wake up 是动词,不可能带有后置定语。可以用如下方式改写:
改写为并列句:Beth Roche wakes up (and she knows) she can't feel sorry for herself, that she has to focus on rehabbing her ravaged left leg.
用 as(随着)改写为状语从句:(As she knows) she can't feel sorry for herself, that she has to focus on rehabbing her ravaged left leg, Beth Roche wakes up.
用while 改写:Beth Roche wakes up (while knowing) she can't feel sorry for herself, that she has to focus on rehabbing her ravaged left leg.
