Question

【題目】_______ her before, he didn’t know she was his daughter.

A. Not having seen B. Having not seen

C. Not seeing D. Not to see

Answer 1

【答案】A

【解析】

考查非謂語動(dòng)詞。句意：由于以前沒有見過她，他不知道她就是他的女兒。he與see之間是邏輯上的主謂關(guān)系，表示主動(dòng)，而且see這個(gè)動(dòng)作發(fā)生在didn’t know之前，應(yīng)該用現(xiàn)在分詞的完成式作原因狀語，否定詞放在最前面，故A項(xiàng)正確。
