性质和特点:
动词的过去式用于一般进行时的句子中,表示过去的动作或状态。一般过去时通常带有表示过去时间状语的词,词组或从句。如 yesterday, the day before last, last week, two days ago,when I waked up 等。
词形变化:
1、在动词后面加ed(如果单词末尾是一个不发音的e,则只加d)。如:work--worked, move--moved, play--played, start--started, need--needed.
2、以辅音字母 + y结尾的动词,把y变为i 再加ed,如:study--studied try--tried
3、以一个辅音字母结尾的重读闭音节动词,双写这个辅音字母,再加 ed,如:stop--stopped, drag--dragged, drop--dropped
4、不规则动词的过去式。这须多加记忆。如:go - went,make - made, am/is--was, are--were
ed的读音:
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
不规则动词的记忆法:
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

含有be动词的一般过去时用法举例:
肯定句:I was late yesterday.
否定句:I wasn't late yesterday.
一般疑问句:Were you late yesterday?
肯定回答:Yes, I was.
否定回答:No, I wasn't.
特殊疑问词:Why were you late yesterday?
只含有实义动词的一般过去时用法举例:
肯定句:I drew a nice picture yesterday.
否定句:I didn't draw a nice picture yesterday. (实义动词不像be动词那样能带not,所以只能借助动词did。)
一般疑问句:Did you draw a nice picture yesterday? (问句需要谓语部分有一个词提到主语前面。而实义动词不像be动词那样能提前,所以只能借助动词did。特殊疑问句也是这样。)
肯定回答:Yes, I did.
否定回答:No, I didn't.
特殊疑问句:When did you draw a nice picture?
