截标日期怎么说？

I informed you deadline of tender has been prolonged.

释义：我正式通知您：投标截止日期已经延长。

赏析一： deadline “最后期限”

例如：Can they finish this before the deadline?

他们能不能在最后期限之前完成这项工作?

The deadline for making an application is next Friday.

申请于下星期五截止。

赏析二： prolong “延长”之意。

此处是被动语态， 变成主动就是prolong the tender

例如：prolong lives 延长生命
