学习如何正确使用英语的一般过去时，表达已完成的动作和历史事件。包括示例和练习。
什么是过去简单时？
过去简单时用于描述发生在过去并已完成的动作。对于规则动词，通常通过在动词的基本形式后加上 '-ed' 来构成，但不规则动词有不同的形式。
结构
要构成简单过去时，使用动词的过去时形式。
对于规则动词，过去形式是在动词的基本形式后加上 '-ed'。例如：
walk → walked (走 → 走了)
play → played (玩 → 玩了)
talk → talked (说话 → 说了话)
如果动词已经以 '-e' 结尾，只需在动词的基本形式后加上 '-d'。例如：
love → loved (爱 → 爱了)
free → freed (自由 → 自由了)
bake → baked (烤 → 烤了)
拼写
如果一个单音节的规则动词以元音 + 辅音结尾，则在添加 '-ed' 之前将最后一个辅音加倍以构成过去时。例如：
beg → begged (乞求 → 乞求了)
skip → skipped (跳过 → 跳过了)
不规则动词
不规则动词不遵循上述规则。这些动词在过去时形式上有不同的变化。例如：
go → went (做 → 做了)
bring → brought (带 → 带来了)
know → knew (知道 → 知道)
run → ran (跑 → 跑)
have → had (有 → 有)
do → did (再做 → 再做了)
'Be' 的过去时
'Be' 是英语中不规则动词之一，其过去时有两种形式：
be | |
|---|---|
I | was (是) |
you | were (是) |
he/she/it | was (是) |
we | were (是) |
you | were (是) |
they | were (是) |
I am a student. → I was a student.
我是一名学生。→ 我曾经是一名学生。
They are kind. → They were kind.
他们很善良。→ 他们很善良。
否定
对于过去简单时动词的否定，在动词的基本形式前添加 'did not' 或其简短形式 'didn't'：
I ran. → I did not run. (I didn't run.)
我跑了。 → 我没跑。
She walked. → She did not walk. (She didn't walk.)
她走了。 → 她没有走。
They talked. → They did not talk. (They didn't talk.)
他们说话了 → 他们没说话。
要否定 'be' 动词，只需在其过去形式（was/were）后加上 'not'。
I was happy. → I was not happy. (I wasn't happy.)
我很高兴 → 我并不高兴。
They were waiters. → They were not waiters. (They weren't waiters.)
他们是侍者。→ 他们不是侍者。
提问
要使用过去简单时形式构成疑问句，只需在句首使用 'did'，并将动词的过去形式改为其基本形式：
I ran. → Did I run?
我跑了。 → 我跑了吗？
She walked. → Did she walk?
她走路了。 → 她走路了吗？
要构成 'be' 动词的简单过去疑问形式，只需将动词放在句子开头，然后将主语放在其后。例如：
She was hungry. → Was she hungry?
她饿了。 → 她饿了吗？
They were at the mall. → Were they at the mall?
他们在商场。 → 他们在商场吗？
用途
过去简单时用于谈论：
过去已完成的动作
I had dinner at around 8 in the evening last night.
我昨晚大约8点吃了晚饭。
Mary graduated from college in 2013.
玛丽在2013年从大学毕业。
'-ed' 的发音
'-ed' 结尾有三种不同的发音：
/d/: 在所有元音音素和浊辅音（除了 /d/）之后 ⇒ walked (走了)
/t/: 在所有清辅音（除了 /t/）之后 ⇒ pressed (按下)
/ɪd/: 在 /d/ 和 /t/ 之后 ⇒ waited (等了)
