C. wasn't D. weren't
2. ______ your parents at home last week﹖
A. Is B. Was C. Are D. Were
