To my disappointment, the TV set I had was out of order again. It’s a waste of money.
A. repaired
B. repaired it
C. had repaired it
D. had repaired
网友回答
A. repaired
B. repaired it
C. had repaired it
(答案→)D. had repaired
解析：此题中含有一个定语从句，先行词为the TV set，后面是一个过去完成时态，I hadhad后缺少宾语，所以用关系词that/which，作宾语在这里省略了。此题还考查结构have sth done，所以选D。
