The speaker makes it sound so difficult to ignore the pain of regret that it might well be possible that nobody alive has the fortitude to suppress the ache.
请问老师:
1 第一个it是形式宾语指代 to ignore the pain of regret吗?
2 第一个that是so…that结构,引入结果状语吗?
3 第二个it是形式主语指代 that nobody alive has the fortitude to suppress the ache吗?
