一般過去式 表示過去的動作和狀態(tài)。

I met him yesterday. 昨天我碰見了他。

一般過去時的構(gòu)成如下：

肯定式 疑問式 否定式 疑問否定式

I worked Did i work? I didn’t work Did i not work?

He(she it) Did he (she it) He(she it) Did he(she it)

worked work? didn’t work not work?

We worked Did we work? We didn’t work Did we not work?

You worked Did you work? You din’t work Did you not work?

They worked Did they work? They didn’t work Did they not work?

一般過去式構(gòu)成： 表示一般過去式的動詞通常用動詞的過去式形式來表示，而動詞的過去式是在動詞原形的基礎(chǔ)上變化的。動詞的過去式可分為規(guī)則動詞和不規(guī)則動詞。規(guī)則動詞的過去式變化如下： 一般情況下，動詞詞尾加 -ed 。

worked, played, wanted, acted

以不發(fā)音的 -e 結(jié)尾動詞，動詞詞尾加 -d。

Lived, moved,decided, declined, hoped, judged, raised, wiped

以輔音字母 + y結(jié)尾的動詞，把-y變?yōu)?i 再加-ed。

studied, tried, copied , justified, cried, carried, embodied, emptied

以一個輔音字母結(jié)尾的重讀閉音節(jié)動詞，雙寫詞尾輔音字母，再加 -ed。

stopped, begged, fretted, dragged, dropped, planned, dotted, dripped

不規(guī)則動詞的過去式變化規(guī)律性不強，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+動詞的過去式"。be動詞的過去式為was, were；行為動詞的過去式有規(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）直接在動詞原形末尾加-ed. e.g. work-----worked; ask------asked; 2）以e結(jié)尾的動詞只加-d. e.g. arrive-----arrived; like-----liked.3)末尾只有一個輔音字母的重讀閉音節(jié),應(yīng)先雙寫這個輔音字母,再加-ed. e.g. shop-----shopped; 4)以"輔音字母+y"結(jié)尾的動詞,先把y變成i,再加-ed. e.g. carry----carried; study------studied.有些動詞變過去式是不規(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)含有行為動詞的變否定句要在行為動詞前加助動詞didn’t.,同時把動詞變成原形; 變一般疑問句,在句首加助動詞did,同時把動詞變成原形. 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?
