It was in the Beihai Park they made a date for the first time the old couple told us their love story.
A. that ,when
B. where, when
C. which, where
D. where ,that

A. that ,whenB. where, whenC. which, where(答案→)D. where ,that解析：考查句型，第一空是定语从句，先行词是the Beihai Park，在后面的定语从句they made a date for the first time中作地点状语，第二空是强调句，与It was 构成强调句，强调在北海公园句意为，在他们第一次约会的北海公园，这对老夫妻告诉了我们他们的爱情故事。

谢谢解答
