知識盲區 some gaps

Little Ming: Why can't I understand the questions on the exam paper?

Little Mei: Well, it seems like you have some gaps in your knowledge.

Little Ming: But I can't figure out even one question. What's going on?

Little Mei: Your knowledge gaps are quite big, that's why it's challenging for you to solve any of the questions.

小明：「為什麼考卷上的題目我看不懂？」

小美：「因為你的知識有盲區。」

小明：「那為何我沒有一題會寫？」

小美：「因為你的知識盲區太廣了。」
