自己做布贴:一句中译英.谢谢翻译

Whether the conference will be put off or not has not been decided.Please don't leave until you get the annoucement.

YOU CAN NOT LEAVE UNTIL YOU HAVE GOT THE INFORMATION,SINCE WHETHER THE MEETING IS PUT OFF HAS NOT BEEN DECIDED YET!绝对正确,应该比较纯正了

会议是否延期还未决定,请大家接到通知后离开
Whether or not the meeting will be postpone, has not been decided yet, so please leave after everybody is informed.

但是英语方面,相信我没错的.
我能想大家保证,我绝对(100%)正确!
