问题补充：
Don’t go to places where there is no fresh air.
A. such
B. so
C. those
D. which
答案：
A. such
B. so
(答案→)C. those
D. which
解析：但容易误选A。按英语习惯，受 such 修饰的名词后跟定语从句时，引导定语从句的关系词一般只能是 as，而不能是 that, which, who, where等。如：Such women as knew him thought he was charming. 认识他的女人都认为他很有魅力。此句中的 as 就不能换成that 或 who，若要使用 that 或who，则需将 such 换掉，如说成Those women who knew Tom thought he was charming.
