韦氏高阶： often used in the form granted or granting to introduce a clause

Granted that she's been under a lot of stress lately, her behavior is still surprising. [=I admit that she has been under a lot of stress lately, but I am still surprised by her behavior]

Even granting that you may be right [=even if you are right], I still think we need to consider other solutions.

所以，把granted和grating分析为引导让步状语从句的连词是最简单的，不必再做过细的分析。
