问题补充：
Was it the restaurant where he had dinner with me, if I may ask, offered him a job?
A. that
B. where
C. which
D. when
答案：
(答案→)A. that
B. where
C. which
D. when
解析：这题考查强调句的一般问句，is/was it+强调部分+that…,这句话强调的是：the restaurant where he had dinner with me，要注意if I may ask是插入语，应该暂时不看，所以填that。句意是：如果我可以问的话，是那个他和我一起吃饭的饭店提供给他工作的吗？选A.
