2023年初中英语一一般过去式构成

一般过去式构成：表示一般过去式的动词通常用动词的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。规则动词的过去式变化如下： 一般情况下，动词词尾加 -ed 。

worked, played, wanted, acted

以不发音的 -e 结尾动词，动词词尾加 -d。

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

以辅音字母 + y结尾的动词，把-y变为-i 再加-ed。

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

以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加 -ed。

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

不规则动词的过去式变化规律性不强，须多加记忆。

go - went， make - made， get - got

buy - bought， come - came， fly-flew

其结构是"主语+动词的过去式"。be动词的过去式为was, were;行为动词的过去式有规则变化和不规则变化两种，规则变化有以下几种情况：1)直接在动词原形末尾加-ed. e.g. work-----worked; ask------asked; 2)以e结尾的动词只加-d. e.g. arrive-----arrived; like-----liked.3)末尾只有一个辅音字母的重读闭音节,应先双写这个辅音字母,再加-ed. e.g. shop-----shopped; 4)以"辅音字母+y"结尾的动词,先把y变成i,再加-ed. e.g. carry----carried; study------studied.有些动词变过去式是不规则的,e.g. fly------flew; break-----broke; teach-----taught. 这些需要象生单词一样记住. 其句式变化分为两种情况1)含有be动词的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行为动词的变否定句要在行为动词前加助动词didn't.,同时把动词变成原形; 变一般疑问句,在句首加助动词did,同时把动词变成原形. 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?
