The teacher, as well as three of his students, ______ taken an interest in traditional Chinese painting.
A、is
B、are
C、has
D、have
【正确答案】：C
【题目解析】：该题考查主谓一致。由边际并列连词，如as well as, rather than, together with, along with连接的名词词组作主语时，谓语动词跟前面的名词保持一致。本句中要根据前面的名词the teacher确定谓语，故选择C。再如：The President, as well as his advisors, was aware of the risk of the mission.。本句的句意为“那位老师，连同他的三个学生，都对传统国画感兴趣。”
