on the other hand 是否一定和on the one hand 同时使用

on the other hand 是否一定和on the one hand 同时使用

前一段用 on the one hand, 后一段最好用 on the other hand, 但也有人用别的词来代替，比如: On the one one hand we must clean up the city, but we must also eradicate poverty.

前一段没有on the one hand，后一段可以有on the other hand.
比如：I would really like to go for a long walk tonight. On the other hand, there's still lots of work to be done.

这样的句型 on the one hand，on the other hand 都需要：
There is a political struggle going on with A on the one hand and B on the other.

I hope this is enough evidence for you. ^_^

不是的,也可以用其他表示"另一方面,另一边"意思的词语.学语言要灵活运用,多看写外国电影哦.

首先，不是on the one hand，是on one hand
第二，on one hand……，on the other hand说得上是固定搭配了，当然能用。证据嘛，一些文章里找找，但这两个东东我都用了N年了，不会错。
