Question

Edward, you play so well. But I ________ you played the piano. A. didn’t know   B. hadn’t known

C. don’t know       D. haven’t known

Answer 1

A

解析:

A。根據句意可知，說話者是“過去”不知道，現在已經知道了，因此句子用一般過去時。句意為：愛德華，你彈得太好了。但我之前不知道你會彈鋼琴。又如：Hello! I didn’t know you were in London. How long have you been here? 你好! 我之前不知道你在倫敦。你在這里多久了?
