问题补充：
The teacher as well as the students who fond of football, playing together.
A. is; is
B. are; are
C. is; are
D. are; is
答案：
A. is; is
B. are; are
C. is; are
(答案→)D. are; is
解析：本题第一空是一个定语从句，先行词是the students，who指代先行词在句中做主语，因为主语是the students，是复数形式，所以第一空也应该使用复数形式are；第二空是整个主句的谓语部分，本句的主语是The teacher as well as the students，谓语动词应该和as well as..前面的名词保持一致，故使用单数形式。句义：那位老师和那些喜欢足球的学生正在操场上踢足球。故D正确。
