To our relief, Xiaodan as well as the other children who no parents good care of in the welfare institute.
A. have; is being taken
B. has; are being taken
C. has; is being taken
D. have; are being taken
答案：
(答案→)A. have; is being taken
B. has; are being taken
C. has; is being taken
D. have; are being taken
解析：本题考查主谓一致。who引导的是定语从句，现行词是children，所以定语从句的谓语动词用复数have.第二个横线处要填的是主句的谓语动词。主句的主语是Xiaodan as well as the other children谓语动词要与Xiaodan一直，所以谓语动用单数。所以选A.这里要用被动语态。
