A．where; that
B．which; that
C．that; where
D．which; where
答案
答案：B
考查强调句型和定语从句。________ I had visited是非限制性定语从句，先行词是the Xichang Satellite Launch Center，定语从句缺少visited的宾语，所以用which引导，排除A,C；It was in the Xichang Satellite Launch Center________ Chang’eⅠwas launched at about 6:05 pm October 24, 2007是强调句型，所以用that引导。选B。
