She has a gift for creating an atmosphere for her students________allows them to communicate freely with each other.
A．which
B．where
C．what
D．who
答案
答案：A
A [考查定语从句。句意：她具有给学生创造一种允许他们自由交流的氛围的天赋。分析句子结构可知，定语从句“________allows them to communicate freely with each other”修饰先行词atmosphere，将先行词代入句后为：The atmosphere allows them to communicate freely with each other.由此可知先行词在定语从句中作主语，而且指代物，所以须用关系代词which，故选A项。]
