英语动词过去时变化规律,

英语动词过去时变化规律,
规则动词的过去式由“动词原形+-ed”构成,具体变化有:
1.直接在词尾加-ed.如:want—wanted,work—worked,need—needed,clean—cleaned
2.以不发音的e结尾的在词尾加-d.如:like—liked,live—lived,use—used,move—moved
3.以一个元音字母加一个辅音字母结尾的重读闭音节动词,先双写结尾的辅音字母,再加-ed.如:stop—stopped,trip—tripped
4.以辅音字母加y结尾的动词,先把y变成i,再加-ed.如:study—studied,carry—carried,hurry—hurried,marry—married
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
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

(1)一般情况下,动词词尾加 -ed ,如:
worked played wanted acted
(2)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
(3)以辅音字母 + y结尾的动词,把-y变为-i 再加-ed,如:

(4)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
(5)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 ,is/am-was, are-were ,see-saw ,bring-brought,do-did,teach-taught, think-thought, are-were, say-said,sit-sat,make-made
[编辑本段]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。
(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。
时间标志: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。
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。
