关于一个英语长难句的分析中,这里的逗号表示什么含义?Tobacco taxes improve public health,they raise money and most particularly,they deter people from taking up the habit as teens,which is when nearly all smokers are addicted.这里的每一个逗号都表示并列的含义吗?they raise money and most particularly,这里的and 后面怎么会加一个副词性的东西呢？

Tobacco taxes improve public health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted.

这里的每一个逗号都表示并列的含义吗?they raise money and most particularly, 这里的and 后面怎么会加一个副词性的东西呢?

第一句 Tobacco taxes improve public health 是一句完整句,能够独立自成一句,若後面跟著的句子没有许接词的话,便要加一个逗号(是代替连接词的作用),这是英语语法之一.而随後 most particularly又加上一个逗号则是长句稍为一顿的作用.最後的一个逗号则又是英语语法之一: which 之前要加逗号(而 that 则不用加).
