1)用动词的过去式。作谓语的行为动词的词尾变化如下:

重读闭音节结尾的单词,末尾只有一个辅音字母 | 双写词尾字母+ed |
一般过去时对谓语动词的要求
一般过去时用动词的过去式构成。即一般过去时的谓语动词要用动词的过去式。动词过去式的构成分规则变化和不规则变化两种形式,不规则变化通常需要逐个记忆,规则变化则遵循以下原则:
(1) 一般在动词后加-ed。如:play—played, offer—offered, weigh—weighed, destroy— destroyed, sign—signed.
(2) 在以字母e结尾的动词后,只加-d。如:like—liked, provide—provided, hate — hated, date—dated。
(3) 在以“辅音字母+y”结尾的动词后,则改y为i,再加—ed。如:supply—supplied, fly—flied, study— studied. (ammar)
(4) 在以单短元音的重读闭音节结尾且,末尾只有一个辅音字母的动词后,双写最后一个辅音字母,再加-ed。如:plan—planned, refer—referred, regret—regretted, ban—banned.
2)一般过去时态的肯定句、否定句和疑问句形式(以be和like为例):
主 语 | 肯 定 式 | 否 定 式 | 疑 问 式 |
第一、二人称和第三人称复数以及名词复数 | I was a student. We/You/ They were students. He/ She was a student. I / We/ You/ They/ liked music. Many people liked music. | I was not a student. We/You/ They were not students. He/ She was not a student. I / We/ You/ They/ didn’t like music. Many people didn’t like music. | weigh的用法 Were you a student. Were you/ they students Was he/ she a student Did you/ they like music Did many people like music? |
3)一般过去时的用法:
1. 过去发生的动作。例如:
The police stopped me on my way home last night.
2. 过去存在的状态。例如:
They weren't able to come because they were so busy.
3. 常用于一般过去时的时间状语:
yesterday,three months ago,last year,in 1979,often,always等。
3 用法说明
1)表示在过去某个时间所发生的动作或所处的状态。 常与yesterday, last week, in 1989, just now, a moment ago, the other day等连用。
如:He was here just now. 他刚才还在这里。
What did you do yesterday? 你昨天做了什么事?
2)在过去一段时间内的经常性或习惯性动作。

注:表示过去经常发生的动作还可用used to 和would。

3)表示主语过去的特征或性格。

5)一般过去时有时可以表示现在,多与 want, hope, wonder, think, intend 等动词连用,使语气更委婉。
如:I wondered if you could help me. 不知你能不能帮我一下。
有时用一般过去时也是时态一致的需要。
如:I didn’t know you were here. 没想到你在这里。
注意:
1. 表示一系列的动作,尽管有先后,都用一般过去时,最后两个动词之间用and连结。如: He opened the door, rushed out and then disappeared. 他打开门,冲了出去,然后就消失了。
2. 注意在语境中理解“我刚才/原来还不……”。如:
—Your phone number again? I didn’t quite catch it. —It’s 2566666. 请再说一次你的电话号码,好吗?我刚才没听清楚。是2566666。
特别说明
有些动词的过去时,如:expect, hope, intend, plan, wanted 等一般过去时,后接不定式的完成时;或它们的过去完成时接不定式的一般式,都可表示过去未曾实现的意图、打算或希望。如:
I hoped to have been invited to his wedding party. —I had hoped to be invited to his wedding ceremony. 我本希望他来邀请我参加他的婚礼。
