Answer 1

this phenomenon is very dangerous to the whole society。中to the whole society是状语

Answer 2

补语 to the whole society 对于整个社会

advantages to (to 是介词， 介词+名词）

追问

to he whole society 是作什么的补语。
to reducing the numbers of private cas在整个句子中的成分是什么，谢谢。

Answer 3

to 的用法：
1）to do sth. 不定式
2） to sth. / doing sth. 介词短语

问题里的两句都是第二种用法。

1、This phenomenon is very dangerous. 主系表
to the whole society 介词短语作状语，表示对象，对于整个社会来说，（这种现象很危险）。

2、there are advantages. 主系表
to reducing the numbers of private cars 介词短语作状语，表示对象，对于减少私家车数量这件事来说，（是有好处的）。

advangage常见的固定搭配有：
There are advantages to sth./ doing sth.
One of the advantages of sth./ doing sth. is...
It is an advantage to do sth.

Answer 4

the whole society介词to 后的宾语
to reducing the numbers of private cars是补语具体解释advantage

Answer 5

第一个问题中的to the whole society 做介词to 的宾语。
第二个问题我认为there be句型是倒装句，to reducing the number of private cars 做advantages 的定语。

Answer 6

标语补足语
