句子有being問題

Susan has come to realize the importance of being diligent

diligent前面為何要有being?
更新: 那麼還有些句子
1.this research is being carried out as planned (what was planned)
===> 這裡的being是當 分詞用 而..is being carried ..是現在進行式被動這樣對嗎?
2.it is time that you started being responible for your actions and acted like an adult
==> 這裡的being是當 分詞用而 you started being responible ... 是過去進行 這樣對嗎?
更新 2: 可以的話,幫我解答一下吧~
