"one the one hand，on the other hand"句式怎么用

一、"one the one hand，on the other hand"应改为on the one hand，on the other hand。
二、on the one hand…, on the other hand…一方面……，另一方面……
大家经常误以为“on the one hand”和“on the other hand”之间有递进或者并列的关系。事实上，这一对短语一般是用于提出两个相反的事物和看法。
例句
On the one hand, I want to go to the party, but on the other hand I ought to be studying.
一个想要办理出国的人看到这样的现状，十分困惑不解，
On the one hand, a lot of people going to the US, but on the other hand, a lot of people coming back from there.
一方面，许多人前往美国；另一方面，很多人又从那回来。

应该是：on（不是one) the one hand,on the other hand
有时省略：
on (the) one hand...on the other (hand)
该连接词语用于对比不同的事物,表示“一方面…,另一方面….”
On the one hand,she taught English; on the other hand she learned Chinese.
她一方面教英语,一方面学习汉语.
On ( the ) one hand I admire your ability,but on the other ( hand ) I distrust your judgment.一方面我钦佩你的才能,但另一方面我不相信你的判断力.
