一、规则动词(Regullar Verbs)的过去式由“动词原形+-ed”构成，具体变化有：1.一般的直接在词尾加-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—movedsmile--smiled; hope--hoped.

注意：ie结尾动词,直接加d: died;tied.

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—trippedplanned;
