问题补充：
It is in Qingdao you‘ re going to pay a visit to this kind of washing machine is produced.
A. /; that
B. where; which
C. / ; where
D. that ; which
答案：
(答案→)A. /; that
B. where; which
C. / ; where
D. that ; which
解析：考查强调句与定语从句的混合使用。强调句的句型：“It is/was+被强调部分+that+其他部分。”本题强调地点状语in Qingdao，而先行词Qingdao在定语从句中当pay a visit to的宾语，而且介词to没有提前，所以（第一空格）关系词可以用that/which/不填。第二空格填that，属强调句固定搭配。句意：“这种类型的洗衣机是在青岛被生产的，青岛是你将参观的地方。”故选A。
