the boy ----- Steve,who is very good at the computer,------B

选A who is very good at the computer,作为插入语,可以先略去不看。句子简化成：the boy _____ Steve______Bill Gates in our school。B。who called,compared with。 错误选项：人名被叫,who is called, 不是完整的谓语结构,应加上, is compared with没有谓语C。calling,is compared to （错误选项：人名被叫,应是 called,）D。whose name is,compared with。 同B,不是完整的谓语结构,应加上, is compared with没有谓语所以选A,希望满意,欢迎追问,祝您进步：）
