问题补充：
I have had my bike , and Im going to have somebody my radio tomorrow．
A. repair; to repair
B. repairing; to be repaired
C. repaired; repair
D. to repair; repairing
答案：
A. repair; to repair
B. repairing; to be repaired
(答案→)C. repaired; repair
D. to repair; repairing
解析：考察谓语动词用法。第一空考察了have sth done使某事被做。My bike与动词repair构成被动关系，故使用过去分词作宾语补足语。第二空考察了have sb do sth让某人做某事，在主动语态里省略了不定式符号to，变为被动语态时，要添上去。句义：我已经把我的自行车修好了。明天我让人修我的录音机。故C正确。
