延期的话给编辑回信吧,格式如下,请参考,一般理由充分的话,编辑会理解的Dear ×××It is so nice to receive this positive decision letter, however, due to my predefined academic schedule, I will be out of hospital for two months, therefore, May I request that the time available for resubmission be extended to 12 weeks? please let me know if it is ok?
