问题补充：
The girl wearing a pair of dark glasses comes from a city in South China, is evident from her accent．
A. who
B. that
C. where
D. as
答案：
A. who
B. that
C. where
(答案→)D. as
解析：考查从句，做从句时，首先看一下从句是否缺少成份，如果缺少成份，就在关系代词里找；如果不缺少成份，就在关系副词里找，从句is evident from her accent．缺少成份，as在从句中做主语，先行词是a city in South China，句子意思“戴黑色眼睛的女孩来自于中国的南方城市，从她的口音可以看出”，所以选D
