No one (cares about) if he (appears) at the meeting next year or not.If (it happens) he will (be made to) apologize for his careless comments. UAq%Y8KA  
沒人關心他是否會在明年的會議上露面。如果他來了，就不得不為自己的出言不慎而道歉。 l9X\\uG&

原來的句子是“如果發生了”，，，那前一句有兩種情況。。 Yab=p 9V;;  
一種是他會來，一種是他不來。。 zr5(nAl  
你怎么知道是哪一種發生了。 ,t=12R]>  
所以我覺得為了意思的通順，，不產生歧義，，應該改成“如果他來了”
