什么叫做过去式(英语),怎样分辨?
过去式是用来表达动词的“过了”、“完了”,“结束了”等意思,和现在的状态没有关系.
一般过去式 表示过去的动作和状态.I met him yesterday.昨天我碰见了他.
一般过去式构成：表示一般过去式的动词通常用动词的过去式形式来表示,而动词的过去式是在动词原形的基础上变化的.动词的过去式可分为规则动词和不规则动词.规则动词的过去式变化如下：
一般情况下,动词词尾加 -ed ,如：
worked played wanted acted
以不发音的 -e 结尾动词,动词词尾加 -d,如：lived moved decided declined hoped judged raised wiped
以辅音字母 + y结尾的动词,把-y变为-i 再加-ed,如：
studied tried copied justified cried carried embodied emptied 以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,再加 -ed,如：stopped begged fretted dragged dropped planned dotted dripped 注：不规则动词的过去式变化规律性不强,须多加记忆.
go - went make - made get - got buy - bought come - came fly-flew
一般过去式的用法：
1) 表示过去某一时刻或某一段时间内所发生的动作或情况,通常一般过去式带有表示动作时间状语的词,词组或从句,如 yesterday,the day before last,last week,two days ago 等,上下文清楚时可以不带时间状语.
I worked in that factory last year.
去年我在那一家工厂工作.
I went to the Tian Long Mountain yesterday.
昨天我们去了天龙山.
举几个动词变过去是的例子：
go-went
eat-ate
ride-rode
play-played
sing-sung
put-put
jump-jumped
dance-danced
sweep-sweeped
get-got
do-did
is-was
see-saw
2.
一般过去时态：表示过去某一时间所发生的动作或存在的状态.谓语动词要用一般过去式.经常与yesterday（昨天）,last week（上周）,last month（上个月）,last year（去年）,two months ago（两个月前）,the day before yesterday（前天）,in 1990 (在1990年),in those days （在那些日子里）等表示过去的时间状语连用.
如：I was born in 1990.(我出生在1990年).
When did you go to the park?（你是什么时候去的公园）.
I went to the park last week.（我是上周去的公园）
在上面的句子中第一句属于be动词的一般过去时态；第二句和第三句属于实义动词的一般过去时态.
1． Be 动词的一般过去时态
在没有实义动词的句子中使用be动词,am is 的过去式为was; are的过去式为were.
构成：肯定句：主语+was (were) +宾语
如：I was late yesterday.（昨天我迟到了.）
否定句：主语+was (were) +not+宾语
如：We weren't late yesterday.(我们昨天没迟到)
疑问句：Was (Were) +主语+宾语
如：Were you ill yesterday?（你昨天病了吗?）
肯定回答：Yes,I was.(是的,我病了.)
否定句：No,I wasn't.(不,我没病.)
特殊疑问句：特殊疑问词+was (were) +主语+宾语
如：When were you born?你是什么时候出生的?
《新概念2》里的原文都是过去式的,例如第一课：
A private conversation
Last week I went to the theater.
I had a very good seat.
The play was very interesting.
I did not enjoy it.
A young man and a young woman were sitting behind me.
They were talking loudly.
I got very angry.
I could not hear the actors.
I turned round.
I looked at the man and the woman angrily.
They did not pan any attention.
In the end,I could not bear it.
I turned round again.
“I can’t hear a word!” I said angrily.
“It’s none of your business,” The young man said rudely.“This is a private conversation!”
New words and expressions.
Conversation
Theatre
I got very angry.
It’s none of your business.
还有等等许多文章.
规则动词词尾加-ed有三种读音：
1.在清辅音后读作[t].如：asked,helped,watched,stopped
2.在浊辅音和元音后读作[d].如：enjoyed,studied,moved,called
3.在t / d后读作[id].如：wanted,needed
[三级解密]不规则动词的过去式见课本后的不规则动词表.大体上归纳有以下六条记忆法：
1.以t结尾的词,过去式与原形相同.如：put—put,let—let,cut—cut,beat—beat
2.以d结尾的词,把d变成t.如:build—built,lend—lent,send—sent,spend—spent
3.以n结尾的词,在词后加t.如：mean—meant,burn—burnt,learn—learnt
4.以ow / aw结尾的词,把ow / aw变成ew.如：blow—blew,draw—drew,know—knew,grow—grew
5.含有双写字母的词,将双写改为单写,在词尾加t.如：keep—kept,sleep—slept,feel—felt,smell—smelt
6.含有元音字母o / i的词,将o / i变成a.如：sing—sang,give—gave,sit—sat,drink—drank

过去式是用来表达已发生的动词形式。有三种情况：动词的过去式（用来表达过去的动作）；不定式的过去式（表示动作早于谓语动词）；现在分词的过去式（同不定式）。

过去发生的事情，用过去的时态表现出来，一般都在动词上面做变化。具体动词怎么变，你刚开始学这个的话最好先背动词变化的表。
