动词的过去式有哪些规律?
展开全部
规则动词词尾加-ed有三种发音规律:
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。

不规则动词的过去式大体上归纳有以下六条:
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。
