⑵（2007江西）A survey of the opinions of experts _____ that three hours of outdoor exercise a week _____ good for one’s health.
A.show; are   B.shows; is    C.show; is   D.shows; are
答案：B。句意：一份对专家观点进行的调查显示，每周三个小时的户外锻炼有益于人的健康。本题考查主谓一致。由a survey可知第一个空用shows，首先排除A、C两项；第二个空前的outdoor exercise看作单数，故其谓语动词用单数形式。
⑶（2011福建）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：A。句意：她具有给学生营造一种允许他们自由交流氛围的天赋。本题考查定语从句。分析句子成分可知，先行词an atmosphere与修饰它的定语从句被for her students隔开，该从句缺少指代事物的主语，故选项A符合题意。（注意：have a gift for对…有天赋）
