前面我们写过不少英文核心论文写作、选刊、返修回复模板的干货，这篇说一下返修延期的问题，投稿后收到大修比较常见，主编会根据审稿人意见给出1-3个月不等的返修时间，但如果修改意见太难、意见太多、补实验周期长等原因导致返修时间不够用怎么办？可以申请延期，继续修改。
沟通延期主要提到的几点：对编辑和审稿人表示感谢；已经在抓紧修改了，但是一些问题需要补实验/提升语言/请教专家查阅文献，为了确保修改质量，需要更多的时间；说明要延期多久。只要时间合理，期刊都会酌情满足。
主题：Asking for extending the deadline [ID-XXX]
模板1：快到截止日期，被期刊催稿
感谢您给我们机会大修，将我们的手稿提高到适合在贵刊发表的水平。然而我们需要一个延长期限以便进一步修订。您能把截止日期延长到XXX吗？
Dear XXX
Thanks for your email informing us that our manuscript entitled "XXX" (Manuscript ID: XXX ) is due for revision. We appreciate that you gave us a chance of major revision to improve our manuscript to a level suitable for publication in your journal. However, We need a new deadline extension for further revision. Could you please extend the deadline to XXX? Thanks for your help.
Best regards,
XXX
模板2：实验没补完
根据审稿人的建议和意见，我们需要在手稿中补充更多的实验。我们恐怕无法在截止日期（XXX天内）之前重新提交修订。因此，如果您能将截止日期（XXX）延长，我们将不胜感激，以便我们更恰当地修改手稿。
Dear XXX,
We are writing to you regarding our submitted article entitled“XXX”(Manuscript ID-XXX), which is currently under revision. According to the reviewers’ suggestions and comments, we need to conduct more experiments for our manuscript.
We are afraid that we are not able to re-submit the revisions by the deadline (within XXX days). Therefore, we will be most grateful if you could extend the deadline, preferably, for XXX, so that we can revise the manuscript more appropriately.
Thank you in advance for your understanding and kind assistance, and look forward to receiving your advice soon.
Kind regards,
XXX
模板3：
非常感谢您对这份手稿的仔细考虑。为了按照审稿人的要求全面修改稿件，我们需要更多的时间来完成这次修改。因此，我们诚挚地要求额外的XXX天时间来修改手稿。如果可能的话，请告诉我们。
Dear XXX,
Thank you very much for your kind consideration of this manuscript . In order to fully revise the manuscript as required by referees, we need more time to finish this revision. So, we cordially ask for additional XXX days time for revising the manuscript. Please let us know if this is possible.
Kind regards,
XXX
注意1. 不要到了截止期限才去申请延期，编辑如果看到的不及时，来不及修改系统设定的期限，有可能会自动清除稿件的修改状态，只能重新走流程。2. 申请延期的原因一定要充分。3. 尽量在申请到的延期时间内完成返修，二次申请延期很容易被拒稿。4.有些比较友好的期刊超过返修期限，也不会关闭系统，期刊会发个信询问，及时回复沟通延期也可以。不过即使投稿系统关闭，有足够理由也可以请求编辑重开投稿系统上传修改稿。
