表示一般過(guò)去式的動(dòng)詞通常用動(dòng)詞的過(guò)去式形式來(lái)表示,而動(dòng)詞的過(guò)去式是在動(dòng)詞原形的基礎(chǔ)上變化的.動(dòng)詞的過(guò)去式可分為規(guī)則動(dòng)詞和不規(guī)則動(dòng)詞.規(guī)則動(dòng)詞的過(guò)去式變化如下：
（1）一般情況下,動(dòng)詞詞尾加 -ed ,如：
worked played wanted acted
（2）以不發(fā)音的 -e 結(jié)尾動(dòng)詞,動(dòng)詞詞尾加 -d,如：
lived moved decided declined hoped judged raised wiped
（3）以輔音字母 + y結(jié)尾的動(dòng)詞,把-y變?yōu)?i 再加-ed,如：
studied tried copied justified cried carried embodied emptied
（4）以一個(gè)輔音字母結(jié)尾的重讀閉音節(jié)動(dòng)詞,雙寫(xiě)詞尾輔音字母,再加 -ed,如：
stopped begged fretted dragged dropped planned dotted dripped
（5）注：不規(guī)則動(dòng)詞的過(guò)去式變化規(guī)律性不強(qiáng),須多加記憶.
