A. who are; that
B. who is; where
C. that is; that
D. whom are; on which
答案：
A. who are; that
(答案→)B. who is; where
C. that is; that
D. whom are; on which
解析：第一空先行词为“one”(因为有“the only”修饰)，故定语从句中连系动词用“is”；第二空
尽管去掉“It was”和空格句子仍然除了，但是根据上文所问“你是第一次在哪儿认识他的”，断定不是
对地点进行强调句，故不是强调句型。结合答语中的“farm”是先行词，“work”是不及物动词，故用
关系副词“where”。句意：“他是我们班唯一一位来自那个国家的学生。我们已经认识相当一段时间了。”
“你是第一次在哪儿认识他的？”“是在我过去工作的农场上认识他的。”
