“不好意思请确认下,寄给总部的那些文件是否也需要盖章,我有点忘记了,不好意思阿”
你好!我是英语历腔粗师范学校毕业肢镇的,希望我可以为你排忧解难!
你的例圆闷句可以翻译为:
Excuse me ,would you please confirm that whether the documents which will send to the general headquarter need stamp ?
正解如下

I'm sorry ,please confirm whether those documents to be sent to the headquarters also need to be stamped, I just forget it, I'm so sorry.
i am sorry, for i am still not sure whether the documents sent to the headquarter need to be sealed or not.
I'm sorry ,please confirmation those documents which sent to the headquarters whether need to seal, I am a bit forgotten,i'm sorry
