{01}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 解析：
试题分析：考查关系代词引导定语从句的区别。句意：他有为学生营造一种良好（课堂）氛围的天赋，这种氛围能够令学生交流自如。先行词an atmosphere，是物，而定语从句又缺少主语，所以用which。先行词是人时，才能用D，who；C what不能引导定语从句，可以引导名词性从句；B项定语从句中缺地点状语才能用。故A 正确。
本题选A。
{02}The sales of houses in our city fell by 40 percent last month, 48 percent __________ we don’t count low-price houses provided for poor residents. A.as B.unless C.if D.before 解析：
试题分析：考查连词和省略句：A. as当…时候，因为，正如，B. unless除非，C. if如果，D. before在…前面，句意：上个月这个城市的房屋销售下降了40%，如果不算上为贫穷居民提供的廉价房是48%。这句话是省略句，完整的是：The sales of houses in our city fell by 40 percent last month, The sales of houses in our city fell by  48 percent if we don’t count low-price houses provided for poor residents.选C。
