英语伴随状语的特点是它所表达的动作或状态是伴随着句子谓语动词的动作而发生或存在的。伴随状语的逻辑主语一般情况下必须是全句的主语，伴随状语与谓语动词所表示的动作或状态是同时发生的。判断标准如下：
一、伴随状语的判断
1.一般在分词短语（现在分词表主动，过去分词表被动）前有逗号的是伴随状语。
例：The dog entered the room, following its master.
2.当主语处于两种或两种以上状态时，且动作的发生有同时性，但不同于时间状语从句的是伴随状语。
例：While I was writing my homework, my mother was cooking.
二、伴随状语的成分
使用分词形式，如：The dog entered the room, following its master.这条狗跟着主人进了屋。
用with复合结构，如：The little girls were playing with snow with their hands frozen red.小女孩们在玩雪，手都冻红了。
用独立主格结构，如：The little boy goes to school, the little dog accompanying him every day.这小孩每天去上学，那条小狗陪伴着他。
用形容词，如：Confident of the victory the players are fighting hard.运动员们对比赛夺胜满怀信心奋力拼搏。
用名词，如：He went away a beggar but returned a millionaire.他讨吃要饭离家，腰缠万贯回归。
用介词短语，如：The girl came back to her mother in tears.这女孩眼泪汪汪地回到母亲身边。
