关于on the one hand和on the other hand的造句和用法
比如我说On the one hand this activity is interesting,on the other hand it makes people happy.这样造行不?,我还想知道on the one hand和on the other hand是放在句首还是句末还是句中,如果说This activity is interesting on the one hand,it makes people happy on the other hand .还有This activity on the one hand is interesting,it on the other hand makes people happy.这3句的位置哪句是对了,还是都可以?
