✓There is a lack of understanding of the importance.
「a lack of」後面應接名詞或名詞片語，而非完整的子句。應將動詞改為動名詞或使用適當的名詞形式。

×The room is lack of natural light.
✓The room lacks natural light. / The room is lacking in natural light.

在固定片語「for lack of」中，介系詞「of」必須保留，意為「由於缺乏…」。

「in lack of」不是標準英文片語。應直接使用動詞「lack」，或使用其他片語如「are short of」或「have a lack of」。
