來(lái)源:網(wǎng)絡(luò)來(lái)源 作者:中考網(wǎng)編輯 2019-09-17 14:31:48
中考網(wǎng)整理了關(guān)于2020年中考英語(yǔ)知識(shí)點(diǎn)之一般過(guò)去式構(gòu)成 ,希望對(duì)同學(xué)們有所幫助,僅供參考。
一般過(guò)去式構(gòu)成: 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: 一般情況下,動(dòng)詞詞尾加 -ed 。
worked, played, wanted, acted
以不發(fā)音的 -e 結(jié)尾動(dòng)詞,動(dòng)詞詞尾加 -d。
Lived, moved, decided, declined, hoped, judged, raised, wiped
以輔音字母 + y結(jié)尾的動(dòng)詞,把-y變?yōu)?i 再加-ed。
studied, tried, copied , justified, cried, carried, embodied, emptied
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。
stopped, begged, fretted, dragged, dropped, planned, dotted, dripped
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
其結(jié)構(gòu)是"主語(yǔ)+動(dòng)詞的過(guò)去式"。be動(dòng)詞的過(guò)去式為was, were;行為動(dòng)詞的過(guò)去式有規(guī)則變化和不規(guī)則變化兩種,規(guī)則變化有以下幾種情況:1)直接在動(dòng)詞原形末尾加-ed. e.g. work-----worked; ask------asked; 2)以e結(jié)尾的動(dòng)詞只加-d. e.g. arrive-----arrived; like-----liked.3)末尾只有一個(gè)輔音字母的重讀閉音節(jié),應(yīng)先雙寫(xiě)這個(gè)輔音字母,再加-ed. e.g. shop-----shopped; 4)以"輔音字母+y"結(jié)尾的動(dòng)詞,先把y變成i,再加-ed. e.g. carry----carried; study------studied.有些動(dòng)詞變過(guò)去式是不規(guī)則的,e.g. fly------flew; break-----broke; teach-----taught. 這些需要象生單詞一樣記住. 其句式變化分為兩種情況1)含有be動(dòng)詞的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行為動(dòng)詞的變否定句要在行為動(dòng)詞前加助動(dòng)詞didn't.,同時(shí)把動(dòng)詞變成原形; 變一般疑問(wèn)句,在句首加助動(dòng)詞did,同時(shí)把動(dòng)詞變成原形. e.g. I bought a gift for my mum yesterday. I didn't buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday?
