问题补充：
(·陕西宝鸡二模)The British are not so familiar with different cultures and other ways of doing things, is often the case in other countries.
A. that
B. who
C. where
D. as
答案：
A. that
B. who
C. where
(答案→)D. as
解析：D考查定语从句。句意：英国人对于不同的文化和其他的行为方式不是很熟悉，在其他国家情况也是如此。先行词为前面的一句话，先行词在定语从句中作主语，且该定语从句为非限制性定语从句，故答案为D项。本题易误选A项，考生误以为本题考查“so...that...”句型，首先“so...that...”句型中的that从句前不必加逗号，此外，“so...that...”句型中that从句为结果状语从句，结果状语从句句子应完整，而本句中“is often the case in other countries”并不完整，且意思也不对，故排除A项。
