动词过去式变化规则有哪些，要三个(五年级英语的)还有例子 格外的:ed或d的发音

Answer 1

动词过去式变化规则主要包括规则动词和不规则动词。规则动词的过去式变化有以下几种情况：

(1) 大多数情况下，动词词尾加 "ed"，例如：work→worked; play→played; want→wanted; act→acted

(2) 以不发音的 "e" 结尾的动词，在词尾加 "d"，例如：live→lived; move→moved; decide→decided; decline→declined; hope→hoped

(3) 以辅音字母 "y" 结尾的动词，将 "y" 变为 "i" 再加 "ed"，例如：studied→studied; tried→tried; copied→copied; justified→justified; cried→cried; carried→carried; embodied→embodied; emptied→emptied

(4) 以一个辅音字母结尾的重读闭音节动词，双写词尾的辅音字母，再加 "ed"，例如：stopped→stopped; begged→begged; fretted→fretted; dragged→dragged; dropped→dropped; planned→planned; dotted→dotted; dripped→dripped

对于不规则动词，过去式的形成规律性不强，需要记忆，例如：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; say→said; sit→sat

在发音方面，(1) 至 (4) 条中的动词过去式通常有改变，例如 /d/、/t/、/id/ 等。而不规则动词的过去式的发音则有所不同，但有些遵循一定的规律，例如：make→made; get→got; buy→bought; come→came; fly→flew; bring→brought; teach→taught; think→thought; say→said; sit→sat; read→read; spend→spent; eat→ate; give→gave; tell→told; write→wrote; feel→felt; find→found; hear→heard; know→knew; put→put; grow→grew; take→took; catch→caught; come→came; become→became; swim→swam; sweep→swept; sing→sang; draw→drew。

综上所述，动词过去式的形成规律主要分为规则动词和不规则动词，各自有其变化模式及发音特点。记忆并理解这些规则对于掌握英语语法至关重要。
