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. go - went,make - made, get - got ,buy - bought ,come - came ,fly-flew ,is/am-was, are-were ,see-saw ,bring-brought,do-did,teach-taught, think-thought, are-were, say-said,sit-sat. read-read, spend-spent.(部分) 1 、規(guī)則動(dòng)詞:規(guī)則動(dòng)詞的過(guò)去分詞的構(gòu)成規(guī)則與規(guī)則動(dòng)詞的過(guò)去式的構(gòu)成規(guī)則相同.四點(diǎn)變化規(guī)則: (1)、一般動(dòng)詞,在詞尾直接加“ ed ”. work---worked---worked ,visit---visited---visited (2)、以“ e ”結(jié)尾的動(dòng)詞,只在詞尾加“ d ”. live---lived---lived , (3)、以“輔音字母 + y ”結(jié)尾的動(dòng)詞,將 "y" 變?yōu)?"i" ,再加“ ed ”. study---studied---studied ,cry---cried---cried , (4)、重讀閉音節(jié)結(jié)尾,末尾只有一個(gè)輔音字母,先雙寫(xiě)該輔音字母,再加“ ed ”. stop---stopped---stopped , drop---dropped--dropped 新陽(yáng)光教育提示:過(guò)去分詞和過(guò)去式的區(qū)別和用法相對(duì)來(lái)說(shuō)還是挺簡(jiǎn)單的,更多精彩內(nèi)容歡迎咨詢老師幫助解答。 |
