什么单词分词形式双写有什么规律?

网友回答

1.闭音节：闭音节是以一个元音字母加一个或几个辅音字母结尾的音节.例如：not,thank,ten,am,six等.重读闭音节就是所谓的元音字母不是发它本身的字母音.
因此,mix是一个重读闭音节单词.
2.以重读闭音节结尾,末尾只有一个辅音字母的动词,要双写这一辅音字母,再加-ing/ed.例如：
bag[bæg],其现在分词,过去式,过去分词为:
baging - bagged - bagged
mix[miks],看看它的音标,在元音字母i的后面还有ks两个辅音节,而bag[bæg],在其元音字母a后面只有一个辅音节g.
所以,mix的现在分词,过去式,过去分词为:
mixing - mixed - mixed
同类的单词如: box ( boxing - boxed - boxed )
======以下答案可供参考======
供参考答案1:
以重读闭音节结尾且结尾只有一个辅音字母的，双写这个辅音字母 ,也就是最后一个字母和倒数第三个字母中间夹一个元音
供参考答案2:
动词过去式,过去分词不规则变化
