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:
studied tried copied justified cried carried embodied emptied
(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。
