John as well as the other staff members who working in this world-famous company to attend its 100th anniversary. A. is; is B. is; are C. are; is D. are; are
答案:C。考查主谓一致。句意: 约翰和这家世界著名公司的其他员工要去参加它的100周年纪念。第一空是who引导的定语从句, 先行词是the other staff members, who在从句中作主语, 从句的谓语动词单复数与先行词一致, 故用are; 第二空是谓语动词, 与主语John保持一致, 而不是the other staff members, 用is, 故选C。
