一般过去时的谓语动词要用动词的过去式。动词过去式的构成分规则变化和不规则变化两种形式,不规则变化通常需要逐个记忆,规则变化则遵循以下原则:
(1) 一般在动词后加-ed。如:playplayed, offeroffered, weighweighed, destroy destroyed, signsigned.
(2) 在以字母e结尾的动词后,只加-d。如:likeliked, provideprovided, hate hated, datedated。
(3) 在以辅音字母+y结尾的动词后,则改y为i,再加ed。如:supplysupplied, flyflied, study studied.
(4) 在以单短元音的重读闭音节结尾且,末尾只有一个辅音字母的动词后,双写最后一个辅音字母,再加-ed。如:planplanned, referreferred, regretregretted, banbanned.
