(1) 一般在动词后加-ed。如：play—played, offer—offered, weigh—weighed, destroy— destroyed, sign—signed.
(2) 在以字母e结尾的动词后，只加-d。如：like—liked, provide—provided, hate — hated, date—dated。
(3) 在以“辅音字母+y”结尾的动词后，则改y为i，再加—ed。如：supply—supplied, fly—flied, study— studied. (from www.yygrammar.com)
(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：plan—planned, refer—referred, regret—regretted, ban—banned.
四、特别说明
有些动词的过去时，如：expect, hope, intend, plan, wanted 等一般过去时，后接不定式的完成时;或它们的过去完成时接不定式的一般式，都可表示过去未曾实现的意图、打算或希望。
如：I hoped to have been invited to his wedding party. —I had hoped to be invited to his wedding ceremony. 我本希望他来邀请我参加他的婚礼。
I intended to have joined their games. —I had intended to join their games. 我本打算参加他们的比赛。
